+  <h1>Versehentlich gelöschte Daten wiederherstellen</h1>
+
+<p>Sie haben also ein Postfach gelöscht und haben keine Sicherungskopien, was?</p>
+<p>Wenn Sie Ihren Fehler innerhalb von ein paar Stunden bemerken, können Sie die Daten des Benutzers wahrscheinlich wiederherstellen.</p>
+<h3 id="sogo">SOGo<a class="headerlink" href="#sogo" title="Permanent link">&para;</a></h3>
+<p>Wir erstellen automatisch tägliche Backups (24 Stunden Intervall ab dem Hochfahren -d) in <code>/var/lib/docker/volumes/mailcowdockerized_sogo-userdata-backup-vol-1/_data/</code>.</p>
+<p><strong>Stellen Sie sicher, dass der Benutzer, den Sie wiederherstellen wollen, in Ihrer Mailcow</strong> existiert. Legen Sie sie neu an, falls sie fehlen.</p>
+<p>Kopieren Sie die Datei mit dem Namen des Benutzers, den Sie wiederherstellen wollen, nach <code>__MAILCOW_DIRECTORY__/data/conf/sogo</code>.</p>
+<p>1. Kopieren Sie die Sicherung: <code>cp /var/lib/docker/volumes/mailcowdockerized_sogo-userdata-backup-vol-1/_data/restoreme@example.org __MAILCOW_DIRECTORY__/data/conf/sogo</code></p>
+<p>2. Starten Sie <code>docker-compose exec -u sogo sogo-mailcow sogo-tool restore -F ALL /etc/sogo restoreme@example.org</code>.</p>
+<p>Führen Sie <code>sogo-tool</code> ohne Parameter aus, um nach möglichen Wiederherstellungsoptionen zu suchen.</p>
+<p>3. Löschen Sie die kopierte Sicherung, indem Sie <code>rm __MAILCOW_DIRECTORY__/data/conf/sogo</code> ausführen</p>
+<p>4. Starten Sie SOGo und Memcached neu: <code>docker-compose restart sogo-mailcow memcached-mailcow</code></p>
+<h3 id="mail">Mail<a class="headerlink" href="#mail" title="Permanent link">&para;</a></h3>
+<p>Im Falle einer versehentlichen Löschung einer Mailbox, können Sie diese (standardmäßig) 5 Tage lang wiederherstellen. Dies hängt von dem <code>MAILDIR_GC_TIME</code> Parameter in <code>mailcow.conf</code> ab.</p>
+<p>Eine gelöschte Mailbox wird in ihrer verschlüsselten Form nach <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/_garbage</code> kopiert.</p>
+<p>Der Ordner innerhalb von <code>_garbage</code> folgt der Struktur <code>[timestamp]_[domain_sanitized][user_sanitized]</code>, zum Beispiel <code>1629109708_exampleorgtest</code> im Falle von <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#116;&#101;&#115;&#116;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#111;&#114;&#103;">&#116;&#101;&#115;&#116;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#111;&#114;&#103;</a>, das am 1629109708 gelöscht wurde.</p>
+<p>Um wiederherzustellen, stellen Sie sicher, dass Sie tatsächlich auf die gleiche Mailcow wiederherstellen, von der sie gelöscht wurde, oder Sie verwenden die gleichen Verschlüsselungsschlüssel in <code>crypt-vol-1</code>.</p>
+<p><strong>Stellen Sie sicher, dass der Benutzer, den Sie wiederherstellen wollen, in Ihrer Mailcow existiert</strong>. Legen Sie sie neu an, wenn sie fehlen.</p>
+<p>Kopieren Sie die Ordner von <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/_garbage/[timestamp]_[domain_sanitized][user_sanitized]</code> zurück nach <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/[domain]/[user]</code> und synchronisieren Sie die Ordner neu und berechnen Sie die Quote neu:</p>

+<p>Sie können das mitgelieferte Skript <code>helper-scripts/backup_and_restore.sh</code> verwenden, um mailcow automatisch zu sichern.</p>
+<p>Bitte kopieren Sie dieses Skript nicht an einen anderen Ort.</p>
+<p>Um ein Backup zu starten, geben Sie "backup" als ersten Parameter an und entweder eine oder mehrere zu sichernde Komponenten als folgende Parameter.
+Sie können auch "all" als zweiten Parameter verwenden, um alle Komponenten zu sichern. Fügen Sie <code>--delete-days n</code> an, um Sicherungen zu löschen, die älter als n Tage sind.</p>
+<div class="highlight"><pre><span></span><code># Syntax:
+# ./helper-scripts/backup_and_restore.sh backup (vmail|crypt|redis|rspamd|postfix|mysql|all|--delete-days)
+
+# Alles sichern, Sicherungen älter als 3 Tage löschen
+./helper-scripts/backup_and_restore.sh backup all --delete-days 3
+
+# vmail-, crypt- und mysql-Daten sichern, Sicherungen löschen, die älter als 30 Tage sind
+./helper-scripts/backup_and_restore.sh backup vmail crypt mysql --delete-days 30
+
+# vmail sichern
+./helper-scripts/backup_and_restore.sh backup vmail
+</code></pre></div>
+<p>Das Skript wird Sie nach einem Speicherort für die Sicherung fragen. Innerhalb dieses Speicherortes wird es Ordner im Format "mailcow_DATE" erstellen.
+Sie sollten diese Ordner nicht umbenennen, um den Wiederherstellungsprozess nicht zu unterbrechen.</p>
+<p>Um ein Backup unbeaufsichtigt durchzuführen, definieren Sie MAILCOW_BACKUP_LOCATION als Umgebungsvariable bevor Sie das Skript starten:</p>
+<div class="highlight"><pre><span></span><code>MAILCOW_BACKUP_LOCATION=/opt/backup /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup all
+</code></pre></div>
+<h4 id="cronjob">Cronjob<a class="headerlink" href="#cronjob" title="Permanent link">&para;</a></h4>
+<p>Sie können das Backup-Skript regelmäßig über einen Cronjob laufen lassen. Stellen Sie sicher, dass <code>BACKUP_LOCATION</code> existiert:</p>
+<div class="highlight"><pre><span></span><code>5 4 * * * cd /opt/mailcow-dockerized/; MAILCOW_BACKUP_LOCATION=/mnt/mailcow_backups /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup mysql crypt redis --delete-days 3
+</code></pre></div>
+<p>Standardmäßig sendet Cron das komplette Ergebnis jeder Backup-Operation per E-Mail. Wenn Sie möchten, dass cron nur im Fehlerfall (Exit-Code ungleich Null) eine E-Mail sendet, können Sie den folgenden Ausschnitt verwenden. Die Pfade müssen entsprechend Ihrer Einrichtung angepasst werden (dieses Skript ist ein Beitrag des Benutzers).</p>
+<p>Das folgende Skript kann in <code>/etc/cron.daily/mailcow-backup</code> platziert werden - vergessen Sie nicht, es mit <code>chmod +x</code> als ausführbar zu markieren:</p>
+<div class="highlight"><pre><span></span><code>#!/bin/sh
+
+# Backup mailcow data
+# https://mailcow.github.io/mailcow-dockerized-docs/b_n_r_backup/

+<p>Erstellen Sie das Zielverzeichnis für mailcows Hilfsskript:
+<div class="highlight"><pre><span></span><code>mkdir -p /external_share/backups/backup_script

+<p>Cronjobs erstellen:

+# Wenn Sie wollen, benutzen Sie acl util, um die Berechtigungen einiger/aller Ordner/Dateien zu sichern: getfacl -Rn /path
+</code></pre></div></p>
+<p>Am Zielort (in diesem Fall <code>/external_share/backups</code>) möchten Sie vielleicht Snapshot-Fähigkeiten haben (ZFS, Btrfs usw.). Machen Sie täglich einen Snapshot und bewahren Sie ihn für n Tage auf, um ein konsistentes Backup zu erhalten.
+Führen Sie <strong>kein</strong> rsync auf eine Samba-Freigabe durch, Sie müssen die richtigen Berechtigungen einhalten!</p>
+<p>Zum Wiederherstellen müssen Sie rsync einfach in umgekehrter Richtung ausführen und Docker neu starten, um die Volumes erneut zu lesen. Führen Sie <code>docker-compose pull</code> und <code>docker-compose up -d</code> aus.</p>
+<p>Wenn Sie Glück haben, können Redis und MariaDB die inkonsistenten Datenbanken automatisch reparieren (wenn sie <em>inkonsistent</em> sind).
+Im Falle einer beschädigten Datenbank müssen Sie das Hilfsskript verwenden, um die inkonsistenten Elemente wiederherzustellen. Wenn die Wiederherstellung fehlschlägt, versuchen Sie, die Sicherungen zu extrahieren und die Dateien manuell zurück zu kopieren. Behalten Sie die Dateiberechtigungen bei!</p>

+<p>mailcow bietet eine einfache Möglichkeit, eine konsistente Kopie von sich selbst zu erstellen, die per rsync an einen entfernten Ort ohne Ausfallzeit übertragen werden kann.</p>
+<p>Dies kann auch verwendet werden, um Ihre mailcow auf einen neuen Server zu übertragen.</p>
+<h2 id="das-sollten-sie-wissen">Das sollten Sie wissen<a class="headerlink" href="#das-sollten-sie-wissen" title="Permanent link">&para;</a></h2>
+<p>Das bereitgestellte Skript funktioniert auf Standardinstallationen.</p>
+<p>Es kann kaputt gehen, wenn Sie nicht unterstützte Volume Overrides verwenden. Wir unterstützen das nicht und wir werden keine Hacks einbauen, die das unterstützen. Bitte erstellen und pflegen Sie einen Fork, wenn Sie Ihre Änderungen beibehalten wollen.</p>
+<p>Das Skript wird <strong>die gleichen Pfade</strong> wie Ihre Standard-Mailcow-Installation verwenden. Das ist das mailcow-Basisverzeichnis - für die meisten Nutzer <code>/opt/mailcow-dockerized</code> - sowie die Mountpoints.</p>
+<p>Um die Pfade Ihrer Quellvolumes zu finden, verwenden wir <code>docker inspect</code> und lesen das Zielverzeichnis jedes Volumes, das mit Ihrem mailcow compose Projekt verbunden ist. Das bedeutet, dass wir auch Volumes übertragen, die Sie in einer Override-Datei hinzugefügt haben. Lokale Bind-Mounts können funktionieren, müssen aber nicht.</p>
+<p>Die Verwendung von rsync mit dem <code>--delete</code> Flag. Das Ziel wird eine exakte Kopie der Quelle sein.</p>
+<p><code>mariabackup</code> wird verwendet, um eine konsistente Kopie des SQL-Datenverzeichnisses zu erstellen.</p>
+<p>Nach dem Rsync der Daten führen wir <code>docker-compose pull</code> aus und entfernen alte Image-Tags aus dem Ziel.</p>
+<p>Ihre Quelle wird zu keinem Zeitpunkt verändert.</p>
+<p>**Sie sollten sicherstellen, dass Sie die gleiche <code>/etc/docker/daemon.json</code> auf dem entfernten Ziel verwenden.</p>
+<p>Sie sollten keine Festplatten-Snapshots (z. B. über ZFS, LVM usw.) auf dem Ziel ausführen, während dieses Skript ausgeführt wird.</p>
+<p>Die Versionierung ist nicht Teil dieses Skripts, wir verlassen uns auf das Ziel (Snapshots oder Backups). Sie können dafür auch jedes andere Tool verwenden.</p>
+<h2 id="vorbereiten">Vorbereiten<a class="headerlink" href="#vorbereiten" title="Permanent link">&para;</a></h2>
+<p>Sie benötigen ein SSH-fähiges Ziel und eine Schlüsseldatei, um sich mit diesem Ziel zu verbinden. Der Schlüssel sollte nicht durch ein Passwort geschützt sein, damit das Skript unbeaufsichtigt arbeiten kann.</p>
+<p>In Ihrem mailcow-Basisverzeichnis, z.B. <code>/opt/mailcow-dockerized</code>, finden Sie eine Datei <code>create_cold_standby.sh</code>.</p>
+<p>Bearbeiten Sie diese Datei und ändern Sie die exportierten Variablen:</p>
+<div class="highlight"><pre><span></span><code>export REMOTE_SSH_KEY=/pfad/zur/keyfile
+export REMOTE_SSH_PORT=22
+export REMOTE_SSH_HOST=mailcow-backup.host.name
+</code></pre></div>
+<p>Der Schlüssel muss im Besitz von root sein und darf nur von diesem gelesen werden können.</p>
+<p>Sowohl die Quelle als auch das Ziel benötigen <code>rsync</code> &gt;= v3.1.0.
+Das Ziel muss über Docker und docker-compose <strong>v1</strong> verfügen.</p>
+<p>Das Skript wird Fehler automatisch erkennen und sich beenden.</p>
+<p>Sie können die Verbindung testen, indem Sie <code>ssh mailcow-backup.host.name -p22 -i /path/to/keyfile</code> ausführen.</p>
+<h2 id="backup-und-aktualisierung-des-cold-standby">Backup und Aktualisierung des Cold-Standby<a class="headerlink" href="#backup-und-aktualisierung-des-cold-standby" title="Permanent link">&para;</a></h2>
+<p>Starten Sie das erste Backup, dies kann je nach Verbindung eine Weile dauern:</p>
+<div class="highlight"><pre><span></span><code>bash /opt/mailcow-dockerized/create_cold_standby.sh
+</code></pre></div>
+<p>Das war einfach, nicht wahr?</p>
+<p>Das Aktualisieren des Cold-Standby ist genauso einfach:</p>
+<div class="highlight"><pre><span></span><code>bash /opt/mailcow-dockerized/create_cold_standby.sh
+</code></pre></div>
+<p>Es ist derselbe Befehl.</p>
+<h2 id="automatisierte-backups-mit-cron">Automatisierte Backups mit cron<a class="headerlink" href="#automatisierte-backups-mit-cron" title="Permanent link">&para;</a></h2>
+<p>Stellen Sie zunächst sicher, dass der <code>cron</code> Dienst aktiviert ist und läuft:</p>
+<div class="highlight"><pre><span></span><code>systemctl enable cron.service &amp;&amp; systemctl start cron.service
+</code></pre></div>
+<p>Um die Backups auf dem Cold-Standby-Server zu automatisieren, können Sie einen Cron-Job verwenden. Um die Cron-Jobs für den Root-Benutzer zu bearbeiten, führen Sie aus:</p>
+<div class="highlight"><pre><span></span><code>crontab -e
+</code></pre></div>
+<p>Fügen Sie die folgenden Zeilen hinzu, um den Cold-Standby-Server täglich um 03:00 Uhr zu synchronisieren. In diesem Beispiel werden Fehler der letzten Ausführung in einer Datei protokolliert.</p>
+<div class="highlight"><pre><span></span><code>PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+
+0 3 * * * bash /opt/mailcow-dockerized/create_cold_standby.sh 2&gt; /var/log/mailcow-coldstandby-sync.log
+</code></pre></div>
+<p>Wenn korrekt gespeichert, sollte der Cron-Job durch Eingabe angezeigt werden:</p>
+<div class="highlight"><pre><span></span><code>crontab -l
+</code></pre></div>

+<p>Unter iOS wird auch Exchange ActiveSync als Alternative zum obigen Verfahren unterstützt. Es hat den Vorteil, dass es Push-E-Mail unterstützt (d. h. Sie werden sofort über eingehende Nachrichten benachrichtigt), hat aber einige Einschränkungen, z. B. unterstützt es nicht mehr als drei E-Mail-Adressen pro Kontakt in Ihrem Adressbuch. Befolgen Sie die folgenden Schritte, wenn Sie stattdessen Exchange verwenden möchten.</p>
+<ol>
+<li>Öffnen Sie die App <em>Einstellungen</em>, tippen Sie auf <em>Mail</em>, tippen Sie auf <em>Konten</em>, tippen Sie auf <em>Konto hinzufügen</em>, wählen Sie <em>Exchange</em>.</li>
+<li>Geben Sie Ihre E-Mail Adresse<span class="client_variables_available"> (<code><span class="client_var_email"></span></code>)</span> ein und tippen Sie auf <em>Weiter</em>.</li>
+<li>Geben Sie Ihr Passwort ein und tippen Sie erneut auf <em>Weiter</em>.</li>
+<li>Tippen Sie abschließend auf <em>Speichern</em>.</li>

+  <h1>Installation</h1>
+
+<p>Sie benötigen Docker (eine Version &gt;= <code>20.10.2</code> ist erforderlich) und Docker Compose (eine Version <code>&lt;= 2.0</code> ist erforderlich).</p>
+<p><strong>1.</strong> Erfahren Sie, wie Sie <a href="https://docs.docker.com/install/">Docker</a> und <a href="https://docs.docker.com/compose/install/">Docker Compose</a> installieren.</p>
+<p>Schnelle Installation für die meisten Betriebssysteme:</p>
+<ul>
+<li>
+<p>Docker
+<div class="highlight"><pre><span></span><code>curl -sSL https://get.docker.com/ | CHANNEL=stable sh
+# Nachdem der Installationsprozess abgeschlossen ist, müssen Sie eventuell den Dienst aktivieren und sicherstellen, dass er gestartet ist (z. B. CentOS 7)
+systemctl enable --now docker
+</code></pre></div></p>
+</li>
+<li>
+<p>Docker-Zusammenstellung</p>
+</li>
+</ul>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p><strong>mailcow benötigt die neueste Version von docker-compose v1.</strong> Es wird dringend empfohlen, die untenstehenden Befehle zu verwenden, um <code>docker-compose</code> zu installieren. Paket-Manager (z.B. <code>apt</code>, <code>yum</code>) werden <strong>wahrscheinlich</strong> nicht die richtige Version liefern.
+Hinweis: Dieser Befehl lädt docker-compose aus dem offiziellen Docker-Github-Repository herunter und ist eine sichere Methode. Das Snippet ermittelt die neueste unterstützte Version von mailcow. In fast allen Fällen ist dies die letzte verfügbare Version (Ausnahmen sind kaputte Versionen oder größere Änderungen, die noch nicht von mailcow unterstützt werden).</p>
+</div>
+<div class="highlight"><pre><span></span><code>curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) &gt; /usr/local/bin/docker-compose
+chmod +x /usr/local/bin/docker-compose
+</code></pre></div>
+<p>Bitte verwenden Sie die neueste verfügbare Docker-Engine und nicht die Engine, die mit Ihrem Distros-Repository ausgeliefert wird.</p>
+<p><strong>1.1.1.</strong> Auf SELinux-aktivierten Systemen, z.B. CentOS 7:</p>
+<ul>
+<li>Prüfen Sie, ob das Paket "container-selinux" auf Ihrem System vorhanden ist:</li>
+</ul>
+<div class="highlight"><pre><span></span><code>rpm -qa | grep container-selinux
+</code></pre></div>
+<p>Wenn der obige Befehl eine leere oder keine Ausgabe liefert, sollten Sie es über Ihren Paketmanager installieren.</p>
+<ul>
+<li>Prüfen Sie, ob Docker SELinux-Unterstützung aktiviert hat:</li>
+</ul>
+<div class="highlight"><pre><span></span><code>docker info | grep selinux
+</code></pre></div>
+<p>Wenn der obige Befehl eine leere oder keine Ausgabe liefert, erstellen oder bearbeiten Sie <code>/etc/docker/daemon.json</code> und fügen Sie <code>"selinux-enabled": true</code> hinzu. Beispielhafter Inhalt der Datei:</p>
+<div class="highlight"><pre><span></span><code>{
+  &quot;selinux-enabled&quot;: true
+}
+</code></pre></div>
+<p>Starten Sie den Docker-Daemon neu und überprüfen Sie, ob SELinux nun aktiviert ist.</p>
+<p>Dieser Schritt ist erforderlich, um sicherzustellen, dass die Mailcows-Volumes richtig gekennzeichnet sind, wie in der Compose-Datei angegeben.
+Wenn Sie daran interessiert sind, wie das funktioniert, können Sie sich die Readme-Datei von <a href="https://github.com/containers/container-selinux">https://github.com/containers/container-selinux</a> ansehen, die auf viele nützliche Informationen zu diesem Thema verweist.</p>
+<p><strong>2.</strong> Klonen Sie den Master-Zweig des Repositorys und stellen Sie sicher, dass Ihre umask gleich 0022 ist. Bitte klonen Sie das Repository als root-Benutzer und kontrollieren Sie auch den Stack als root. Wir werden die Attribute - wenn nötig - ändern, während wir die Container automatisch boosten und sicherstellen, dass alles gesichert ist. Das update.sh-Skript muss daher ebenfalls als root ausgeführt werden. Es kann notwendig sein, den Besitz und andere Attribute von Dateien zu ändern, auf die Sie sonst keinen Zugriff haben. <strong>Wir geben die Berechtigungen für jede exponierte Anwendung</strong> auf und führen einen exponierten Dienst nicht als root aus! Wenn Sie den Docker-Daemon als Nicht-Root-Benutzer steuern, erhalten Sie keine zusätzliche Sicherheit. Der unprivilegierte Benutzer wird die Container ebenfalls als root spawnen. Das Verhalten des Stacks ist identisch.</p>
+<div class="highlight"><pre><span></span><code>$ su
+# umask
+0022 # &lt;- Überprüfen, dass es 0022 ist
+# cd /opt
+# git clone https://github.com/mailcow/mailcow-dockerized
+# cd mailcow-dockerized
+</code></pre></div>
+<p><strong>3.</strong> Erzeugen Sie eine Konfigurationsdatei. Verwende einen FQDN (<code>host.domain.tld</code>) als Hostname, wenn du gefragt wirst.
+<div class="highlight"><pre><span></span><code>./generate_config.sh
+</code></pre></div></p>
+<p><strong>4.</strong> Ändern Sie die Konfiguration, wenn Sie das wollen oder müssen.
+<div class="highlight"><pre><span></span><code>nano mailcow.conf
+</code></pre></div>
+Wenn Sie planen, einen Reverse Proxy zu verwenden, können Sie zum Beispiel HTTPS an 127.0.0.1 auf Port 8443 und HTTP an 127.0.0.1 auf Port 8080 binden.</p>
+<p>Möglicherweise müssen Sie einen vorinstallierten MTA stoppen, der Port 25/tcp blockiert. Siehe <a href="../../post_installation/firststeps-local_mta/">dieses Kapitel</a>, um zu erfahren, wie man Postfix rekonfiguriert, um nach einer erfolgreichen Installation neben mailcow zu laufen.</p>
+<p>Einige Updates modifizieren mailcow.conf und fügen neue Parameter hinzu. Es ist schwer, in der Dokumentation den Überblick zu behalten. Bitte überprüfen Sie deren Beschreibung und fragen Sie, wenn Sie unsicher sind, in den bekannten Kanälen nach Rat.</p>
+<p><strong>4.1.</strong> Benutzer mit einer MTU ungleich 1500 (z.B. OpenStack):</p>
+<p><strong>Wenn Sie auf Probleme und seltsame Phänomene stoßen, überprüfen Sie bitte Ihre MTU.</strong></p>
+<p>Bearbeiten Sie <code>docker-compose.yml</code> und ändern Sie die Netzwerkeinstellungen entsprechend Ihrer MTU.
+Fügen Sie den neuen Parameter driver_opts wie folgt hinzu:
+<div class="highlight"><pre><span></span><code>Netzwerke:
+  mailcow-network:
+    ...
+    driver_opts:
+      com.docker.network.driver.mtu: 1450
+    ...
+</code></pre></div></p>
+<p><strong>4.2.</strong> Benutzer ohne ein IPv6-aktiviertes Netzwerk auf ihrem Hostsystem:</p>
+<p><strong>Einschalten von IPv6. Endlich.</strong></p>
+<p>Wenn Sie kein IPv6-fähiges Netzwerk auf Ihrem Host haben und Sie sich nicht um ein besseres Internet kümmern (hehe), ist es empfehlenswert, <a href="../../post_installation/firststeps-disable_ipv6/">IPv6 zu deaktivieren</a> für das mailcow-Netzwerk, um unvorhergesehene Probleme zu vermeiden.</p>
+<p><strong>5.</strong> Ziehen Sie die Images und führen Sie die Compose-Datei aus. Der Parameter <code>-d</code> wird mailcow starten: dockerized detached:
+<div class="highlight"><pre><span></span><code>docker-compose pull
+docker-compose up -d
+</code></pre></div></p>
+<p>Geschafft!</p>
+<p>Sie können nun auf <strong>https://${MAILCOW_HOSTNAME}</strong> mit den Standard-Zugangsdaten <code>admin</code> + Passwort <code>moohoo</code> zugreifen.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Wenn Sie mailcow nicht hinter einem Reverse Proxy verwenden, sollten Sie <a href="../../manual-guides/u_e-80_to_443/">alle HTTP-Anfragen auf HTTPS umleiten</a>.</p>
+</div>
+<p>Die Datenbank wird sofort initialisiert, nachdem eine Verbindung zu MySQL hergestellt werden kann.</p>
+<p>Ihre Daten bleiben in mehreren Docker-Volumes erhalten, die nicht gelöscht werden, wenn Sie Container neu erstellen oder löschen. Führen Sie <code>docker volume ls</code> aus, um eine Liste aller Volumes zu sehen. Sie können <code>docker-compose down</code> sicher ausführen, ohne persistente Daten zu entfernen.</p>

+
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Diese Anleitung geht davon aus, dass Sie beabsichtigen, einen bestehenden Mailcow-Server (Quelle) auf einen brandneuen, leeren Server (Ziel) zu migrieren. Sie kümmert sich nicht um die Erhaltung bestehender Daten auf dem Zielserver und löscht alles innerhalb von <code>/var/lib/docker/volumes</code> und somit alle Docker-Volumes, die Sie bereits eingerichtet haben.</p>
+</div>
+<div class="admonition tip">
+<p class="admonition-title">Tip</p>
+<p>Alternativ können Sie das Skript <code>./helper-scripts/backup_and_restore.sh</code> verwenden, um ein vollständiges Backup auf der Quellmaschine zu erstellen, dann installieren Sie mailcow auf der Zielmaschine wie gewohnt, kopieren Sie Ihre <code>mailcow.conf</code> und verwenden Sie das gleiche Skript, um Ihr Backup auf der Zielmaschine wiederherzustellen.</p>
+</div>
+<p><strong>1.</strong> 
+Installieren Sie <a href="https://docs.docker.com/engine/installation/linux/">Docker</a> und <a href="https://docs.docker.com/compose/install/">Docker Compose</a> auf Ihrem neuen Server.</p>
+<p>Schnelle Installation für die meisten Betriebssysteme:</p>
+<ul>
+<li>
+<p>Docker
+<div class="highlight"><pre><span></span><code>curl -sSL https://get.docker.com/ | CHANNEL=stable sh
+# Nachdem der Installationsprozess abgeschlossen ist, müssen Sie den Dienst aktivieren und sicherstellen, dass er gestartet ist (z. B. CentOS 7)
+systemctl enable docker.service
+</code></pre></div></p>
+</li>
+<li>
+<p>docker-compose
+<div class="highlight"><pre><span></span><code>curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) &gt; /usr/local/bin/docker-compose
+chmod +x /usr/local/bin/docker-compose
+</code></pre></div></p>
+</li>
+</ul>
+<p>Bitte verwenden Sie die neueste verfügbare Docker-Engine und nicht die Engine, die mit Ihrem Distros-Repository ausgeliefert wird.</p>
+<p><strong>2.</strong> Stoppen Sie Docker und stellen Sie sicher, dass Docker gestoppt wurde:
+<div class="highlight"><pre><span></span><code>systemctl stop docker.service
+systemctl status docker.service
+</code></pre></div></p>
+<p><strong>3.</strong> Führen Sie die folgenden Befehle auf dem Quellcomputer aus (achten Sie darauf, die abschließenden Schrägstriche im ersten Pfadparameter wie unten gezeigt hinzuzufügen!) - <strong>WARNUNG: Dieser Befehl löscht alles, was bereits unter <code>/var/lib/docker/volumes</code> auf dem Zielrechner existiert</strong>:
+<div class="highlight"><pre><span></span><code>rsync -aHhP --numeric-ids --delete /opt/mailcow-dockerized/ root@target-machine.example.com:/opt/mailcow-dockerized
+rsync -aHhP --numeric-ids --delete /var/lib/docker/volumes/ root@target-machine.example.com:/var/lib/docker/volumes
+</code></pre></div></p>
+<p><strong>4.</strong> Schalten Sie mailcow ab und stoppen Sie Docker auf dem Quellrechner.
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+docker-compose herunterfahren
+systemctl stop docker.service
+</code></pre></div></p>
+<p>**Wiederholen Sie Schritt 3 mit denselben Befehlen. Dies wird viel schneller gehen als beim ersten Mal.</p>
+<p><strong>6.</strong> Wechseln Sie auf den Zielrechner und starten Sie Docker.
+<div class="highlight"><pre><span></span><code>systemctl start docker.service
+</code></pre></div></p>
+<p><strong>7.</strong> Ziehen Sie nun die mailcow Docker-Images auf den Zielrechner.
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+docker-compose pull
+</code></pre></div></p>
+<p><strong>8.</strong> Starten Sie den gesamten mailcow-Stack und alles sollte fertig sein!
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div></p>
+<p><strong>9.</strong> Zum Schluss ändern Sie Ihre DNS-Einstellungen so, dass sie auf den Zielserver zeigen.</p>

+<p>Ein Update-Skript in Ihrem mailcow-dockerized Verzeichnis kümmert sich um Updates.</p>
+<p>Aber benutzen Sie es mit Bedacht! Wenn Sie denken, dass Sie viele Änderungen am mailcow-Code vorgenommen haben, sollten Sie die manuelle Update-Anleitung unten verwenden.</p>
+<p>Führen sie das Update-Skript aus:
+<div class="highlight"><pre><span></span><code>./update.sh
+</code></pre></div></p>
+<p>Wenn es nötig ist, wird es Sie fragen, wie Sie fortfahren möchten.
+Merge-Fehler werden gemeldet.
+Einige kleinere Konflikte werden automatisch korrigiert (zugunsten des mailcow: dockerized repository code).</p>
+<h3 id="optionen">Optionen<a class="headerlink" href="#optionen" title="Permanent link">&para;</a></h3>
+<div class="highlight"><pre><span></span><code># Optionen können kombiniert werden

+./update.sh --no-update-compose

+./update.sh --gc

+# - Update mit der Merge-Strategie-Option &quot;ours&quot; statt &quot;theirs&quot;

+<p>Diese Funktion kann wieder aktiviert werden, indem <code>ACL_ANYONE</code> auf <code>allow</code> in mailcow.conf gesetzt wird:</p>

+  <h1>Urlaubsantworten für Catchall-Adressen</h1>
+
+<p>Der Dovecot-Parameter <code>sieve_vacation_dont_check_recipient</code> - der in mailcow-Konfigurationen vor dem 21. Juli 2021 standardmäßig auf <code>yes</code> gesetzt war - erlaubt Urlaubsantworten auch dann, wenn eine Mail an nicht existierende Mailboxen wie Catch-All-Adressen gesendet wird.</p>
+<p>Wir haben uns entschlossen, diesen Parameter wieder auf <code>nein</code> zu setzen und dem Benutzer zu erlauben, die Empfängeradresse zu spezifizieren, die eine Urlaubsantwort auslöst. Die auslösenden Empfänger können auch in SOGos Autoresponder-Funktion konfiguriert werden.</p>

+  <h1>Löschen der Mails eines Benutzers</h1>
+
+<p>Wenn Sie alte Mails aus den Ordnern <code>.Junk</code> oder <code>.Trash</code> löschen wollen oder vielleicht alle gelesenen Mails, die älter als eine bestimmte Zeitspanne sind, können Sie das dovecot-Tool doveadm <a href="https://wiki.dovecot.org/Tools/Doveadm/Expunge">man doveadm-expunge</a> verwenden.</p>
+<h2 id="der-manuelle-weg">Der manuelle Weg<a class="headerlink" href="#der-manuelle-weg" title="Permanent link">&para;</a></h2>
+<p>Dann wollen wir mal loslegen:</p>
+<p>Löschen Sie die Mails eines Benutzers im Junk-Ordner, die <strong>gelesen</strong> und <strong>älter</strong> als 4 Stunden sind</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm expunge -u &#39;mailbox@example.com&#39; mailbox &#39;Junk&#39; SEEN not SINCE 4h

+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 7d

+<p>Löscht <strong>alle</strong> Mails (aller Benutzer) in <strong>allen</strong> Ordnern, die <strong>älter</strong> als 52 Wochen sind (internes Datum der Mail, nicht das Datum, an dem sie auf dem System gespeichert wurde =&gt; <code>before</code> statt <code>savedbefore</code>). Nützlich zum Löschen sehr alter Mails in allen Benutzern und Ordnern (daher besonders nützlich für GDPR-Compliance).</p>

+<p>Wenn Sie eine solche Aufgabe automatisieren wollen, können Sie einen Cron-Job auf Ihrem Rechner erstellen, der ein Skript wie das folgende aufruft:</p>
+<div class="highlight"><pre><span></span><code>#!/bin/bash
+# Pfad zu mailcow-dockerized, z.B. /opt/mailcow-dockerized
+cd /pfad/zu/ihrem/mailcow-dockerized
+
+/usr/local/bin/docker-compose exec -T dovecot-mailcow doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 2w
+/usr/local/bin/docker-compose exec -T dovecot-mailcow doveadm expunge -A mailbox &#39;Junk&#39; SEEN not SINCE 12h
+[...]
+</code></pre></div>
+<p>Um einen Cronjob zu erstellen, können Sie <code>crontab -e</code> ausführen und etwas wie das Folgende einfügen, um ein Skript auszuführen:</p>
+<div class="highlight"><pre><span></span><code># Jeden Tag um 04:00 Uhr morgens ausführen.
+0 4 * * * /pfad/zu/ihr/expunge_mailboxes.sh
+</code></pre></div>
+<h3 id="uber-docker-job-scheduler">über Docker Job Scheduler<a class="headerlink" href="#uber-docker-job-scheduler" title="Permanent link">&para;</a></h3>
+<p>Um dies mit einem Docker-Job-Scheduler zu archivieren, verwenden Sie diese docker-compose.override.yml mit Ihrer Mailcow: </p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+
+services:
+
+  ofelia:
+    image: mcuadros/ofelia:latest
+    restart: always
+    command: daemon --docker
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock:ro   
+    network_mode: none
+
+  dovecot-mailcow:
+    labels:
+      - &quot;ofelia.enabled=true&quot;
+      - &quot;ofelia.job-exec.dovecot-expunge-trash.schedule=0 4 * * *&quot;
+      - &quot;ofelia.job-exec.dovecot-expunge-trash.command=doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 2w&quot;
+      - &quot;ofelia.job-exec.dovecot-expunge-trash.tty=false&quot;
+</code></pre></div>
+<p>Der Job-Controller braucht nur Zugriff auf den Docker Control Socket, um das Verhalten von "exec" zu emulieren. Dann fügen wir unserem Dovecot-Container ein paar Labels hinzu, um den Job-Scheduler zu aktivieren und ihm in einem Cron-kompatiblen Scheduling-Format mitzuteilen, wann er laufen soll. Wenn Sie Probleme mit dem Scheduling-String haben, können Sie <a href="https://crontab.guru/">crontab guru</a> verwenden. 
+Diese docker-compose.override.yml löscht jeden Tag um 4 Uhr morgens alle Mails, die älter als 2 Wochen sind, aus dem Ordner "Junk". Um zu sehen, ob alles richtig gelaufen ist, können Sie nicht nur in Ihrer Mailbox nachsehen, sondern auch im Docker-Log von Ofelia, ob es etwa so aussieht:</p>
+<div class="highlight"><pre><span></span><code>common.go:124 ▶ NOTICE [Job &quot;dovecot-expunge-trash&quot; (8759567efa66)] Started - doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 2w,
+common.go:124 ▶ NOTICE [Job &quot;dovecot-expunge-trash&quot; (8759567efa66)] Finished in &quot;285.032291ms&quot;, failed: false, skipped: false, error: none,
+</code></pre></div>
+<p>Wenn der Vorgang fehlgeschlagen ist, wird dies angegeben und die Ausgabe von doveadm im Protokoll aufgeführt, um Ihnen die Fehlersuche zu erleichtern.</p>
+<p>Falls Sie weitere Jobs hinzufügen wollen, stellen Sie sicher, dass Sie den "dovecot-expunge-trash"-Teil nach "ofelia.job-exec." in etwas anderes ändern, er definiert den Namen des Jobs. Die Syntax der Labels finden Sie unter <a href="https://github.com/mcuadros/ofelia">mcuadros/ofelia</a>.</p>

+  <h1>FTS (Solr)</h1>
+
+<h2 id="fts-solr">FTS Solr<a class="headerlink" href="#fts-solr" title="Permanent link">&para;</a></h2>
+<p>Solr wird für Setups mit Speicher &gt;= 3,5 GiB verwendet, um eine Volltextsuche in Dovecot zu ermöglichen.</p>
+<p>Bitte beachten Sie, dass Anwendungen wie Solr <em>vielleicht</em> von Zeit zu Zeit gewartet werden müssen.</p>
+<p>Außerdem verbraucht Solr eine Menge RAM, abhängig von der Nutzung Ihres Servers. Bitte vermeiden Sie es auf Maschinen mit weniger als 3 GB RAM.</p>
+<p>Die Standard-Heap-Größe (1024 M) ist in mailcow.conf definiert.</p>
+<p>Da wir in Docker laufen und unsere Container mit dem "restart: always" Flag erstellen, wird eine oom Situation zumindest nur einen Neustart des Containers auslösen.</p>
+<h3 id="fts-bezogene-dovecot-befehle">FTS-bezogene Dovecot-Befehle<a class="headerlink" href="#fts-bezogene-dovecot-befehle" title="Permanent link">&para;</a></h3>
+<p><div class="highlight"><pre><span></span><code># Einzelbenutzer
+docker-compose exec dovecot-mailcow doveadm fts rescan -u user@domain
+# alle Benutzer
+docker-compose exec dovecot-mailcow doveadm fts rescan -A
+</code></pre></div>
+Dovecot Wiki: "Scannt, welche Mails im Volltextsuchindex vorhanden sind und vergleicht diese mit den tatsächlich in den Postfächern vorhandenen Mails. Dies entfernt Mails aus dem Index, die bereits gelöscht wurden und stellt sicher, dass der nächste doveadm-Index alle fehlenden Mails (falls vorhanden) indiziert."</p>
+<p>Dies indiziert <strong>nicht</strong> eine Mailbox neu. Es repariert im Grunde einen gegebenen Index.</p>
+<p>Wenn Sie die Daten sofort neu indizieren wollen, können Sie den folgenden Befehl ausführen, wobei '*' auch eine Postfachmaske wie 'Sent' sein kann. Sie müssen diese Befehle nicht ausführen, aber es wird die Dinge ein wenig beschleunigen:</p>
+<div class="highlight"><pre><span></span><code># einzelner Benutzer
+docker-compose exec dovecot-mailcow doveadm index -u user@domain &#39;*&#39;
+# alle Benutzer, aber offensichtlich langsamer und gefährlicher
+docker-compose exec dovecot-mailcow doveadm index -A &#39;*&#39;
+</code></pre></div>
+<p>Dies <strong>wird</strong> einige Zeit in Anspruch nehmen, abhängig von Ihrer Maschine und Solr kann oom ausführen, überwachen Sie es!</p>
+<p>Da die Neuindizierung sehr sinnvoll ist, haben wir sie nicht in die mailcow UI integriert. Sie müssen sich um eventuelle Fehler beim Re-Indizieren einer Mailbox kümmern.</p>
+<h3 id="loschen-der-mailbox-daten">Löschen der Mailbox-Daten<a class="headerlink" href="#loschen-der-mailbox-daten" title="Permanent link">&para;</a></h3>
+<p>mailcow wird die Indexdaten eines Benutzers löschen, wenn eine Mailbox gelöscht wird.</p>
+<hr />
+<h2 id="fts-xapian-release-2022">FTS Xapian (Release 2022)<a class="headerlink" href="#fts-xapian-release-2022" title="Permanent link">&para;</a></h2>
+<p>Der Solr-Ersatz Xapian befindet sich derzeit in der Entwicklungs-/Testphase.</p>
+<p>Xapian ist viel effizienter als Solr, da es nicht auf Java basiert.</p>
+<p>Xapian ist auch nicht so anfällig für Sicherheitslücken (die bei Java-Anwendungen häufig auftreten).</p>
+<p>Der gravierendste Unterschied zwischen den beiden FTS ist, dass Xapian (im Gegensatz zu Solr) keinen extra Container mehr benötigt, sondern fortan direkt in Dovecot (als Plugin) läuft.</p>
+<p>Sollten Sie mehr über das Xapian Plugin wissen wollen schauen Sie <a href="https://github.com/grosjo/fts-xapian">hier</a>.</p>
+<p><strong>Alle Einstellungen der mailcow.conf, die Solr betreffen, werden auf Xapian umgestellt</strong>.</p>

+<p>Standardmäßig sendet Dovecot eine "Ich bin noch da"-Benachrichtigung an jeden Client, der eine offene Verbindung mit Dovecot hat, um Mails so schnell wie möglich zu erhalten, ohne sie manuell abzufragen (IMAP PUSH). Diese Benachrichtigung wird durch die Einstellung <a href="https://wiki.dovecot.org/Timeouts"><code>imap_idle_notify_interval</code></a> gesteuert, die standardmäßig auf 2 Minuten eingestellt ist. </p>
+<p>Ein kurzes Intervall führt dazu, dass der Client viele Nachrichten für diese Verbindung erhält, was für mobile Geräte schlecht ist, da jedes Mal, wenn das Gerät diese Nachricht erhält, die Mailing-App aufwachen muss. Dies kann zu einer unnötigen Entladung der Batterie führen.</p>
+<h2 id="bearbeiten-sie-den-wert">Bearbeiten Sie den Wert<a class="headerlink" href="#bearbeiten-sie-den-wert" title="Permanent link">&para;</a></h2>
+<h3 id="konfiguration-andern">Konfiguration ändern<a class="headerlink" href="#konfiguration-andern" title="Permanent link">&para;</a></h3>
+<p>Erstellen Sie eine neue Datei <code>data/conf/dovecot/extra.conf</code> (oder bearbeiten Sie sie, falls sie bereits existiert).
+Fügen Sie die Einstellung ein, gefolgt von dem neuen Wert. Um zum Beispiel das Intervall auf 5 Minuten zu setzen, können Sie Folgendes eingeben:</p>
+<div class="highlight"><pre><span></span><code>imap_idle_notify_interval = 5 mins
+</code></pre></div>
+<p>29 Minuten ist der maximale Wert, den der <a href="https://tools.ietf.org/html/rfc2177">entsprechende RFC</a> erlaubt.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Dies ist keine Standardeinstellung in mailcow, da wir nicht wissen, wie diese Einstellung das Verhalten anderer Clients verändert. Seien Sie vorsichtig, wenn Sie dies ändern und ein anderes Verhalten beobachten.</p>
+</div>
+<h3 id="dovecot-neu-laden">Dovecot neu laden<a class="headerlink" href="#dovecot-neu-laden" title="Permanent link">&para;</a></h3>
+<p>Nun laden Sie Dovecot neu:</p>

+</code></pre></div>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Sie können den Wert dieser Einstellung überprüfen mit 
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow dovecot -a | grep &quot;imap_idle_notify_interval&quot;
+</code></pre></div>
+Wenn Sie den Wert nicht geändert haben, sollte er auf 2m stehen. Wenn Sie ihn geändert haben, sollten Sie den neuen Wert sehen.</p>

+<p>Hier ist nur eine unsortierte Liste von nützlichen <code>doveadm</code>-Befehlen, die nützlich sein könnten.</p>
+<h2 id="doveadm-quota">doveadm quota<a class="headerlink" href="#doveadm-quota" title="Permanent link">&para;</a></h2>
+<p>Die Befehle <code>quota get</code> und <code>quota recalc</code><sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup> werden verwendet, um die Quota-Nutzung des aktuellen Benutzers anzuzeigen oder neu zu berechnen. Die angezeigten Werte sind in <em>Kilobytes</em>.</p>
+<p>Um den aktuellen Quota-Status für einen Benutzer / eine Mailbox aufzulisten, tun Sie folgendes:</p>
+<div class="highlight"><pre><span></span><code>doveadm quota get -u &#39;mailbox@example.org&#39;
+</code></pre></div>
+<p>Um den Quota-Speicherwert für <strong>alle</strong> Benutzer aufzulisten, tun Sie folgendes:</p>
+<div class="highlight"><pre><span></span><code>doveadm quota get -A |grep &quot;STORAGE&quot;
+</code></pre></div>
+<p>Berechnen Sie die Quota-Nutzung eines einzelnen Benutzers neu:</p>
+<div class="highlight"><pre><span></span><code>doveadm quota recalc -u &#39;mailbox@example.org&#39;
+</code></pre></div>
+<h2 id="doveadm-search">doveadm search<a class="headerlink" href="#doveadm-search" title="Permanent link">&para;</a></h2>
+<p>Der Befehl <code>doveadm search</code><sup id="fnref:2"><a class="footnote-ref" href="#fn:2">2</a></sup> wird verwendet, um Nachrichten zu finden, die Ihrer Anfrage entsprechen. Er kann den Benutzernamen, die Mailbox-GUID / -UID und die Nachrichten-GUIDs / -UIDs zurückgeben.</p>
+<p>Um die Anzahl der Nachrichten im <strong>.Trash</strong> Ordner eines Benutzers zu sehen:</p>
+<div class="highlight"><pre><span></span><code>doveadm search -A mailbox &#39;Trash&#39; | awk &#39;{print $1}&#39; | sort | uniq -c
+</code></pre></div>
+<p>Alle Nachrichten im <strong>Postfach</strong> eines Benutzers anzeigen, die älter als 90 Tage sind:</p>
+<div class="highlight"><pre><span></span><code>doveadm search -u &#39;mailbox@example.org&#39; mailbox &#39;INBOX&#39; savedbefore 90d
+</code></pre></div>
+<p>Zeige <strong>alle Nachrichten</strong> in <strong>beliebigen Ordnern</strong>, die <strong>älter</strong> sind als 30 Tage für <code>mailbox@example.org</code>:</p>
+<div class="highlight"><pre><span></span><code>doveadm search -u &#39;mailbox@example.org&#39; mailbox &quot;*&quot; savedbefore 30d

+  <h1>Öffentliche Ordner</h1>
+
+<p>Erstellen Sie einen neuen öffentlichen Namespace "Public" und eine Mailbox "Develcow" innerhalb dieses Namespaces:</p>
+<p>Bearbeiten oder erstellen Sie <code>data/conf/dovecot/extra.conf</code>, fügen Sie hinzu:</p>
+<div class="highlight"><pre><span></span><code>namespace {
+  type = public
+  separator = /
+  prefix = Public/
+  location = maildir:/var/vmail/public:INDEXPVT=~/public
+  subscriptions = yes
+  mailbox &quot;Develcow&quot; {
+    auto = subscribe
+  }
+}
+</code></pre></div>
+<p><code>:INDEXPVT=~/public</code> kann weggelassen werden, wenn die Flags, die pro Benutzer gesehen werden, nicht gewünscht sind.</p>
+<p>Die neue Mailbox im öffentlichen Namensraum wird von den Benutzern automatisch abonniert.</p>
+<p>Um allen authentifizierten Benutzern vollen Zugriff auf das neue Postfach (nicht auf den gesamten Namespace) zu gewähren, führen Sie aus:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm acl set -A &quot;Public/Develcow&quot; &quot;authenticated&quot; lookup read write write-seen write-deleted insert post delete expunge create
+</code></pre></div>
+<p>Passen Sie den Befehl an Ihre Bedürfnisse an, wenn Sie detailliertere Rechte pro Benutzer vergeben möchten (verwenden Sie z.B. <code>-u user@domain</code> anstelle von <code>-A</code>).</p>
+<h2 id="erlaube-authentifizierten-benutzern-den-zugriff-auf-den-gesamten-offentlichen-namespace">Erlaube authentifizierten Benutzern den Zugriff auf den gesamten öffentlichen Namespace<a class="headerlink" href="#erlaube-authentifizierten-benutzern-den-zugriff-auf-den-gesamten-offentlichen-namespace" title="Permanent link">&para;</a></h2>
+<p>Um allen authentifizierten Benutzern vollen Zugriff auf den gesamten öffentlichen Namespace und seine Unterordner zu gewähren, erstellen Sie eine neue Datei <code>dovecot-acl</code> im Namespace-Stammverzeichnis:</p>
+<p>Öffnen/bearbeiten/erstellen Sie <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/public/dovecot-acl</code> (passen Sie den Pfad entsprechend an), um die globale ACL-Datei mit dem folgenden Inhalt zu erstellen:</p>
+<div class="highlight"><pre><span></span><code>authenticated kxeilprwts
+</code></pre></div>
+<p>kxeilprwts" ist gleichbedeutend mit "lookup read write write-seen write-deleted insert post delete expunge create".</p>
+<p>Sie können <code>doveadm acl set -u user@domain "Public/Develcow" user=user@domain lookup read</code> verwenden, um den Zugriff für einen einzelnen Benutzer zu beschränken. Sie können es auch umdrehen und den Zugriff für alle Benutzer auf "lr" beschränken und nur einigen Benutzern vollen Zugriff gewähren.</p>

+  <h1>Statischer Hauptbenutzer</h1>
+
+<p>Zufällige Master-Benutzernamen und Passwörter werden automatisch bei jedem Neustart von dovecot-mailcow erstellt.</p>
+<p><strong>Das wird empfohlen und sollte nicht geändert werden.</strong></p>
+<p>Wenn der Benutzer trotzdem statisch sein soll, geben Sie bitte zwei Variablen in <code>mailcow.conf</code> an.</p>
+<p><strong>Beide</strong> Parameter dürfen nicht leer sein!</p>
+<div class="highlight"><pre><span></span><code>DOVECOT_MASTER_USER=mymasteruser
+DOVECOT_MASTER_PASS=mysecretpass
+</code></pre></div>
+<p>Führen Sie <code>docker-compose up -d</code> aus, um Ihre Änderungen zu übernehmen.</p>
+<p>Der statische Master-Benutzername wird zu <code>DOVECOT_MASTER_USER@mailcow.local</code> erweitert.</p>
+<p>Um sich als <code>test@example.org</code> anzumelden, würde dies <code>test@example.org*mymasteruser@mailcow.local</code> mit dem oben angegebenen Passwort entsprechen.</p>
+<p>Eine Anmeldung bei SOGo ist mit diesem Benutzernamen nicht möglich. Für Admins steht eine Click-to-Login-Funktion für SOGo zur Verfügung, wie [hier] beschrieben (<a href="https://mailcow.github.io/mailcow-dockerized-docs/debug-admin_login_sogo/">https://mailcow.github.io/mailcow-dockerized-docs/debug-admin_login_sogo/</a>)
+Es wird kein Hauptbenutzer benötigt.</p>

+<p>Neuere Docker-Versionen scheinen sich über bestehende Volumes zu beschweren. Man kann dies vorübergehend beheben, indem man das bestehende Volume entfernt und mailcow mit der Override-Datei startet. Aber es scheint nach einem Neustart problematisch zu sein (muss bestätigt werden).</p>
+</div>
+<p>Ein einfacher, schmutziger, aber stabiler Workaround ist es, mailcow zu stoppen (<code>docker-compose down</code>), <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data</code> zu entfernen und einen neuen Link zu Ihrem entfernten Dateisystem zu erstellen, zum Beispiel:</p>
+<div class="highlight"><pre><span></span><code>mv /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data_backup
+ln -s /mnt/volume-xy/vmail_data /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data
+</code></pre></div>
+<p>Starten Sie anschließend mailcow.</p>

+<h2 id="der-alte-weg">Der "alte" Weg<a class="headerlink" href="#der-alte-weg" title="Permanent link">&para;</a></h2>
+<p>Wenn man einen anderen Ordner für das vmail-Volume verwenden möchte, kann man eine <code>docker-compose.override.yml</code> Datei erstellen und den folgenden Inhalt hinzufügen:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+volumes:
+  vmail-vol-1:

+<li>Kopieren Sie den Inhalt des <code>Mountpoint</code>-Ordners an den neuen Speicherort (z.B. <code>/data/mailcow/vmail</code>) mit <code>cp -a</code>, <code>rsync -a</code> oder einem ähnlichen, nicht strikten Kopierbefehl</li>
+<li>Stoppen Sie mailcow durch Ausführen von <code>docker-compose down</code> aus Ihrem mailcow-Stammverzeichnis (z.B. <code>/opt/mailcow-dockerized</code>)</li>
+<li>Erstellen Sie die Datei <code>docker-compose.override.yml</code>, bearbeiten Sie den Gerätepfad entsprechend</li>
+<li>Löschen Sie den aktuellen vmail-Ordner: <code>docker volume rm mailcowdockerized_vmail-vol-1</code></li>

+<p>Der Dateiname, der für eine neue Site verwendet wird, ist nicht wichtig, solange der Dateiname eine .conf-Erweiterung trägt.</p>
+<p>Es ist auch möglich, die Konfiguration der Standarddatei <code>site.conf</code> Datei zu erweitern:</p>
+<div class="highlight"><pre><span></span><code>nano data/conf/nginx/site.my_content.custom
+</code></pre></div>
+<p>Dieser Dateiname muss keine ".conf"-Erweiterung haben, sondern folgt dem Muster <code>site.*.custom</code>, wobei <code>*</code> ein eigener Name ist.</p>
+<p>Wenn PHP in eine benutzerdefinierte Site eingebunden werden soll, verwenden Sie bitte den PHP-FPM-Listener auf phpfpm:9002 oder erstellen Sie einen neuen Listener in <code>data/conf/phpfpm/php-fpm.d/pools.conf</code>.</p>

+  <h1>Subdomäne webmail.example.org erstellen</h1>
+
+<p><strong>WICHTIG</strong>: Diese Anleitung gilt nur für Konfigurationen, bei denen SNI nicht aktiviert ist. Wenn SNI aktiviert ist, muss der Zertifikatspfad angepasst werden. Etwas wie <code>ssl_certificate,key /etc/ssl/mail/webmail.example.org/cert.pem,key.pem;</code> wird genügen. <strong>Aber</strong>: Das Zertifikat sollte <strong>zuerst</strong> bezogen werden und erst wenn das Zertifikat existiert, sollte eine Site Config erstellt werden. Nginx wird nicht starten, wenn es das Zertifikat und den Schlüssel nicht finden kann.</p>
+<p>Um eine Subdomain <code>webmail.example.org</code> zu erstellen und sie auf SOGo umzuleiten, müssen Sie eine <strong>neue</strong> Nginx-Site erstellen. Achten Sie dabei auf "CHANGE_TO_MAILCOW_HOSTNAME"!</p>
+<p><strong>nano data/conf/nginx/webmail.conf</strong></p>
+<div class="highlight"><pre><span></span><code>server {
+  ssl_certificate /etc/ssl/mail/cert.pem;
+  ssl_certificate_key /etc/ssl/mail/key.pem;
+  index index.php index.html;
+  client_max_body_size 0;
+  root /web;
+  include /etc/nginx/conf.d/listen_plain.active;
+  include /etc/nginx/conf.d/listen_ssl.active;
+<span class="hll">  server_name webmail.example.org;
+</span>  server_tokens off;
+  location ^~ /.well-known/acme-challenge/ {

+    default_type &quot;text/plain&quot;;
+  }
+
+  location / {
+<span class="hll">    return 301 https://CHANGE_TO_MAILCOW_HOSTNAME/SOGo;
+</span>  }
+}
+</code></pre></div>
+<p>Speichern Sie und starten Sie Nginx neu: <code>docker-compose restart nginx-mailcow</code>.</p>
+<p>Öffnen Sie nun <code>mailcow.conf</code> und suchen Sie <code>ADDITIONAL_SAN</code>.
+Fügen Sie <code>webmail.example.org</code> zu diesem Array hinzu, verwenden Sie keine Anführungszeichen!</p>
+<div class="highlight"><pre><span></span><code>ADDITIONAL_SAN=webmail.example.org
+</code></pre></div>
+<p>Führen Sie <code>docker-compose up -d</code> aus. Siehe "acme-mailcow" und "nginx-mailcow" Logs, wenn etwas fehlschlägt.</p>

+
+<p>Für Transport maps, die nicht in mailcow UI konfiguriert werden, verwenden Sie bitte <code>data/conf/postfix/custom_transport.pcre</code>, um zu verhindern, dass bestehende Maps oder Einstellungen durch Updates überschrieben werden.</p>
+<p>In den meisten Fällen ist die Verwendung dieser Datei <strong>nicht</strong> notwendig. Bitte vergewissern Sie sich, dass mailcow UI nicht in der Lage ist, den gewünschten Datenverkehr richtig zu routen, bevor Sie diese Datei verwenden.</p>
+<p>Die Datei benötigt gültigen PCRE-Inhalt und kann Postfix zerstören, wenn sie falsch konfiguriert ist.</p>

+<p>Diese Option ist keine Best-Practice und sollte nur verwendet werden, wenn es keine andere Möglichkeit gibt, das zu erreichen, was Sie erreichen wollen.</p>
+<p>Erstellen Sie einfach eine Datei <code>data/conf/postfix/check_sasl_access</code> und tragen Sie den folgenden Inhalt ein. Dieser Benutzer muss in Ihrer Installation existieren und muss sich vor dem Versenden von Mails authentifizieren.
+<div class="highlight"><pre><span></span><code>user-to-allow-everything@example.com OK
+</code></pre></div></p>
+<p>Öffnen Sie <code>data/conf/postfix/main.cf</code> und suchen Sie <code>smtpd_sender_restrictions</code>. Fügen Sie <code>check_sasl_access hash:/opt/postfix/conf/check_sasl_access</code> wie folgt ein:
+<div class="highlight"><pre><span></span><code>smtpd_sender_restrictions = check_sasl_access hash:/opt/postfix/conf/check_sasl_access reject_authenticated_sender_login_mismatch [...]
+</code></pre></div></p>
+<p>Postmap auf check_sasl_access ausführen:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec postfix-mailcow postmap /opt/postfix/conf/check_sasl_access
+</code></pre></div>
+<p>Starten Sie den Postfix-Container neu.</p>

+  <h1>Statistik mit pflogsumm</h1>
+
+<p>Um pflogsumm mit dem Standard-Logging-Treiber zu verwenden, müssen wir postfix-mailcow über docker logs abfragen und die Ausgabe zu pflogsumm leiten:</p>
+<div class="highlight"><pre><span></span><code>docker logs --since 24h $(docker ps -qf name=postfix-mailcow) | pflogsumm
+</code></pre></div>
+<p>Die obige Log-Ausgabe ist auf die letzten 24 Stunden beschränkt.</p>
+<p>Es ist auch möglich, einen täglichen pflogsumm-Bericht über cron zu erstellen. Erstellen Sie die Datei /etc/cron.d/pflogsumm mit dem folgenden Inhalt:</p>
+<div class="highlight"><pre><span></span><code>SHELL=/bin/bash
+59 23 * * * root docker logs --since 24h $(docker ps -qf name=postfix-mailcow) | /usr/sbin/pflogsumm -d today | mail -s &quot;Postfix Report of $(date)&quot; postmaster@example.net
+</code></pre></div>
+<p>Basierend auf den Postfix-Logs der letzten 24 Stunden sendet dieses Beispiel jeden Tag um 23:59:00 Uhr einen pflogsumm-Bericht an <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#112;&#111;&#115;&#116;&#109;&#97;&#115;&#116;&#101;&#114;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#110;&#101;&#116;">&#112;&#111;&#115;&#116;&#109;&#97;&#115;&#116;&#101;&#114;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#110;&#101;&#116;</a>.</p>

+  <h1>IP in Postscreen auf die Whitelist setzen</h1>
+
+<p>IPs können in der Datei <code>data/conf/postfix/custom_postscreen_whitelist.cidr</code> aus dem Postscreen und damit <em>auch</em> aus den RBL-Prüfungen entfernt werden.</p>
+<p>Postscreen führt mehrere Prüfungen durch, um bösartige Absender zu identifizieren. In den meisten Fällen möchten Sie eine IP-Adresse auf die Whitelist setzen, um sie von der Suche nach einer schwarzen Liste auszuschließen.</p>
+<p>Das Format der Datei ist wie folgt</p>
+<p><code>CIDR ACTION</code></p>
+<p>Dabei steht CIDR für eine einzelne IP-Adresse oder einen IP-Bereich in CIDR-Notation und action entweder für "permit" oder "reject".</p>
+<p>Beispiel:</p>
+<div class="highlight"><pre><span></span><code># Regeln werden in der angegebenen Reihenfolge ausgewertet.
+# Schwarze Liste 192.168.* außer 192.168.0.1.
+192.168.0.1 permit
+192.168.0.0/16 reject
+</code></pre></div>
+<p>Die Datei wird spontan neu geladen, ein Neustart von Postfix ist nicht erforderlich.</p>

+  <h1>Relayhosts</h1>
+
+<p>Seit dem 12. September 2018 können Sie Relayhosts als Admin über die mailcow UI einrichten.</p>
+<p>Dies ist nützlich, wenn Sie ausgehende E-Mails für eine bestimmte Domain an einen Drittanbieter-Spamfilter oder einen Dienst wie Mailgun oder Sendgrid weiterleiten möchten. Dies ist auch bekannt als ein <em>smarthost</em>.
+Falls nicht, überprüfen Sie den Fehler und beheben Sie ihn.</p>
+<h2 id="einen-neuen-relayhost-hinzufugen">Einen neuen Relayhost hinzufügen<a class="headerlink" href="#einen-neuen-relayhost-hinzufugen" title="Permanent link">&para;</a></h2>
+<p>Gehen Sie auf die Registerkarte "Routing" im Abschnitt "Konfiguration und Details" der mailcow UI.
+Hier sehen Sie eine Liste der derzeit eingerichteten Relayhosts.</p>
+<p>Blättern Sie zum Abschnitt "Absenderabhängigen Transport hinzufügen".</p>
+<p>Fügen Sie unter <code>Host</code> den Host hinzu, an den Sie weiterleiten möchten.<br>
+<em>Beispiel: Wenn Sie Mailgun zum Senden von E-Mails anstelle Ihrer Server-IP verwenden möchten, geben Sie smtp.mailgun.org ein.</em></p>
+<p>Wenn der Relay-Host zur Authentifizierung einen Benutzernamen und ein Passwort benötigt, geben Sie diese in die entsprechenden Felder ein.<br>
+Beachten Sie, dass die Anmeldedaten im Klartext gespeichert werden.</p>
+<h3 id="testen-sie-einen-relayhost">Testen Sie einen Relayhost<a class="headerlink" href="#testen-sie-einen-relayhost" title="Permanent link">&para;</a></h3>
+<p>Um zu testen, ob die Verbindung zum Host funktioniert, klicken Sie in der Liste der Relayhosts auf <code>Test</code> und geben Sie eine <em>Von:</em>-Adresse ein. Führen Sie dann den Test aus.</p>
+<p>Sie sehen dann die Ergebnisse der SMTP-Übertragung. Wenn alles klappt, sollten Sie Folgendes sehen:
+<code>SERVER -&gt; CLIENT: 250 2.0.0 Ok: queued as A093B401D4</code> als eine der letzten Zeilen.</p>
+<p>Ist dies nicht der Fall, überprüfen Sie den angegebenen Fehler und beheben Sie ihn.</p>
+<p><strong>Hinweis:</strong> Einige Hosts, insbesondere solche, die keine Authentifizierung verlangen, verweigern Verbindungen von Servern, die nicht zuvor in ihr System aufgenommen wurden. Lesen Sie unbedingt die Dokumentation des Relayhosts, um sicherzustellen, dass Sie Ihre Domain und/oder die Server-IP zu ihrem System hinzugefügt haben.</p>
+<p><strong>Tipp:</strong> Sie können die standardmäßige <em>Von:</em>-Adresse, die der Test verwendet, von <em>null@mailcow.email</em> auf eine beliebige E-Mail-Adresse ändern, indem Sie die Variable <em>$RELAY_TO</em> in der Datei <em>vars.inc.php</em> unter <em>/opt/mailcow-dockerized/data/web/inc</em> ändern. <br> Auf diese Weise können Sie überprüfen, ob das Relay funktioniert hat, indem Sie das Zielpostfach überprüfen.</p>
+<h2 id="relayhost-fur-eine-domain-festlegen">Relayhost für eine Domain festlegen<a class="headerlink" href="#relayhost-fur-eine-domain-festlegen" title="Permanent link">&para;</a></h2>
+<p>Wechseln Sie auf die Registerkarte "Domains" im Abschnitt "E-Mail-Setup" der mailcow UI.</p>
+<p>Bearbeiten Sie die gewünschte Domain.</p>
+<p>Wählen Sie den neu hinzugefügten Host in der Dropdown-Liste "Absenderabhängige Transporte" aus und speichern Sie die Änderungen.</p>
+<p>Senden Sie eine E-Mail von einer Mailbox auf dieser Domain und Sie sollten in den Protokollen sehen, dass Postfix die Nachricht an den Relayhost weiterleitet.</p>

+  <h1>Vertrauenswürdige Netzwerke hinzufügen</h1>
+
+<p>Standardmäßig betrachtet mailcow <strong>alle Netzwerke als nicht vertrauenswürdig</strong>, ausgenommen seine eigenen IPV4_NETWORK und IPV6_NETWORK Bereiche. Obwohl dies in den meisten Fällen vernünftig ist, kann es Umstände geben, unter denen man diese Einschränkung lockern muss.</p>
+<p>Standardmäßig verwendet mailcow <code>mynetworks_style = subnet</code> um interne Subnetze zu bestimmen und lässt <code>mynetworks</code> unkonfiguriert.</p>
+<p>Wenn Sie sich entscheiden, <code>mynetworks</code> zu setzen, ignoriert Postfix die mynetworks_style Einstellung. Das bedeutet, dass Sie die Bereiche IPV4_NETWORK und IPV6_NETWORK sowie die Loopback-Subnetze manuell hinzufügen müssen!</p>
+<h2 id="unauthentifiziertes-relaying">Unauthentifiziertes Relaying<a class="headerlink" href="#unauthentifiziertes-relaying" title="Permanent link">&para;</a></h2>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Eine falsche Einstellung von <code>mynetworks</code> erlaubt es Ihrem Server, als offenes Relay verwendet zu werden. Wenn dies missbraucht wird, <strong>beeinträchtigt</strong> dies Ihre Fähigkeit, E-Mails zu versenden, und es kann einige Zeit dauern, bis dies behoben ist.</p>
+</div>
+<h3 id="ipv4-hostssubnetze">IPv4-Hosts/Subnetze<a class="headerlink" href="#ipv4-hostssubnetze" title="Permanent link">&para;</a></h3>
+<p>Um das Subnetz <code>192.168.2.0/24</code> zu den vertrauenswürdigen Netzwerken hinzuzufügen, können Sie die folgende Konfiguration verwenden, abhängig von Ihren IPV4_NETWORK und IPV6_NETWORK Bereichen:</p>
+<p>Bearbeiten Sie <code>data/conf/postfix/extra.cf</code>:</p>
+<div class="highlight"><pre><span></span><code>mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 [fe80::]/10 172.22.1.0/24 [fd4d:6169:6c63:6f77::]/64 192.168.2.0/24
+</code></pre></div>
+<p>Führen Sie <code>docker-compose restart postfix-mailcow</code> aus, um Ihre neuen Einstellungen zu übernehmen.</p>
+<h3 id="ipv6-hostssubnets">IPv6-Hosts/Subnets<a class="headerlink" href="#ipv6-hostssubnets" title="Permanent link">&para;</a></h3>
+<p>Das Hinzufügen von IPv6-Hosts erfolgt auf die gleiche Weise wie bei IPv4, allerdings muss das Subnetz in eckige Klammern <code>[]</code> gesetzt und die Netzmaske angehängt werden.</p>
+<p>Um das Subnetz 2001:db8::/32 zu den vertrauenswürdigen Netzwerken hinzuzufügen, können Sie die folgende Konfiguration verwenden, abhängig von Ihren IPV4_NETWORK- und IPV6_NETWORK-Bereichen:</p>
+<p>Bearbeiten Sie <code>data/conf/postfix/extra.cf</code>:</p>
+<div class="highlight"><pre><span></span><code>mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 [fe80::]/10 172.22.1.0/24 [fd4d:6169:6c63:6f77::]/64 [2001:db8::]/32
+</code></pre></div>
+<p>Führen Sie <code>docker-compose restart postfix-mailcow</code> aus, um Ihre neuen Einstellungen zu übernehmen.</p>

+  <h1>Redis</h1>
+
+<p>Redis wird als Key-Value-Speicher für die Einstellungen und Daten von rspamd und (einige von) mailcow verwendet. Wenn Sie mit Redis nicht vertraut sind, lesen Sie bitte die <a href="https://redis.io/topics/introduction">Einführung in Redis</a> und besuchen Sie gegebenenfalls diese <a href="http://try.redis.io/">wunderbare Anleitung</a>, um zu erfahren, wie man Redis benutzt.</p>
+<h2 id="client">Client<a class="headerlink" href="#client" title="Permanent link">&para;</a></h2>
+<p>Um sich mit dem redis cli zu verbinden, führen Sie aus:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec redis-mailcow redis-cli
+</code></pre></div>
+<h3 id="fehlersuche">Fehlersuche<a class="headerlink" href="#fehlersuche" title="Permanent link">&para;</a></h3>
+<p>Hier sind einige nützliche Befehle für den redis-cli zur Fehlersuche:</p>
+<h5 id="monitor">MONITOR<a class="headerlink" href="#monitor" title="Permanent link">&para;</a></h5>
+<p>Überwacht alle vom Server empfangenen Anfragen in Echtzeit:</p>
+<div class="highlight"><pre><span></span><code># docker-compose exec redis-mailcow redis-cli

+<h5 id="ping">PING<a class="headerlink" href="#ping" title="Permanent link">&para;</a></h5>

+  <h1>Rspamd</h1>
+
+<p>Rspamd wird für die AV-Verarbeitung, DKIM-Signierung und SPAM-Verarbeitung verwendet. Es ist ein leistungsfähiges und schnelles Filtersystem. Für eine ausführlichere Dokumentation über Rspamd besuchen Sie bitte die [Rspamd Dokumentation] (<a href="https://rspamd.com/doc/index.html">https://rspamd.com/doc/index.html</a>).</p>
+<h2 id="spam-ham-lernen">Spam &amp; Ham lernen<a class="headerlink" href="#spam-ham-lernen" title="Permanent link">&para;</a></h2>
+<p>Rspamd lernt, ob es sich um Spam oder Ham handelt, wenn Sie eine Nachricht in oder aus dem Junk-Ordner in ein anderes Postfach als den Papierkorb verschieben.
+Dies wird durch die Verwendung des Sieve-Plugins "sieve_imapsieve" und Parser-Skripte erreicht.</p>
+<p>Rspamd liest auch automatisch Mails, wenn eine hohe oder niedrige Punktzahl erkannt wird (siehe <a href="https://rspamd.com/doc/configuration/statistic.html#autolearning">https://rspamd.com/doc/configuration/statistic.html#autolearning</a>). Wir haben das Plugin so konfiguriert, dass es ein vernünftiges Verhältnis zwischen Spam- und Ham-Learnings beibehält.</p>
+<p>Die Bayes-Statistiken werden in Redis als Schlüssel <code>BAYES_HAM</code> und <code>BAYES_SPAM</code> gespeichert.</p>
+<p>Neben Bayes wird ein lokaler Fuzzy-Speicher verwendet, um wiederkehrende Muster in Texten oder Bildern zu lernen, die auf Ham oder Spam hinweisen.</p>
+<p>Sie können auch die Web-UI von Rspamd verwenden, um Ham und/oder Spam zu lernen oder bestimmte Einstellungen von Rspamd anzupassen.</p>
+<h3 id="spam-oder-ham-aus-bestehendem-verzeichnis-lernen">Spam oder Ham aus bestehendem Verzeichnis lernen<a class="headerlink" href="#spam-oder-ham-aus-bestehendem-verzeichnis-lernen" title="Permanent link">&para;</a></h3>
+<p>Sie können einen Einzeiler verwenden, um Mails im Klartextformat (unkomprimiert) zu lernen:</p>
+<div class="highlight"><pre><span></span><code><span class="c1"># Ham</span>
+<span class="k">for</span> file <span class="k">in</span> /my/folder/cur/*<span class="p">;</span> <span class="k">do</span> docker <span class="nb">exec</span> -i <span class="k">$(</span>docker-compose ps -q rspamd-mailcow<span class="k">)</span> rspamc learn_ham &lt; <span class="nv">$file</span><span class="p">;</span> <span class="k">done</span>
+<span class="c1"># Spam</span>
+<span class="k">for</span> file <span class="k">in</span> /my/folder/.Junk/cur/*<span class="p">;</span> <span class="k">do</span> docker <span class="nb">exec</span> -i <span class="k">$(</span>docker-compose ps -q rspamd-mailcow<span class="k">)</span> rspamc learn_spam &lt; <span class="nv">$file</span><span class="p">;</span> <span class="k">done</span>
+</code></pre></div>
+<p>Erwägen Sie, einen lokalen Ordner als neues Volume an <code>rspamd-mailcow</code> in <code>docker-compose.yml</code> anzuhängen und die gegebenen Dateien innerhalb des Containers zu lernen. Dies kann als Workaround verwendet werden, um komprimierte Daten mit zcat zu parsen. Beispiel:</p>
+<p>``bash
+for file in /data/old_mail/.Junk/cur/*; do rspamc learn_spam &lt; zcat $file; done
+<div class="highlight"><pre><span></span><code>### Gelernte Daten zurücksetzen (Bayes, Neural)
+
+Sie müssen die Schlüssel in Redis löschen, um die gelernten Daten zurückzusetzen, also erstellen Sie jetzt eine Kopie Ihrer Redis-Datenbank:

+
+Nur Nachrichten mit einer höheren Punktzahl werden als Greylisting betrachtet (soft rejected). Es ist schlechte Praxis, Greylisting zu deaktivieren.
+
+Sie können Greylisting serverweit durch Editieren deaktivieren:

+
+Fügen Sie die Zeile hinzu:

+<p>Waehrend das oben genannte fuer abgelehnte Mails mit einem hohen Spam-Score funktioniert, ignorieren Prefilter-Aktionen diese Einstellung. Für diese Karten muss das Multimap-Modul in Rspamd angepasst werden:</p>
+<ol>
+<li>
+<p>Finden Sie das Prefilet-Reject-Symbol, für das Sie die Nachricht ändern wollen, führen Sie dazu aus: <code>grep -R "SYMBOL_YOU_WANT_TO_ADJUST" /opt/mailcow-dockerized/data/conf/rspamd/</code></p>
+</li>
+<li>
+<p>Fügen Sie Ihre eigene Nachricht als neue Zeile hinzu:</p>

+<h2 id="whitelist-fur-bestimmte-clamav-signaturen">Whitelist für bestimmte ClamAV-Signaturen<a class="headerlink" href="#whitelist-fur-bestimmte-clamav-signaturen" title="Permanent link">&para;</a></h2>
+<p>Es kann vorkommen, dass legitime (saubere) Mails von ClamAV blockiert werden (Rspamd markiert die Mail mit <code>VIRUS_FOUND</code>). So werden beispielsweise interaktive PDF-Formularanhänge standardmäßig blockiert, da der eingebettete Javascript-Code für schädliche Zwecke verwendet werden könnte. Überprüfen Sie dies anhand der clamd-Protokolle, z.B.:</p>
+<div class="highlight"><pre><span></span><code>docker-compose logs clamd-mailcow <span class="p">|</span> grep <span class="s2">&quot;FOUND&quot;</span>
+</code></pre></div>
+<p>Diese Zeile bestätigt, dass ein solcher identifiziert wurde:</p>
+<div class="highlight"><pre><span></span><code>clamd-mailcow_1 | Sat Sep 28 07:43:24 2019 -&gt; instream(local): PUA.Pdf.Trojan.EmbeddedJavaScript-1(e887d2ac324ce90750768b86b63d0749:363325) FOUND
+</code></pre></div>
+<p>Um diese spezielle Signatur auf die Whitelist zu setzen (und den Versand dieses Dateityps im Anhang zu ermöglichen), fügen Sie sie der ClamAV-Signatur-Whitelist-Datei hinzu:</p>
+<div class="highlight"><pre><span></span><code><span class="nb">echo</span> <span class="s1">&#39;PUA.Pdf.Trojan.EmbeddedJavaScript-1&#39;</span> &gt;&gt; data/conf/clamav/whitelist.ign2
+</code></pre></div>
+<p>Dann starten Sie den clamd-mailcow Service Container in der mailcow UI oder mit docker-compose neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart clamd-mailcow
+</code></pre></div>
+<p>Bereinigen Sie zwischengespeicherte ClamAV-Ergebnisse in Redis:</p>
+<div class="highlight"><pre><span></span><code># docker-compose exec redis-mailcow /bin/sh
+/data # redis-cli KEYS rs_cl* | xargs redis-cli DEL
+/data # exit
+</code></pre></div>
+<h2 id="verwerfen-statt-zuruckweisen">Verwerfen statt zurückweisen<a class="headerlink" href="#verwerfen-statt-zuruckweisen" title="Permanent link">&para;</a></h2>
+<p>Wenn Sie eine Nachricht stillschweigend verwerfen wollen, erstellen oder bearbeiten Sie die Datei <code>data/conf/rspamd/override.d/worker-proxy.custom.inc</code> und fügen Sie den folgenden Inhalt hinzu:</p>
+<div class="highlight"><pre><span></span><code>discard_on_reject = true;
+</code></pre></div>
+<p>Starten Sie Rspamd neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart rspamd-mailcow
+</code></pre></div>
+<h2 id="losche-alle-ratelimit-schlussel">Lösche alle Ratelimit-Schlüssel<a class="headerlink" href="#losche-alle-ratelimit-schlussel" title="Permanent link">&para;</a></h2>
+<p>Wenn Sie das UI nicht verwenden wollen und stattdessen alle Schlüssel in der Redis-Datenbank löschen wollen, können Sie redis-cli für diese Aufgabe verwenden:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec redis-mailcow sh
+# Unlink (verfügbar in Redis &gt;=4.) löscht im Hintergrund
+redis-cli --scan --pattern RL* | xargs redis-cli unlink
+</code></pre></div>
+<p>Starten Sie Rspamd neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose <span class="nb">exec</span> redis-mailcow sh
+</code></pre></div>
+<h2 id="erneutes-senden-von-quarantane-benachrichtigungen-auslosen">Erneutes Senden von Quarantäne-Benachrichtigungen auslösen<a class="headerlink" href="#erneutes-senden-von-quarantane-benachrichtigungen-auslosen" title="Permanent link">&para;</a></h2>
+<p>Sollte nur zur Fehlersuche verwendet werden!</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow bash
+mysql -umailcow -p$DBPASS mailcow -e &quot;update quarantine set notified = 0;&quot;
+redis-cli -h redis DEL Q_LAST_NOTIFIED
+quarantine_notify.py
+</code></pre></div>
+<h2 id="speicherung-der-historie-erhohen">Speicherung der Historie erhöhen<a class="headerlink" href="#speicherung-der-historie-erhohen" title="Permanent link">&para;</a></h2>
+<p>Standardmäßig speichert Rspamd 1000 Elemente in der Historie.</p>
+<p>Die Historie wird komprimiert gespeichert.</p>
+<p>Es wird empfohlen, hier keinen unverhältnismäßig hohen Wert zu verwenden, probieren Sie etwas in der Größenordnung von 5000 oder 10000 und sehen Sie, wie Ihr Server damit umgeht:</p>
+<p>Bearbeiten Sie <code>data/conf/rspamd/local.d/history_redis.conf</code>:</p>
+<div class="highlight"><pre><span></span><code>nrows = 1000; # Ändern Sie diesen Wert
+</code></pre></div>
+<p>Starten Sie anschließend Rspamd neu: <code>docker-compose restart rspamd-mailcow</code></p>

+<p>mailcow-Builds nach dem 28. Januar 2021 können das CSS-Thema von SOGo ändern, indem sie <code>data/conf/sogo/custom-theme.js</code> bearbeiten.
+Bitte schauen Sie sich die AngularJS Material <a href="https://material.angularjs.org/latest/Theming/01_introduction">intro</a> und <a href="https://material.angularjs.org/latest/Theming/03_configuring_a_theme">documentation</a> sowie die <a href="https://material.io/archive/guidelines/style/color.html#color-color-palette">material style guideline</a> an, um zu erfahren, wie das funktioniert. </p>
+<p>Sie können die mitgelieferte <code>custom-theme.js</code> als Beispiel verwenden, indem Sie die Kommentare entfernen.
+Nachdem Sie <code>data/conf/sogo/custom-theme.js</code> modifiziert und Änderungen an Ihrem neuen SOGo-Theme vorgenommen haben, müssen Sie </p>
+<ol>
+<li>Bearbeiten Sie <code>data/conf/sogo/sogo.conf</code> und fügen Sie <code>SOGoUIxDebugEnabled = YES;</code> ein.</li>
+<li>SOGo und Memcached Container neu starten, indem man <code>docker-compose restart memcached-mailcow sogo-mailcow</code> ausführt.</li>
+<li>SOGo im Browser öffnen</li>
+<li>öffnen Sie die Entwicklerkonsole des Browsers, normalerweise ist die Tastenkombination F12</li>
+<li>nur wenn Sie Firefox benutzen: schreiben Sie mit der Hand in die Entwicklerkonsole <code>allow pasting</code> und drücken Sie Enter</li>
+<li>fügen Sie den Java-Script-Schnipsel in die Entwicklungskonsole ein:
+<div class="highlight"><pre><span></span><code>copy([].slice.call(document.styleSheets)

+  .filter(e =&gt; e.hasAttribute(&#39;md-theme-style&#39;))
+  .map(e =&gt; e.textInhalt)
+  .join(&#39;\n&#39;)
+)
+</code></pre></div></li>
+<li>Öffnen Sie den Texteditor und fügen Sie die Daten aus der Zwischenablage ein (Strg+V), Sie sollten ein minimiertes CSS erhalten, speichern Sie es</li>
+<li>kopieren Sie die CSS-Datei auf den Mailcow-Server <code>data/conf/sogo/custom-theme.css</code></li>
+<li>editiere <code>data/conf/sogo/sogo.conf</code> und setze <code>SOGoUIxDebugEnabled = NO;</code></li>

+  <h1>Verwendung eines externen DNS-Dienstes</h1>
+
+<p>Wenn Sie einen externen DNS-Dienst verwenden wollen oder müssen, können Sie entweder einen Forwarder in Unbound einstellen oder eine Override-Datei kopieren, um externe DNS-Server zu definieren:</p>
+<p>!!! warning
+   Bitte verwenden Sie keinen öffentlichen Resolver, wie wir es im obigen Beispiel getan haben. Viele - wenn nicht sogar alle - Blacklist-Lookups werden mit öffentlichen Resolvern fehlschlagen, da der Blacklist-Server Grenzen hat, wie viele Anfragen von einer IP gestellt werden können und öffentliche Resolver diese Grenzen normalerweise erreichen.
+   <strong>Wichtig</strong>: Nur DNSSEC-validierende DNS-Dienste werden funktionieren.</p>
+<h2 id="methode-a-unbound">Methode A, Unbound<a class="headerlink" href="#methode-a-unbound" title="Permanent link">&para;</a></h2>
+<p>Bearbeiten Sie <code>data/conf/unbound/unbound.conf</code> und fügen Sie die folgenden Parameter hinzu:</p>
+<div class="highlight"><pre><span></span><code>forward-zone:
+  name: &quot;.&quot;
+  forward-addr: 8.8.8.8 # VERWENDEN SIE KEINE ÖFFENTLICHEN DNS-SERVER - NUR EIN BEISPIEL
+  forward-addr: 8.8.4.4 # VERWENDET KEINE ÖFFENTLICHEN DNS-SERVER - NUR EIN BEISPIEL
+</code></pre></div>
+<p>Unbound neu starten:</p>

+</code></pre></div>

+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+cp helper-scripts/docker-compose.override.yml.d/EXTERNAL_DNS/docker-compose.override.yml .
+</code></pre></div>
+<p>Bearbeiten Sie <code>docker-compose.override.yml</code> und passen Sie die IP an.</p>

+  <h1>Thresholds</h1>
+
+<p>Watchdog verwendet Standardwerte für alle in <code>docker-compose.yml</code> definierten Thresholde.</p>
+<p>Die Standardwerte sind für die meisten Konfigurationen geeignet.
+Beispiel:
+<div class="highlight"><pre><span></span><code>- NGINX_THRESHOLD=${NGINX_THRESHOLD:-5}
+- UNBOUND_THRESHOLD=${UNBOUND_THRESHOLD:-5}
+- REDIS_THRESHOLD=${REDIS_THRESHOLD:-5}
+- MYSQL_THRESHOLD=${MYSQL_THRESHOLD:-5}
+- MYSQL_REPLICATION_THRESHOLD=${MYSQL_REPLICATION_THRESHOLD:-1}
+- SOGO_THRESHOLD=${SOGO_THRESHOLD:-3}
+- POSTFIX_THRESHOLD=${POSTFIX_THRESHOLD:-8}
+- CLAMD_THRESHOLD=${CLAMD_THRESHOLD:-15}
+- DOVECOT_THRESHOLD=${DOVECOT_THRESHOLD:-12}
+- DOVECOT_REPL_THRESHOLD=${DOVECOT_REPL_THRESHOLD:-20}
+- PHPFPM_THRESHOLD=${PHPFPM_THRESHOLD:-5}
+- RATELIMIT_THRESHOLD=${RATELIMIT_THRESHOLD:-1}
+- FAIL2BAN_THRESHOLD=${FAIL2BAN_THRESHOLD:-1}
+- ACME_THRESHOLD=${ACME_THRESHOLD:-1}
+- RSPAMD_THRESHOLD=${RSPAMD_THRESHOLD:-5}
+- OLEFY_THRESHOLD=${OLEFY_THRESHOLD:-5}
+- MAILQ_THRESHOLD=${MAILQ_THRESHOLD:-20}
+- MAILQ_CRIT=${MAILQ_CRIT:-30}
+</code></pre></div></p>
+<p>Um sie anzupassen, fügen Sie einfach die notwendigen Threshold Variablen (z.B. <code>MAILQ_THRESHOLD=10</code>) zu <code>mailcow.conf</code> hinzu und führen <code>docker-compose up -d</code> aus.</p>

+<p>Das UV-Flag (wie in "user verification") erzwingt, dass WebAuthn den Benutzer verifiziert, bevor es den Zugriff auf den Schlüssel erlaubt (denken Sie an eine PIN). Wir erzwingen keine UV, um Logins über iOS und NFC (YubiKey) zu ermöglichen.</p>
+<h2 id="login-und-schlussel-verarbeitung">Login und Schlüssel-Verarbeitung<a class="headerlink" href="#login-und-schlussel-verarbeitung" title="Permanent link">&para;</a></h2>
+<p>mailcow verwendet <strong>Client-seitige Schlüsselverarbeitung</strong>. Wir bitten den Authentifikator (d.h. YubiKey), die Registrierung in seinem Speicher zu speichern.</p>
+<p>Ein Benutzer muss keinen Benutzernamen eingeben. Die verfügbaren Anmeldedaten - falls vorhanden - werden dem Nutzer angezeigt, wenn er den "Schlüssel-Login" über das Mailcow UI Login auswählt.</p>
+<p>Beim Aufruf des Login-Prozesses werden dem Authentifikator keine Credential-IDs übergeben. Dies wird ihn dazu zwingen, die Anmeldeinformationen in seinem eigenen Speicher zu suchen.</p>
+<h2 id="wer-kann-webauthn-benutzen-um-sich-bei-mailcow-anzumelden">Wer kann WebAuthn benutzen, um sich bei mailcow anzumelden?<a class="headerlink" href="#wer-kann-webauthn-benutzen-um-sich-bei-mailcow-anzumelden" title="Permanent link">&para;</a></h2>
+<p>Ab heute sind nur Administratoren und Domain-Administratoren in der Lage, WebAuthn/FIDO2 einzurichten.</p>
+<hr />

+<p>Pushover macht es einfach, Echtzeit-Benachrichtigungen auf Ihrem Android, iPhone, iPad und Desktop zu erhalten</p>
+</div>
+<p>Sie können Pushover verwenden, um eine Push-Benachrichtigung über jede E-Mail zu erhalten, die Sie für jede Mailbox erhalten, in der Sie diese Funktion aktiviert haben.</p>
+<p>1. Öffnen Sie als Administrator die Einstellungen Ihres Postfachs und scrollen Sie nach unten zu den Pushover-Einstellungen</p>
+<p>2. Registrieren Sie sich bei <a href="https://pushover.net">Pushover</a></p>
+<p>3. Geben Sie Ihren "Benutzerschlüssel" in das Feld "Benutzer-/Gruppenschlüssel" in den Einstellungen Ihres Postfachs ein</p>
+<p>4. Erstellen Sie eine Anwendung, um das API-Token/den API-Schlüssel zu erhalten, das/den Sie ebenfalls in Ihre Postfacheinstellungen eintragen müssen.</p>
+<p>5. Optional können Sie den Titel/Text der Benachrichtigung bearbeiten und bestimmte Absender-E-Mail-Adressen festlegen, bei denen eine Push-Benachrichtigung ausgelöst wird</p>
+<p>6. Speichern Sie alles und überprüfen Sie dann Ihre Anmeldedaten.</p>
+<p>Wenn alles erledigt ist, können Sie testen, ob Sie eine E-Mail senden können, und Sie erhalten eine Push-Nachricht auf Ihrem Telefon</p>

+
+<p>Diese temporären E-Mail-Aliasnamen werden meist dort verwendet, wo wir eine E-Mail-Adresse angeben müssen, aber keine weitere E-Mails wünschen. Sie werden auch Spam-Alias genannt.</p>
+<p>Um ein temporäres E-Mail-Alias zu erstellen, zu löschen oder zu erweitern, müssen Sie sich in mailcow's UI als Mailbox-Nutzer anmelden und zum Reiter <strong>Temporäre E-Mail-Aliase</strong> navigieren:</p>

+  <h1>Zwei-Faktoren-Authentifizierung</h1>
+
+<p>Bislang sind drei Methoden für die <em>Zwei-Faktor-Authentifizierung</em> implementiert: WebAuthn (ersetzt seit Februar 2022 U2F), Yubi OTP und TOTP</p>
+<ul>
+<li>Damit WebAuthn funktioniert, benötigen Sie eine verschlüsselte Verbindung zum Server (HTTPS) sowie einen FIDO-Sicherheitsschlüssel.</li>
+<li>Sowohl WebAuthn als auch Yubi OTP funktionieren gut mit dem fantastischen <a href="https://www.yubico.com">Yubikey</a>.</li>
+<li>Während Yubi OTP eine aktive Internetverbindung und eine API ID + Schlüssel benötigt, funktioniert WebAuthn mit jedem Fido Security Key, kann aber nur verwendet werden, wenn der Zugriff auf mailcow über HTTPS erfolgt.</li>
+<li>WebAuthn und Yubi OTP unterstützen mehrere Schlüssel pro Nutzer.</li>
+<li>Als dritte TFA-Methode verwendet mailcow TOTP: zeitbasierte Einmal-Passwörter. Diese Passwörter können mit Apps wie "Google Authenticator" generiert werden, nachdem zunächst ein QR-Code gescannt oder das gegebene Geheimnis manuell eingegeben wurde.</li>
+</ul>
+<p>Als Administrator können Sie den TFA-Login eines Domain-Administrators vorübergehend deaktivieren, bis dieser sich erfolgreich eingeloggt hat.</p>
+<p>Der für die Anmeldung verwendete Schlüssel wird in grüner Farbe angezeigt, während andere Schlüssel grau bleiben.</p>
+<p>Informationen zum Entfernen von 2FA finden Sie <a href="../../../troubleshooting/debug-reset_pw/#zwei-faktor-authentifizierung-entfernen">hier</a>.</p>
+<h2 id="yubi-otp">Yubi OTP<a class="headerlink" href="#yubi-otp" title="Permanent link">&para;</a></h2>
+<p>Die Yubi API ID und der Schlüssel werden mit der Yubico Cloud API abgeglichen. Bei der Einrichtung von TFA werden Sie nach Ihrem persönlichen API-Konto für diesen Schlüssel gefragt.
+Die API-ID, der API-Schlüssel und die ersten 12 Zeichen (Ihre YubiKeys ID in modhex) werden in der MySQL-Tabelle als Geheimnis gespeichert.</p>
+<h3 id="beispiel-einrichtung">Beispiel-Einrichtung<a class="headerlink" href="#beispiel-einrichtung" title="Permanent link">&para;</a></h3>
+<p>Als erstes muss der YubiKey für die Verwendung als OTP-Generator konfiguriert werden. Laden Sie dazu den <code>YubiKey Manager</code> von der Yubico Website herunter: <a href="https://www.yubico.com/support/download/">hier</a></p>
+<p>Im Folgenden konfigurieren Sie den YubiKey für OTP.
+Über den Menüpunkt <code>Anwendungen</code> -&gt; <code>OTP</code> und einem Klick auf den <code>Konfigurieren</code> Button. Wählen Sie im folgenden Menü <code>Credential Type</code> -&gt; <code>Yubico OTP</code> und klicken Sie auf <code>Next</code>.</p>
+<p>Setzen Sie ein Häkchen in die Checkbox <code>Use serial</code>, generieren Sie eine <code>Private ID</code> und einen <code>Secret key</code> über die Schaltflächen. 
+Damit der YubiKey später validiert werden kann, muss auch das Häkchen in der <code>Upload</code> Checkbox gesetzt werden und klicken Sie dann auf <code>Finish</code>.</p>
+<p>Nun öffnet sich ein neues Browserfenster, in dem Sie unten im Formular ein OTP Ihres YubiKey eingeben müssen (auf das Feld klicken und dann auf Ihren YubiKey tippen). Bestätigen Sie das Captcha und laden Sie die Daten auf den Yubico-Server hoch, indem Sie auf 'Hochladen' klicken. Die Verarbeitung der Daten wird einen Moment dauern.</p>
+<p>Nachdem die Generierung erfolgreich war, werden Ihnen eine <code>Client ID</code> und ein <code>Secret key</code> angezeigt, notieren Sie sich diese Informationen an einem sicheren Ort.</p>
+<p>Nun können Sie <code>Yubico OTP-Authentifizierung</code> aus dem Dropdown-Menü in der mailcow UI auf der Startseite unter <code>Zugang</code> -&gt; <code>Zwei-Faktor-Authentifizierung</code> auswählen. 
+In dem sich nun öffnenden Dialog können Sie einen Namen für diesen YubiKey eingeben und die zuvor notierte <code>Client ID</code> sowie den <code>Secret key</code> in die vorgesehenen Felder eintragen.
+Geben Sie schließlich Ihr aktuelles Kontopasswort ein und berühren Sie nach Auswahl des Feldes <code>Touch Yubikey</code> die Schaltfläche Ihres YubiKey.</p>
+<p>Herzlichen Glückwunsch! Sie können sich nun mit Ihrem YubiKey in die mailcow UI einloggen!</p>

+<p class="admonition-title">Warning</p>
+<p><strong>Seit Februar 2022 hat Google Chrome die Unterstützung für U2F aufgegeben und die Verwendung von WebAuthn standardisiert.<br></strong>
+<em>Die WebAuthn API (der Ersatz für U2F) ist seit dem 21. Januar 2022 Teil von mailcow, wenn Sie also den Key über Februar 2022 hinaus nutzen wollen, sollten Sie ein Update mit der <code>update.sh</code></em> in Betracht ziehen. </p>

+<p>Um WebAuthn zu nutzen, muss der Browser diesen Standard unterstützen:</p>

+<li>Edge (&gt;=18)</li>

+<li>Chrome (&gt;=67)</li>
+<li>Safari (&gt;=13)</li>

+<p>WebAuthn funktioniert auch ohne Internetverbindung.</p>

+<p>Mit dem neuen U2F-Ersatz (WebAuthn) müssen Sie Ihren Fido Security Key neu registrieren, zum Glück ist WebAuthn abwärtskompatibel und unterstützt das U2F-Protokoll.</p>
+</div>
+<p>Im Idealfall sollten Sie beim nächsten Einloggen (mit dem Schlüssel) ein Textfeld erhalten, das besagt, dass Ihr Fido Security Key aufgrund des Updates auf WebAuthn entfernt und als 2-Faktor-Authentifikator gelöscht wurde.</p>
+<p>Aber keine Sorge! Sie können Ihren bestehenden Schlüssel einfach neu registrieren und ihn wie gewohnt verwenden. Sie werden wahrscheinlich nicht einmal einen Unterschied bemerken, außer dass Ihr Browser die U2F-Deaktivierungsmeldung nicht mehr anzeigt.</p>
+<h3 id="deaktivieren-inoffizieller-unterstutzter-fido-security-keys">Deaktivieren inoffizieller unterstützter Fido Security Keys<a class="headerlink" href="#deaktivieren-inoffizieller-unterstutzter-fido-security-keys" title="Permanent link">&para;</a></h3>
+<p>Mit WebAuthn gibt es die Möglichkeit, nur offizielle Fido Security Keys zu verwenden (von den großen Marken wie: Yubico, Apple, Nitro, Google, Huawei, Microsoft, usw.) zu verwenden.</p>
+<p>Dies dient in erster Linie der Sicherheit, da es Administratoren ermöglicht, sicherzustellen, dass nur offizielle Hardware in ihrer Umgebung verwendet werden kann.</p>
+<p>Um diese Funktion zu aktivieren, ändern Sie den Wert <code>WEBAUTHN_ONLY_TRUSTED_VENDORS</code> in mailcow.conf von <code>n</code> auf <code>y</code> und starten Sie die betroffenen Container mit <code>docker-compose up -d</code> neu.</p>
+<p>Die mailcow wird nun die Vendor-Zertifikate verwenden, die sich in Ihrem mailcow-Verzeichnis unter <code>data/web/inc/lib/WebAuthn/rootCertificates</code> befinden. </p>
+<h5 id="beispiel">Beispiel:<a class="headerlink" href="#beispiel" title="Permanent link">&para;</a></h5>
+<p>Wenn Sie die offiziellen Hersteller-Geräte nur auf Apple beschränken wollen, brauchen Sie nur das Apple Hersteller-Zertifikat im <code>data/web/inc/lib/WebAuthn/rootCertificates</code>.
+Nachdem Sie alle anderen Zertifikate gelöscht haben, können Sie WebAuthn 2FA nur noch mit Apple-Geräten aktivieren.</p>
+<p>Das ist für jeden Hersteller gleich, also wählen Sie aus, was Ihnen gefällt (wenn Sie es wollen).</p>
+<h4 id="eigene-zertifikate-fur-webauthn-verwenden">Eigene Zertifikate für WebAuthn verwenden<a class="headerlink" href="#eigene-zertifikate-fur-webauthn-verwenden" title="Permanent link">&para;</a></h4>
+<p>Wenn du ein gültiges Zertifikat vom Hersteller deines Schlüssels hast, kannst du es auch zu deiner Mailcow hinzufügen!</p>
+<p>Kopieren Sie einfach das Zertifikat in den <code>data/web/inc/lib/WebAuthn/rootCertificates</code> Ordner und starten Sie Ihre Mailcow neu.</p>
+<p>Nun sollten Sie in der Lage sein, auch dieses Gerät zu registrieren, obwohl die Überprüfung für die Herstellerzertifikate aktiviert ist, da Sie das Zertifikat manuell hinzugefügt haben. </p>
+<h4 id="ist-es-gefahrlich-den-vendor-check-deaktiviert-zu-lassen">Ist es gefährlich, den Vendor Check deaktiviert zu lassen?<a class="headerlink" href="#ist-es-gefahrlich-den-vendor-check-deaktiviert-zu-lassen" title="Permanent link">&para;</a></h4>
+<p>Nein, das ist es nicht!
+Diese Herstellerzertifikate werden nur zur Überprüfung der Originalhardware verwendet, nicht zur Absicherung des Registrierungsprozesses.</p>
+<p>Wie Sie in diesen Artikeln lesen können, hat die Deaktivierung nichts mit der Software-Sicherheit zu tun:

+<p>Letztendlich ist es aber natürlich Ihre Entscheidung, ob Sie dieses Häkchen deaktiviert oder aktiviert lassen. </p>
+<hr />
+<h2 id="totp">TOTP<a class="headerlink" href="#totp" title="Permanent link">&para;</a></h2>
+<p>Die bekannteste TFA-Methode, die meist mit einem Smartphone verwendet wird.</p>
+<p>Um die TOTP-Methode einzurichten, loggen Sie sich in die Admin UI ein und wählen Sie <code>Time-based OTP (TOTP)</code> aus der Liste.</p>
+<p>Nun öffnet sich ein Modal, in dem Sie einen Namen für Ihr 2FA-"Gerät" (Beispiel: John Deer's Smartphone) und das Passwort des betroffenen Admin-Kontos (mit dem Sie derzeit eingeloggt sind) eingeben müssen.</p>
+<p>Sie haben zwei verschiedene Methoden, um TOTP für Ihr Konto zu registrieren:
+1. Scannen Sie den QR-Code mit Ihrer Authenticator App auf einem Smartphone oder Tablet.
+2. Verwenden Sie den TOTP-Code (unter dem QR-Code) in Ihrem TOTP-Programm oder Ihrer App (wenn Sie keinen QR-Code scannen können).</p>
+<p>Nachdem Sie den QR- oder TOTP-Code in der TOTP-App/dem TOTP-Programm Ihrer Wahl registriert haben, müssen Sie nur noch den nun generierten TOTP-Token (in der App/dem Programm) als Bestätigung in der mailcow UI eingeben, um die TOTP 2FA endgültig zu aktivieren, ansonsten wird sie nicht aktiviert, obwohl der TOTP-Token bereits in Ihrer App/ Ihrem Programm generiert wurde.</p>

+  <h1>HTTP auf HTTPS umleiten</h1>
+
+<p>Seit dem 28. Februar 2017 wird mailcow mit aktivierten Ports 80 und 443 geliefert.</p>
+<p><strong>Verwenden Sie die untenstehende Konfiguration nicht für Reverse-Proxy-Setups</strong>, bitte lesen Sie dazu unsere <a href="../../post_installation/firststeps-rp/">Reverse-Proxy-Anleitung</a>, die einen Redirect von HTTP zu HTTPS beinhaltet.</p>
+<p>Öffne <code>mailcow.conf</code> und setze <code>HTTP_BIND=</code> - falls nicht bereits gesetzt.</p>
+<p>Erstellen Sie eine neue Datei <code>data/conf/nginx/redirect.conf</code> und fügen Sie die folgende Serverkonfiguration in die Datei ein:</p>
+<div class="highlight"><pre><span></span><code>server {
+  root /web;
+  listen 80 default_server;
+  listen [::]:80 default_server;
+  include /etc/nginx/conf.d/server_name.active;
+  if ( $request_uri ~* &quot;%0A|%0D&quot; ) { return 403; }
+  location ^~ /.well-known/acme-challenge/ {
+    allow all;
+    default_type &quot;text/plain&quot;;
+  }
+  location / {
+    return 301 https://$host$uri$is_args$args;
+  }
+}
+</code></pre></div>
+<p>Falls Sie den Parameter HTTP_BIND geändert haben, erstellen Sie den Container neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div>
+<p>Andernfalls starten Sie Nginx neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart nginx-mailcow
+</code></pre></div>

+<p><strong>Sie brauchen diese Datei nicht zu ändern oder zu erstellen, autodiscover funktioniert sofort</strong>. Diese Anleitung ist nur für Anpassungen des Autodiscover- oder Autokonfigurationsprozesses gedacht.</p>
+<p>Neuere Outlook-Clients (insbesondere solche, die mit O365 ausgeliefert werden) führen keine automatische Erkennung von E-Mail-Profilen durch.
+Denken Sie daran, dass <strong>ActiveSync NICHT mit einem Desktop-Client</strong> verwendet werden sollte.</p>
+<p>Öffnen/erstellen Sie <code>data/web/inc/vars.local.inc.php</code> und fügen Sie Ihre Änderungen in das Konfigurationsfeld ein.</p>
+<p>Die Änderungen werden mit "$autodiscover_config" in <code>data/web/inc/vars.inc.php</code> zusammengeführt):</p>

+  <h1>TLS 1.0 und TLS 1.1 wieder aktivieren</h1>
+
+<p>Am 12. Februar 2020 haben wir die veralteten Protokolle TLS 1.0 und 1.1 in Dovecot (POP3, POP3S, IMAP, IMAPS) und Postfix (SMTPS, SUBMISSION) deaktiviert.</p>
+<p>Unauthentifizierte Mails über SMTP an Port 25/tcp akzeptieren weiterhin &gt;= TLS 1.0 . Es ist besser, eine schwache Verschlüsselung zu akzeptieren als gar keine.</p>
+<p><strong>Wie kann man schwache Protokolle wieder aktivieren?</strong></p>
+<p>Bearbeiten Sie <code>data/conf/postfix/extra.cf</code>:</p>
+<div class="highlight"><pre><span></span><code>submission_smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
+smtps_smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
+</code></pre></div>
+<p>Bearbeiten Sie <code>data/conf/dovecot/extra.conf</code>:</p>
+<div class="highlight"><pre><span></span><code>ssl_min_protocol = TLSv1
+</code></pre></div>
+<p>Starten Sie die betroffenen Dienste neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart postfix-mailcow dovecot-mailcow
+</code></pre></div>
+<p>Tipp: Sie können TLS 1.2 in Windows 7 aktivieren.</p>

+  <h1>Skripte vor und nach Aktualisierungen ausführen</h1>
+
+<p>Es ist möglich, Pre- und Post-Update-Hooks zum <code>update.sh</code> Skript hinzuzufügen, das Ihre gesamte mailcow-Installation aktualisiert.</p>
+<p>Um dies zu tun, fügen Sie einfach das entsprechende Bash-Skript in Ihr Mailcow-Root-Verzeichnis ein:  </p>
+<ul>
+<li><code>pre_update_hook.sh</code> für Befehle, die vor dem Update laufen sollen</li>
+<li><code>post_update_hook.sh</code> für Befehle, die nach dem Update ausgeführt werden sollen</li>
+</ul>
+<p>Beachten Sie, dass <code>pre_update_hook.sh</code> jedes Mal ausgeführt wird, wenn Sie <code>update.sh</code> aufrufen, und <code>post_update_hook.sh</code> wird nur ausgeführt, wenn die Aktualisierung erfolgreich war und das Skript nicht erneut ausgeführt werden muss.</p>
+<p>Die Skripte werden von der Bash ausgeführt, ein Interpreter (z.B. <code>#!/bin/bash</code>) sowie ein Execute Permission Flag ("+x") sind nicht erforderlich.</p>

+Das ist eine sehr schlechte Idee, wenn es darum geht, Spam mit DNS-basierten Blackhole-Listen (DNSBL) oder ähnlichen Techniken zu filtern.
+Die meisten, wenn nicht alle Anbieter wenden eine Ratenbegrenzung an, die auf dem DNS-Resolver basiert, der für die Abfrage ihres Dienstes verwendet wird.
+Wenn Sie einen öffentlichen Resolver wie Google 4x8, OpenDNS oder einen anderen gemeinsam genutzten DNS-Resolver wie den Ihres Internetanbieters verwenden, werden Sie diese Grenze sehr bald erreichen.</p>

+  <h1>ACL</h1>
+
+<p>Die Bearbeitung eines Domänenadministrators oder eines Mailboxbenutzers ermöglicht es, Einschränkungen für dieses Konto festzulegen.</p>
+<p><strong>Wichtig</strong>: Bei sich überschneidenden Modulen wie Synchronisierungsaufträgen, auf die sowohl Domänenadministratoren als auch Mailbox-Benutzer Zugriff erhalten können, werden die Rechte des Domänenadministrators geerbt, wenn man sich als Mailbox-Benutzer anmeldet.</p>
+<p>Einige Beispiele:</p>
+<p>1.</p>
+<ul>
+<li>Ein Domänenadministrator hat <strong>keinen</strong> Zugriff auf Synchronisierungsaufträge, kann sich aber als Mailbox-Benutzer anmelden</li>
+<li>Wenn er sich als Mailbox-Benutzer anmeldet, erhält er keinen Zugriff auf Synchronisierungsaufträge, auch wenn der betreffende Mailbox-Benutzer bei der direkten Anmeldung Zugriff <em>hat</em>.</li>
+</ul>
+<p>2.</p>
+<ul>
+<li>Ein Domänenadministrator <strong>hat</strong> Zugriff auf Synchronisierungsaufträge und kann sich als Postfachbenutzer anmelden</li>
+<li>Der Mailbox-Benutzer, als der er sich anzumelden versucht, hat <strong>keinen</strong> Zugang zu Synchronisierungsaufträgen</li>
+<li>Der Domänenadministrator, der nun als Mailbox-Benutzer angemeldet ist, erbt die Berechtigung des Mailbox-Benutzers und kann auf Synchronisierungsaufträge zugreifen.</li>
+</ul>
+<p>3.</p>
+<ul>
+<li>Ein Domänenadministrator meldet sich als Mailbox-Benutzer an</li>
+<li>Jede Berechtigung, die <strong>nicht</strong> in der ACL eines Domänenadministrators vorhanden ist, wird automatisch gewährt (Beispiel: zeitlich begrenzter Alias, TLS-Richtlinie usw.)</li>
+</ul>

+<p>Die aktuellste Version von mailcow unterstützt die folgenden Hashing-Methoden vollständig.
+Die Standard-Hashing-Methode ist fett geschrieben:</p>
+<ul>
+<li><strong>BLF-CRYPT</strong></li>
+<li>SSHA</li>
+<li>SSHA256</li>
+<li>SSHA512</li>
+</ul>
+<p>Die obigen Methoden können in <code>mailcow.conf</code> als <code>MAILCOW_PASS_SCHEME</code> Wert verwendet werden.</p>
+<h2 id="nur-lese-hashing-methoden">Nur-Lese-Hashing-Methoden<a class="headerlink" href="#nur-lese-hashing-methoden" title="Permanent link">&para;</a></h2>
+<p>Die folgenden Methoden werden <strong>nur lesend</strong> unterstützt.
+Wenn Sie planen, SOGo zu benutzen (wie standardmäßig), benötigen Sie eine SOGo-kompatible Hash-Methode. Bitte beachten Sie den Hinweis am Ende dieser Seite, wie Sie die Ansicht bei Bedarf aktualisieren können.
+Wenn SOGo deaktiviert ist, können alle unten aufgeführten Hashing-Methoden von mailcow und Dovecot gelesen werden.</p>
+<ul>
+<li>ARGON2I (SOGo kompatibel)</li>
+<li>ARGON2ID (SOGo kompatibel)</li>
+<li>CLEAR</li>
+<li>CLEARTEXT</li>
+<li>CRYPT (SOGo-kompatibel)</li>
+<li>DES-CRYPT</li>
+<li>LDAP-MD5 (SOGo-kompatibel)</li>
+<li>MD5 (SOGo-kompatibel)</li>
+<li>MD5-CRYPT (SOGo-kompatibel)</li>
+<li>PBKDF2 (SOGo-kompatibel)</li>
+<li>PLAIN (SOGo-kompatibel)</li>
+<li>PLAIN-MD4</li>
+<li>PLAIN-MD5</li>
+<li>PLAIN-TRUNC</li>
+<li>SHA (SOGo-kompatibel)</li>

+<li>SHA512-CRYPT (SOGo-kompatibel)</li>
+<li>SMD5 (SOGo kompatibel)</li>
+</ul>
+<p>Das bedeutet, mailcow ist in der Lage, Nutzer mit einem Hash wie <code>{MD5}1a1dc91c907325c69271ddf0c944bc72</code> aus der Datenbank zu verifizieren.</p>
+<p>Der Wert von <code>MAILCOW_PASS_SCHEME</code> wird <em>immer</em> verwendet, um neue Passwörter zu verschlüsseln.</p>
+<hr />
+<blockquote>
+<p>Ich habe die Passwort-Hashes in der SQL-Tabelle "Mailbox" geändert und kann mich nicht anmelden.</p>
+</blockquote>
+<p>Eine "Ansicht" muss aktualisiert werden. Sie können dies durch einen Neustart von sogo-mailcow auslösen: <code>docker-compose restart sogo-mailcow</code></p>

+  <h1>Sender- und Empfängermodell</h1>
+
+<p>Wenn eine Mailbox erstellt wird, kann ein Benutzer Mails von seiner eigenen Mailboxadresse senden und empfangen.</p>
+<pre><code>Die Mailbox me@example.org wird erstellt. example.org ist eine primäre Domäne.
+Hinweis: Eine Mailbox kann nicht in einer Alias-Domäne erstellt werden.
+
+me@example.org ist nur als me@example.org bekannt.
+me@example.org darf als me@example.org senden.
+</code></pre>
+<p>Wir können eine Alias-Domäne für example.org hinzufügen:</p>
+<pre><code>Die Alias-Domäne alias.com wird hinzugefügt und der primären Domäne example.org zugewiesen.
+me@example.org ist nun als me@example.org und me@alias.com bekannt.
+me@example.org darf nun als me@example.org und me@alias.com senden.
+</code></pre>
+<p>Wir können Aliase für eine Mailbox hinzufügen, um Mails von dieser neuen Adresse zu empfangen und zu senden.</p>
+<p>Es ist wichtig zu wissen, dass Sie nicht in der Lage sind, Mails für <code>my-alias@my-alias-domain.tld</code> zu empfangen. Sie müssen diesen speziellen Alias erstellen.</p>
+<pre><code>me@example.org wird der Alias alias@example.org zugewiesen.
+me@example.org ist jetzt bekannt als me@example.org, me@alias.com, alias@example.org
+
+me@example.org ist NICHT als alias@alias.com bekannt.
+</code></pre>
+<p>Bitte beachten Sie, dass dies nicht für "catch-all"-Aliasnamen gilt:</p>
+<pre><code>Die Alias-Domäne alias.com wird hinzugefügt und der primären Domäne example.org zugewiesen
+me@example.org wird der Catch-all-Alias @example.org zugewiesen
+me@example.org ist weiterhin nur als me@example.org bekannt, was die einzige verfügbare send-as Option ist.
+
+Jede an alias.com gesendete E-Mail wird mit dem Catch-All-Alias für example.org übereinstimmen.
+</code></pre>
+<p>Administratoren und Domänenadministratoren können Postfächer bearbeiten, um bestimmten Benutzern zu erlauben, als andere Postfachbenutzer zu senden (sie zu "delegieren").</p>
+<p>Sie können zwischen Mailbox-Benutzern wählen oder die Absenderprüfung für Domänen komplett deaktivieren.</p>
+<h3 id="sogo-mail-von-adressen">SOGo "Mail von"-Adressen<a class="headerlink" href="#sogo-mail-von-adressen" title="Permanent link">&para;</a></h3>
+<p>Mailbox-Benutzer können natürlich ihre eigene Mailbox-Adresse auswählen, sowie alle Alias-Adressen und Aliase, die über Alias-Domänen existieren.</p>
+<p>Wenn Sie einen anderen <em>existierenden</em> Mailbox-Benutzer als Ihre "Mail von"-Adresse auswählen wollen, muss dieser Benutzer Ihnen den Zugriff über SOGo delegieren (siehe SOGo-Dokumentation). Außerdem muss ein mailcow (Domain) Administrator
+Ihnen den Zugang wie oben beschrieben gewähren.</p>

+  <h1>IPv6 deaktivieren</h1>
+
+<p>Dies wird <strong>NUR</strong> empfohlen, wenn Sie kein IPv6-fähiges Netzwerk auf Ihrem Host haben!</p>
+<p>Wenn Sie es wirklich brauchen, können Sie die Verwendung von IPv6 in der Compose-Datei deaktivieren.
+Zusätzlich können Sie auch den Start des Containers "ipv6nat-mailcow" deaktivieren, da er nicht benötigt wird, wenn Sie IPv6 nicht verwenden.</p>
+<p>Anstatt die Datei docker-compose.yml direkt zu bearbeiten, ist es besser, eine Override-Datei zu erstellen 
+zu erstellen und Ihre Änderungen am Dienst dort zu implementieren. Leider scheint dies im Moment nur für Dienste zu funktionieren, nicht für Netzwerkeinstellungen.</p>
+<p>Um IPv6 im mailcow-Netzwerk zu deaktivieren, öffnen Sie docker-compose.yml mit Ihrem bevorzugten Texteditor und suchen Sie nach dem Netzwerk-Abschnitt (er befindet sich am Ende der Datei). </p>
+<p><strong>1.</strong> Ändern Sie docker-compose.yml</p>
+<p>Ändern Sie <code>enable_ipv6: true</code> in <code>enable_ipv6: false</code>:</p>
+<div class="highlight"><pre><span></span><code>networks:
+  mailcow-network:
+    [...]
+    enable_ipv6: true # &lt;&lt;&lt; auf false setzen
+    [...]
+</code></pre></div>
+<p><strong>2.</strong> ipv6nat-mailcow deaktivieren</p>
+<p>Um den ipv6nat-mailcow Container ebenfalls zu deaktivieren, gehen Sie in Ihr mailcow Verzeichnis und erstellen Sie eine neue Datei namens "docker-compose.override.yml": </p>
+<p><strong>HINWEIS:</strong> Wenn Sie bereits eine Override-Datei haben, erstellen Sie diese natürlich nicht neu, sondern fügen Sie die untenstehenden Zeilen entsprechend in Ihre bestehende Datei ein!</p>
+<div class="highlight"><pre><span></span><code># cd /opt/mailcow-dockerized
+# touch docker-compose.override.yml
+</code></pre></div>
+<p>Öffnen Sie die Datei in Ihrem bevorzugten Texteditor und tragen Sie folgendes ein:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+    ipv6nat-mailcow:
+      image: bash:latest
+      neustart: &quot;no&quot;
+      entrypoint: [&quot;echo&quot;, &quot;ipv6nat disabled in compose.override.yml&quot;]
+</code></pre></div>
+<p>Damit diese Änderungen wirksam werden, müssen Sie den Stack vollständig stoppen und dann neu starten, damit Container und Netzwerke neu erstellt werden:</p>
+<div class="highlight"><pre><span></span><code>docker-compose down
+docker-compose up -d
+</code></pre></div>
+<p><strong>3.</strong> Deaktivieren Sie IPv6 in unbound-mailcow</p>
+<p>Bearbeiten Sie <code>data/conf/unbound/unbound.conf</code> und setzen Sie <code>do-ip6</code> auf "no":</p>
+<div class="highlight"><pre><span></span><code>Server:
+  [...]
+  do-ip6: no
+  [...]
+</code></pre></div>
+<p>unbound neu starten:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart unbound-mailcow
+</code></pre></div>
+<p><strong>4.</strong> Deaktivieren Sie IPv6 in postfix-mailcow</p>
+<p>Erstellen Sie <code>data/conf/postfix/extra.cf</code> und setzen Sie <code>smtp_address_preference</code> auf <code>ipv4</code>:</p>
+<div class="highlight"><pre><span></span><code>smtp_address_preference = ipv4
+inet_protocols = ipv4
+</code></pre></div>
+<p>Starten Sie Postfix neu:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart postfix-mailcow
+</code></pre></div>

+  <h1>DMARC Reporting</h1>
+
+<p>Die DMARC-Berichterstattung erfolgt über das Rspamd DMARC-Modul.</p>
+<p>Die Rspamd-Dokumentation finden Sie hier: <a href="https://rspamd.com/doc/modules/dmarc.html">https://rspamd.com/doc/modules/dmarc.html</a></p>
+<p><strong>Wichtig:</strong></p>
+<ol>
+<li>
+<p>Ändern Sie <code>example.com</code>, <code>mail.example.com</code> und <code>Example</code> so, dass sie Ihrer Einrichtung entsprechen</p>
+</li>
+<li>
+<p>Die DMARC-Berichterstattung erfordert zusätzliche Aufmerksamkeit, insbesondere in den ersten Tagen</p>
+</li>
+<li>
+<p>Alle empfangenden Domains, die auf mailcow gehostet werden, senden von einer Reporting-Domain. Es wird empfohlen, die übergeordnete Domain Ihres <code>MAILCOW_HOSTNAME</code> zu verwenden:</p>
+<ul>
+<li>Wenn Ihr <code>MAILCOW_HOSTNAME</code> <code>mail.example.com</code> ist, ändern Sie die folgende Konfiguration in <code>domain = "example.com";</code></li>
+<li>Setzen Sie <code>email</code> gleich, z.B. <code>email = "noreply-dmarc@example.com";</code></li>
+</ul>
+</li>
+<li>
+<p>Es ist optional, aber empfohlen, einen E-Mail-Benutzer <code>noreply-dmarc</code> in mailcow zu erstellen, um Bounces zu behandeln.</p>
+</li>
+</ol>
+<h2 id="aktivieren-sie-dmarc-berichterstattung">Aktivieren Sie DMARC-Berichterstattung<a class="headerlink" href="#aktivieren-sie-dmarc-berichterstattung" title="Permanent link">&para;</a></h2>
+<p>Erstellen Sie die Datei <code>data/conf/rspamd/local.d/dmarc.conf</code> und setzen Sie den folgenden Inhalt:</p>
+<div class="highlight"><pre><span></span><code>reporting {
+    enabled = true;
+    email = &#39;noreply-dmarc@example.com&#39;;
+    domain = &#39;example.com&#39;;
+    org_name = &#39;Example&#39;;
+    helo = &#39;rspamd&#39;;
+    smtp = &#39;postfix&#39;;
+    smtp_port = 25;
+    from_name = &#39;Example DMARC Report&#39;;
+    msgid_from = &#39;rspamd.mail.example.com&#39;;
+    max_entries = 2k;
+    keys_expire = 2d;
+}
+</code></pre></div>
+<p>Erstellen oder ändern Sie <code>docker-compose.override.yml</code> im mailcow-dockerized Basisverzeichnis:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;

+  ofelia-mailcow:
+    depends_on:

+<p>Um eine versteckte Kopie der von Rspamd erzeugten Berichte zu erhalten, können Sie eine <code>bcc_addrs</code> Liste im <code>reporting</code> Konfigurationsabschnitt von <code>data/conf/rspamd/local.d/dmarc.conf</code> setzen:</p>
+<div class="highlight"><pre><span></span><code>reporting {
+    enabled = true;
+    email = &#39;noreply-dmarc@example.com&#39;;
+    bcc_addrs = [&quot;noreply-dmarc@example.com&quot;, &quot;parsedmarc@example.com&quot;];
+[...]
+</code></pre></div>
+<p>Rspamd lädt Änderungen in Echtzeit, so dass Sie den Container zu diesem Zeitpunkt nicht neu starten müssen.</p>
+<p>Dies kann nützlich sein, wenn Sie...</p>
+<ul>
+<li>...überprüfen wollen, ob Ihre DMARC-Berichte korrekt und authentifiziert gesendet werden.</li>
+<li>...Ihre eigenen Berichte analysieren wollen, um Statistiken zu erhalten, z.B. um sie mit ParseDMARC oder anderen Analysesystemen zu verwenden.</li>
+</ul>
+<h2 id="fehlersuche">Fehlersuche<a class="headerlink" href="#fehlersuche" title="Permanent link">&para;</a></h2>
+<p>Prüfen Sie, wann der Berichtsplan zuletzt ausgeführt wurde:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow date -r /var/lib/rspamd/dmarc_reports_last_log
+</code></pre></div>
+<p>Sehen Sie sich die letzte Berichtsausgabe an:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow cat /var/lib/rspamd/dmarc_reports_last_log
+</code></pre></div>
+<p>Manuelles Auslösen eines DMARC-Berichts:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow rspamadm dmarc_report
+</code></pre></div>
+<p>Bestätigen Sie, dass Rspamd Daten in Redis aufgezeichnet hat:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec redis-mailcow redis-cli KEYS &#39;dmarc;*&#39;
+docker-compose exec redis-mailcow redis-cli HGETALL &quot;dmarc;example.com;20211231&quot;
+</code></pre></div>

+<p>Im obigen Beispiel werden die Berichte einmal alle 24 Stunden gesendet.</p>
+<p>Der Olefia-Zeitplan hat die gleiche Implementierung wie <code>cron</code> in Go, die unterstützte Syntax ist beschrieben in <a href="https://pkg.go.dev/github.com/robfig/cron">cron Documentation</a></p>
+<p>Um den Zeitplan zu ändern:</p>
+<ol>
+<li>
+<p>Bearbeiten Sie <code>docker-compose.override.yml</code> und stellen Sie <code>ofelia.job-exec.rspamd_dmarc_reporting.schedule: "@every 24h"</code> auf einen gewünschten Wert, zum Beispiel auf <code>"@midnight"</code></p>
+</li>
+<li>
+<p>Führen Sie <code>docker-compose up -d</code> aus.</p>
+</li>
+<li>
+<p>Führen Sie <code>docker-compose restart ofelia-mailcow</code> aus</p>
+</li>
+</ol>
+<h2 id="dmarc-berichterstattung-deaktivieren">DMARC-Berichterstattung deaktivieren<a class="headerlink" href="#dmarc-berichterstattung-deaktivieren" title="Permanent link">&para;</a></h2>

+HTTPS_BIND=

+# Andere Dienste werden nach folgendem Format gebunden:

+<h2 id="ipv6-binding">IPv6-Binding<a class="headerlink" href="#ipv6-binding" title="Permanent link">&para;</a></h2>
+<p>Das Ändern von IPv6-Bindings ist anders als bei IPv4. Auch dies hat einen technischen Hintergrund.</p>
+<p>Eine <code>docker-compose.override.yml</code> Datei wird verwendet, anstatt die <code>docker-compose.yml</code> Datei direkt zu bearbeiten. Dies geschieht, um die Aktualisierbarkeit zu erhalten, da die Datei <code>docker-compose.yml</code> regelmäßig aktualisiert wird und Ihre Änderungen höchstwahrscheinlich überschrieben werden.</p>
+<p>Bearbeiten Sie die Datei "docker-compose.override.yml" und erstellen Sie sie mit dem folgenden Inhalt. Ihr Inhalt wird mit der produktiven Datei "docker-compose.yml" zusammengeführt.</p>
+<p>Es wird eine imaginäre IPv6 <strong>2a00:dead:beef::abc</strong> angegeben. Das erste Suffix <code>:PORT1</code> definiert den externen Port, während das zweite Suffix <code>:PORT2</code> zu dem entsprechenden Port innerhalb des Containers führt und nicht verändert werden darf.</p>

+  <h1>Lokaler MTA auf Docker-Host</h1>
+
+<p>Die einfachste Möglichkeit wäre, den Listener an Port 25/tcp zu deaktivieren.</p>
+<p><strong>Postfix</strong>-Benutzer deaktivieren den Listener, indem sie die folgende Zeile (beginnend mit <code>smtp</code> oder <code>25</code>) in <code>/etc/postfix/master.cf</code> auskommentieren:
+<div class="highlight"><pre><span></span><code>#smtp      inet  n       -       -       -       -       smtpd
+</code></pre></div></p>
+<p>Außerdem, um über eine Dockerized mailcow weiterzuleiten, sollten Sie <code>172.22.1.1</code> als Relayhost hinzufügen und das Docker-Interface aus "inet_interfaces" entfernen:</p>
+<div class="highlight"><pre><span></span><code>postconf -e &#39;relayhost = 172.22.1.1&#39;
+postconf -e &quot;mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128&quot;
+postconf -e &quot;inet_interfaces = loopback-only&quot;
+postconf -e &quot;relay_transport = relay&quot;
+postconf -e &quot;default_transport = smtp&quot;
+</code></pre></div>
+<p><strong>Jetzt ist es wichtig</strong>, dass Sie nicht denselben FQDN in <code>myhostname</code> haben, den Sie für Ihre mailcow verwenden. Prüfen Sie Ihre lokale (nicht-Docker) Postfix' main.cf auf <code>myhostname</code> und setzen Sie ihn auf etwas anderes, zum Beispiel <code>local.my.fqdn.tld</code>.</p>
+<p>"172.22.1.1" ist das von mailcow erstellte Netzwerk-Gateway in Docker.
+Das Relaying über diese Schnittstelle ist notwendig (anstatt - zum Beispiel - direkt über ${MAILCOW_HOSTNAME}), um über ein bekanntes internes Netzwerk weiterzuleiten.</p>
+<p>Starten Sie Postfix neu, nachdem Sie Ihre Änderungen vorgenommen haben.</p>

+  <h1>Logging</h1>
+
+<p>Das Logging in mailcow: dockerized besteht aus mehreren Stufen, ist aber immerhin wesentlich flexibler und einfacher in einen Logging-Daemon zu integrieren als bisher.</p>
+<p>In Docker schreibt die containerisierte Anwendung (PID 1) ihre Ausgabe auf stdout. Für echte Ein-Anwendungs-Container funktioniert das sehr gut.
+Führen Sie <code>docker-compose logs --help</code> aus, um mehr zu erfahren. </p>
+<p>Einige Container protokollieren oder streamen an mehrere Ziele.</p>
+<p>Kein Container wird persistente Logs in sich behalten. Container sind flüchtige Objekte!</p>
+<p>Am Ende wird jede Zeile der Logs den Docker-Daemon erreichen - ungefiltert.</p>
+<p>Der <strong>Standard-Logging-Treiber ist "json "</strong>.</p>
+<h3 id="gefilterte-logs">Gefilterte Logs<a class="headerlink" href="#gefilterte-logs" title="Permanent link">&para;</a></h3>
+<p>Einige Logs werden gefiltert und in Redis-Schlüssel geschrieben, aber auch in einen Redis-Kanal gestreamt.</p>
+<p>Der Redis-Kanal wird verwendet, um Protokolle mit fehlgeschlagenen Authentifizierungsversuchen zu streamen, die von netfilter-mailcow gelesen werden.</p>
+<p>Die Redis-Schlüssel sind persistent und halten 10000 Zeilen von Logs für die Web-UI.</p>
+<p>Dieser Mechanismus macht es möglich, jeden beliebigen Docker-Logging-Treiber zu verwenden, ohne die 
+ohne die Fähigkeit zu verlieren, Logs von der UI zu lesen oder verdächtige Clients mit netfilter-mailcow zu sperren.</p>
+<p>Redis-Schlüssel enthalten nur Logs von Anwendungen und filtern Systemmeldungen heraus (man denke an Cron etc.).</p>
+<h3 id="logging-treiber">Logging-Treiber<a class="headerlink" href="#logging-treiber" title="Permanent link">&para;</a></h3>
+<h4 id="uber-docker-composeoverrideyml">Über docker-compose.override.yml<a class="headerlink" href="#uber-docker-composeoverrideyml" title="Permanent link">&para;</a></h4>
+<p>Hier ist die gute Nachricht: Da Docker einige großartige Logging-Treiber hat, können Sie mailcow: dockerized mit Leichtigkeit in Ihre bestehende Logging-Umgebung integrieren.</p>
+<p>Erstellen Sie eine <code>docker-compose.override.yml</code> und fügen Sie zum Beispiel diesen Block hinzu, um das "gelf" Logging-Plugin für <code>postfix-mailcow</code> zu verwenden:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+  postfix-mailcow: # oder ein anderer
+    logging:
+      driver: &quot;gelf&quot;
+      options:
+        gelf-address: &quot;udp://graylog:12201&quot;
+</code></pre></div>
+<p>Ein weiteres Beispiel für <strong>Syslog</strong>:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+  postfix-mailcow: # oder ein anderer
+    logging:
+      driver: &quot;syslog&quot;
+      options:
+        syslog-address: &quot;udp://127.0.0.1:514&quot;
+        syslog-facility: &quot;local3&quot;
+
+  dovecot-mailcow: # oder ein anderer
+    logging:
+      driver: &quot;syslog&quot;
+      options:
+        syslog-address: &quot;udp://127.0.0.1:514&quot;
+        syslog-facility: &quot;local3&quot;
+
+  rspamd-mailcow: # oder ein anderer
+    logging:
+      driver: &quot;syslog&quot;
+      options:
+        syslog-address: &quot;udp://127.0.0.1:514&quot;
+        syslog-facility: &quot;local3&quot;
+
+# Nur für Rsyslog:
+# Um die local3-Eingabe nach /var/log/mailcow.log zu verschieben und die Verarbeitung zu beenden, erstellen Sie eine Datei &quot;/etc/rsyslog.d/docker.conf&quot;:
+
+local3.* /var/log/mailcow.logs
+&amp; ~
+
+# Danach rsyslog neu starten.
+</code></pre></div>
+<h4 id="uber-daemonjson-global">Über daemon.json (global)<a class="headerlink" href="#uber-daemonjson-global" title="Permanent link">&para;</a></h4>
+<p>Wenn Sie den Logging-Treiber <strong>global</strong> ändern wollen, editieren Sie die Konfigurationsdatei des Docker-Daemons <code>/etc/docker/daemon.json</code> und starten Sie den Docker-Dienst neu:</p>
+<div class="highlight"><pre><span></span><code>{
+...
+  &quot;log-driver&quot;: &quot;gelf&quot;,
+  &quot;log-opts&quot;: {
+    &quot;gelf-address&quot;: &quot;udp://graylog:12201&quot;
+  }
+...
+}
+</code></pre></div>
+<p>Für Syslog:</p>
+<div class="highlight"><pre><span></span><code>{
+...
+  &quot;log-driver&quot;: &quot;syslog&quot;,
+  &quot;log-opts&quot;: {
+    &quot;syslog-address&quot;: &quot;udp://1.2.3.4:514&quot;
+  }
+...
+}
+</code></pre></div>
+<p>Starten Sie den Docker-Daemon neu und führen Sie <code>docker-compose down &amp;&amp; docker-compose up -d</code> aus, um die Container mit dem neuen Protokollierungstreiber neu zu erstellen.</p>

+  <h1>Reverse Proxy</h1>
+
+<p>Sie müssen die Nginx-Seite, die mit mailcow: dockerized geliefert wird, nicht ändern.
+mailcow: dockerized vertraut auf das Standard-Gateway IP 172.22.1.1 als Proxy.</p>
+<p>1. Stellen Sie sicher, dass Sie HTTP_BIND und HTTPS_BIND in <code>mailcow.conf</code> auf eine lokale Adresse ändern und die Ports entsprechend einstellen, zum Beispiel:
+<div class="highlight"><pre><span></span><code><span class="nv">HTTP_BIND</span><span class="o">=</span><span class="m">127</span>.0.0.1
+<span class="nv">HTTP_PORT</span><span class="o">=</span><span class="m">8080</span>
+<span class="nv">HTTPS_BIND</span><span class="o">=</span><span class="m">127</span>.0.0.1
+<span class="nv">HTTPS_PORT</span><span class="o">=</span><span class="m">8443</span>
+</code></pre></div></p>
+<p>Dadurch werden auch die Bindungen innerhalb des Nginx-Containers geändert! Dies ist wichtig, wenn Sie sich entscheiden, einen Proxy innerhalb von Docker zu verwenden.</p>
+<p><strong>WICHTIG:</strong> Verwenden Sie nicht Port 8081, 9081 oder 65510!</p>
+<p>Erzeugen Sie die betroffenen Container neu, indem Sie <code>docker-compose up -d</code> ausführen.</p>
+<p><strong>Wichtige Informationen, bitte lesen Sie diese sorgfältig durch!</strong></p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Wenn Sie planen, einen Reverse-Proxy zu verwenden und einen anderen Servernamen als <strong>MAILCOW_HOSTNAME</strong> verwenden wollen, müssen Sie <strong>Zusätzliche Servernamen für mailcow UI</strong> am Ende dieser Seite hinzufügen.</p>
+</div>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Stellen Sie sicher, dass Sie <code>generate_config.sh</code> ausführen, bevor Sie die untenstehenden Konfigurationsbeispiele aktivieren.
+Das Skript <code>generate_config.sh</code> kopiert die Snake-oil Zertifikate an den richtigen Ort, so dass die Dienste nicht aufgrund fehlender Dateien nicht starten können.</p>
+</div>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Wenn du TLS SNI aktivierst (<code>ENABLE_TLS_SNI</code> in mailcow.conf), <strong>müssen</strong> die Zertifikatspfade in deinem Reverse-Proxy mit den korrekten Pfaden in data/assets/ssl/{hostname} übereinstimmen. Die Zertifikate werden in <code>data/assets/ssl/{hostname1,hostname2,etc}</code> aufgeteilt und werden daher nicht funktionieren, wenn Sie die Beispiele von unten kopieren, die auf <code>data/assets/ssl/cert.pem</code> etc. zeigen.</p>
+</div>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Die Verwendung der untenstehenden Site-Konfigurationen wird <strong>acme-Anfragen an mailcow</strong> weiterleiten und es die Zertifikate selbst verwalten lassen.
+Der Nachteil der Verwendung von mailcow als ACME-Client hinter einem Reverse-Proxy ist, dass Sie Ihren Webserver neu laden müssen, nachdem acme-mailcow das Zertifikat geändert/erneuert/erstellt hat. Sie können entweder Ihren Webserver täglich neu laden oder ein Skript schreiben, um die Datei auf Änderungen zu überwachen.
+Auf vielen Servern wird logrotate den Webserver sowieso täglich neu laden.</p>
+<p>Wenn Sie eine lokale Certbot-Installation verwenden möchten, müssen Sie die SSL-Zertifikatsparameter entsprechend ändern.
+<strong>Stellen Sie sicher, dass Sie ein Post-Hook-Skript</strong> ausführen, wenn Sie sich entscheiden, externe ACME-Clients zu verwenden. Ein Beispiel finden Sie am Ende dieser Seite.</p>
+</div>
+<p>2. Konfigurieren Sie Ihren lokalen Webserver als Reverse Proxy:</p>
+<h3 id="apache-24">Apache 2.4<a class="headerlink" href="#apache-24" title="Permanent link">&para;</a></h3>
+<p>Erforderliche Module:
+<div class="highlight"><pre><span></span><code>a2enmod rewrite proxy proxy_http headers ssl
+</code></pre></div></p>
+<p>Let's Encrypt wird unserem Rewrite folgen, Zertifikatsanfragen in mailcow werden problemlos funktionieren.</p>
+<p><strong>Die hervorgehobenen Zeilen müssen beachtet werden</strong>.</p>

+<p><strong>Wichtig</strong>: Diese Konfiguration deckt nur das "Reverseproxing" des Webpanels (nginx-mailcow) unter Verwendung von Traefik v2 ab. Wenn Sie auch die Mail-Dienste wie dovecot, postfix... reproxen wollen, müssen Sie die folgende Konfiguration an jeden Container anpassen und einen <a href="https://docs.traefik.io/routing/entrypoints/">EntryPoint</a> in Ihrer <code>traefik.toml</code> oder <code>traefik.yml</code> (je nachdem, welche Konfiguration Sie verwenden) für jeden Port erstellen. </p>
+<p>In diesem Abschnitt gehen wir davon aus, dass Sie Ihren Traefik 2 <code>[certificatesresolvers]</code> in Ihrer Traefik-Konfigurationsdatei richtig konfiguriert haben und auch acme verwenden. Das folgende Beispiel verwendet Lets Encrypt, aber Sie können es gerne auf Ihren eigenen Zertifikatsresolver ändern. Eine grundlegende Traefik 2 toml-Konfigurationsdatei mit allen oben genannten Elementen, die für dieses Beispiel verwendet werden kann, finden Sie hier <a href="https://github.com/Frenzoid/TraefikBasicConfig/blob/master/traefik.toml">traefik.toml</a>, falls Sie eine solche Datei benötigen oder einen Hinweis, wie Sie Ihre Konfiguration anpassen können.</p>
+<p>Zuallererst werden wir den acme-mailcow-Container deaktivieren, da wir die von traefik bereitgestellten Zertifikate verwenden werden.
+Dazu müssen wir <code>SKIP_LETS_ENCRYPT=y</code> in unserer <code>mailcow.conf</code> setzen und <code>docker-compose up -d</code> ausführen, um die Änderungen zu übernehmen.</p>
+<p>Dann erstellen wir eine <code>docker-compose.override.yml</code> Datei, um die Hauptdatei <code>docker-compose.yml</code> zu überschreiben, die sich im Mailcow-Stammverzeichnis befindet. </p>

Zum Glück haben wir [diesen kleinen Container] (<a href="https://hub.docker.com/r/humenius/traefik-certs-dumper">https://hub.docker.com/r/humenius/traefik-certs-dumper</a>), der die Datei <code>acme.json</code> über ein Volume und eine Variable <code>DOMAIN=example. org</code>, und damit wird der Container die <code>cert.pem</code> und <code>key.pem</code> Dateien ausgeben, dafür lassen wir einfach den <code>traefik-certs-dumper</code> Container laufen, binden das <code>/traefik</code> Volume an den Ordner, in dem unsere <code>acme.json</code> gespeichert ist, binden das <code>/output</code> Volume an unseren mailcow <code>data/assets/ssl/</code> Ordner, und setzen die <code>DOMAIN=example.org</code> Variable auf die Domain, von der wir die Zertifikate ausgeben wollen. </p>
+<p>Dieser Container überwacht die Datei <code>acme.json</code> auf Änderungen und generiert die Dateien <code>cert.pem</code> und <code>key.pem</code> direkt in <code>data/assets/ssl/</code>, wobei der Pfad mit dem <code>/output</code>-Pfad des Containers verbunden ist.</p>
+<p>Sie können es über die Kommandozeile ausführen oder das [hier] gezeigte docker-compose verwenden (<a href="https://hub.docker.com/r/humenius/traefik-certs-dumper">https://hub.docker.com/r/humenius/traefik-certs-dumper</a>).</p>
+<p>Nachdem wir die Zertifikate übertragen haben, müssen wir die Konfigurationen aus unseren Postfix- und Dovecot-Containern neu laden und die Zertifikate überprüfen. Wie das geht, sehen Sie <a href="https://mailcow.github.io/mailcow-dockerized-docs/de/post_installation/firststeps-ssl/#ein-eigenes-zertifikat-verwenden">hier</a>.</p>
+<p>Und das sollte es gewesen sein 😊, Sie können überprüfen, ob der Traefik-Router einwandfrei funktioniert, indem Sie das Dashboard von Traefik / traefik logs / über https auf die eingestellte Domain zugreifen, oder / und HTTPS, SMTP und IMAP mit den Befehlen auf der zuvor verlinkten Seite überprüfen.</p>

+<p>Die Verwendung eines lokalen Certbots (oder eines anderen ACME-Clients) erfordert den Neustart einiger Container, was Sie mit einem Post-Hook-Skript erledigen können.
+Stellen Sie sicher, dass Sie die Pfade entsprechend ändern:

+<p>Wenn Sie vorhaben, einen Servernamen zu verwenden, der nicht <code>MAILCOW_HOSTNAME</code> in Ihrem Reverse-Proxy ist, stellen Sie sicher, dass Sie diesen Namen zuerst in mailcow.conf über <code>ADDITIONAL_SERVER_NAMES</code> einpflegen. Die Namen müssen durch Kommas getrennt werden und <strong>dürfen</strong> keine Leerzeichen enthalten. Wenn Sie diesen Schritt überspringen, kann es sein, dass mailcow auf Ihren Reverse-Proxy mit einer falschen Seite antwortet.</p>
+<div class="highlight"><pre><span></span><code>ADDITIONAL_SERVER_NAMES=webmail.domain.tld,other.example.tld

+  <h1>SNAT</h1>
+
+<p>SNAT wird verwendet, um die Quelladresse der von mailcow gesendeten Pakete zu ändern.
+Es kann verwendet werden, um die ausgehende IP-Adresse auf Systemen mit mehreren IP-Adressen zu ändern.</p>
+<p>Öffnen Sie <code>mailcow.conf</code>, setzen Sie einen oder beide der folgenden Parameter:</p>
+<div class="highlight"><pre><span></span><code># Benutze diese IPv4 für ausgehende Verbindungen (SNAT)
+SNAT_TO_SOURCE=1.2.3.4
+
+# Benutze dieses IPv6 für ausgehende Verbindungen (SNAT)
+SNAT6_TO_SOURCE=dead:beef
+</code></pre></div>
+<p>Führen Sie <code>docker-compose up -d</code> aus.</p>
+<p>Die Werte werden von netfilter-mailcow gelesen. netfilter-mailcow stellt sicher, dass die Post-Routing-Regeln auf Position 1 in der Netfilter-Tabelle stehen. Es löscht sie automatisch und legt sie neu an, wenn sie an einer anderen Position als 1 gefunden werden.</p>
+<p>Überprüfen Sie die Ausgabe von <code>docker-compose logs --tail=200 netfilter-mailcow</code>, um sicherzustellen, dass die SNAT-Einstellungen angewendet wurden.</p>

+<p>Der "acme-mailcow" Container wird versuchen, ein LE-Zertifikat für <code>${MAILCOW_HOSTNAME}</code>, <code>autodiscover.ADDED_MAIL_DOMAIN</code> und <code>autoconfig.ADDED_MAIL_DOMAIN</code> zu erhalten.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>mailcow <strong>muss</strong> auf Port 80 verfügbar sein, damit der acme-Client funktioniert. Unsere Reverse Proxy Beispielkonfigurationen decken das ab. Sie können auch jeden externen ACME-Client (z.B. certbot) verwenden, um Zertifikate zu erhalten, aber Sie müssen sicherstellen, dass sie an den richtigen Ort kopiert werden und ein Post-Hook die betroffenen Container neu lädt. Weitere Informationen finden Sie in der Reverse Proxy-Dokumentation.</p>
+</div>
+<p>Standardmäßig, d.h. <strong>0 Domains</strong> sind zu mailcow hinzugefügt, wird es versuchen, ein Zertifikat für <code>${MAILCOW_HOSTNAME}</code> zu erhalten.</p>
+<p>Für jede hinzugefügte Domain wird versucht, <code>autodiscover.ADDED_MAIL_DOMAIN</code> und <code>autoconfig.ADDED_MAIL_DOMAIN</code> in die IPv6-Adresse oder - falls IPv6 in der Domain nicht konfiguriert ist - in die IPv4-Adresse aufzulösen. Wenn dies gelingt, wird ein Name als SAN zur Zertifikatsanforderung hinzugefügt.</p>
+<p>Nur Namen, die validiert werden können, werden als SAN hinzugefügt.</p>
+<p>Für jede Domain, die Sie entfernen, wird das Zertifikat verschoben und ein neues Zertifikat angefordert. Es ist nicht möglich, Domains in einem Zertifikat zu behalten, wenn wir nicht in der Lage sind, die Challenge für diese zu validieren.</p>
+<p>Wenn Sie den ACME-Client neu starten wollen, verwenden Sie <code>docker-compose restart acme-mailcow</code> und überwachen Sie die Protokolle mit <code>docker-compose logs --tail=200 -f acme-mailcow</code>.</p>
+<h3 id="zusatzliche-domain-namen">Zusätzliche Domain-Namen<a class="headerlink" href="#zusatzliche-domain-namen" title="Permanent link">&para;</a></h3>
+<p>Bearbeiten Sie "mailcow.conf" und fügen Sie einen Parameter <code>ADDITIONAL_SAN</code> wie folgt hinzu:</p>
+<p>Verwenden Sie keine Anführungszeichen (<code>"</code>) und keine Leerzeichen zwischen den Namen!</p>
+<div class="highlight"><pre><span></span><code>ADDITIONAL_SAN=smtp.*,cert1.example.com,cert2.example.org,whatever.*
+</code></pre></div>
+<p>Jeder Name wird anhand seiner IPv6-Adresse oder - wenn IPv6 in Ihrer Domäne nicht konfiguriert ist - anhand seiner IPv4-Adresse überprüft.</p>
+<p>Ein Wildcard-Name wie <code>smtp.*</code> wird versuchen, ein smtp.DOMAIN_NAME SAN für jede zu mailcow hinzugefügte Domain zu erhalten.</p>
+<p>Führen Sie <code>docker-compose up -d</code> aus, um betroffene Container automatisch neu zu erstellen.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Die Verwendung anderer Namen als <code>MAILCOW_HOSTNAME</code> für den Zugriff auf das mailcow UI kann weitere Konfiguration erfordern.</p>
+</div>
+<p>Wenn Sie planen, einen anderen Servernamen als <code>MAILCOW_HOSTNAME</code> für den Zugriff auf die mailcow UI zu verwenden (z.B. durch Hinzufügen von <code>mail.*</code> zu <code>ADDITIONAL_SAN</code>), stellen Sie sicher, dass Sie diesen Namen in mailcow.conf über <code>ADDITIONAL_SERVER_NAMES</code> eintragen. Die Namen müssen durch Kommas getrennt sein und <strong>dürfen</strong> keine Leerzeichen enthalten. Wenn Sie diesen Schritt auslassen, kann mailcow mit einer falschen Seite antworten.</p>
+<div class="highlight"><pre><span></span><code>ADDITIONAL_SERVER_NAMES=webmail.domain.tld,other.example.tld
+</code></pre></div>
+<p>Führen Sie <code>docker-compose up -d</code> aus, um es anzuwenden.</p>
+<h3 id="erneuerung-erzwingen">Erneuerung erzwingen<a class="headerlink" href="#erneuerung-erzwingen" title="Permanent link">&para;</a></h3>
+<p>Um eine Erneuerung zu erzwingen, müssen Sie eine Datei namens <code>force_renew</code> erstellen und den <code>acme-mailcow</code> Container neu starten:</p>
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+touch data/assets/ssl/force_renew
+docker-compose restart acme-mailcow
+# Prüfen Sie nun die Logs auf eine Erneuerung
+docker-compose logs --tail=200 -f acme-mailcow
+</code></pre></div>
+<p>Die Datei wird automatisch gelöscht.</p>
+<h3 id="validierungsfehler-und-wie-man-die-validierung-uberspringt">Validierungsfehler und wie man die Validierung überspringt<a class="headerlink" href="#validierungsfehler-und-wie-man-die-validierung-uberspringt" title="Permanent link">&para;</a></h3>
+<p>Sie können die <strong>IP-Überprüfung</strong> überspringen, indem Sie <code>SKIP_IP_CHECK=y</code> in mailcow.conf setzen (keine Anführungszeichen). Seien Sie gewarnt, dass eine Fehlkonfiguration dazu führt, dass Sie von Let's Encrypt eingeschränkt werden! Dies ist vor allem für Multi-IP-Setups nützlich, bei denen der IP-Check die falsche Quell-IP-Adresse zurückgeben würde. Aufgrund der Verwendung von dynamischen IPs für acme-mailcow ist Source-NAT bei Neustarts nicht konsistent.</p>
+<p>Wenn Sie Probleme mit der "HTTP-Validierung" haben, aber Ihre IP-Adressbestätigung erfolgreich ist, verwenden Sie höchstwahrscheinlich firewalld, ufw oder eine andere Firewall, die Verbindungen von <code>br-mailcow</code> zu Ihrem externen Interface verbietet. Sowohl firewalld als auch ufw lassen dies standardmäßig nicht zu. Es reicht oft nicht aus, diese Firewall-Dienste einfach zu stoppen. Sie müssen mailcow stoppen (<code>docker-compose down</code>), den Firewall-Dienst stoppen, die Ketten flushen und Docker neu starten.</p>
+<p>Sie können diese Validierungsmethode auch überspringen, indem Sie <code>SKIP_HTTP_VERIFICATION=y</code> in "mailcow.conf" setzen. Seien Sie gewarnt, dass dies nicht zu empfehlen ist. In den meisten Fällen wird die HTTP-Überprüfung übersprungen, um unbekannte NAT-Reflection-Probleme zu umgehen, die durch das Ignorieren dieser spezifischen Netzwerk-Fehlkonfiguration nicht gelöst werden. Wenn Sie Probleme haben, TLSA-Einträge in der DNS-Übersicht innerhalb von mailcow zu generieren, haben Sie höchstwahrscheinlich Probleme mit NAT-Reflexion, die Sie beheben sollten.</p>
+<p>Wenn du einen SKIP_* Parameter geändert hast, führe <code>docker-compose up -d</code> aus, um deine Änderungen zu übernehmen.</p>

+<p>Let's Encrypt hat derzeit <a href="https://letsencrypt.org/docs/rate-limits/">ein Limit von 100 Domainnamen pro Zertifikat</a>.</p>
+<p>Standardmäßig erstellt "acme-mailcow" ein einzelnes SAN-Zertifikat für alle validierten Domains
+(siehe den <a href="#lets-encrypt-wird-mitgeliefert">ersten Abschnitt</a> und <a href="#zusatzliche-domain-namen">Zusätzliche Domainnamen</a>).
+Dies bietet beste Kompatibilität, bedeutet aber, dass das Let's Encrypt-Limit überschritten wird, wenn Sie zu viele Domains zu einer einzelnen Mailcow-Installation hinzufügen.</p>
+<p>Um dies zu lösen, können Sie <code>ENABLE_SSL_SNI</code> so konfigurieren, dass es generiert wird:</p>

+<li>Ein Hauptserver-Zertifikat mit <code>MAILCOW_HOSTNAME</code> und allen voll qualifizierten Domainnamen in der <code>ADDITIONAL_SAN</code> Konfiguration</li>
+<li>Ein zusätzliches Zertifikat für jede in der Datenbank gefundene Domain mit autodiscover.<em>, autoconfig.</em> und jeder anderen in diesem Format konfigurierten <code>ADDITIONAL_SAN</code> (subdomain.*).</li>
+<li>Begrenzungen: Ein Zertifikatsname <code>ADDITIONAL_SAN=test.example.com</code> wird als SAN zum Hauptzertifikat hinzugefügt. Ein separates Zertifikat/Schlüsselpaar wird für dieses Format <strong>nicht</strong> erzeugt.</li>
+</ul>
+<p>Postfix, Dovecot und Nginx werden dann diese Zertifikate mit SNI bedienen.</p>
+<p>Setzen Sie <code>ENABLE_SSL_SNI=y</code> in "mailcow.conf" und erstellen Sie "acme-mailcow" durch Ausführen von <code>docker-compose up -d</code>.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Nicht alle Clients unterstützen SNI, <a href="https://wiki.dovecot.org/SSL/SNIClientSupport">siehe Dovecot Dokumentation</a> oder <a href="https://en.wikipedia.org/wiki/Server_Name_Indication#Support">Wikipedia</a>.
+Sie sollten sicherstellen, dass diese Clients den <code>MAILCOW_HOSTNAME</code> für sichere Verbindungen verwenden, wenn Sie diese Funktion aktivieren.</p>
+</div>
+<p>Hier ist ein Beispiel:</p>
+<ul>
+<li><code>MAILCOW_HOSTNAME=server.email.tld</code></li>
+<li><code>ADDITIONAL_SAN=webmail.email.tld,mail.*</code></li>
+<li>Mailcow E-Mail-Domänen: "domain1.tld" und "domain2.tld"</li>
+</ul>
+<p>Die folgenden Zertifikate werden generiert:</p>
+<ul>
+<li><code>server.email.tld, webmail.email.tld</code> -&gt; dies ist das Standard-Zertifikat, alle Clients können sich mit diesen Domains verbinden</li>
+<li><code>mail.domain1.tld, autoconfig.domain1.tld, autodiscover.domain1.tld</code> -&gt; individuelles Zertifikat für domain1.tld, kann von Clients ohne SNI-Unterstützung nicht verwendet werden</li>
+<li><code>mail.domain2.tld, autoconfig.domain2.tld, autodiscover.domain2.tld</code> -&gt; individuelles Zertifikat für domain2.tld, kann von Clients ohne SNI-Unterstützung nicht verwendet werden</li>
+</ul>
+<h3 id="ein-eigenes-zertifikat-verwenden">Ein eigenes Zertifikat verwenden<a class="headerlink" href="#ein-eigenes-zertifikat-verwenden" title="Permanent link">&para;</a></h3>
+<p>Stellen Sie sicher, dass Sie mailcows internen LE-Client deaktivieren (siehe oben).</p>
+<p>Um Ihre eigenen Zertifikate zu verwenden, speichern Sie einfach das kombinierte Zertifikat (mit dem Zertifikat und der zwischengeschalteten CA/CA, falls vorhanden) unter <code>data/assets/ssl/cert.pem</code> und den entsprechenden Schlüssel unter <code>data/assets/ssl/key.pem</code>.</p>
+<p><strong>WICHTIG:</strong> Verwenden Sie keine symbolischen Links! Stellen Sie sicher, dass Sie die Zertifikate kopieren und sie nicht mit <code>data/assets/ssl</code> verknüpfen.</p>
+<p>Starten Sie die betroffenen Dienste anschließend neu:</p>
+<div class="highlight"><pre><span></span><code>docker restart $(docker ps -qaf name=postfix-mailcow)
+docker neu starten $(docker ps -qaf name=nginx-mailcow)
+docker restart $(docker ps -qaf name=dovecot-mailcow)
+</code></pre></div>
+<p>Siehe <a href="../post_installation/firststeps-rp#optional-post-hook-skript-fur-nicht-mailcow-acme-clients">Post-Hook-Skript für Nicht-Mailcow-ACME-Clients</a> für ein vollständiges Beispielskript.</p>
+<h3 id="test-gegen-das-acme-verzeichnis">Test gegen das ACME-Verzeichnis<a class="headerlink" href="#test-gegen-das-acme-verzeichnis" title="Permanent link">&para;</a></h3>
+<p>Bearbeiten Sie <code>mailcow.conf</code> und fügen Sie <code>LE_STAGING=y</code> hinzu.</p>
+<p>Führen Sie <code>docker-compose up -d</code> aus, um Ihre Änderungen zu aktivieren.</p>
+<h3 id="benutzerdefinierte-verzeichnis-url">Benutzerdefinierte Verzeichnis-URL<a class="headerlink" href="#benutzerdefinierte-verzeichnis-url" title="Permanent link">&para;</a></h3>
+<p>Editieren Sie <code>mailcow.conf</code> und fügen Sie die entsprechende Verzeichnis-URL in die neue Variable <code>DIRECTORY_URL</code> ein:</p>
+<div class="highlight"><pre><span></span><code>DIRECTORY_URL=https://acme-custom-v9000.api.letsencrypt.org/directory
+</code></pre></div>
+<p>Sie können <code>LE_STAGING</code> nicht mit <code>DIRECTORY_URL</code> verwenden. Wenn beide gesetzt sind, wird nur <code>LE_STAGING</code> verwendet.</p>
+<p>Führen Sie <code>docker-compose up -d</code> aus, um Ihre Änderungen zu aktivieren.</p>
+<h3 id="uberprufen-sie-ihre-konfiguration">Überprüfen Sie Ihre Konfiguration<a class="headerlink" href="#uberprufen-sie-ihre-konfiguration" title="Permanent link">&para;</a></h3>
+<p>Führen Sie <code>docker-compose logs acme-mailcow</code> aus, um herauszufinden, warum eine Validierung fehlschlägt.</p>
+<p>Um zu überprüfen, ob nginx das richtige Zertifikat verwendet, benutzen Sie einfach einen Browser Ihrer Wahl und überprüfen Sie das angezeigte Zertifikat.</p>
+<p>Um das von Postfix, Dovecot und Nginx verwendete Zertifikat zu überprüfen, verwenden wir <code>openssl</code>:</p>
+<div class="highlight"><pre><span></span><code># Verbindung über SMTP (587)
+echo &quot;Q&quot; | openssl s_client -starttls smtp -crlf -connect mx.mailcow.email:587
+# Verbindung über IMAP (143)
+echo &quot;Q&quot; | openssl s_client -starttls imap -showcerts -connect mx.mailcow.email:143
+# Verbindung über HTTPS (443)
+echo &quot;Q&quot; | openssl s_client -connect mx.mailcow.email:443
+</code></pre></div>
+<p>Um die von openssl zurückgegebenen Verfallsdaten gegen MAILCOW_HOSTNAME zu validieren, können Sie unser Hilfsskript verwenden:</p>
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+bash helper-scripts/expiry-dates.sh
+</code></pre></div>

+  <h1>Migration von Sync-Jobs</h1>
+
+<p>Sync-Aufträge werden verwendet, um bestehende E-Mails von einem externen IMAP-Server oder innerhalb von mailcow's bestehenden Mailboxen zu kopieren oder zu verschieben.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Abhängig von der ACL Ihrer Mailbox haben Sie möglicherweise nicht die Möglichkeit, einen Sync-Job hinzuzufügen. Bitte kontaktieren Sie in diesem Fall Ihren Domain-Administrator.</p>
+</div>
+<h2 id="einrichten-eines-sync-jobs">Einrichten eines Sync-Jobs<a class="headerlink" href="#einrichten-eines-sync-jobs" title="Permanent link">&para;</a></h2>
+<ol>
+<li>
+<p>Erstellen Sie unter dem Punkt "Konfiguration &gt; E-Mail-Setup" oder "Benutzereinstellungen" einen neuen Synchronisierungsauftrag.</p>
+</li>
+<li>
+<p>Wenn Sie ein Administrator sind, wählen Sie den Benutzernamen der nachgelagerten mailcow-Mailbox im Dropdown-Menü "Benutzername".</p>
+</li>
+<li>
+<p>Füllen Sie die Felder "Host" und "Port" mit den entsprechenden korrekten Werten des vorgelagerten IMAP-Servers aus.</p>
+</li>
+<li>
+<p>Geben Sie in den Feldern "Benutzername" und "Passwort" die korrekten Zugangsdaten des vorgelagerten IMAP-Servers ein.</p>
+</li>
+<li>
+<p>Wählen Sie die "Verschlüsselungsmethode". Wenn der vorgelagerte IMAP-Server Port 143 verwendet, ist es wahrscheinlich, dass die Verschlüsselungsmethode TLS und SSL für Port 993 ist. Sie können auch PLAIN-Authentifizierung verwenden, aber davon wird dringend abgeraten.</p>
+</li>
+<li>
+<p>Alle anderen Felder können Sie so lassen, wie sie sind, oder sie nach Belieben ändern.</p>
+</li>
+<li>
+<p>Vergewissern Sie sich, dass Sie "Aktiv" ankreuzen und klicken Sie auf "Hinzufügen".</p>
+</li>
+</ol>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Sobald Sie fertig sind, melden Sie sich in der Mailbox an und überprüfen Sie, ob alle E-Mails korrekt importiert wurden. Wenn alles gut geht, werden alle Ihre E-Mails in Ihrem neuen Postfach landen. Vergessen Sie nicht, den Synchronisierungsauftrag zu löschen oder zu deaktivieren, nachdem er verwendet wurde.</p>

+<p>Nachstehend finden Sie eine Liste von <strong>empfohlenen DNS-Einträgen</strong>. Einige sind für einen Mailserver obligatorisch (A, MX), andere werden empfohlen, um eine gute Reputation aufzubauen (TXT/SPF) oder für die automatische Konfiguration von Mailclients verwendet (SRV).</p>

+<p>Stellen Sie sicher, dass der PTR-Eintrag Ihrer IP-Adresse mit dem FQDN Ihres mailcow-Hosts übereinstimmt: <code>${MAILCOW_HOSTNAME}</code> <sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup>. Dieser Eintrag wird normalerweise bei dem Provider gesetzt, von dem Sie die IP-Adresse (Server) gemietet haben.</p>

+<p>Dieses Beispiel zeigt Ihnen eine Reihe von Einträgen für eine von mailcow verwaltete Domain. Jede Domain, die zu mailcow hinzugefügt wird, benötigt mindestens diesen Satz an Einträgen, um korrekt zu funktionieren.</p>
+<div class="highlight"><pre><span></span><code># Name Typ Wert

+autodiscover IN CNAME mail.example.org. (Ihr ${MAILCOW_HOSTNAME})

+</code></pre></div>
+<h2 id="dkim-spf-und-dmarc">DKIM, SPF und DMARC<a class="headerlink" href="#dkim-spf-und-dmarc" title="Permanent link">&para;</a></h2>
+<p>Im folgenden Beispiel für eine DNS-Zonendatei wird ein einfacher <strong>SPF</strong> TXT-Eintrag verwendet, um nur DIESEM Server (dem MX) zu erlauben, E-Mails für Ihre Domäne zu senden. Jeder andere Server ist nicht zugelassen, kann es aber tun ("<code>~all</code>"). Weitere Informationen finden Sie im [SPF-Projekt] (<a href="http://www.open-spf.org/">http://www.open-spf.org/</a>).</p>
+<div class="highlight"><pre><span></span><code># Name Typ Wert
+@ IN TXT &quot;v=spf1 mx a -all&quot;
+</code></pre></div>
+<p>Es wird dringend empfohlen, einen <strong>DKIM</strong> TXT-Eintrag in Ihrer mailcow UI zu erstellen und den entsprechenden TXT-Eintrag in Ihren DNS-Einträgen zu setzen. Bitte lesen Sie <a href="http://www.opendkim.org">OpenDKIM</a> für weitere Informationen.</p>
+<div class="highlight"><pre><span></span><code># Name Typ Wert
+dkim._domainkey IN TXT &quot;v=DKIM1; k=rsa; t=s; s=email; p=...&quot;
+</code></pre></div>
+<p>Der letzte Schritt, um sich selbst und andere zu schützen, ist die Implementierung eines <strong>DMARC</strong> TXT-Datensatzes, zum Beispiel mit Hilfe des <a href="http://www.kitterman.com/dmarc/assistant.html">DMARC-Assistenten</a> (<a href="https://dmarcian.com/dmarc-inspector/google.com">check</a>).</p>
+<div class="highlight"><pre><span></span><code># Name Typ Wert

+<p><strong>SRV</strong>-Einträge geben den/die Server für ein bestimmtes Protokoll in Ihrer Domäne an. Wenn Sie einen Dienst explizit als nicht bereitgestellt ankündigen wollen, geben Sie "." als Zieladresse an (statt "mail.example.org."). Bitte beachten Sie [RFC 2782] (<a href="https://tools.ietf.org/html/rfc2782">https://tools.ietf.org/html/rfc2782</a>).</p>

+<p class="admonition-title">Warning</p>
+<p>Versuchen Sie <strong>nicht</strong>, mailcow auf einem Synology/QNAP-Gerät (jedes NAS), OpenVZ, LXC oder anderen Container-Plattformen zu installieren. KVM, ESX, Hyper-V und andere vollständige Virtualisierungsplattformen werden unterstützt.</p>
+</div>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<ul>
+<li>mailcow: dockerized erfordert, dass <a href="#standard-ports">einige Ports</a> für eingehende Verbindungen offen sind, also stellen Sie sicher, dass Ihre Firewall diese nicht blockiert.</li>
+<li>Stellen Sie sicher, dass keine andere Anwendung die Konfiguration von mailcow stört, wie z.B. ein anderer Maildienst</li>
+<li>Ein korrektes DNS-Setup ist entscheidend für jedes gute Mailserver-Setup, also stellen Sie bitte sicher, dass Sie zumindest die <a href="../prerequisite-dns/#die-minimale-dns-konfiguration">basics</a> abgedeckt haben, bevor Sie beginnen!</li>
+<li>Stellen Sie sicher, dass Ihr System ein korrektes Datum und eine korrekte <a href="#datum-und-uhrzeit">Zeiteinstellung</a> hat. Dies ist entscheidend für verschiedene Komponenten wie die Zwei-Faktor-TOTP-Authentifizierung.</li>

+<p>Wir empfehlen, jede Distribution zu verwenden, die von Docker CE unterstützt wird (siehe <a href="https://docs.docker.com/install/">https://docs.docker.com/install/</a>). Wir testen auf CentOS 7, Debian 10/11 und Ubuntu 18.04/20.04.</p>
+<p>ClamAV und Solr können gierig nach RAM sein. Du kannst sie in <code>mailcow.conf</code> durch die Einstellungen <code>SKIP_CLAMD=y</code> und <code>SKIP_SOLR=y</code> deaktivieren.</p>
+<p><strong>Info</strong>: Wir sind uns bewusst, dass ein reiner MTA auf 128 MiB RAM laufen kann. mailcow ist eine ausgewachsene und gebrauchsfertige Groupware mit vielen Extras, die das Leben einfacher machen. mailcow kommt mit einem Webserver, Webmailer, ActiveSync (MS), Antivirus, Antispam, Indexierung (Solr), Dokumentenscanner (Oletools), SQL (MariaDB), Cache (Redis), MDA, MTA, verschiedenen Webdiensten etc.</p>
+<p>Ein einzelner SOGo-Worker <strong>kann</strong> ~350 MiB RAM belegen, bevor er geleert wird. Je mehr ActiveSync-Verbindungen Sie verwenden möchten, desto mehr RAM wird benötigt. In der Standardkonfiguration werden 20 Arbeiter erzeugt.</p>
+<h4 id="beispiele-fur-die-verwendung">Beispiele für die Verwendung<a class="headerlink" href="#beispiele-fur-die-verwendung" title="Permanent link">&para;</a></h4>
+<p>Ein Unternehmen mit 15 Telefonen (EAS aktiviert) und etwa 50 gleichzeitigen IMAP-Verbindungen sollte 16 GiB RAM einplanen.</p>
+<p>6 GiB RAM + 1 GiB Swap sind für die meisten privaten Installationen ausreichend, während 8 GiB RAM für ~5 bis 10 Benutzer empfohlen werden.</p>
+<p>Im Rahmen unseres Supports können wir Ihnen bei der korrekten Planung Ihres Setups helfen.</p>

+<div class="admonition warnung">
+<p class="admonition-title">Warnung</p>
+<p>Es gibt einige Probleme mit dem Betrieb von mailcow auf einem Firewalld/ufw aktivierten System. Sie sollten es deaktivieren (wenn möglich) und stattdessen Ihren Regelsatz in die DOCKER-USER-Kette verschieben, die nicht durch einen Neustart des Docker-Dienstes gelöscht wird. Siehe <a href="https://blog.donnex.net/docker-and-iptables-filtering/">diese (blog.donnex.net)</a> oder <a href="https://unrouted.io/2017/08/15/docker-firewall/">diese (unrouted.io)</a> Anleitung für Informationen darüber, wie man iptables-persistent mit der DOCKER-USER Kette benutzt.
+Da mailcow im Docker-Modus läuft, haben INPUT-Regeln keinen Effekt auf die Beschränkung des Zugriffs auf mailcow. Verwenden Sie stattdessen die FORWARD-Kette.</p>
+</div>
+<p>Wenn dieser Befehl irgendwelche Ergebnisse liefert, entfernen oder stoppen Sie bitte die Anwendung, die auf diesem Port läuft. Sie können mailcows Ports auch über die Konfigurationsdatei <code>mailcow.conf</code> anpassen.</p>

+<p>Für alle, die mit der Hetzner-Firewall zu kämpfen haben:</p>
+<p>Port 53 ist in diesem Fall für die Firewall-Konfiguration unwichtig. Laut Dokumentation verwendet unbound den Portbereich 1024-65535 für ausgehende Anfragen.
+Da es sich bei der Hetzner Robot Firewall um eine statische Firewall handelt (jedes eingehende Paket wird isoliert geprüft) - müssen die folgenden Regeln angewendet werden:</p>
+<p><strong>Für TCP</strong>
+<div class="highlight"><pre><span></span><code>SRC-IP: ---
+DST-IP: ---
+SRC-Port: ---
+DST-Port: 1024-65535
+Protokoll: tcp
+TCP-Flags: ack
+Aktion:      Akzeptieren
+</code></pre></div></p>
+<p><strong>Für UDP</strong>
+<div class="highlight"><pre><span></span><code>SRC-IP: ---
+DST-IP: ---
+SRC-Port: ---
+DST-Port: 1024-65535
+Protokoll: udp
+Aktion:      Akzeptieren
+</code></pre></div></p>
+<p>Wenn man einen restriktiveren Portbereich anwenden will, muss man zuerst die Konfiguration von unbound ändern (nach der Installation):</p>
+<p>{mailcow-dockerized}/data/conf/unbound/unbound.conf:
+<div class="highlight"><pre><span></span><code>ausgehender-Port-vermeiden: 0-32767
+</code></pre></div></p>
+<p>Nun können die Firewall-Regeln wie folgt angepasst werden:</p>
+<div class="highlight"><pre><span></span><code>[...]
+DST Port: 32768-65535
+[...]
+</code></pre></div>

+<p>Borgmatic ist ein großartiger Weg, um Backups auf Ihrem Mailcow-Setup durchzuführen, da es Ihre Daten sicher verschlüsselt und extrem einfach zu
+einzurichten.</p>
+<p>Aufgrund seiner Deduplizierungsfähigkeiten können Sie eine große Anzahl von Backups speichern, ohne große Mengen an Speicherplatz zu verschwenden.
+Speicherplatz zu verschwenden. So können Sie Backups in sehr kurzen Abständen durchführen, um einen minimalen Datenverlust zu gewährleisten, wenn die Notwendigkeit besteht
+Daten aus einer Sicherung wiederherzustellen.</p>
+<p>Dieses Dokument führt Sie durch den Prozess zur Aktivierung kontinuierlicher Backups für mailcow mit borgmatic. Die borgmatic
+Funktionalität wird durch das <a href="https://github.com/b3vis/docker-borgmatic">borgmatic Docker image von b3vis</a> bereitgestellt. Schauen Sie sich
+die <code>README</code> in diesem Repository, um mehr über die anderen Optionen (wie z.B. Push-Benachrichtigungen) zu erfahren, die verfügbar sind.

+<p>Diese Datei ist ein minimales Beispiel für die Verwendung von borgmatic mit einem Konto <code>user</code> beim Cloud-Speicheranbieter <code>rsync.net</code> für

+  <h1>Exchange Hybrid Setup</h1>
+
+<p>Die Verwendung von Microsoft Exchange in einem hybriden Setup ist mit mailcow möglich. Mit diesem Setup können Sie Postfächer auf Ihrer mailcow hinzufügen und trotzdem <a href="https://docs.microsoft.com/microsoft-365/security/office-365-security/exchange-online-protection-overview?view=o365-worldwide">Exchange Online Protection</a> nutzen.
+<strong>Alle Postfächer, die in Exchange eingerichtet sind, erhalten ihre Mails wie gewohnt</strong>, während mit dem hybriden Ansatz zusätzliche Postfächer in mailcow ohne weitere Konfiguration eingerichtet werden können.</p>
+<p>Dieses Setup ist sehr praktisch, wenn Sie die <a href="https://docs.microsoft.com/azure/active-directory/fundamentals/concept-fundamentals-security-defaults">Office 365 Sicherheitsvorgaben</a> aktiviert haben und Anwendungen von Drittanbietern sich nicht mehr in Ihre Postfächer mit einer der <a href="https://docs.microsoft.com/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365">unterstützten Methoden</a> einloggen können.</p>
+<h2 id="voraussetzungen">Voraussetzungen<a class="headerlink" href="#voraussetzungen" title="Permanent link">&para;</a></h2>
+<ul>
+<li>Der mx Record Ihrer Domain muss auf den Exchange Mail Service zeigen. Melden Sie sich in Ihrem Admin-Center an und suchen Sie in den DNS-Einstellungen Ihrer Domäne nach Ihrer personalisierten Gateway-Domäne. Sie sollte wie folgt aussehen: <code>contoso-com.mail.protection.outlook.com</code>. Wenden Sie sich an Ihren Domainregistrator, um weitere Informationen zur Änderung des mx-Eintrags zu erhalten.</li>
+<li>Die Domäne, für die Sie zusätzliche Postfächer haben möchten, muss in Exchange als "Interne Relay-Domäne" eingerichtet werden.<ol>
+<li>Melden Sie sich bei Ihrem <a href="https://admin.exchange.microsoft.com">Exchange Admin Center</a> an.</li>
+<li>Wählen Sie den Bereich "Mailflow" und klicken Sie auf "Akzeptierte Domänen".</li>
+<li>Wählen Sie die Domäne aus und schalten Sie sie von "autorisiert" auf "internes Relais" um.</li>
+</ol>
+</li>
+</ul>

+<p>Ihre Mailcow muss alle Mails an Ihren personalisierten Exchange Host weiterleiten. Es ist die gleiche Host-Adresse, die wir bereits für den mx Record gesucht haben.</p>

+<li><a href="../../manual-guides/Postfix/u_e-postfix-relayhost/">Fügen Sie Ihre personalisierte Exchange Host Adresse als relayhost hinzu</a></li>

+<p>Von nun an wird Ihre Mailcow alle Mails akzeptieren, die von Exchange weitergeleitet werden. Die <strong>Eingangsfilterung und damit das neuronale Lernen Ihrer Kuh wird nicht mehr funktionieren</strong>. Da alle Mails über Exchange geroutet werden, wird der <a href="https://docs.microsoft.com/exchange/antispam-and-antimalware/antispam-and-antimalware?view=exchserver-2019">Filterungsprozess dort abgewickelt</a>.</p>

+<p>Der gesamte Mailverkehr läuft nun über Exchange. Zu diesem Zeitpunkt filtert der Exchange Online-Schutz bereits alle ein- und ausgehenden Mails. Jetzt müssen wir zwei Konnektoren einrichten, um eingehende Mails von unserem Exchange Service an die Mailcow weiterzuleiten und einen weiteren, um Mails zuzulassen, die von der Mailcow an unseren Exchange Service weitergeleitet werden. Sie können der [offiziellen Anleitung von Microsoft] folgen (<a href="https://docs.microsoft.com/exchange/mail-flow-best-practices/use-connectors-to-configure-mail-flow/set-up-connectors-to-route-mail#2-set-up-a-connector-from-microsoft-365-or-office-365-to-your-email-server">https://docs.microsoft.com/exchange/mail-flow-best-practices/use-connectors-to-configure-mail-flow/set-up-connectors-to-route-mail#2-set-up-a-connector-from-microsoft-365-or-office-365-to-your-email-server</a>).</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Für den Connector, der die Mails von Ihrer Mailcow zu Exchange weiterleitet, bietet Microsoft zwei Möglichkeiten der Authentifizierung an. Der empfohlene Weg ist die Verwendung eines tls-Zertifikats, das mit einem Subject-Namen konfiguriert ist, der mit einer akzeptierten Domäne in Exchange übereinstimmt. Andernfalls müssen Sie die Authentifizierung mit der statischen IP-Adresse Ihrer Mailcow wählen.</p>
+</div>
+<h2 id="validierung">Validierung<a class="headerlink" href="#validierung" title="Permanent link">&para;</a></h2>
+<p>Der einfachste Weg, die hybride Einrichtung zu überprüfen, ist das Senden einer Mail aus dem Internet an eine Mailbox, die nur auf der Mailcow existiert und andersherum.</p>
+<h3 id="allgemeine-probleme">Allgemeine Probleme<a class="headerlink" href="#allgemeine-probleme" title="Permanent link">&para;</a></h3>
+<ul>
+<li>Die Validierung des Connectors von Exchange zu Ihrer Mailcow schlug fehl mit <code>550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient test@contoso.com not found by SMTP address lookup</code><br />
+<strong>Mögliche Lösung:</strong> Ihre Domäne ist nicht als "internes Relay" eingerichtet. Exchange kann daher den Empfänger nicht finden.</li>
+<li>Mails, die von der Mailcow an eine Mailbox im Internet gesendet werden, können nicht zugestellt werden. Non Delivery Report mit Fehler <code>550 5.7.64 TenantAttribution; Relay Access Denied</code><br />
+<strong>Mögliche Lösung:</strong> Die Authentifizierungsmethode ist fehlgeschlagen. Stellen Sie sicher, dass der Betreff des Zertifikats mit einer akzeptierten Domäne in Exchange übereinstimmt. Versuchen Sie stattdessen die Authentifizierung über eine statische IP.</li>

+  <h1>Gitea</h1>
+
+<p>Mit der Fähigkeit von Gitea, sich über SMTP zu authentifizieren, ist es trivial, es mit mailcow zu integrieren. Es sind nur wenige Änderungen erforderlich:</p>
+<p>1. Öffnen Sie <code>docker-compose.override.yml</code> und fügen Sie Gitea hinzu:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+        gitea-mailcow:
+            image: gitea/gitea:1
+            volumes:
+                - ./data/gitea:/data
+            networks:
+                mailcow-network:
+                    aliases:
+                        - gitea
+            ports:
+                - &quot;${GITEA_SSH_PORT:-127.0.0.1:4000}:22&quot;
+</code></pre></div>
+<p>2. Erstellen Sie <code>data/conf/nginx/site.gitea.custom</code>, fügen Sie folgendes hinzu:
+<div class="highlight"><pre><span></span><code>location /gitea/ {
+        proxy_pass http://gitea:3000/;
+}
+</code></pre></div></p>
+<p>3. Öffne <code>mailcow.conf</code> und definiere den Port Bind, den Gitea für SSH verwenden soll. Beispiel:</p>
+<div class="highlight"><pre><span></span><code>GITEA_SSH_PORT=127.0.0.1:4000
+</code></pre></div>
+<p>5. Führen Sie <code>docker-compose up -d</code> aus, um den Gitea-Container hochzufahren und führen Sie anschließend <code>docker-compose restart nginx-mailcow</code> aus.</p>
+<p>6. Wenn Sie mailcow zu https gezwungen haben, führen Sie Schritt 9 aus und starten Sie gitea mit <code>docker-compose restart gitea-mailcow</code> neu. Fahren Sie mit Schritt 7 fort (Denken Sie daran, https anstelle von http zu verwenden, <code>https://mx.example.org/gitea/</code> </p>
+<p>7. Öffnen Sie <code>http://${MAILCOW_HOSTNAME}/gitea/</code>, zum Beispiel <code>http://mx.example.org/gitea/</code>. Für die Datenbankdetails stellen Sie <code>mysql</code> als Datenbankhost ein. Verwenden Sie den in mailcow.conf gefundenen Wert von DBNAME als Datenbankname, DBUSER als Datenbankbenutzer und DBPASS als Datenbankpasswort.</p>
+<p>8. Sobald die Installation abgeschlossen ist, loggen Sie sich als Administrator ein und setzen Sie "Einstellungen" -&gt; "Autorisierung" -&gt; "SMTP aktivieren". SMTP-Host sollte <code>postfix</code> mit Port <code>587</code> sein, setzen Sie <code>Skip TLS Verify</code>, da wir ein nicht gelistetes SAN verwenden ("postfix" ist höchstwahrscheinlich nicht Teil Ihres Zertifikats).</p>
+<p>9. Erstellen Sie <code>data/gitea/gitea/conf/app.ini</code> und setzen Sie die folgenden Werte. Sie können <a href="https://docs.gitea.io/en-us/config-cheat-sheet/">gitea cheat sheet, leider bisher nur in Englisch verfügbar</a> für deren Bedeutung und andere mögliche Werte konsultieren.</p>
+<div class="highlight"><pre><span></span><code>[server]
+SSH_LISTEN_PORT = 22
+# Für GITEA_SSH_PORT=127.0.0.1:4000 in mailcow.conf, setzen:
+SSH_DOMAIN = 127.0.0.1
+SSH_PORT = 4000
+# Für MAILCOW_HOSTNAME=mx.example.org in mailcow.conf (und Standard-Ports für HTTPS), setzen:
+ROOT_URL = https://mx.example.org/gitea/
+</code></pre></div>
+<p>10. Starten Sie gitea neu mit <code>docker-compose restart gitea-mailcow</code>. Ihre Nutzer sollten in der Lage sein, sich mit von mailcow verwalteten Konten anzumelden.</p>

+  <h1>Gogs</h1>
+
+<p>Mit Gogs' Fähigkeit, sich über SMTP zu authentifizieren, ist es einfach, es mit mailcow zu verbinden. Es sind nur wenige Änderungen erforderlich:</p>
+<p>1. Öffne <code>docker-compose.override.yml</code> und füge Gogs hinzu:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+    gogs-mailcow:
+      image: gogs/gogs
+      volumes:
+        - ./data/gogs:/data
+      networks:
+        mailcow-network:
+          aliases:
+            - gogs
+      ports:
+        - &quot;${GOGS_SSH_PORT:-127.0.0.1:4000}:22&quot;
+</code></pre></div>
+<p>2. Erstelle <code>data/conf/nginx/site.gogs.custom</code>, füge hinzu:
+<div class="highlight"><pre><span></span><code>location /gogs/ {
+    proxy_pass http://gogs:3000/;
+}
+</code></pre></div></p>
+<p>3. Öffne <code>mailcow.conf</code> und definiere die Bindung, die Gogs für SSH verwenden soll. Beispiel:</p>
+<div class="highlight"><pre><span></span><code>GOGS_SSH_PORT=127.0.0.1:4000
+</code></pre></div>
+<p>5. Führen Sie <code>docker-compose up -d</code> aus, um den Gogs-Container hochzufahren und führen Sie anschließend <code>docker-compose restart nginx-mailcow</code> aus.</p>
+<p>6. Öffnen Sie <code>http://${MAILCOW_HOSTNAME}/gogs/</code>, zum Beispiel <code>http://mx.example.org/gogs/</code>. Für Datenbank-Details setzen Sie <code>mysql</code> als Datenbank-Host. Verwenden Sie den in mailcow.conf gefundenen Wert von DBNAME als Datenbankname, DBUSER als Datenbankbenutzer und DBPASS als Datenbankpasswort.</p>
+<p>7. Sobald die Installation abgeschlossen ist, loggen Sie sich als Administrator ein und setzen Sie "Einstellungen" -&gt; "Autorisierung" -&gt; "SMTP aktivieren". SMTP-Host sollte <code>postfix</code> mit Port <code>587</code> sein, setzen Sie <code>Skip TLS Verify</code>, da wir ein nicht gelistetes SAN verwenden ("postfix" ist höchstwahrscheinlich nicht Teil Ihres Zertifikats).</p>
+<p>8. Erstellen Sie <code>data/gogs/gogs/conf/app.ini</code> und setzen Sie die folgenden Werte. Sie können <a href="https://gogs.io/docs/advanced/configuration_cheat_sheet">Gogs cheat sheet</a> für ihre Bedeutung und andere mögliche Werte konsultieren.</p>
+<div class="highlight"><pre><span></span><code>[server]
+SSH_LISTEN_PORT = 22
+# Für GOGS_SSH_PORT=127.0.0.1:4000 in mailcow.conf, setzen:
+SSH_DOMAIN = 127.0.0.1
+SSH_PORT = 4000
+# Für MAILCOW_HOSTNAME=mx.example.org in mailcow.conf (und Standard-Ports für HTTPS), setzen:
+ROOT_URL = https://mx.example.org/gogs/
+</code></pre></div>
+<p>9. Starten Sie Gogs neu mit <code>docker-compose restart gogs-mailcow</code>. Ihre Benutzer sollten in der Lage sein, sich mit von mailcow verwalteten Konten einzuloggen.</p>

+<p>Diese Anleitung zielt darauf ab, <a href="https://github.com/mailcow/mailcow-dockerized">mailcow-dockerized</a> mit [docker-mailman] (<a href="https://github.com/maxking/docker-mailman">https://github.com/maxking/docker-mailman</a>) zu installieren und zu konfigurieren und einige nützliche Skripte bereitzustellen. Eine wesentliche Bedingung ist, dass <em>mailcow</em> und <em>Mailman</em> in ihren eigenen Installationen für unabhängige Updates erhalten bleiben.</p>
+<p>Es gibt einige Anleitungen und Projekte im Internet, aber sie sind nicht auf dem neuesten Stand und/oder unvollständig in der Dokumentation oder Konfiguration. Diese Anleitung basiert auf der Arbeit von:</p>
+<ul>
+<li><a href="https://github.com/Shadowghost/mailcow-mailman3-dockerized">mailcow-mailman3-dockerized</a> von <a href="https://github.com/Shadowghost">Shadowghost</a></li>

+<p>Der größte Teil der Konfiguration ist in <em>mailcow</em>s <a href="../../prerequisite/prerequisite-dns/">DNS Konfiguration</a> enthalten. Nachdem diese Einrichtung abgeschlossen ist, fügen Sie eine weitere Subdomain für <em>Mailman</em> hinzu, z.B. <code>lists.example.org</code>, die auf denselben Server zeigt:</p>

+<p>Das zusätzliche Volume wird von <em>Mailman</em> verwendet, um zusätzliche Konfigurationsdateien für <em>mailcow postfix</em> zu generieren. Das externe Netzwerk wird von <em>Mailman</em> erstellt und verwendet. <em>mailcow</em> benötigt es, um eingehende Listenmails an <em>Mailman</em> zu liefern.</p>
+<p>Erstellen Sie die Datei <code>/opt/mailcow-dockerized/data/conf/postfix/extra.cf</code> (z.B. mit <code>nano</code>) und fügen Sie die folgenden Zeilen hinzu:</p>

+<p>Da wir hier die <em>mailcow postfix</em> Konfiguration überschreiben, kann dieser Schritt Ihre normalen Mailtransporte unterbrechen. Überprüfen Sie die <a href="https://github.com/mailcow/mailcow-dockerized/tree/master/data/conf/postfix">originalen Konfigurationsdateien</a>, wenn sich etwas geändert hat.</p>
+<h4 id="ssl-zertifikate">SSL-Zertifikate<a class="headerlink" href="#ssl-zertifikate" title="Permanent link">&para;</a></h4>
+<p>Da wir <em>mailcow</em> als Proxy verwenden, müssen wir die SSL-Zertifikate in die <em>mailcow</em>-Dateistruktur kopieren. Diese Aufgabe wird das Skript <a href="https://github.com/g4rf/dockerized-mailcow-mailman/tree/master/scripts/renew-ssl.sh">renew-ssl.sh</a> für uns erledigen:</p>
+<ul>
+<li>Kopieren Sie die Datei nach <code>/opt/mailcow-dockerized</code></li>
+<li>Ändere <strong>mailcow_HOSTNAME</strong> in deinen <em>mailcow</em> Hostnamen</li>
+<li>Machen Sie es ausführbar (<code>chmod a+x renew-ssl.sh</code>)</li>
+<li><strong>Noch nicht ausführen, da wir zuerst Mailman benötigen</strong></li>
+</ul>
+<p>Sie müssen einen <em>cronjob</em> erstellen, so dass neue Zertifikate kopiert werden. Führen Sie ihn als <em>root</em> oder <em>sudo</em> aus:</p>
+<div class="highlight"><pre><span></span><code>crontab -e

+<p>Um das Skript jeden Tag um 5 Uhr morgens laufen zu lassen, fügen Sie hinzu:</p>

+  <h1>Mailpiler Integration</h1>
+
+<p>Dies ist eine einfache Integration von mailcow-Aliasen und dem Mailbox-Namen in mailpiler bei Verwendung von IMAP-Authentifizierung.</p>
+<p><strong>Disclaimer</strong>: Dies wird weder offiziell vom mailcow-Projekt noch von seinen Mitwirkenden gepflegt oder unterstützt. Es wird keine Garantie oder Unterstützung angeboten, jedoch steht es Ihnen frei, Themen auf GitHub zu öffnen, um einen Fehler zu melden oder weitere Ideen zu liefern. <a href="https://github.com/patschi/mailpiler-mailcow-integration">GitHub Repo kann hier gefunden werden</a>.</p>

+<p>Die Unterstützung für Domain Wildcards wurde in Piler 1.3.10 implementiert, das am 03.01.2021 veröffentlicht wurde. Frühere Versionen funktionieren grundsätzlich, aber nach dem Einloggen sehen Sie keine E-Mails, die von oder an den Domain-Alias gesendet werden. (z.B. wenn @example.com ein Alias für <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#97;&#100;&#109;&#105;&#110;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#99;&#111;&#109;">&#97;&#100;&#109;&#105;&#110;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#99;&#111;&#109;</a> ist)</p>

+<h2 id="das-zu-losende-problem">Das zu lösende Problem<a class="headerlink" href="#das-zu-losende-problem" title="Permanent link">&para;</a></h2>
+<p>mailpiler bietet die Authentifizierung auf Basis von IMAP an, zum Beispiel:</p>
+<div class="highlight"><pre><span></span><code><span class="x">$config[&#39;ENABLE_IMAP_AUTH&#39;] = 1;</span>
+<span class="x">$config[&#39;IMAP_HOST&#39;] = &#39;mail.example.com&#39;;</span>
+<span class="x">$config[&#39;IMAP_PORT&#39;] = 993;</span>
+<span class="x">$config[&#39;IMAP_SSL&#39;] = true;</span>
+</code></pre></div>
+<ul>
+<li>Wenn Sie sich also mit <code>patrik@example.com</code> anmelden, sehen Sie nur zugestellte E-Mails, die von oder an diese spezielle E-Mail-Adresse gesendet wurden.</li>
+<li>Wenn zusätzliche Aliase in mailcow definiert werden, wie z.B. <code>team@example.com</code>, werden Sie keine Emails sehen, die an oder von dieser Email-Adresse gesendet wurden, auch wenn Sie ein Empfänger von Emails sind, die an diese Alias-Adresse gesendet wurden.</li>
+</ul>
+<p>Indem wir uns in den Authentifizierungsprozess von mailpiler einklinken, sind wir in der Lage, die erforderlichen Daten über die mailcow API während des Logins zu erhalten. Dies löst API-Anfragen an die mailcow-API aus (die einen Nur-Lese-API-Zugang erfordern), um die Aliase auszulesen, an denen Ihre E-Mail-Adresse teilnimmt, und auch den "Namen" des Postfachs, der angegeben wurde, um ihn nach dem Login oben rechts in mailpiler anzuzeigen.</p>
+<p>Zugelassene E-Mail-Adressen können in den Mailpiler-Einstellungen oben rechts nach dem Einloggen eingesehen werden.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Dies wird nur einmal während des Authentifizierungsprozesses abgefragt. Die autorisierten Aliase und der Realname sind für die gesamte Dauer der Benutzersitzung gültig, da mailpiler sie in den Sitzungsdaten setzt. Wird ein Benutzer aus einem bestimmten Alias entfernt, so wird dies erst nach dem nächsten Login wirksam.</p>

+<p class="admonition-title">Warning</p>
+<p>Da mailpiler sich gegenüber mailcow, unserem IMAP-Server, authentifiziert, können fehlgeschlagene Logins von Nutzern oder Bots eine Sperre für Ihre mailpiler-Instanz auslösen. Daher sollten Sie in Erwägung ziehen, die IP-Adresse der mailpiler-Instanz innerhalb von mailcow auf eine Whitelist zu setzen: <code>Konfiguration &amp; Details - Konfiguration - Fail2ban-Parameter - Whitelisted networks/hosts</code>.</p>

+<ol>
+<li>
+<p>Setzen Sie die benutzerdefinierte Abfragefunktion von mailpiler und fügen Sie diese an <code>/usr/local/etc/piler/config-site.php</code> an:</p>
+<div class="highlight"><pre><span></span><code><span class="x">$config[&#39;MAILCOW_API_KEY&#39;] = &#39;YOUR_READONLY_API_KEY&#39;;</span>
+<span class="x">$config[&#39;MAILCOW_SET_REALNAME&#39;] = true; // wenn nicht angegeben, dann ist der Standardwert false</span>
+<span class="x">$config[&#39;CUSTOM_EMAIL_QUERY_FUNCTION&#39;] = &#39;query_mailcow_for_email_access&#39;;</span>
+<span class="x">include(&#39;auth-mailcow.php&#39;);</span>
+</code></pre></div>
+<p>Sie können auch den mailcow-Hostnamen ändern, falls erforderlich:
+<div class="highlight"><pre><span></span><code><span class="x">$config[&#39;MAILCOW_HOST&#39;] = &#39;mail.domain.tld&#39;; // standardmäßig $config[&#39;IMAP_HOST&#39;]</span>
+</code></pre></div></p>
+</li>
+<li>
+<p>Laden Sie die PHP-Datei mit den Funktionen aus dem <a href="https://github.com/patschi/mailpiler-mailcow-integration">GitHub Repo</a> herunter:</p>
+<div class="highlight"><pre><span></span><code>curl -o /usr/local/etc/piler/auth-mailcow.php https://raw.githubusercontent.com/patschi/mailpiler-mailcow-integration/master/auth-mailcow.php
+</code></pre></div>
+</li>
+<li>
+<p>Erledigt!</p>
+</li>
+</ol>
+<p>Stellen Sie sicher, dass Sie sich erneut mit Ihren IMAP-Zugangsdaten anmelden, damit die Änderungen wirksam werden.</p>
+<p>Wenn es nicht funktioniert, ist höchstwahrscheinlich etwas mit der API-Abfrage selbst nicht in Ordnung. Versuchen Sie eine Fehlersuche, indem Sie manuelle API-Anfragen an die API senden. (Tipp: Öffnen Sie <code>https://mail.domain.tld/api</code> auf Ihrer Instanz)</p>

+<p>Nextcloud kann mit dem <a href="https://github.com/mailcow/mailcow-dockerized/raw/master/helper-scripts/nextcloud.sh">helper script</a>, das in mailcow enthalten ist, eingerichtet (Parameter <code>-i</code>) und entfernt (Parameter <code>-p</code>) werden. Um Nextcloud zu installieren, navigieren Sie einfach zu Ihrem mailcow-dockerized Root-Ordner und führen Sie das Helper-Skript wie folgt aus:</p>
+<p><code>./helper-scripts/nextcloud.sh -i</code></p>
+<p>Für den Fall, dass Sie das Passwort (z.B. für admin) vergessen haben und kein neues anfordern können [über den Passwort-Reset-Link auf dem Login-Bildschirm] (<a href="https://docs.nextcloud.com/server/20/admin_manual/configuration_user/reset_admin_password.html?highlight=reset">https://docs.nextcloud.com/server/20/admin_manual/configuration_user/reset_admin_password.html?highlight=reset</a>), können Sie durch den Aufruf des Helper-Skripts mit <code>-r</code> als Parameter ein neues Passwort setzen. Verwenden Sie diese Option nur, wenn Ihre Nextcloud nicht so konfiguriert ist, dass sie mailcow zur Authentifizierung verwendet, wie im nächsten Abschnitt beschrieben.</p>
+<h2 id="konfigurieren-sie-nextcloud-um-mailcow-fur-die-authentifizierung-zu-verwenden">Konfigurieren Sie Nextcloud, um mailcow für die Authentifizierung zu verwenden<a class="headerlink" href="#konfigurieren-sie-nextcloud-um-mailcow-fur-die-authentifizierung-zu-verwenden" title="Permanent link">&para;</a></h2>
+<p>Im Folgenden wird beschrieben, wie die Authentifizierung über mailcow unter Verwendung des OAuth2-Protokolls eingerichtet wird. Wir nehmen nur an, dass Sie Nextcloud bereits unter <em>cloud.example.com</em> eingerichtet haben und dass Ihre mailcow unter <em>mail.example.com</em> läuft. Es spielt keine Rolle, wenn Ihre Nextcloud auf einem anderen Server läuft, Sie können immer noch mailcow für die Authentifizierung verwenden.</p>
+<p>1. Melden Sie sich bei mailcow als Administrator an.</p>
+<p>2. Scrollen Sie nach unten zu <em>OAuth2 Apps</em> und klicken Sie auf die Schaltfläche <em>Hinzufügen</em>. Geben Sie die Redirect URI als <code>https://cloud.example.com/index.php/apps/sociallogin/custom_oauth2/Mailcow</code> an und klicken Sie auf <em>Hinzufügen</em>. Speichern Sie die Client-ID und das Geheimnis für später.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Einige Installationen, einschließlich derer, die mit dem Helper-Skript von mailcow eingerichtet wurden, müssen index.php/ aus der URL entfernen, um einen erfolgreichen Redirect zu erhalten: <code>https://cloud.example.com/apps/sociallogin/custom_oauth2/Mailcow</code></p>
+</div>
+<p>3. Melden Sie sich bei Nextcloud als Administrator an.</p>
+<p>4. Klicken Sie auf die Schaltfläche in der oberen rechten Ecke und wählen Sie <em>Apps</em>. Klicken Sie auf die Schaltfläche "Suchen" in der Symbolleiste, suchen Sie nach dem Plugin <a href="https://apps.nextcloud.com/apps/sociallogin"><em>Social Login</em></a> und klicken Sie daneben auf <em>Herunterladen und aktivieren</em>.</p>
+<p>5. Klicken Sie auf die Schaltfläche in der oberen rechten Ecke und wählen Sie <em>Einstellungen</em>. Scrollen Sie zum Abschnitt <em>Administration</em> auf der linken Seite und klicken Sie auf <em>Social Login</em>.</p>
+<p>6. Entfernen Sie das Häkchen bei den folgenden Punkten:</p>
+<ul>
+<li>"Automatische Erstellung neuer Benutzer deaktivieren"</li>
+<li>"Benutzern erlauben, soziale Logins mit ihren Konten zu verbinden".</li>
+<li>"Nicht verfügbare Benutzergruppen bei der Anmeldung nicht entfernen"</li>
+<li>"Gruppen automatisch erstellen, wenn sie nicht vorhanden sind"</li>
+<li>"Anmeldung für Benutzer ohne zugeordnete Gruppen einschränken".</li>
+</ul>
+<p>7. Überprüfen Sie die folgenden Punkte:</p>
+<ul>
+<li>"Die Erstellung eines Kontos verhindern, wenn die E-Mail-Adresse in einem anderen Konto existiert"</li>
+<li>"Benutzerprofil bei jeder Anmeldung aktualisieren"</li>
+<li>"Benachrichtigung der Administratoren über neue Benutzer deaktivieren".</li>
+</ul>
+<p>Klicken Sie auf die Schaltfläche <em>Speichern</em>.</p>
+<p>8. Scrollen Sie nach unten zu <em>Custom OAuth2</em> und klicken Sie auf die Schaltfläche <em>+</em>.
+9. Konfigurieren Sie die Parameter wie folgt:</p>
+<ul>
+<li>Interner Name: <code>Mailcow</code></li>
+<li>Titel: <code>Mailcow</code></li>
+<li>API Basis-URL: <code>https://mail.example.com</code></li>
+<li>Autorisierungs-URL: <code>https://mail.example.com/oauth/authorize</code></li>
+<li>Token-URL: <code>https://mail.example.com/oauth/token</code></li>
+<li>Profil-URL: <code>https://mail.example.com/oauth/profile</code></li>
+<li>Abmelde-URL: (leer lassen)</li>
+<li>Kunden-ID: (die Sie in Schritt 1 erhalten haben)</li>
+<li>Client Secret: (was Sie in Schritt 1 erhalten haben)</li>
+<li>Bereich: <code>Profil</code></li>
+</ul>
+<p>Klicken Sie auf die Schaltfläche <em>Speichern</em> ganz unten auf der Seite.</p>
+<hr />
+<p>Wenn Sie bisher Nextcloud mit mailcow-Authentifizierung über user_external/IMAP verwendet haben, müssen Sie einige zusätzliche Schritte durchführen, um Ihre bestehenden Benutzerkonten mit OAuth2 zu verknüpfen.</p>
+<p>1. Klicken Sie auf die Schaltfläche in der oberen rechten Ecke und wählen Sie <em>Apps</em>. Scrollen Sie nach unten zur App <em>Externe Benutzerauthentifizierung</em> und klicken Sie daneben auf <em>Entfernen</em>.
+2. Führen Sie die folgenden Abfragen in Ihrer Nextcloud-Datenbank aus (wenn Sie Nextcloud mit dem Skript von mailcow einrichten, können Sie <code>source mailcow.conf &amp;&amp; docker-compose exec mysql-mailcow mysql -u$DBUSER -p$DBPASS $DBNAME</code> ausführen):
+<div class="highlight"><pre><span></span><code>INSERT INTO nc_users (uid, uid_lower) SELECT DISTINCT uid, LOWER(uid) FROM nc_users_external;
+INSERT INTO nc_sociallogin_connect (uid, identifier) SELECT DISTINCT uid, CONCAT(&quot;Mailcow-&quot;, uid) FROM nc_users_external;
+</code></pre></div></p>
+<hr />
+<p>Wenn Sie Nextcloud bisher ohne mailcow-Authentifizierung, aber mit den gleichen Benutzernamen wie mailcow genutzt haben, können Sie Ihre bestehenden Benutzerkonten auch mit OAuth2 verknüpfen.</p>
+<p>1. Führen Sie die folgenden Abfragen in Ihrer Nextcloud-Datenbank aus (wenn Sie Nextcloud mit dem Skript von mailcow einrichten, können Sie <code>source mailcow.conf &amp;&amp; docker-compose exec mysql-mailcow mysql -u$DBUSER -p$DBPASS $DBNAME</code> ausführen):
+<div class="highlight"><pre><span></span><code>INSERT INTO nc_sociallogin_connect (uid, identifier) SELECT DISTINCT uid, CONCAT(&quot;Mailcow-&quot;, uid) FROM nc_users;
+</code></pre></div></p>

+<p>Die Nextcloud-Instanz kann einfach mit dem Web-Update-Mechanismus aktualisiert werden. Bei größeren Updates können nach dem Update weitere Änderungen vorgenommen werden. Nachdem die Nextcloud-Instanz geprüft wurde, werden Probleme angezeigt. Dies können z.B. fehlende Indizes in der DB oder ähnliches sein.
+Es wird angezeigt, welche Befehle ausgeführt werden müssen, diese müssen im php-fpm-mailcow Container platziert werden.</p>
+<p>Führen Sie z.B. folgenden Befehl aus, um die fehlenden Indizes hinzuzufügen
+<code>docker exec -it -u www-data $(docker ps -f name=php-fpm-mailcow -q) bash -c "php /web/nextcloud/occ db:add-missing-indices"</code></p>

+<p>Es kann vorkommen, dass Sie die Nextcloud-Instanz von Ihrem Netzwerk aus nicht erreichen können. Dies kann daran liegen, dass der Eintrag Ihres Subnetzes im Array 'trusted_proxies' fehlt. Sie können Änderungen in der Nextcloud config.php in <code>data/web/nextcloud/config/*</code> vornehmen.</p>
+<div class="highlight"><pre><span></span><code>&#39;trusted_proxies&#39; =&gt;
+  array (

+    2 =&gt; &#39;NewSubnet/24&#39;,
+  ),
+</code></pre></div>
+<p>Nachdem die Änderungen vorgenommen wurden, muss der nginx-Container neu gestartet werden.
+<code>docker-compose restart nginx-mailcow</code></p>

+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+    portainer-mailcow:
+      image: portainer/portainer-ce
+      volumes:
+        - /var/run/docker.sock:/var/run/docker.sock
+        - ./data/conf/portainer:/data
+      restart: always
+      dns:
+        - 172.22.1.254
+      dns_search: mailcow-network
+      networks:
+        mailcow-network:
+          aliases:
+            - portainer
+</code></pre></div>
+2a. Erstelle <code>data/conf/nginx/portainer.conf</code>:
+<div class="highlight"><pre><span></span><code>upstream portainer {
+  server portainer-mailcow:9000;
+}
+
+map $http_upgrade $connection_upgrade {
+  default upgrade;
+  &#39;&#39; close;
+}
+</code></pre></div></p>
+<p>2b. Fügen Sie einen neuen Standort für die Standard-Mailcow-Site ein, indem Sie die Datei <code>data/conf/nginx/site.portainer.custom</code> erstellen:
+<div class="highlight"><pre><span></span><code>  location /portainer/ {
+    proxy_http_version 1.1;
+    proxy_set_header Host              $http_host;   # required for docker client&#39;s sake
+    proxy_set_header X-Real-IP         $remote_addr; # pass on real client&#39;s IP
+    proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_read_timeout                 900;
+
+    proxy_set_header Connection &quot;&quot;;
+    proxy_buffers 32 4k;
+    proxy_pass http://portainer/;
+  }
+
+  location /portainer/api/websocket/ {
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection $connection_upgrade;
+    proxy_pass http://portainer/api/websocket/;
+  }
+</code></pre></div></p>
+<p>3. Übernehmen Sie Ihre Änderungen:
+<div class="highlight"><pre><span></span><code>docker-compose up -d &amp;&amp; docker-compose restart nginx-mailcow
+</code></pre></div></p>
+<p>Nun können Sie einfach zu https://${MAILCOW_HOSTNAME}/portainer/ navigieren, um Ihre Portainer-Container-Überwachungsseite anzuzeigen. Sie werden dann aufgefordert, ein neues Passwort für den <strong>admin</strong> Account anzugeben. Nachdem Sie Ihr Passwort eingegeben haben, können Sie sich mit der Portainer UI verbinden.</p>

+  <h1>Admin-Anmeldung bei SOGo</h1>
+
+<p>Dies ist eine experimentelle Funktion, die es Admins und Domänenadmins erlaubt, sich direkt als Mailbox-Benutzer bei SOGo anzumelden, ohne das Passwort des Benutzers zu kennen.
+Dazu wird ein zusätzlicher Link zu SOGo in der Mailbox-Liste (mailcow UI) angezeigt.</p>
+<p>Auch mehrere gleichzeitige Admin-Logins auf verschiedene Postfächer sind mit dieser Funktion möglich.</p>
+<h2 id="aktivieren-der-funktion">Aktivieren der Funktion<a class="headerlink" href="#aktivieren-der-funktion" title="Permanent link">&para;</a></h2>
+<p>Die Funktion ist standardmäßig deaktiviert. Es kann in der <code>mailcow.conf</code> durch Setzen aktiviert werden:
+<div class="highlight"><pre><span></span><code>ALLOW_ADMIN_EMAIL_LOGIN=y
+</code></pre></div>
+und die betroffenen Container neu erstellen mit
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div></p>
+<h2 id="nachteile-bei-aktivierung">Nachteile bei Aktivierung<a class="headerlink" href="#nachteile-bei-aktivierung" title="Permanent link">&para;</a></h2>
+<ul>
+<li>Jeder SOGo-Seiten-Load und jede Active-Sync-Anfrage verursacht eine zusätzliche Ausführung eines internen PHP-Skripts.
+Dies kann die Ladezeiten von SOGo / EAS beeinträchtigen.
+In den meisten Fällen sollte dies nicht spürbar sein, aber Sie sollten es im Hinterkopf behalten, wenn Sie Performance-Probleme haben.</li>
+<li>SOGo zeigt keinen Logout-Link für Admin-Logins an, um sich normal anzumelden, muss man sich von der mailcow UI abmelden, so dass die PHP-Sitzung zerstört wird.</li>
+<li>Das Abonnieren des Kalenders oder Adressbuchs eines anderen Nutzers, während man als Admin eingeloggt ist, funktioniert nicht. Ebenso wenig funktioniert das Einladen anderer Nutzer zu Kalender-Events. Die Seite wird neu geladen, wenn diese Dinge versucht werden.</li>
+</ul>
+<h2 id="technische-details">Technische Details<a class="headerlink" href="#technische-details" title="Permanent link">&para;</a></h2>
+<p>Die Option SOGoTrustProxyAuthentication ist auf YES gesetzt, so dass SOGo dem x-webobjects-remote-user-Header vertraut.</p>
+<p>Dovecot erhält ein zufälliges Master-Passwort, das für alle Mailboxen gültig ist, wenn es vom SOGo-Container verwendet wird.</p>
+<p>Ein Klick auf den SOGo-Button in der Mailbox-Liste öffnet die Datei sogo-auth.php, die Berechtigungen prüft, Session-Variablen setzt und auf die SOGo-Mailbox umleitet.</p>
+<p>Jede SOGo, CardDAV, CalDAV und EAS http-Anfrage verursacht einen zusätzlichen, nginx-internen auth_request-Aufruf an sogo-auth.php mit folgendem Verhalten:</p>
+<ul>
+<li>
+<p>Wenn ein basic_auth-Header vorhanden ist, wird das Skript die Anmeldedaten anstelle von SOGo validieren und die folgenden Header bereitstellen:
+<code>x-webobjects-remote-user</code>, <code>Authorization</code> und <code>x-webobjects-auth-type</code>.</p>
+</li>
+<li>
+<p>Wenn kein basic_auth-Header vorhanden ist, wird das Skript nach einer aktiven Mailcow-Admin-Sitzung für den angeforderten E-Mail-Benutzer suchen und die gleichen Header bereitstellen, aber mit dem Dovecot-Master-Passwort, das im <code>Authorization</code>-Header verwendet wird.</p>
+</li>
+<li>
+<p>Wenn beides fehlschlägt, werden die Header leer gesetzt, was SOGo dazu bringt, seine Standard-Authentifizierungsmethoden zu verwenden.</p>
+</li>
+</ul>
+<p>Alle diese Optionen/Verhaltensweisen sind deaktiviert, wenn die Option <code>ALLOW_ADMIN_EMAIL_LOGIN</code> in der Konfiguration nicht aktiviert ist.</p>

+<h2 id="mail-kommt-in-einer-schleife-zu-sich-selbst-zuruck">Mail kommt in einer Schleife zu sich selbst zurück.<a class="headerlink" href="#mail-kommt-in-einer-schleife-zu-sich-selbst-zuruck" title="Permanent link">&para;</a></h2>
+<p>Bitte überprüfen Sie in Ihrer mailcow UI, ob Sie die Domain als <strong>Backup MX</strong> eingestellt haben:
+<img alt="Überprüfen Sie Ihre MX-Backup-Einstellungen" src="../../assets/images/troubleshooting/mailcow-backupmx.png" /></p>
+<h2 id="ich-kann-mails-empfangen-aber-nicht-senden">Ich kann Mails empfangen, aber nicht senden<a class="headerlink" href="#ich-kann-mails-empfangen-aber-nicht-senden" title="Permanent link">&para;</a></h2>
+<p>Es gibt viele Gründe, die Sie daran hindern können, Mails zu versenden:</p>
+<ul>
+<li>Prüfen Sie, ob Ihre IP-Adresse auf einer schwarzen Liste steht. Sie können <a href="http://www.dnsbl.info/">dnsbl.info</a> oder einen ähnlichen Dienst verwenden, um Ihre IP-Adresse zu überprüfen.</li>
+<li>Es gibt einige ISP-Router, die Mail-Ports für nicht auf der Blacklist stehende Domains blockieren. Bitte überprüfen Sie, ob Sie Ihren Server über die Ports <code>465</code> oder <code>587</code> erreichen können:</li>
+</ul>
+<div class="highlight"><pre><span></span><code># telnet 74.125.133.27 465
+Versucht 74.125.133.27...
+Verbunden mit 74.125.133.27.
+Escape-Zeichen ist &#39;^]&#39;.

+<h2 id="meine-mails-werden-als-spam-identifiziert">Meine Mails werden als Spam identifiziert<a class="headerlink" href="#meine-mails-werden-als-spam-identifiziert" title="Permanent link">&para;</a></h2>
+<p>Bitte lesen Sie unsere <a href="../../prerequisite/prerequisite-dns/">DNS-Konfiguration</a> Anleitung.</p>
+<h2 id="docker-compose-wirft-seltsame-fehler-aus">docker-compose wirft seltsame Fehler aus.<a class="headerlink" href="#docker-compose-wirft-seltsame-fehler-aus" title="Permanent link">&para;</a></h2>
+<p>... wie:</p>
+<ul>
+<li><code>ERROR: Ungültiges Interpolationsformat ...</code></li>
+<li><code>AttributeError: 'NoneType' Objekt hat kein Attribut 'keys'</code>.</li>
+<li>ERROR: In der Datei './docker-compose.yml' hat der Dienst 'version' keine Konfigurationsoptionen.</li>
+</ul>
+<p>Wenn Sie eine oder ähnliche Meldungen erhalten, während Sie versuchen, mailcow: dockerized auszuführen, überprüfen Sie bitte, ob Sie die <strong>aktuellste</strong> Version von <strong>Docker</strong> und <strong>docker-compose</strong> haben.</p>
+<h2 id="container-xy-ist-ungesund">Container XY ist ungesund<a class="headerlink" href="#container-xy-ist-ungesund" title="Permanent link">&para;</a></h2>
+<p>Dieser Fehler versucht Ihnen mitzuteilen, dass eine der (Gesundheits-)Bedingungen für einen bestimmten Container nicht erfüllt ist. Daher kann er nicht gestartet werden. Dies kann verschiedene Gründe haben, der häufigste ist ein aktualisierter Git-Klon, aber ein altes Docker-Image oder umgekehrt.</p>
+<p>Auch eine falsch konfigurierte Firewall kann einen solchen Fehler verursachen. Die Container müssen in der Lage sein, über das Netzwerk 172.22.1.1/24 miteinander zu kommunizieren.</p>
+<p>Es könnte auch eine falsch verknüpfte Datei sein (z. B. ein SSL-Zertifikat), die den Start eines wichtigen Containers (nginx) verhindert. Prüfen Sie daher immer Ihre Protokolle, um herauszufinden, woher das Problem kommt.</p>

+<p>während Sie versuchen, mailcow: dockerized zu starten / zu installieren, stellen Sie sicher, dass Sie unseren Abschnitt über <a href="../prerequisite/prerequisite-system.de.md/#firewall-ports">prerequisites</a> befolgt haben.</p>
+<h2 id="xyz-kann-keine-verbindung-zu">XYZ kann keine Verbindung zu ...<a class="headerlink" href="#xyz-kann-keine-verbindung-zu" title="Permanent link">&para;</a></h2>
+<p>Bitte überprüfen Sie Ihre lokale Firewall!
+Docker und iptables-basierte Firewalls erstellen manchmal widersprüchliche Regeln. Deaktivieren Sie daher die Firewall auf Ihrem Host, um festzustellen, ob Ihre Verbindungsprobleme durch solche Konflikte verursacht werden. Wenn dies der Fall ist, müssen Sie manuell entsprechende Regeln in Ihrer Host-Firewall erstellen, um die erforderlichen Verbindungen zuzulassen.</p>
+<p>Wenn Sie Verbindungsprobleme von zu Hause aus haben, überprüfen Sie bitte auch die Firewall Ihres ISP-Routers, da einige von ihnen den E-Mail-Verkehr über die Ports <em>SMTP</em> (587) oder <em>SMTPS</em> (465) blockieren. Es könnte auch sein, dass Ihr ISP die Ports für <em>SUBMISSION</em> (25) blockiert.</p>
+<p>Während Linux-Benutzer aus einer Vielzahl von Tools<sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup> wählen können, um zu überprüfen, ob ein Port offen ist, steht Windows-Benutzern standardmäßig nur der PowerShell-Befehl <code>Test-NetConnection -ComputerName host -Port port</code> zur Verfügung.</p>
+<p>Um Telnet auf einem Windows nach Vista zu aktivieren, lesen Sie bitte diese <a href="https://social.technet.microsoft.com/wiki/contents/articles/910.windows-7-enabling-telnet-client.aspx">Anleitung</a> oder geben Sie den folgenden Befehl in einem Terminal <strong>mit Administratorrechten</strong> ein:</p>

Dies ist normalerweise ein bisschen viel, aber Sie können die Ausgabe mit <code>--tail=100</code> auf die letzten 100 Zeilen pro Container kürzen, oder ein <code>-f</code> hinzufügen, um die Live-Ausgabe aller Ihrer Dienste zu verfolgen.</p>
+<p>Um die Logs eines bestimmten Dienstes zu sehen, kann man <code>docker-compose logs [options] $service_name</code> verwenden</p>

+  <h1>TLS-Zertifikate zurücksetzen</h1>
+
+<p>Sollten Sie Probleme mit Ihrem Zertifikat, Schlüssel oder Let's Encrypt-Konto haben, versuchen Sie bitte, die TLS-Assets zurückzusetzen:</p>
+<div class="highlight"><pre><span></span><code>source mailcow.conf
+docker-compose down
+rm -rf data/assets/ssl
+mkdir data/assets/ssl
+openssl req -x509 -newkey rsa:4096 -keyout data/assets/ssl-example/key.pem -out data/assets/ssl-example/cert.pem -days 365 -subj &quot;/C=DE/ST=NRW/L=Willich/O=mailcow/OU=mailcow/CN=${MAILCOW_HOSTNAME}&quot; -sha256 -nodes
+cp -n -d data/assets/ssl-example/*.pem data/assets/ssl/
+docker-compose up -d
+</code></pre></div>
+<p>Dies wird mailcow stoppen, die benötigten Variablen beschaffen, ein selbstsigniertes Zertifikat erstellen und mailcow starten.</p>
+<p>Wenn Sie Let's Encrypt verwenden, sollten Sie vorsichtig sein, da Sie ein neues Konto und einen neuen Satz von Zertifikaten erstellen werden. Sie werden früher oder später auf ein Ratelimit stoßen.</p>
+<p>Bitte beachten Sie auch, dass frühere TLSA-Datensätze ungültig werden.</p>

+  <h1>Persistente Daten löschen</h1>
+
+<p>Es kann sein, dass Sie einen Satz persistenter Daten entfernen wollen, um einen Konflikt zu lösen oder um neu zu beginnen.</p>
+<p><code>mailcowdockerized</code> kann variieren und hängt von Ihrem Compose-Projektnamen ab (wenn er unverändert ist, ist <code>mailcowdockerized</code> der richtige Wert). Wenn Sie sich unsicher sind, führen Sie <code>docker volume ls</code> aus, um eine vollständige Liste zu erhalten.</p>
+<p>Löschen Sie ein einzelnes Volume:</p>
+<div class="highlight"><pre><span></span><code>docker volume rm mailcowdockerized_${VOLUME_NAME}
+</code></pre></div>
+<ul>
+<li>Entfernen Sie Volume <code>mysql-vol-1</code>, um alle MySQL-Daten zu entfernen.</li>
+<li>Entfernen Sie Volume <code>redis-vol-1</code> um alle Redis Daten zu entfernen.</li>
+<li>Volume <code>vmail-vol-1</code> entfernen, um alle Inhalte von <code>/var/vmail</code> zu entfernen, die in <code>dovecot-mailcow</code> eingebunden sind.</li>
+<li>Entfernen Sie das Volume <code>rspamd-vol-1</code>, um alle Rspamd-Daten zu entfernen.</li>
+<li>Entfernen Sie Volume <code>crypt-vol-1</code>, um alle Crypto-Daten zu entfernen. Dies wird <strong>alle Mails</strong> unlesbar machen.</li>
+</ul>
+<p>Alternativ dazu wird die Ausführung von <code>docker-compose down -v</code> <strong>alle mailcow: dockerized volumes</strong> zerstören und alle zugehörigen Container und Netzwerke löschen.</p>

+  <h1>Fortgeschritten: Memory-Leaks in Rspamd finden</h1>
+
+<p>Eine kurze Anleitung, um einen schlecht funktionierenden Rspamd tiefgehend zu analysieren.</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow bash
+
+if ! grep -qi &#39;apt-stable-asan&#39; /etc/apt/sources.list.d/rspamd.list; then
+  sed -i &#39;s/apt-stabil/apt-stabil-asan/i&#39; /etc/apt/sources.list.d/rspamd.list
+fi
+
+apt-get update ; apt-get upgrade rspamd
+
+nano /docker-entrypoint.sh
+
+# Fügen Sie vor &quot;exec &quot;$@&quot;&quot; die folgenden Zeilen ein:
+
+export G_SLICE=always-malloc
+export ASAN_OPTIONS=new_delete_type_mismatch=0:detect_leaks=1:detect_odr_violation=0:log_path=/tmp/rspamd-asan:quarantine_size_mb=2048:malloc_context_size=8:fast_unwind_on_malloc=0
+</code></pre></div>
+<p>Starten Sie Rspamd neu: <code>docker-compose restart rspamd-mailcow</code></p>
+<p>Ihr Speicherverbrauch wird stark ansteigen, er wird auch stetig wachsen, was nicht mit einem möglichen Memory Leak zusammenhängt, nach dem Sie suchen.</p>
+<p>Lassen Sie den Container für ein paar Minuten, Stunden oder Tage laufen (es sollte die Zeit sein, die Sie normalerweise warten, bis der Memory Leak "passiert") und starten Sie ihn neu: <code>docker-compose restart rspamd-mailcow</code>.</p>
+<p>Betreten Sie nun den Container, indem Sie <code>docker-compose exec rspamd-mailcow bash</code> ausführen, wechseln Sie das Verzeichnis zu /tmp und kopieren Sie die asan-Dateien an den gewünschten Ort oder laden Sie sie über termbin.com hoch (<code>cat /tmp/rspamd-asan.* | nc termbin.com 9999</code>).</p>

+  <h1>Recover accidentally deleted data</h1>
+
+<p>So you deleted a mailbox and have no backups, he?</p>
+<p>If you noticed your mistake within a few hours, you can probably recover the users data.</p>
+<h3 id="sogo">SOGo<a class="headerlink" href="#sogo" title="Permanent link">&para;</a></h3>
+<p>We automatically create daily backups (24h interval starting from running up -d) in <code>/var/lib/docker/volumes/mailcowdockerized_sogo-userdata-backup-vol-1/_data/</code>.</p>
+<p><strong>Make sure the user you want to restore exists in your mailcow</strong>. Re-create them if they are missing.</p>
+<p>Copy the file named after the user you want to restore to <code>__MAILCOW_DIRECTORY__/data/conf/sogo</code>.</p>
+<p>1. Copy the backup: <code>cp /var/lib/docker/volumes/mailcowdockerized_sogo-userdata-backup-vol-1/_data/restoreme@example.org __MAILCOW_DIRECTORY__/data/conf/sogo</code></p>
+<p>2. Run <code>docker-compose exec -u sogo sogo-mailcow sogo-tool restore -F ALL /etc/sogo restoreme@example.org</code></p>
+<p>Run <code>sogo-tool</code> without parameters to check for possible restore options.</p>
+<p>3. Delete the copied backup by running <code>rm __MAILCOW_DIRECTORY__/data/conf/sogo</code></p>
+<p>4. Restart SOGo and Memcached: <code>docker-compose restart sogo-mailcow memcached-mailcow</code></p>
+<h3 id="mail">Mail<a class="headerlink" href="#mail" title="Permanent link">&para;</a></h3>
+<p>In case of an accidental deletion of a mailbox, you will be able to recover for (by default) 5 days. This depends on the <code>MAILDIR_GC_TIME</code> parameter in <code>mailcow.conf</code>.</p>
+<p>A deleted mailbox is copied in its encrypted form to <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/_garbage</code>.</p>
+<p>The folder inside <code>_garbage</code> follows the structure <code>[timestamp]_[domain_sanitized][user_sanitized]</code>, for example <code>1629109708_exampleorgtest</code> in case of <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#116;&#101;&#115;&#116;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#111;&#114;&#103;">&#116;&#101;&#115;&#116;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#111;&#114;&#103;</a> deleted on 1629109708.</p>
+<p>To restore make sure you are actually restoring to the same mailcow it was deleted from or you use the same encryption keys in <code>crypt-vol-1</code>.</p>
+<p><strong>Make sure the user you want to restore exists in your mailcow</strong>. Re-create them if they are missing.</p>
+<p>Copy the folders from <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/_garbage/[timestamp]_[domain_sanitized][user_sanitized]</code> back to <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/[domain]/[user]</code> and resync the folder and recalc the quota:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm force-resync -u restoreme@example.net &#39;*&#39;
+docker-compose exec dovecot-mailcow doveadm quota recalc -u restoreme@example.net

+<p>You can use the provided script <code>helper-scripts/backup_and_restore.sh</code> to backup mailcow automatically.</p>
+<p>Please do not copy this script to another location.</p>
+<p>To run a backup, write "backup" as first parameter and either one or more components to backup as following parameters.
+You can also use "all" as second parameter to backup all components. Append <code>--delete-days n</code> to delete backups older than n days.</p>
+<div class="highlight"><pre><span></span><code># Syntax:
+# ./helper-scripts/backup_and_restore.sh backup (vmail|crypt|redis|rspamd|postfix|mysql|all|--delete-days)
+
+# Backup all, delete backups older than 3 days
+./helper-scripts/backup_and_restore.sh backup all --delete-days 3
+
+# Backup vmail, crypt and mysql data, delete backups older than 30 days
+./helper-scripts/backup_and_restore.sh backup vmail crypt mysql --delete-days 30
+
+# Backup vmail
+./helper-scripts/backup_and_restore.sh backup vmail
+</code></pre></div>
+<p>The script will ask you for a backup location. Inside of this location it will create folders in the format "mailcow_DATE".
+You should not rename those folders to not break the restore process.</p>
+<p>To run a backup unattended, define MAILCOW_BACKUP_LOCATION as environment variable before starting the script:</p>
+<div class="highlight"><pre><span></span><code>MAILCOW_BACKUP_LOCATION=/opt/backup /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup all
+</code></pre></div>
+<h4 id="cronjob">Cronjob<a class="headerlink" href="#cronjob" title="Permanent link">&para;</a></h4>
+<p>You can run the backup script regularly via cronjob. Make sure <code>BACKUP_LOCATION</code> exists:</p>
+<div class="highlight"><pre><span></span><code>5 4 * * * cd /opt/mailcow-dockerized/; MAILCOW_BACKUP_LOCATION=/mnt/mailcow_backups /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup mysql crypt redis --delete-days 3
+</code></pre></div>
+<p>Per default cron sends the full result of each backup operation by email. If you want cron to only mail on error (non-zero exit code) you may want to use the following snippet. Pathes need to be modified according to your setup (this script is a user contribution).</p>
+<p>This following script may be placed in <code>/etc/cron.daily/mailcow-backup</code> - do not forget to mark it as executable via <code>chmod +x</code>:</p>
+<div class="highlight"><pre><span></span><code>#!/bin/sh
+
+# Backup mailcow data
+# https://mailcow.github.io/mailcow-dockerized-docs/b_n_r_backup/
+
+set -e
+
+OUT=&quot;$(mktemp)&quot;

+RESULT=$?
+
+if [ $RESULT -ne 0 ]
+    then
+            echo &quot;${SCRIPT} ${PARAMETERS} ${OPTIONS} encounters an error:&quot;
+            echo &quot;RESULT=$RESULT&quot;
+            echo &quot;STDOUT / STDERR:&quot;
+            cat &quot;$OUT&quot;
+fi

+<p>Create the destination directory for mailcows helper script:
+<div class="highlight"><pre><span></span><code>mkdir -p /external_share/backups/backup_script
+</code></pre></div></p>
+<p>Create cronjobs:
+<div class="highlight"><pre><span></span><code>25 1 * * * rsync -aH --delete /opt/mailcow-dockerized /external_share/backups/mailcow-dockerized
+40 2 * * * rsync -aH --delete /var/lib/docker/volumes /external_share/backups/var_lib_docker_volumes
+5 4 * * * cd /opt/mailcow-dockerized/; BACKUP_LOCATION=/external_share/backups/backup_script /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup mysql crypt redis --delete-days 3
+# If you want to, use the acl util to backup permissions of some/all folders/files: getfacl -Rn /path
+</code></pre></div></p>
+<p>On the destination (in this case <code>/external_share/backups</code>) you may want to have snapshot capabilities (ZFS, Btrfs etc.). Snapshot daily and keep for n days for a consistent backup.
+Do <strong>not</strong> rsync to a Samba share, you need to keep the correct permissions!</p>
+<p>To restore you'd simply need to run rsync the other way round and restart Docker to re-read the volumes. Run <code>docker-compose pull</code> and <code>docker-compose up -d</code>.</p>
+<p>If you are lucky Redis and MariaDB can automatically fix the inconsistent databases (if they <em>are</em> inconsistent).
+In case of a corrupted database you'd need to use the helper script to restore the inconsistent elements. If a restore fails, try to extract the backups and copy the files back manually. Keep the file permissions!</p>

+<p>mailcow offers an easy way to create a consistent copy of itself to be rsync'ed to a remote location without downtime.</p>
+<p>This may also be used to transfer your mailcow to a new server.</p>
+<h2 id="you-should-know">You should know<a class="headerlink" href="#you-should-know" title="Permanent link">&para;</a></h2>
+<p>The provided script will work on default installations.</p>
+<p>It may break when you use unsupported volume overrides. We don't support that and we will not include hacks to support that. Please run and maintain a fork if you plan to keep your changes.</p>
+<p>The script will use <strong>the same pathes</strong> as your default mailcow installation. That is the mailcow base directory - for most users <code>/opt/mailcow-dockerized</code> - as well as the mountpoints.</p>
+<p>To find the pathes of your source volumes we use <code>docker inspect</code> and read the destination directory of every volume related to your mailcow compose project. This means we will also transfer volumes you may have added in a override file. Local bind mounts may or may not work.</p>
+<p>The use rsync with the <code>--delete</code> flag. The destination will be an exact copy of the source.</p>
+<p><code>mariabackup</code> is used to create a consistent copy of the SQL data directory.</p>
+<p>After rsync'ing the data we will run <code>docker-compose pull</code> and remove old image tags from the destination.</p>
+<p>Your source will not be changed at any time.</p>
+<p><strong>You may want to make sure to use the same <code>/etc/docker/daemon.json</code> on the remote target.</strong></p>
+<p>You should not run disk snapshots (e.g. via ZFS, LVM etc.) on the target at the very same time as this script is run.</p>
+<p>Versioning is not part of this script, we rely on the destination (snapshots or backups). You may also want to use any other tool for that.</p>
+<h2 id="prepare">Prepare<a class="headerlink" href="#prepare" title="Permanent link">&para;</a></h2>
+<p>You will need a SSH-enabled destination and a keyfile to connect to said destination. The key should not be protected by a password for the script to work unattended.</p>
+<p>In your mailcow base directory, e.g. <code>/opt/mailcow-dockerized</code> you will find a file <code>create_cold_standby.sh</code>.</p>
+<p>Edit this file and change the exported variables:</p>
+<div class="highlight"><pre><span></span><code>export REMOTE_SSH_KEY=/path/to/keyfile
+export REMOTE_SSH_PORT=22
+export REMOTE_SSH_HOST=mailcow-backup.host.name
+</code></pre></div>
+<p>The key must be owned and readable by root only.</p>
+<p>Both the source and destination require <code>rsync</code> &gt;= v3.1.0.
+The destination must have Docker and docker-compose <strong>v1</strong> available.</p>
+<p>The script will detect errors automatically and exit.</p>
+<p>You may want to test the connection by running <code>ssh mailcow-backup.host.name -p22 -i /path/to/keyfile</code>.</p>
+<h2 id="backup-and-refresh-the-cold-standby">Backup and refresh the cold-standby<a class="headerlink" href="#backup-and-refresh-the-cold-standby" title="Permanent link">&para;</a></h2>
+<p>Run the first backup, this may take a while depending on the connection:</p>
+<div class="highlight"><pre><span></span><code>bash /opt/mailcow-dockerized/create_cold_standby.sh
+</code></pre></div>
+<p>That was easy, wasn't it?</p>
+<p>Updating your cold-standby is just as easy:</p>
+<div class="highlight"><pre><span></span><code>bash /opt/mailcow-dockerized/create_cold_standby.sh
+</code></pre></div>
+<p>It's the same command.</p>
+<h2 id="automated-backups-with-cron">Automated backups with cron<a class="headerlink" href="#automated-backups-with-cron" title="Permanent link">&para;</a></h2>
+<p>First make sure that the <code>cron</code> service is enabled and running:</p>
+<div class="highlight"><pre><span></span><code>systemctl enable cron.service &amp;&amp; systemctl start cron.service
+</code></pre></div>
+<p>To automate the backups to the cold-standby server you can use a cron job. To edit the cron jobs for the root user run:</p>
+<div class="highlight"><pre><span></span><code>crontab -e
+</code></pre></div>
+<p>Add the following lines to synchronize the cold standby server daily at 03:00. In this example errors of the last execution are logged into a file.</p>
+<div class="highlight"><pre><span></span><code>PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+
+0 3 * * * bash /opt/mailcow-dockerized/create_cold_standby.sh 2&gt; /var/log/mailcow-coldstandby-sync.log
+</code></pre></div>
+<p>If saved correctly, the cron job should be shown by typing:</p>
+<div class="highlight"><pre><span></span><code>crontab -l
+</code></pre></div>

+<p>On iOS, Exchange ActiveSync is also supported as an alternative to the procedure above. It has the advantage of supporting push email (i.e. you are immediately notified of incoming messages), but has some limitations, e.g. it does not support more than three email addresses per contact in your address book. Follow the steps below if you decide to use Exchange instead.</p>
+<ol>
+<li>Open the <em>Settings</em> app, tap <em>Mail</em>, tap <em>Accounts</em>, tap <em>Add Acccount</em>, select <em>Exchange</em>.</li>
+<li>Enter your email address<span class="client_variables_available"> (<code><span class="client_var_email"></span></code>)</span> and tap <em>Next</em>.</li>
+<li>Enter your password, tap <em>Next</em> again.</li>
+<li>Finally, tap <em>Save</em>.</li>

+
+  <h1>Installation</h1>
+
+<p>You need Docker (a version &gt;= <code>20.10.2</code> is required) and Docker Compose (a version <code>&lt;= 2.0</code> is required).</p>
+<p><strong>1.</strong> Learn how to install <a href="https://docs.docker.com/install/">Docker</a> and <a href="https://docs.docker.com/compose/install/">Docker Compose</a>.</p>
+<p>Quick installation for most operation systems:</p>
+<ul>
+<li>
+<p>Docker
+<div class="highlight"><pre><span></span><code>curl -sSL https://get.docker.com/ | CHANNEL=stable sh
+# After the installation process is finished, you may need to enable the service and make sure it is started (e.g. CentOS 7)
+systemctl enable --now docker
+</code></pre></div></p>
+</li>
+<li>
+<p>Docker-Compose</p>
+</li>
+</ul>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p><strong>mailcow requires the latest version of docker-compose v1.</strong> It is highly recommended to use the commands below to install <code>docker-compose</code>. Package managers (e.g. <code>apt</code>, <code>yum</code>) <strong>likely won't</strong> give you the correct version.
+<em>Note: This command downloads docker-compose from the official Docker Github repository and is a safe method. The snippet will determine the latest supported version by mailcow. In almost all cases this is the latest version available (exceptions are broken releases or major changes not yet supported by mailcow).</em></p>
+</div>
+<div class="highlight"><pre><span></span><code>curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) &gt; /usr/local/bin/docker-compose
+chmod +x /usr/local/bin/docker-compose
+</code></pre></div>
+<p>Please use the latest Docker engine available and do not use the engine that ships with your distros repository.</p>
+<p><strong>1.1.</strong> On SELinux enabled systems, e.g. CentOS 7:</p>
+<ul>
+<li>Check if "container-selinux" package is present on your system:</li>
+</ul>
+<div class="highlight"><pre><span></span><code>rpm -qa | grep container-selinux
+</code></pre></div>
+<p>If the above command returns an empty or no output, you should install it via your package manager.</p>
+<ul>
+<li>Check if docker has SELinux support enabled:</li>
+</ul>
+<div class="highlight"><pre><span></span><code>docker info | grep selinux
+</code></pre></div>
+<p>If the above command returns an empty or no output, create or edit <code>/etc/docker/daemon.json</code> and add <code>"selinux-enabled": true</code>. Example file content:</p>
+<div class="highlight"><pre><span></span><code>{
+  &quot;selinux-enabled&quot;: true
+}
+</code></pre></div>
+<p>Restart the docker daemon and verify SELinux is now enabled.</p>
+<p>This step is required to make sure mailcows volumes are properly labeled as declared in the compose file.
+If you are interested in how this works, you can check out the readme of <a href="https://github.com/containers/container-selinux">https://github.com/containers/container-selinux</a> which links to a lot of useful information on that topic.</p>
+<p><strong>2.</strong> Clone the master branch of the repository, make sure your umask equals 0022. Please clone the repository as root user and also control the stack as root. We will modify attributes - if necessary - while boostrapping the containers automatically and make sure everything is secured. The update.sh script must therefore also be run as root. It might be necessary to change ownership and other attributes of files you will otherwise not have access to. <strong>We drop permissions for every exposed application</strong> and will not run an exposed service as root! Controlling the Docker daemon as non-root user does not give you additional security. The unprivileged user will spawn the containers as root likewise. The behaviour of the stack is identical.</p>
+<div class="highlight"><pre><span></span><code>$ su
+# umask
+0022 # &lt;- Verify it is 0022
+# cd /opt
+# git clone https://github.com/mailcow/mailcow-dockerized
+# cd mailcow-dockerized
+</code></pre></div>
+<p><strong>3.</strong> Generate a configuration file. Use a FQDN (<code>host.domain.tld</code>) as hostname when asked.
+<div class="highlight"><pre><span></span><code>./generate_config.sh
+</code></pre></div></p>
+<p><strong>4.</strong> Change configuration if you want or need to.
+<div class="highlight"><pre><span></span><code>nano mailcow.conf
+</code></pre></div>
+If you plan to use a reverse proxy, you can, for example, bind HTTPS to 127.0.0.1 on port 8443 and HTTP to 127.0.0.1 on port 8080.</p>
+<p>You may need to stop an existing pre-installed MTA which blocks port 25/tcp. See <a href="../../post_installation/firststeps-local_mta/">this chapter</a> to learn how to reconfigure Postfix to run besides mailcow after a successful installation.</p>
+<p>Some updates modify mailcow.conf and add new parameters. It is hard to keep track of them in the documentation. Please check their description and, if unsure, ask at the known channels for advise.</p>
+<p><strong>4.1.</strong> Users with a MTU not equal to 1500 (e.g. OpenStack):</p>
+<p><strong>Whenever you run into trouble and strange phenomena, please check your MTU.</strong></p>
+<p>Edit <code>docker-compose.yml</code> and change the network settings according to your MTU.
+Add the new driver_opts parameter like this:
+<div class="highlight"><pre><span></span><code>networks:
+  mailcow-network:
+    ...
+    driver_opts:
+      com.docker.network.driver.mtu: 1450
+    ...
+</code></pre></div></p>
+<p><strong>4.2.</strong> Users without an IPv6 enabled network on their host system:</p>
+<p><strong>Enable IPv6. Finally.</strong></p>
+<p>If you do not have an IPv6 enabled network on your host and you don't care for a better internet (thehe), it is recommended to <a href="../../post_installation/firststeps-disable_ipv6/">disable IPv6</a> for the mailcow network to prevent unforeseen issues.</p>
+<p><strong>5.</strong> Pull the images and run the compose file. The parameter <code>-d</code> will start mailcow: dockerized detached:
+<div class="highlight"><pre><span></span><code>docker-compose pull
+docker-compose up -d
+</code></pre></div></p>
+<p>Done!</p>
+<p>You can now access <strong>https://${MAILCOW_HOSTNAME}</strong> with the default credentials <code>admin</code> + password <code>moohoo</code>.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>If you are not using mailcow behind a reverse proxy, you should <a href="../../manual-guides/u_e-80_to_443/">redirect all HTTP requests to HTTPS</a>.</p>
+</div>
+<p>The database will be initialized right after a connection to MySQL can be established.</p>
+<p>Your data will persist in multiple Docker volumes, that are not deleted when you recreate or delete containers. Run <code>docker volume ls</code> to see a list of all volumes. You can safely run <code>docker-compose down</code> without removing persistent data.</p>

+  <h1>Migration</h1>
+
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>This guide assumes you intend to migrate an existing mailcow server (source) over to a brand new, empty server (target). It takes no care about preserving any existing data on your target server and will erase anything within <code>/var/lib/docker/volumes</code> and thus any Docker volumes you may have already set up.</p>
+</div>
+<div class="admonition tip">
+<p class="admonition-title">Tip</p>
+<p>Alternatively, you can use the <code>./helper-scripts/backup_and_restore.sh</code> script to create a full backup on the source machine, then install mailcow on the target machine as usual, copy over your <code>mailcow.conf</code> and use the same script to restore your backup to the target machine.</p>
+</div>
+<p><strong>1.</strong> 
+Install <a href="https://docs.docker.com/engine/installation/linux/">Docker</a> and <a href="https://docs.docker.com/compose/install/">Docker Compose</a> on your new server.</p>
+<p>Quick installation for most operation systems:</p>
+<ul>
+<li>
+<p>Docker
+<div class="highlight"><pre><span></span><code>curl -sSL https://get.docker.com/ | CHANNEL=stable sh
+# After the installation process is finished, you may need to enable the service and make sure it is started (e.g. CentOS 7)
+systemctl enable docker.service
+</code></pre></div></p>
+</li>
+<li>
+<p>docker-compose
+<div class="highlight"><pre><span></span><code>curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) &gt; /usr/local/bin/docker-compose
+chmod +x /usr/local/bin/docker-compose
+</code></pre></div></p>
+</li>
+</ul>
+<p>Please use the latest Docker engine available and do not use the engine that ships with your distros repository.</p>
+<p><strong>2.</strong> Stop Docker and assure Docker has stopped:
+<div class="highlight"><pre><span></span><code>systemctl stop docker.service
+systemctl status docker.service
+</code></pre></div></p>
+<p><strong>3.</strong> Run the following commands on the source machine (take care of adding the trailing slashes in the first path parameter as shown below!) - <strong>WARNING: This command will erase anything that may already exist under <code>/var/lib/docker/volumes</code> on the target machine</strong>:
+<div class="highlight"><pre><span></span><code>rsync -aHhP --numeric-ids --delete /opt/mailcow-dockerized/ root@target-machine.example.com:/opt/mailcow-dockerized
+rsync -aHhP --numeric-ids --delete /var/lib/docker/volumes/ root@target-machine.example.com:/var/lib/docker/volumes
+</code></pre></div></p>
+<p><strong>4.</strong> Shut down mailcow and stop Docker on the source machine.
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+docker-compose down
+systemctl stop docker.service
+</code></pre></div></p>
+<p><strong>5.</strong> Repeat step 3 with the same commands. This will be much quicker than the first time.</p>
+<p><strong>6.</strong> Switch over to the target machine and start Docker.
+<div class="highlight"><pre><span></span><code>systemctl start docker.service
+</code></pre></div></p>
+<p><strong>7.</strong> Now pull the mailcow Docker images on the target machine.
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+docker-compose pull
+</code></pre></div></p>
+<p><strong>8.</strong> Start the whole mailcow stack and everything should be done!
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div></p>
+<p><strong>9.</strong> Finally, change your DNS settings to point to the target server.</p>

+<p>An update script in your mailcow-dockerized directory will take care of updates.</p>
+<p>But use it with caution! If you think you made a lot of changes to the mailcow code, you should use the manual update guide below.</p>
+<p>Run the update script:
+<div class="highlight"><pre><span></span><code>./update.sh
+</code></pre></div></p>
+<p>If it needs to, it will ask you how you wish to proceed.
+Merge errors will be reported.
+Some minor conflicts will be auto-corrected (in favour for the mailcow: dockerized repository code).</p>
+<h3 id="options">Options<a class="headerlink" href="#options" title="Permanent link">&para;</a></h3>
+<div class="highlight"><pre><span></span><code># Options can be combined
+
+# - Check for updates and show changes
+./update.sh --check
+
+# Do not try to update docker-compose, **make sure to use the latest docker-compose available**
+./update.sh --no-update-compose
+
+# - Do not start mailcow after applying an update
+./update.sh --skip-start
+
+# - Force update (unattended, but unsupported, use at own risk)
+./update.sh --force
+
+# - Run garbage collector to cleanup old image tags and exit
+./update.sh --gc
+
+# - Update with merge strategy option &quot;ours&quot; instead of &quot;theirs&quot;
+#   This will **solve conflicts** when merging in favor for your local changes and should be avoided. Local changes will always be kept, unless we changed file XY, too.
+./update.sh --ours
+
+# - Don&#39;t update, but prefetch images and exit
+./update.sh --prefetch

+<p>See <code>git log --pretty=oneline | grep -i "before update"</code>, you will have an output similar to this:</p>

+</code></pre></div>
+<p>Run <code>git diff 22cd00b5e28893ef9ddef3c2b5436453cc5223ab</code> to see what changed.</p>
+<h3 id="can-i-roll-back">Can I roll back?<a class="headerlink" href="#can-i-roll-back" title="Permanent link">&para;</a></h3>
+<p>Yes.</p>
+<p>See the topic above, instead of a diff, you run checkout:</p>
+<div class="highlight"><pre><span></span><code>docker-compose down
+# Replace commit ID 22cd00b5e28893ef9ddef3c2b5436453cc5223ab by your ID
+git checkout 22cd00b5e28893ef9ddef3c2b5436453cc5223ab
+docker-compose pull
+docker-compose up -d
+</code></pre></div>
+<h3 id="hooks">Hooks<a class="headerlink" href="#hooks" title="Permanent link">&para;</a></h3>
+<p>You can hook into the update mechanism by adding scripts called <code>pre_commit_hook.sh</code> and <code>post_commit_hook.sh</code> to your mailcows root directory. See <a href="../../manual-guides/u_e-update-hooks/">this</a> for more details.</p>

+  <h1>Vacation replies for catchall addresses</h1>
+
+<p>The Dovecot parameter <code>sieve_vacation_dont_check_recipient</code> - which was by default set to <code>yes</code> in mailcow configurations pre 21st July 2021 - allows for vacation replies even when a mail is sent to non-existent mailboxes like a catch-all addresses.</p>
+<p>We decided to switch this parameter back to <code>no</code> and allow a user to specify which recipient address triggers a vacation reply. The triggering recipients can also be configured in SOGos autoresponder feature.</p>

+  <h1>Expunge a Users mails</h1>
+
+<p>If you want to delete old mails out of the <code>.Junk</code> or <code>.Trash</code> folders or maybe delete all read mails that are older than a certain amount of time you may use dovecot's tool doveadm <a href="https://wiki.dovecot.org/Tools/Doveadm/Expunge">man doveadm-expunge</a>.</p>
+<h2 id="the-manual-way">The manual way<a class="headerlink" href="#the-manual-way" title="Permanent link">&para;</a></h2>
+<p>That said, let's dive in:</p>
+<p>Delete a user's mails inside the junk folder that <strong>are read</strong> and <strong>older</strong> than 4 hours</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm expunge -u &#39;mailbox@example.com&#39; mailbox &#39;Junk&#39; SEEN not SINCE 4h
+</code></pre></div>
+<p>Delete <strong>all</strong> user's mails in the junk folder that are <strong>older</strong> than 7 days</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 7d
+</code></pre></div>
+<p>Delete <strong>all</strong> mails (of all users) in <strong>all</strong> folders that are <strong>older</strong> than 52 weeks (internal date of the mail, not the date it was saved on the system =&gt; <code>before</code> instead of <code>savedbefore</code>). Useful for deleting very old mails on all users and folders (thus especially useful for GDPR-compliance).</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm expunge -A mailbox % before 52w
+</code></pre></div>
+<p>Delete mails inside a custom folder <strong>inside</strong> a user's inbox that are <strong>not</strong> flagged and <strong>older</strong> than 2 weeks</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm expunge -u &#39;mailbox@example.com&#39; mailbox &#39;INBOX/custom-folder&#39; not FLAGGED not SINCE 2w

+<h3 id="via-the-host-system-cron">via the host system cron<a class="headerlink" href="#via-the-host-system-cron" title="Permanent link">&para;</a></h3>
+<p>If you want to automate such a task you can create a cron job on your host that calls a script like the one below:</p>
+<div class="highlight"><pre><span></span><code>#!/bin/bash
+# Path to mailcow-dockerized, e.g. /opt/mailcow-dockerized
+cd /path/to/your/mailcow-dockerized
+
+/usr/local/bin/docker-compose exec -T dovecot-mailcow doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 2w
+/usr/local/bin/docker-compose exec -T dovecot-mailcow doveadm expunge -A mailbox &#39;Junk&#39; SEEN not SINCE 12h
+[...]
+</code></pre></div>
+<p>To create a cron job you may execute <code>crontab -e</code> and insert something like the following to execute a script:</p>
+<div class="highlight"><pre><span></span><code># Execute everyday at 04:00 A.M.
+0 4 * * * /path/to/your/expunge_mailboxes.sh
+</code></pre></div>
+<h3 id="via-docker-job-scheduler">via Docker job scheduler<a class="headerlink" href="#via-docker-job-scheduler" title="Permanent link">&para;</a></h3>
+<p>To archive this with a docker job scheduler use this docker-compose.override.yml with your mailcow: </p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+
+services:
+
+  ofelia:
+    image: mcuadros/ofelia:latest
+    restart: always
+    command: daemon --docker
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock:ro   
+    network_mode: none
+
+  dovecot-mailcow:
+    labels:
+      - &quot;ofelia.enabled=true&quot;
+      - &quot;ofelia.job-exec.dovecot-expunge-trash.schedule=0 4 * * *&quot;
+      - &quot;ofelia.job-exec.dovecot-expunge-trash.command=doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 2w&quot;
+      - &quot;ofelia.job-exec.dovecot-expunge-trash.tty=false&quot;
+</code></pre></div>
+<p>The job controller just need access to the docker control socket to be able to emulate the behavior of "exec". Then we add a few label to our dovecot-container to activate the job scheduler and tell him in a cron compatible scheduling format when to run. If you struggle with that schedule string you can use <a href="https://crontab.guru/">crontab guru</a>. 
+This docker-compose.override.yml deletes all mails older then 2 weeks from the "Junk" folder every day at 4 am. To see if things ran proper, you can not only see in your mailbox but also check Ofelia's docker log if it looks something like this:</p>
+<div class="highlight"><pre><span></span><code>common.go:124 ▶ NOTICE [Job &quot;dovecot-expunge-trash&quot; (8759567efa66)] Started - doveadm expunge -A mailbox &#39;Junk&#39; savedbefore 2w,

+
+<h2 id="fts-solr">FTS Solr<a class="headerlink" href="#fts-solr" title="Permanent link">&para;</a></h2>
+<p>Solr is used for setups with memory &gt;= 3.5 GiB to provide full-text search in Dovecot.</p>
+<p>Please be aware that applications like Solr <em>may</em> need maintenance from time to time.</p>
+<p>Besides that, Solr will eat a lot of RAM, depending on the usage of your server. Please avoid it on machines with less than 3 GB RAM.</p>
+<p>The default heap size (1024 M) is defined in mailcow.conf.</p>
+<p>Since we run in Docker and create our containers with the "restart: always" flag, a oom situation will at least only trigger a restart of the container.</p>
+<h3 id="fts-related-dovecot-commands">FTS related Dovecot commands<a class="headerlink" href="#fts-related-dovecot-commands" title="Permanent link">&para;</a></h3>
+<div class="highlight"><pre><span></span><code># single user
+docker-compose exec dovecot-mailcow doveadm fts rescan -u user@domain
+# all users
+docker-compose exec dovecot-mailcow doveadm fts rescan -A
+</code></pre></div>
+<p>Dovecot Wiki: "Scan what mails exist in the full text search index and compare those to what actually exist in mailboxes. This removes mails from the index that have already been expunged and makes sure that the next doveadm index will index all the missing mails (if any)."</p>
+<p>This does <strong>not</strong> re-index a mailbox. It basically repairs a given index.</p>
+<p>If you want to re-index data immediately, you can run the followig command, where '*' can also be a mailbox mask like 'Sent'. You do not need to run these commands, but it will speed things up a bit:</p>
+<div class="highlight"><pre><span></span><code># single user
+docker-compose exec dovecot-mailcow doveadm index -u user@domain &#39;*&#39;
+# all users, but obviously slower and more dangerous
+docker-compose exec dovecot-mailcow doveadm index -A &#39;*&#39;
+</code></pre></div>
+<p>This <strong>will</strong> take some time depending on your machine and Solr can run oom, monitor it!</p>
+<p>Because re-indexing is very sensible, we did not include it to mailcow UI. You will need to take care of any errors while re-indexing a mailbox.</p>
+<h3 id="delete-mailbox-data">Delete mailbox data<a class="headerlink" href="#delete-mailbox-data" title="Permanent link">&para;</a></h3>
+<p>mailcow will purge index data of a user when deleting a mailbox.</p>

+<h2 id="fts-xapian-release-2022">FTS Xapian (Release 2022)<a class="headerlink" href="#fts-xapian-release-2022" title="Permanent link">&para;</a></h2>
+<p>The Solr replacement Xapian is currently in the development/testing phase.</p>
+<p>Xapian is much more efficient than Solr because it is not based on Java.</p>
+<p>Xapian is also not as vulnerable to security vulnerabilities (which often occur in Java applications).</p>
+<p>The most serious difference between the two FTS is that Xapian (unlike Solr) no longer needs an extra container but from then on runs directly in Dovecot (as a plugin).</p>
+<p>If you want to know more about the Xapian plugin look <a href="https://github.com/grosjo/fts-xapian">here</a>.</p>
+<p><strong>All settings of the mailcow.conf which concern Solr are converted to Xapian</strong>.</p>

+<p>Per default, Dovecot sends a "I'm still here" notification to every client that has an open connection with Dovecot to get mails as quickly as possible without manually polling it (IMAP PUSH). This notification is controlled by the setting <a href="https://wiki.dovecot.org/Timeouts"><code>imap_idle_notify_interval</code></a>, which defaults to 2 minutes. </p>
+<p>A short interval results in the client getting a lot of messages for this connection, which is bad for mobile devices, because every time the device receives this message, the mailing app has to wake up. This can result in unnecessary battery drain.</p>

+<h3 id="change-configuration">Change configuration<a class="headerlink" href="#change-configuration" title="Permanent link">&para;</a></h3>
+<p>Create a new file <code>data/conf/dovecot/extra.conf</code> (or edit it if it already exists).
+Insert the setting followed by the new value. For example, to set the interval to 5 minutes you could type:</p>
+<div class="highlight"><pre><span></span><code>imap_idle_notify_interval = 5 mins
+</code></pre></div>
+<p>29 minutes is the maximum value allowed by the <a href="https://tools.ietf.org/html/rfc2177">corresponding RFC</a>.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>This isn't a default setting in mailcow because we don't know how this setting changes the behavior of other clients. Be careful if you change this and monitor different behavior.</p>
+</div>
+<h3 id="reload-dovecot">Reload Dovecot<a class="headerlink" href="#reload-dovecot" title="Permanent link">&para;</a></h3>

+</code></pre></div></p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>You can check the value of this setting with 
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow dovecot -a | grep &quot;imap_idle_notify_interval&quot;
+</code></pre></div>
+If you didn't change it, it should be at 2m. If you did change it, you should see your new value.</p>

+  <h1>More Examples with DOVEADM</h1>
+
+<p>Here is just an unsorted list of useful <code>doveadm</code> commands that could be useful.</p>
+<h2 id="doveadm-quota">doveadm quota<a class="headerlink" href="#doveadm-quota" title="Permanent link">&para;</a></h2>
+<p>The <code>quota get</code> and <code>quota recalc</code><sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup> commands are used to display or recalculate the current user's quota usage. The reported values are in <em>kilobytes</em>.</p>
+<p>To list the current quota status for a user / mailbox, do:</p>
+<div class="highlight"><pre><span></span><code>doveadm quota get -u &#39;mailbox@example.org&#39;
+</code></pre></div>
+<p>To list the quota storage value for <strong>all</strong> users, do:</p>
+<div class="highlight"><pre><span></span><code>doveadm quota get -A |grep &quot;STORAGE&quot;
+</code></pre></div>
+<p>Recalculate a single user's quota usage:</p>
+<div class="highlight"><pre><span></span><code>doveadm quota recalc -u &#39;mailbox@example.org&#39;
+</code></pre></div>
+<h2 id="doveadm-search">doveadm search<a class="headerlink" href="#doveadm-search" title="Permanent link">&para;</a></h2>
+<p>The <code>doveadm search</code><sup id="fnref:2"><a class="footnote-ref" href="#fn:2">2</a></sup> command is used to find messages matching your query. It can return the username, mailbox-GUID / -UID and message-GUIDs / -UIDs.</p>
+<p>To view the number of messages, by user, in their <strong>.Trash</strong> folder:</p>
+<div class="highlight"><pre><span></span><code>doveadm search -A mailbox &#39;Trash&#39; | awk &#39;{print $1}&#39; | sort | uniq -c
+</code></pre></div>
+<p>Show all messages in a user's <strong>inbox</strong> older then 90 days:</p>
+<div class="highlight"><pre><span></span><code>doveadm search -u &#39;mailbox@example.org&#39; mailbox &#39;INBOX&#39; savedbefore 90d
+</code></pre></div>
+<p>Show <strong>all messages</strong> in <strong>any folder</strong> that are <strong>older</strong> then 30 days for <code>mailbox@example.org</code>:</p>
+<div class="highlight"><pre><span></span><code>doveadm search -u &#39;mailbox@example.org&#39; mailbox &quot;*&quot; savedbefore 30d

+  <h1>Public folders</h1>
+
+<p>Create a new public namespace "Public" and a mailbox "Develcow" inside that namespace:</p>
+<p>Edit or create <code>data/conf/dovecot/extra.conf</code>, add:</p>
+<div class="highlight"><pre><span></span><code>namespace {
+  type = public
+  separator = /
+  prefix = Public/
+  location = maildir:/var/vmail/public:INDEXPVT=~/public
+  subscriptions = yes
+  mailbox &quot;Develcow&quot; {
+    auto = subscribe
+  }
+}
+</code></pre></div>
+<p><code>:INDEXPVT=~/public</code> can be omitted if per-user seen flags are not wanted.</p>
+<p>The new mailbox in the public namespace will be auto-subscribed by users.</p>
+<p>To allow all authenticated users access full to that new mailbox (not the whole namespace), run:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow doveadm acl set -A &quot;Public/Develcow&quot; &quot;authenticated&quot; lookup read write write-seen write-deleted insert post delete expunge create
+</code></pre></div>
+<p>Adjust the command to your needs if you like to assign more granular rights per user (use <code>-u user@domain</code> instead of <code>-A</code> for example).</p>
+<h2 id="allow-authenticated-users-access-to-the-whole-public-namespace">Allow authenticated users access to the whole public namespace<a class="headerlink" href="#allow-authenticated-users-access-to-the-whole-public-namespace" title="Permanent link">&para;</a></h2>
+<p>To allow all authenticated users access full access to the whole public namespace and its subfolders, create a new <code>dovecot-acl</code> file in the namespace root directory:</p>
+<p>Open/edit/create <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/public/dovecot-acl</code> (adjust the path accordingly) to create the global ACL file with the following content:</p>
+<div class="highlight"><pre><span></span><code>authenticated kxeilprwts
+</code></pre></div>
+<p><code>kxeilprwts</code> equals to <code>lookup read write write-seen write-deleted insert post delete expunge create</code>.</p>
+<p>You can use <code>doveadm acl set -u user@domain "Public/Develcow" user=user@domain lookup read</code> to limit access for a single user. You may also turn it around to limit access for all users to "lr" and grant only some users full access.</p>
+<p>See <a href="https://doc.dovecot.org/settings/plugin/acl/">Dovecot ACL</a> for further information about ACL.</p>

+  <h1>Static master user</h1>
+
+<p>Random master usernames and passwords are automatically created on every restart of dovecot-mailcow.</p>
+<p><strong>That's recommended and should not be changed.</strong></p>
+<p>If you need the user to be static anyway, please specify two variables in <code>mailcow.conf</code>.</p>
+<p><strong>Both</strong> parameters must not be empty!</p>
+<div class="highlight"><pre><span></span><code>DOVECOT_MASTER_USER=mymasteruser
+DOVECOT_MASTER_PASS=mysecretpass
+</code></pre></div>
+<p>Run <code>docker-compose up -d</code> to apply your changes.</p>
+<p>The static master username will be expanded to <code>DOVECOT_MASTER_USER@mailcow.local</code>.</p>
+<p>To login as <code>test@example.org</code> this would equal to <code>test@example.org*mymasteruser@mailcow.local</code> with the specified password above.</p>
+<p>A login to SOGo is not possible with this username. A click-to-login function for SOGo is available for admins as described <a href="https://mailcow.github.io/mailcow-dockerized-docs/debug-admin_login_sogo/">here</a>
+No master user is required.</p>

+<p class="admonition-title">Warning</p>
+<p>Newer Docker versions seem to complain about existing volumes. You can fix this temporarily by removing the existing volume and start mailcow with the override file. But it seems to be problematic after a reboot (needs to be confirmed).</p>
+</div>
+<p>An easy, dirty, yet stable workaround is to stop mailcow (<code>docker-compose down</code>), remove <code>/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data</code> and create a new link to your remote filesystem location, for example:</p>
+<div class="highlight"><pre><span></span><code>mv /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data_backup
+ln -s /mnt/volume-xy/vmail_data /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data
+</code></pre></div>
+<p>Start mailcow afterwards.</p>

+<p>If you want to use another folder for the vmail-volume, you can create a <code>docker-compose.override.yml</code> file and add the following content:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+volumes:
+  vmail-vol-1:
+    driver_opts:
+      type: none

+<p>The filename used for a new site is not important, as long as the filename carries a .conf extension.</p>
+<p>It is also possible to extend the configuration of the default file <code>site.conf</code> file:</p>
+<div class="highlight"><pre><span></span><code>nano data/conf/nginx/site.my_content.custom
+</code></pre></div>
+<p>This filename does not need to have a ".conf" extension but follows the pattern <code>site.*.custom</code>, where <code>*</code> is a custom name.</p>
+<p>If PHP is to be included in a custom site, please use the PHP-FPM listener on phpfpm:9002 or create a new listener in <code>data/conf/phpfpm/php-fpm.d/pools.conf</code>.</p>
+<p>Restart Nginx (and PHP-FPM, if a new listener was created):</p>

+  <h1>Create subdomain webmail.example.org</h1>
+
+<p><strong>IMPORTANT</strong>: This guide only applies to non SNI enabled configurations. The certificate path needs to be adjusted if SNI is enabled. Something like <code>ssl_certificate,key /etc/ssl/mail/webmail.example.org/cert.pem,key.pem;</code> will do. <strong>But</strong>: The certificate should be acquired <strong>first</strong> and only after the certificate exists a site config should be created. Nginx will fail to start if it cannot find the certificate and key.</p>
+<p>To create a subdomain <code>webmail.example.org</code> and redirect it to SOGo, you need to create a <strong>new</strong> Nginx site. Take care of "CHANGE_TO_MAILCOW_HOSTNAME"!</p>
+<p><strong>nano data/conf/nginx/webmail.conf</strong></p>
+<div class="highlight"><pre><span></span><code>server {
+  ssl_certificate /etc/ssl/mail/cert.pem;
+  ssl_certificate_key /etc/ssl/mail/key.pem;
+  index index.php index.html;
+  client_max_body_size 0;
+  root /web;
+  include /etc/nginx/conf.d/listen_plain.active;
+  include /etc/nginx/conf.d/listen_ssl.active;
+<span class="hll">  server_name webmail.example.org;

+
+  location / {
+<span class="hll">    return 301 https://CHANGE_TO_MAILCOW_HOSTNAME/SOGo;
+</span>  }
+}
+</code></pre></div>
+<p>Save and restart Nginx: <code>docker-compose restart nginx-mailcow</code>.</p>

+<p>This option is not best-practice and should only be implemented when there is no other option available to achieve whatever you are trying to do.</p>
+<p>Simply create a file <code>data/conf/postfix/check_sasl_access</code> and enter the following content. This user must exist in your installation and needs to authenticate before sending mail.
+<div class="highlight"><pre><span></span><code>user-to-allow-everything@example.com OK
+</code></pre></div></p>
+<p>Open <code>data/conf/postfix/main.cf</code> and find <code>smtpd_sender_restrictions</code>. Prepend <code>check_sasl_access hash:/opt/postfix/conf/check_sasl_access</code> like this:
+<div class="highlight"><pre><span></span><code>smtpd_sender_restrictions = check_sasl_access hash:/opt/postfix/conf/check_sasl_access reject_authenticated_sender_login_mismatch [...]
+</code></pre></div></p>
+<p>Run postmap on check_sasl_access:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec postfix-mailcow postmap /opt/postfix/conf/check_sasl_access

+<p>Restart the Postfix container.</p>

+  <h1>Statistics with pflogsumm</h1>
+
+<p>To use pflogsumm with the default logging driver, we need to query postfix-mailcow via docker logs and pipe the output to pflogsumm:</p>
+<div class="highlight"><pre><span></span><code>docker logs --since 24h $(docker ps -qf name=postfix-mailcow) | pflogsumm
+</code></pre></div>
+<p>The above log output is limited to the past 24 hours.</p>
+<p>It's also possible to create a daily pflogsumm report via cron. Create the file /etc/cron.d/pflogsumm with the following content:</p>
+<div class="highlight"><pre><span></span><code>SHELL=/bin/bash
+59 23 * * * root docker logs --since 24h $(docker ps -qf name=postfix-mailcow) | /usr/sbin/pflogsumm -d today | mail -s &quot;Postfix Report of $(date)&quot; postmaster@example.net
+</code></pre></div>
+<p>Based on the last 24h postfix logs, this example sends every day at 23:59:00 a pflogsumm report to <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#112;&#111;&#115;&#116;&#109;&#97;&#115;&#116;&#101;&#114;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#110;&#101;&#116;">&#112;&#111;&#115;&#116;&#109;&#97;&#115;&#116;&#101;&#114;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#110;&#101;&#116;</a>.</p>

+  <h1>Whitelist IP in Postscreen</h1>
+
+<p>IPs can be removed from Postscreen and therefore <em>also</em> from RBL checks in <code>data/conf/postfix/custom_postscreen_whitelist.cidr</code>.</p>
+<p>Postscreen does multiple checks to identify malicious senders. In most cases you want to whitelist an IP to exclude it from blacklist lookups.</p>
+<p>The format of the file is as follows:</p>
+<p><code>CIDR   ACTION</code></p>
+<p>Where CIDR is a single IP address or IP range in CIDR notation, and action is either "permit" or "reject".</p>
+<p>Example:</p>
+<div class="highlight"><pre><span></span><code># Rules are evaluated in the order as specified.
+# Blacklist 192.168.* except 192.168.0.1.
+192.168.0.1          permit
+192.168.0.0/16       reject
+</code></pre></div>
+<p>The file is reloaded on the fly, postfix restart is not required.</p>

+  <h1>Relayhosts</h1>
+
+<p>As of September 12, 2018 you can setup relayhosts as admin by using the mailcow UI.</p>
+<p>This is useful if you want to relay outgoing emails for a specific domain to a third-party spam filter or a service like Mailgun or Sendgrid. This is also known as a <em>smarthost</em>.</p>
+<h2 id="add-a-new-relayhost">Add a new relayhost<a class="headerlink" href="#add-a-new-relayhost" title="Permanent link">&para;</a></h2>
+<p>Go to the <code>Routing</code> tab of the <code>Configuration and Details</code> section of the admin UI.
+Here you will see a list of relayhosts currently setup.</p>
+<p>Scroll to the <code>Add sender-dependent transport</code> section.</p>
+<p>Under <code>Host</code>, add the host you want to relay to. <br>
+<em>Example: if you want to use Mailgun to send emails instead of your server IP, enter smtp.mailgun.org</em></p>
+<p>If the relay host requires a username and password to authenticate, enter them in the respective fields. <br>
+Keep in mind the credentials will be stored in plain text.</p>
+<h3 id="test-a-relayhost">Test a relayhost<a class="headerlink" href="#test-a-relayhost" title="Permanent link">&para;</a></h3>
+<p>To test that connectivity to the host works, click on <code>Test</code> from the list of relayhosts and enter a <em>From:</em> address. Then, run the test.</p>
+<p>You will then see the results of the SMTP transmission. If all went well, you should see
+<code>SERVER -&gt; CLIENT: 250 2.0.0 Ok: queued as A093B401D4</code> as one of the last lines.</p>
+<p>If not, review the error provided and resolve it.</p>
+<p><strong>Note:</strong> Some hosts, especially those who do not require authentication, will deny connections from servers that have not been added to their system beforehand. Make sure you read the documentation of the relayhost to make sure you've added your domain and/or the server IP to their system.</p>
+<p><strong>Tip:</strong> You can change the default test <em>To:</em> address the test uses from <em>null@mailcow.email</em> to any email address you choose by modifying the <em>$RELAY_TO</em> variable on the <em>vars.inc.php</em> file under <em>/opt/mailcow-dockerized/data/web/inc</em> <br> This way you can check that the relay worked by checking the destination mailbox.</p>
+<h2 id="set-the-relayhost-for-a-domain">Set the relayhost for a domain<a class="headerlink" href="#set-the-relayhost-for-a-domain" title="Permanent link">&para;</a></h2>
+<p>Go to the <code>Domains</code> tab of the <code>Mail setup</code> section of the admin UI.</p>
+<p>Edit the desired domain.</p>
+<p>Select the newly added host on the <code>Sender-dependent transports</code> dropdown and save changes.</p>
+<p>Send an email from a mailbox on that domain and you should see postfix handing the message over to the relayhost in the logs.</p>

+  <h1>Add trusted networks</h1>
+
+<p>By default mailcow considers <strong>all networks as untrusted</strong> excluding its own IPV4_NETWORK and IPV6_NETWORK scopes. Though it is reasonable in most cases, there may be circumstances that you need to loosen this restriction.</p>
+<p>By default mailcow uses <code>mynetworks_style = subnet</code> to determine internal subnets and leaves <code>mynetworks</code> unconfigured.</p>
+<p>If you decide to set <code>mynetworks</code>, Postfix ignores the mynetworks_style setting. This means you <strong>have to</strong> add the IPV4_NETWORK and IPV6_NETWORK scopes as well as loopback subnets manually!</p>

+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Incorrect setup of <code>mynetworks</code> will allow your server to be used as an open relay. If abused, this <strong>will</strong> affect your ability to send emails and can take some time to be resolved.</p>

+<h3 id="ipv4-hostssubnets">IPv4 hosts/subnets<a class="headerlink" href="#ipv4-hostssubnets" title="Permanent link">&para;</a></h3>
+<p>To add the subnet <code>192.168.2.0/24</code> to the trusted networks you may use the following configuration, depending on your IPV4_NETWORK and IPV6_NETWORK scopes:</p>
+<p>Edit <code>data/conf/postfix/extra.cf</code>:</p>
+<div class="highlight"><pre><span></span><code>mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 [fe80::]/10 172.22.1.0/24 [fd4d:6169:6c63:6f77::]/64 192.168.2.0/24

+<p>Adding IPv6 hosts is done the same as IPv4, however the subnet needs to be placed in brackets <code>[]</code> with the netmask appended.</p>
+<p>To add the subnet 2001:db8::/32 to the trusted networks you may use the following configuration, depending on your IPV4_NETWORK and IPV6_NETWORK scopes:</p>
+<p>Edit <code>data/conf/postfix/extra.cf</code>:</p>

+  <h1>Rspamd</h1>
+
+<p>Rspamd is used for AV handling, DKIM signing and SPAM handling. It's a powerful and fast filter system. For a more in-depth documentation on Rspamd please visit its <a href="https://rspamd.com/doc/index.html">own documentation</a>.</p>
+<h2 id="learn-spam-ham">Learn Spam &amp; Ham<a class="headerlink" href="#learn-spam-ham" title="Permanent link">&para;</a></h2>
+<p>Rspamd learns mail as spam or ham when you move a message in or out of the junk folder to any mailbox besides trash.
+This is achieved by using the Sieve plugin "sieve_imapsieve" and parser scripts.</p>
+<p>Rspamd also auto-learns mail when a high or low score is detected (see <a href="https://rspamd.com/doc/configuration/statistic.html#autolearning">https://rspamd.com/doc/configuration/statistic.html#autolearning</a>). We configured the plugin to keep a sane ratio between spam and ham learns.</p>
+<p>The bayes statistics are written to Redis as keys <code>BAYES_HAM</code> and <code>BAYES_SPAM</code>.</p>
+<p>Besides bayes, a local fuzzy storage is used to learn recurring patterns in text or images that indicate ham or spam.</p>
+<p>You can also use Rspamd's web UI to learn ham and / or spam or to adjust certain settings of Rspamd.</p>
+<h3 id="learn-spam-or-ham-from-existing-directory">Learn Spam or Ham from existing directory<a class="headerlink" href="#learn-spam-or-ham-from-existing-directory" title="Permanent link">&para;</a></h3>
+<p>You can use a one-liner to learn mail in plain-text (uncompressed) format:</p>
+<div class="highlight"><pre><span></span><code><span class="c1"># Ham</span>
+<span class="k">for</span> file <span class="k">in</span> /my/folder/cur/*<span class="p">;</span> <span class="k">do</span> docker <span class="nb">exec</span> -i <span class="k">$(</span>docker-compose ps -q rspamd-mailcow<span class="k">)</span> rspamc learn_ham &lt; <span class="nv">$file</span><span class="p">;</span> <span class="k">done</span>
+<span class="c1"># Spam</span>
+<span class="k">for</span> file <span class="k">in</span> /my/folder/.Junk/cur/*<span class="p">;</span> <span class="k">do</span> docker <span class="nb">exec</span> -i <span class="k">$(</span>docker-compose ps -q rspamd-mailcow<span class="k">)</span> rspamc learn_spam &lt; <span class="nv">$file</span><span class="p">;</span> <span class="k">done</span>
+</code></pre></div>
+<p>Consider attaching a local folder as new volume to <code>rspamd-mailcow</code> in <code>docker-compose.yml</code> and learn given files inside the container. This can be used as workaround to parse compressed data with zcat. Example:</p>
+<div class="highlight"><pre><span></span><code><span class="k">for</span> file <span class="k">in</span> /data/old_mail/.Junk/cur/*<span class="p">;</span> <span class="k">do</span> rspamc learn_spam &lt; zcat <span class="nv">$file</span><span class="p">;</span> <span class="k">done</span>
+</code></pre></div>
+<h3 id="reset-learned-data-bayes-neural">Reset learned data (Bayes, Neural)<a class="headerlink" href="#reset-learned-data-bayes-neural" title="Permanent link">&para;</a></h3>
+<p>You need to delete keys in Redis to reset learned data, so create a copy of your Redis database now:</p>
+<p><strong>Backup database</strong></p>
+<div class="highlight"><pre><span></span><code><span class="c1"># It is better to stop Redis before you copy the file.</span>

+<p>Only messages with a higher score will be considered to be greylisted (soft rejected). It is bad practice to disable greylisting.</p>
+<p>You can disable greylisting server-wide by editing:</p>
+<p><code>{mailcow-dir}/data/conf/rspamd/local.d/greylist.conf</code></p>
+<p>Add the line:</p>
+<div class="highlight"><pre><span></span><code><span class="n">enabled</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="nb">false</span><span class="p">;</span><span class="w"></span>

+<h2 id="spam-filter-thresholds-global">Spam filter thresholds (global)<a class="headerlink" href="#spam-filter-thresholds-global" title="Permanent link">&para;</a></h2>
+<p>Each user is able to change <a href="../../mailcow-UI/u_e-mailcow_ui-spamfilter/">their spam rating individually</a>. To define a new <strong>server-wide</strong> limit, edit <code>data/conf/rspamd/local.d/actions.conf</code>:</p>

+</code></pre></div>
+<p>Save the file and restart "rspamd-mailcow": <code>docker-compose restart rspamd-mailcow</code></p>
+<p>Existing settings of users will not be overwritten!</p>
+<p>To reset custom defined thresholds, run:</p>
+<div class="highlight"><pre><span></span><code>source mailcow.conf
+docker-compose exec mysql-mailcow mysql -umailcow -p$DBPASS mailcow -e &quot;delete from filterconf where option = &#39;highspamlevel&#39; or option = &#39;lowspamlevel&#39;;&quot;
+# or:
+# docker-compose exec mysql-mailcow mysql -umailcow -p$DBPASS mailcow -e &quot;delete from filterconf where option = &#39;highspamlevel&#39; or option = &#39;lowspamlevel&#39; and object = &#39;only-this-mailbox@example.org&#39;;&quot;
+</code></pre></div>
+<h2 id="custom-reject-messages">Custom reject messages<a class="headerlink" href="#custom-reject-messages" title="Permanent link">&para;</a></h2>
+<p>The default spam reject message can be changed by adding a new file <code>data/conf/rspamd/override.d/worker-proxy.custom.inc</code> with the following content:</p>
+<div class="highlight"><pre><span></span><code>reject_message = &quot;My custom reject message&quot;;
+</code></pre></div>
+<p>Save the file and restart Rspamd: <code>docker-compose restart rspamd-mailcow</code>.</p>
+<p>While the above works for rejected mails with a high spam score, prefilter reject actions will ignore this setting. For these maps, the multimap module in Rspamd needs to be adjusted:</p>
+<ol>
+<li>
+<p>Find prefilet reject symbol for which you want change message, to do it run: <code>grep -R "SYMBOL_YOU_WANT_TO_ADJUST" /opt/mailcow-dockerized/data/conf/rspamd/</code></p>
+</li>
+<li>
+<p>Add your custom message as new line:</p>
+</li>
+</ol>
+<div class="highlight"><pre><span></span><code>GLOBAL_RCPT_BL {
+  type = &quot;rcpt&quot;;
+  map = &quot;${LOCAL_CONFDIR}/custom/global_rcpt_blacklist.map&quot;;
+  regexp = true;
+  prefilter = true;

+<h2 id="whitelist-specific-clamav-signatures">Whitelist specific ClamAV signatures<a class="headerlink" href="#whitelist-specific-clamav-signatures" title="Permanent link">&para;</a></h2>
+<p>You may find that legitimate (clean) mail is being blocked by ClamAV (Rspamd will flag the mail with <code>VIRUS_FOUND</code>). For instance, interactive PDF form attachments are blocked by default because the embedded Javascript code may be used for nefarious purposes. Confirm by looking at the clamd logs, e.g.:</p>
+<div class="highlight"><pre><span></span><code>docker-compose logs clamd-mailcow <span class="p">|</span> grep <span class="s2">&quot;FOUND&quot;</span>
+</code></pre></div>
+<p>This line confirms that such was identified:</p>
+<div class="highlight"><pre><span></span><code>clamd-mailcow_1      | Sat Sep 28 07:43:24 2019 -&gt; instream(local): PUA.Pdf.Trojan.EmbeddedJavaScript-1(e887d2ac324ce90750768b86b63d0749:363325) FOUND
+</code></pre></div>
+<p>To whitelist this particular signature (and enable sending this type of file attached), add it to the ClamAV signature whitelist file:</p>
+<div class="highlight"><pre><span></span><code><span class="nb">echo</span> <span class="s1">&#39;PUA.Pdf.Trojan.EmbeddedJavaScript-1&#39;</span> &gt;&gt; data/conf/clamav/whitelist.ign2
+</code></pre></div>
+<p>Then restart the clamd-mailcow service container in the mailcow UI or using docker-compose:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart clamd-mailcow
+</code></pre></div>
+<p>Cleanup cached ClamAV results in Redis:</p>
+<div class="highlight"><pre><span></span><code># docker-compose exec redis-mailcow  /bin/sh
+/data # redis-cli KEYS rs_cl* | xargs redis-cli DEL
+/data # exit
+</code></pre></div>
+<h2 id="discard-instead-of-reject">Discard instead of reject<a class="headerlink" href="#discard-instead-of-reject" title="Permanent link">&para;</a></h2>
+<p>If you want to silently drop a message, create or edit the file <code>data/conf/rspamd/override.d/worker-proxy.custom.inc</code> and add the following content:</p>
+<div class="highlight"><pre><span></span><code>discard_on_reject = true;
+</code></pre></div>
+<p>Restart Rspamd:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart rspamd-mailcow
+</code></pre></div>
+<h2 id="wipe-all-ratelimit-keys">Wipe all ratelimit keys<a class="headerlink" href="#wipe-all-ratelimit-keys" title="Permanent link">&para;</a></h2>
+<p>If you don't want to use the UI and instead wipe all keys in the Redis database, you can use redis-cli for that task:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec redis-mailcow sh
+# Unlink (available in Redis &gt;=4.) will delete in the backgronud
+redis-cli --scan --pattern RL* | xargs redis-cli unlink
+</code></pre></div>
+<p>Restart Rspamd:</p>
+<div class="highlight"><pre><span></span><code>docker-compose <span class="nb">exec</span> redis-mailcow sh
+</code></pre></div>
+<h2 id="trigger-a-resend-of-quarantine-notifications">Trigger a resend of quarantine notifications<a class="headerlink" href="#trigger-a-resend-of-quarantine-notifications" title="Permanent link">&para;</a></h2>
+<p>Should be used for debugging only!</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec dovecot-mailcow bash
+mysql -umailcow -p$DBPASS mailcow -e &quot;update quarantine set notified = 0;&quot;
+redis-cli -h redis DEL Q_LAST_NOTIFIED
+quarantine_notify.py
+</code></pre></div>
+<h2 id="increase-history-retention">Increase history retention<a class="headerlink" href="#increase-history-retention" title="Permanent link">&para;</a></h2>
+<p>By default Rspamd keeps 1000 elements in the history.</p>
+<p>The history is stored compressed.</p>
+<p>It is recommended not to use a disproportionate high value here, try something along 5000 or 10000 and see how your server handles it:</p>
+<p>Edit <code>data/conf/rspamd/local.d/history_redis.conf</code>:</p>
+<div class="highlight"><pre><span></span><code>nrows = 1000; # change this value
+</code></pre></div>
+<p>Restart Rspamd afterwards: <code>docker-compose restart rspamd-mailcow</code></p>

+  <h1>Using an external DNS service</h1>
+
+<p>If you want or have to use an external DNS service, you can either set a forwarder in Unbound or copy an override file to define external DNS servers:</p>
+<p>!!! warning
+   Please do not use a public resolver like we did in the example above. Many - if not all - blacklist lookups will fail with public resolvers, because blacklist server has limits on how much requests can be done from one IP and public resolvers usually reach this limits.
+   <strong>Important</strong>: Only DNSSEC validating DNS services will work.</p>
+<h2 id="method-a-unbound">Method A, Unbound<a class="headerlink" href="#method-a-unbound" title="Permanent link">&para;</a></h2>
+<p>Edit <code>data/conf/unbound/unbound.conf</code> and append the following parameters:</p>
+<div class="highlight"><pre><span></span><code>forward-zone:
+  name: &quot;.&quot;
+  forward-addr: 8.8.8.8 # DO NOT USE PUBLIC DNS SERVERS - JUST AN EXAMPLE
+  forward-addr: 8.8.4.4 # DO NOT USE PUBLIC DNS SERVERS - JUST AN EXAMPLE
+</code></pre></div>
+<p>Restart Unbound:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart unbound-mailcow
+</code></pre></div>
+<h2 id="method-b-override-file">Method B, Override file<a class="headerlink" href="#method-b-override-file" title="Permanent link">&para;</a></h2>
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+cp helper-scripts/docker-compose.override.yml.d/EXTERNAL_DNS/docker-compose.override.yml .
+</code></pre></div>
+<p>Edit <code>docker-compose.override.yml</code> and adjust the IP.</p>
+<p>Run <code>docker-compose down ; docker-compose up -d</code>.</p>

+  <h1>Thresholds</h1>
+
+<p>Watchdog uses default values for all thresholds defined in <code>docker-compose.yml</code>.</p>
+<p>The default values will work for most setups.
+Example:
+<div class="highlight"><pre><span></span><code>- NGINX_THRESHOLD=${NGINX_THRESHOLD:-5}
+- UNBOUND_THRESHOLD=${UNBOUND_THRESHOLD:-5}
+- REDIS_THRESHOLD=${REDIS_THRESHOLD:-5}
+- MYSQL_THRESHOLD=${MYSQL_THRESHOLD:-5}
+- MYSQL_REPLICATION_THRESHOLD=${MYSQL_REPLICATION_THRESHOLD:-1}
+- SOGO_THRESHOLD=${SOGO_THRESHOLD:-3}
+- POSTFIX_THRESHOLD=${POSTFIX_THRESHOLD:-8}
+- CLAMD_THRESHOLD=${CLAMD_THRESHOLD:-15}
+- DOVECOT_THRESHOLD=${DOVECOT_THRESHOLD:-12}
+- DOVECOT_REPL_THRESHOLD=${DOVECOT_REPL_THRESHOLD:-20}
+- PHPFPM_THRESHOLD=${PHPFPM_THRESHOLD:-5}
+- RATELIMIT_THRESHOLD=${RATELIMIT_THRESHOLD:-1}
+- FAIL2BAN_THRESHOLD=${FAIL2BAN_THRESHOLD:-1}
+- ACME_THRESHOLD=${ACME_THRESHOLD:-1}
+- RSPAMD_THRESHOLD=${RSPAMD_THRESHOLD:-5}
+- OLEFY_THRESHOLD=${OLEFY_THRESHOLD:-5}
+- MAILQ_THRESHOLD=${MAILQ_THRESHOLD:-20}
+- MAILQ_CRIT=${MAILQ_CRIT:-30}
+</code></pre></div></p>
+<p>To adjust them just add necessary threshold variables (e.g. <code>MAILQ_THRESHOLD=10</code>) to <code>mailcow.conf</code> and run <code>docker-compose up -d</code>.</p>

+  <h1>Configuration</h1>
+
+<p>Several configuration parameters of the mailcow UI can be changed by creating a file <code>data/web/inc/vars.local.inc.php</code> which overrides defaults settings found in <code>data/web/inc/vars.inc.php</code>.</p>
+<p>The local configuration file is persistent over updates of mailcow. Try not to change values inside <code>data/web/inc/vars.inc.php</code>, but use them as template for the local override.</p>
+<p>mailcow UI configuration parameters can be used to...</p>
+<ul>
+<li>...change the default language<sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup></li>
+<li>...change the default bootstrap theme</li>
+<li>...set a password complexity regex</li>
+<li>...enable DKIM private key visibility</li>
+<li>...set a pagination trigger size</li>
+<li>...set default mailbox attributes</li>
+<li>...change session lifetimes</li>
+<li>...create fixed app menus (which cannot be changed in mailcow UI)</li>
+<li>...set a default "To" field for relayhost tests</li>

+<p>The UV flag (as in "user verification") enforces WebAuthn to verify the user before it allows access to the key (think of a PIN). We don't enforce UV to allow logins via iOS and NFC (YubiKey).</p>
+<h2 id="login-and-key-processing">Login and key processing<a class="headerlink" href="#login-and-key-processing" title="Permanent link">&para;</a></h2>
+<p>mailcow uses <strong>client-side key processing</strong>. We ask the authenticator (i.e. YubiKey) to save the registration in its memory.</p>
+<p>A user does not need to enter a username. The available credentials - if any - will be shown to the user when selecting the "key login" via mailcow UI login.</p>
+<p>When calling the login process, the authenticator is not given any credential IDs. This will force it to lookup credentials in its own memory.</p>
+<h2 id="who-can-use-webauthn-to-login-to-mailcow">Who can use WebAuthn to login to mailcow?<a class="headerlink" href="#who-can-use-webauthn-to-login-to-mailcow" title="Permanent link">&para;</a></h2>
+<p>As of today, only administrators and domain administrators are able to setup WebAuthn/FIDO2.</p>

+<p>2. Prepend the tag to the subject: "[facebook] Subject"</p>

+  <h1>Two-Factor Authentication</h1>
+
+<p>So far three methods for <em>Two-Factor Authentication</em> are implemented: WebAuthn (replacing U2F since February 2022), Yubi OTP, and TOTP</p>
+<ul>
+<li>For WebAuthn to work, you need an encrypted connection to the server (HTTPS) as well as a FIDO security key.</li>
+<li>Both WebAuthn and Yubi OTP work well with the fantastic <a href="https://www.yubico.com">Yubikey</a>.</li>
+<li>While Yubi OTP needs an active internet connection and an API ID + key, WebAuthn will work with any Fido Security Key out of the box, but can only be used when mailcow is accessed over HTTPS.</li>
+<li>WebAuthn and Yubi OTP support multiple keys per user.</li>
+<li>As the third TFA method mailcow uses TOTP: time-based one-time passwords. Those passwords can be generated with apps like "Google Authenticator" after initially scanning a QR code or entering the given secret manually.</li>
+</ul>
+<p>As administrator you are able to temporary disable a domain administrators TFA login until they successfully logged in.</p>
+<p>The key used to login will be displayed in green, while other keys remain grey.</p>
+<p>Information on how to remove 2FA can be found <a href="../../../troubleshooting/debug-reset_pw/#remove-two-factor-authentication">here</a>.</p>
+<h2 id="yubi-otp">Yubi OTP<a class="headerlink" href="#yubi-otp" title="Permanent link">&para;</a></h2>
+<p>The Yubi API ID and Key will be checked against the Yubico Cloud API. When setting up TFA you will be asked for your personal API account for this key.
+The API ID, API key and the first 12 characters (your YubiKeys ID in modhex) are stored in the MySQL table as secret.</p>
+<h3 id="example-setup">Example setup<a class="headerlink" href="#example-setup" title="Permanent link">&para;</a></h3>
+<p>First of all, the YubiKey must be configured for use as an OTP Generator. To do this, download the <code>YubiKey Manager</code> from the Yubico website: <a href="https://www.yubico.com/support/download/">here</a></p>
+<p>In the following you configure the YubiKey for OTP.
+Via the menu item <code>Applications</code> -&gt; <code>OTP</code> and a click on the <code>Configure</code> button. In the following menu select <code>Credential Type</code> -&gt; <code>Yubico OTP</code> and click on <code>Next</code>.</p>
+<p>Set a checkmark in the <code>Use serial</code> checkbox, generate a <code>Private ID</code> and a <code>Secret key</code> via the buttons. 
+So that the YubiKey can be validated later, the checkmark in the <code>Upload</code> checkbox must also be set and then click on <code>Finish</code>.</p>
+<p>Now a new browser window will open in which you have to enter an OTP of your YubiKey at the bottom of the form (click on the field and then tap on your YubiKey). Confirm the captcha and upload the information to the Yubico server by clicking 'Upload'. The processing of the data will take a moment.</p>
+<p>After the generation was successful, you will be shown a <code>Client ID</code> and a <code>Secret key</code>, make a note of this information in a safe place.</p>
+<p>Now you can select <code>Yubico OTP authentication</code> from the dropdown menu in the mailcow UI on the start page under <code>Access</code> -&gt; <code>Two-factor authentication</code>. 
+In the dialog that opened now you can enter a name for this YubiKey and insert the <code>Client ID</code> you noted before as well as the <code>Secret key</code> into the fields provided.
+Finally, enter your current account password and, after selecting the <code>Touch Yubikey</code> field, touch your YubiKey button.</p>
+<p>Congratulations! You can now log in to the mailcow UI using your YubiKey!</p>

+<p><strong>Since February 2022 Google Chrome has discarded support for U2F and standardized the use of WebAuthn.<br></strong>
+<em>The WebAuthn (U2F removal) is part of mailcow since 21th January 2022, so if you want to use the Key past February 2022 please consider a update with the <code>update.sh</code></em> </p>

+<p>With this new U2F replacement (WebAuthn) you have to re-register your Fido Security Key, thankfully WebAuthn is backwards compatible and supports the U2F protocol.</p>
+</div>
+<p>Ideally, the next time you log in (with the key), you should get a text box saying that your Fido Security Key has been removed due to the update to WebAuthn and deleted as a 2-factor authenticator.</p>
+<p>But don't worry! You can simply re-register your existing key and use it as usual, you probably won't even notice a difference, except that your browser won't show the U2F deactivation message anymore.</p>
+<h3 id="disable-unofficial-supported-fido-security-keys">Disable unofficial supported Fido Security Keys<a class="headerlink" href="#disable-unofficial-supported-fido-security-keys" title="Permanent link">&para;</a></h3>
+<p>With WebAuthn there is the possibility to use only official Fido Security Keys (from the big brands like: Yubico, Apple, Nitro, Google, Huawei, Microsoft, etc.).</p>
+<p>This is primarily for security purposes, as it allows administrators to ensure that only official hardware can be used in their environment.</p>
+<p>To enable this feature, change the value <code>WEBAUTHN_ONLY_TRUSTED_VENDORS</code> in mailcow.conf from <code>n</code> to <code>y</code> and restart the affected containers with <code>docker-compose up -d</code>.</p>
+<p>The mailcow will now use the Vendor Certificates located in your mailcow directory under <code>data/web/inc/lib/WebAuthn/rootCertificates</code>. </p>
+<h5 id="example">Example:<a class="headerlink" href="#example" title="Permanent link">&para;</a></h5>
+<p>If you want to limit the official Vendor devices to Apple only you only need the Apple Vendor Certificate inside the <code>data/web/inc/lib/WebAuthn/rootCertificates</code>.
+After you deleted all other certs you now only can activate WebAuthn 2FA with Apple devices.</p>
+<p>That´s for every vendor the same, so choose what you like (if you want to).</p>
+<h4 id="use-own-certificates-for-webauthn">Use own certificates for WebAuthn<a class="headerlink" href="#use-own-certificates-for-webauthn" title="Permanent link">&para;</a></h4>
+<p>If you have a valid certificate from the vendor of your key you can also add it to your mailcow!</p>
+<p>Just copy the certificate into the <code>data/web/inc/lib/WebAuthn/rootCertificates</code> folder and restart your mailcow.</p>
+<p>Now you should be able to register this device as well, even though the verification for the vendor certificates is enabled, since you just added the certificate manually. </p>
+<h4 id="is-it-dangerous-to-keep-the-vendor-check-disabled">Is it dangerous to keep the Vendor Check disabled?<a class="headerlink" href="#is-it-dangerous-to-keep-the-vendor-check-disabled" title="Permanent link">&para;</a></h4>
+<p>No, it isn´t!
+These vendor certificates are only used to verify original hardware, not to secure the registration process.</p>
+<p>As you can read in these articles, the deactivation is not software security related:

+<p>In the end, however, it is of course your decision to leave this check disabled or enabled. </p>

+<h2 id="totp">TOTP<a class="headerlink" href="#totp" title="Permanent link">&para;</a></h2>
+<p>The best known TFA method mostly used with a smartphone.</p>
+<p>To setup the TOTP method login to the Admin UI and select <code>Time-based OTP (TOTP)</code> from the list.</p>
+<p>Now a modal will open in which you have to type in a name for your 2FA "device" (example: John Deer´s Smartphone) and the password of the affected Admin account (you are currently logged in with).</p>
+<p>You have two seperate methods to register TOTP to your account:
+1. Scan the QR-Code with your Authenticator App on a Smartphone or Tablet.
+2. Use the TOTP Code (under the QR Code) in your TOTP Program or App (if you can´t scan a QR Code).</p>
+<p>After you have registered the QR or TOTP code in the TOTP app/program of your choice you only need to enter the now generated TOTP token (in the app/program) as confirmation in the mailcow UI to finally activate the TOTP 2FA, otherwise it will not be activated even though the TOTP token is already generated in your app/program.</p>

+  <h1>Redirect HTTP to HTTPS</h1>
+
+<p>Since February the 28th 2017 mailcow does come with port 80 and 443 enabled.</p>
+<p><strong>Do not use the config below for reverse proxy setups</strong>, please see our <a href="../../post_installation/firststeps-rp/">reverse proxy guide</a> for this, which includes a redirect from HTTP to HTTPS.</p>
+<p>Open <code>mailcow.conf</code> and set <code>HTTP_BIND=</code> - if not already set.</p>
+<p>Create a new file <code>data/conf/nginx/redirect.conf</code> and add the following server config to the file:</p>
+<div class="highlight"><pre><span></span><code>server {
+  root /web;
+  listen 80 default_server;
+  listen [::]:80 default_server;
+  include /etc/nginx/conf.d/server_name.active;
+  if ( $request_uri ~* &quot;%0A|%0D&quot; ) { return 403; }
+  location ^~ /.well-known/acme-challenge/ {
+    allow all;
+    default_type &quot;text/plain&quot;;
+  }
+  location / {
+    return 301 https://$host$uri$is_args$args;
+  }
+}
+</code></pre></div>
+<p>In case you changed the HTTP_BIND parameter, recreate the container:</p>
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div>
+<p>Otherwise restart Nginx:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart nginx-mailcow
+</code></pre></div>

+  <h1>Re-enable TLS 1.0 and TLS 1.1</h1>
+
+<p>On February the 12th 2020 we disabled the deprecated protocols TLS 1.0 and 1.1 in Dovecot (POP3, POP3S, IMAP, IMAPS) and Postfix (SMTPS, SUBMISSION).</p>
+<p>Unauthenticated mail via SMTP on port 25/tcp does still accept &gt;= TLS 1.0 . It is better to accept a weak encryption than none at all.</p>
+<p><strong>How to re-enable weak protocols?</strong></p>
+<p>Edit <code>data/conf/postfix/extra.cf</code>:</p>
+<div class="highlight"><pre><span></span><code>submission_smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
+smtps_smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
+</code></pre></div>
+<p>Edit <code>data/conf/dovecot/extra.conf</code>:</p>
+<div class="highlight"><pre><span></span><code>ssl_min_protocol = TLSv1
+</code></pre></div>
+<p>Restart the affected services:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart postfix-mailcow dovecot-mailcow
+</code></pre></div>
+<p>Hint: You can enable TLS 1.2 in Windows 7.</p>

+  <h1>Run scripts before and after updates</h1>
+
+<p>It is possible to add pre- and post-update-hooks to the <code>update.sh</code> script that upgrades your whole mailcow installation.</p>
+<p>To do so, just add the corresponding bash script into your mailcow root directory:  </p>
+<ul>
+<li><code>pre_update_hook.sh</code> for commands that should run before the update</li>
+<li><code>post_update_hook.sh</code> for commands that should run after the update is completed</li>
+</ul>
+<p>Keep in mind that <code>pre_update_hook.sh</code> runs every time you call <code>update.sh</code> and <code>post_update_hook.sh</code> will only run if the update was successful and the script doesn't have to be re-run.</p>
+<p>The scripts will be run by bash, an interpreter (e.g. <code>#!/bin/bash</code>) as well as an execute permission flag ("+x") are not required.</p>

+  <h1>ACL</h1>
+
+<p>Editing a domain administrator or a mailbox user allows to set restrictions to that account.</p>
+<p><strong>Important</strong>: For overlapping modules like sync jobs, which both domain administrators and mailbox users can be granted access to, the domain administrators permissions are inherited, when logging in as mailbox user.</p>
+<p>Some examples:</p>
+<p>1.</p>
+<ul>
+<li>A domain administror has <strong>not</strong> access to sync jobs but can login as mailbox user</li>
+<li>When logging in as mailbox user, he does not gain access to sync jobs, even if the given mailbox user <em>has</em> access when logging in directly</li>
+</ul>
+<p>2.</p>
+<ul>
+<li>A domain administror <strong>has</strong> access to sync jobs and can login as mailbox user</li>
+<li>The mailbox user he tries to login as has <strong>not</strong> access to sync jobs</li>
+<li>The domain administrator, now logged in as mailbox user, inherits its permission to the mailbox user and can access sync jobs</li>
+</ul>
+<p>3.</p>
+<ul>
+<li>A domain administrator logs in as mailbox user</li>
+<li>Every permission, that does <strong>not</strong> exist in a domain administrators ACL, is automatically granted (example: time-limited alias, TLS policy etc.)</li>
+</ul>

+
+<h2 id="fully-supported-hashing-methods">Fully supported hashing methods<a class="headerlink" href="#fully-supported-hashing-methods" title="Permanent link">&para;</a></h2>
+<p>The most current mailcow fully supports the following hashing methods.
+The default hashing method is written in bold:</p>
+<ul>
+<li><strong>BLF-CRYPT</strong></li>
+<li>SSHA</li>
+<li>SSHA256</li>
+<li>SSHA512</li>
+</ul>
+<p>The methods above can be used in <code>mailcow.conf</code> as <code>MAILCOW_PASS_SCHEME</code> value.</p>
+<h2 id="read-only-hashing-methods">Read-only hashing methods<a class="headerlink" href="#read-only-hashing-methods" title="Permanent link">&para;</a></h2>
+<p>The following methods are supported <strong>read only</strong>.
+If you plan to use SOGo (as per default), you need a SOGo compatible hashing method. Please see the note at the bottom of this page how to update the view if necessary.
+With SOGo disabled, all hashing methods below will be able to be read by mailcow and Dovecot.</p>
+<ul>
+<li>ARGON2I (SOGo compatible)</li>
+<li>ARGON2ID (SOGo compatible)</li>
+<li>CLEAR</li>
+<li>CLEARTEXT</li>
+<li>CRYPT (SOGo compatible)</li>
+<li>DES-CRYPT</li>
+<li>LDAP-MD5 (SOGo compatible)</li>
+<li>MD5 (SOGo compatible)</li>
+<li>MD5-CRYPT (SOGo compatible)</li>
+<li>PBKDF2 (SOGo compatible)</li>
+<li>PLAIN (SOGo compatible)</li>
+<li>PLAIN-MD4</li>
+<li>PLAIN-MD5</li>
+<li>PLAIN-TRUNC</li>
+<li>SHA (SOGo compatible)</li>
+<li>SHA1 (SOGo compatible)</li>
+<li>SHA256 (SOGo compatible)</li>
+<li>SHA256-CRYPT (SOGo compatible)</li>
+<li>SHA512 (SOGo compatible)</li>
+<li>SHA512-CRYPT (SOGo compatible)</li>
+<li>SMD5 (SOGo compatible)</li>
+</ul>
+<p>That means mailcow is able to verify users with a hash like <code>{MD5}1a1dc91c907325c69271ddf0c944bc72</code> from the database.</p>
+<p>The value of <code>MAILCOW_PASS_SCHEME</code> will <em>always</em> be used to encrypt new passwords.</p>
+<hr />
+<blockquote>
+<p>I changed the password hashes in the "mailbox" SQL table and cannot login.</p>
+</blockquote>
+<p>A "view" needs to be updated. You can trigger this by restarting sogo-mailcow: <code>docker-compose restart sogo-mailcow</code></p>

+  <h1>Sender and receiver model</h1>
+
+<p>When a mailbox is created, a user is allowed to send mail from and receive mail for his own mailbox address.</p>
+<pre><code>Mailbox me@example.org is created. example.org is a primary domain.
+Note: a mailbox cannot be created in an alias domain.
+
+me@example.org is only known as me@example.org.
+me@example.org is allowed to send as me@example.org.
+</code></pre>
+<p>We can add an alias domain for example.org:</p>
+<pre><code>Alias domain alias.com is added and assigned to primary domain example.org.
+me@example.org is now known as me@example.org and me@alias.com.
+me@example.org is now allowed to send as me@example.org and me@alias.com.
+</code></pre>
+<p>We can add aliases for a mailbox to receive mail for and to send from this new address.</p>
+<p>It is important to know, that you are not able to receive mail for <code>my-alias@my-alias-domain.tld</code>. You would need to create this particular alias.</p>
+<pre><code>me@example.org is assigned the alias alias@example.org
+me@example.org is now known as me@example.org, me@alias.com, alias@example.org
+
+me@example.org is NOT known as alias@alias.com.
+</code></pre>
+<p>Please note that this does not apply to catch-all aliases:</p>
+<pre><code>Alias domain alias.com is added and assigned to primary domain example.org
+me@example.org is assigned the catch-all alias @example.org
+me@example.org is still just known as me@example.org, which is the only available send-as option
+
+Any email send to alias.com will match the catch-all alias for example.org
+</code></pre>
+<p>Administrators and domain administrators can edit mailboxes to allow specific users to send as other mailbox users ("delegate" them).</p>
+<p>You can choose between mailbox users or completely disable the sender check for domains.</p>

+<p>Mailbox users can, obviously, select their own mailbox address, as well as all alias addresses and aliases that exist through alias domains.</p>
+<p>If you want to select another <em>existing</em> mailbox user as your "mail from" address, this user has to delegate you access through SOGo (see SOGo documentation). Moreover a mailcow (domain) administrator
+needs to grant you access as described above.</p>

+  <h1>Disable IPv6</h1>
+
+<p>This is <strong>ONLY</strong> recommended if you do not have an IPv6 enabled network on your host!</p>
+<p>If you really need to, you can disable the usage of IPv6 in the compose file.
+Additionally, you can  also disable the startup of container "ipv6nat-mailcow", as it's not needed if you won't use IPv6.</p>
+<p>Instead of editing docker-compose.yml directly, it is preferable to create an override file for it 
+and implement your changes to the service there. Unfortunately, this right now only seems to work for services, not for network settings.</p>
+<p>To disable IPv6 on the mailcow network, open docker-compose.yml with your favourite text editor and search for the network section (it's near the bottom of the file). </p>
+<p><strong>1.</strong> Modify docker-compose.yml</p>
+<p>Change <code>enable_ipv6: true</code> to <code>enable_ipv6: false</code>:</p>
+<div class="highlight"><pre><span></span><code>networks:
+  mailcow-network:
+    [...]
+    enable_ipv6: true # &lt;&lt;&lt; set to false
+    [...]
+</code></pre></div>
+<p><strong>2.</strong> Disable ipv6nat-mailcow</p>
+<p>To disable the ipv6nat-mailcow container as well, go to your mailcow directory and create a new file called "docker-compose.override.yml": </p>
+<p><strong>NOTE:</strong> If you already have an override file, of course don't recreate it, but merge the lines below into your existing one accordingly!</p>
+<div class="highlight"><pre><span></span><code># cd /opt/mailcow-dockerized
+# touch docker-compose.override.yml
+</code></pre></div>
+<p>Open the file in your favourite text editor and fill in the following:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+    ipv6nat-mailcow:
+      image: bash:latest
+      restart: &quot;no&quot;
+      entrypoint: [&quot;echo&quot;, &quot;ipv6nat disabled in compose.override.yml&quot;]
+</code></pre></div>
+<p>For these changes to be effective, you need to fully stop and then restart the stack, so containers and networks are recreated:</p>
+<div class="highlight"><pre><span></span><code>docker-compose down
+docker-compose up -d
+</code></pre></div>
+<p><strong>3.</strong> Disable IPv6 in unbound-mailcow</p>
+<p>Edit <code>data/conf/unbound/unbound.conf</code> and set <code>do-ip6</code> to "no":</p>
+<div class="highlight"><pre><span></span><code>server:
+  [...]
+  do-ip6: no
+  [...]
+</code></pre></div>
+<p>Restart Unbound:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart unbound-mailcow
+</code></pre></div>
+<p><strong>4.</strong> Disable IPv6 in postfix-mailcow</p>
+<p>Create <code>data/conf/postfix/extra.cf</code> and set <code>smtp_address_preference</code> to <code>ipv4</code>:</p>
+<div class="highlight"><pre><span></span><code>smtp_address_preference = ipv4
+inet_protocols = ipv4
+</code></pre></div>
+<p>Restart Postfix:</p>
+<div class="highlight"><pre><span></span><code>docker-compose restart postfix-mailcow
+</code></pre></div>

+  <h1>DMARC Reporting</h1>
+
+<p>DMARC Reporting done via Rspamd DMARC Module.</p>
+<p>Rspamd documentation can be found here: <a href="https://rspamd.com/doc/modules/dmarc.html">https://rspamd.com/doc/modules/dmarc.html</a></p>
+<p><strong>Important:</strong></p>
+<ol>
+<li>
+<p>Change <code>example.com</code>, <code>mail.example.com</code> and <code>Example</code> to reflect your setup</p>
+</li>
+<li>
+<p>DMARC reporting requires additional attention, especially over the first few days</p>
+</li>
+<li>
+<p>All receiving domains hosted on mailcow send from one reporting domain. It is recommended to use the parent domain of your <code>MAILCOW_HOSTNAME</code>:</p>
+<ul>
+<li>If your <code>MAILCOW_HOSTNAME</code> is <code>mail.example.com</code> change the following config to <code>domain = "example.com";</code></li>
+<li>Set <code>email</code> equally, e.g. <code>email = "noreply-dmarc@example.com";</code></li>
+</ul>
+</li>
+<li>
+<p>It is optional but recommended to create an email user <code>noreply-dmarc</code> in mailcow to handle bounces.</p>
+</li>
+</ol>
+<h2 id="enable-dmarc-reporting">Enable DMARC reporting<a class="headerlink" href="#enable-dmarc-reporting" title="Permanent link">&para;</a></h2>
+<p>Create the file <code>data/conf/rspamd/local.d/dmarc.conf</code> and set the following content:</p>
+<div class="highlight"><pre><span></span><code>reporting {
+    enabled = true;
+    email = &#39;noreply-dmarc@example.com&#39;;
+    domain = &#39;example.com&#39;;

+    smtp_port = 25;
+    from_name = &#39;Example DMARC Report&#39;;
+    msgid_from = &#39;rspamd.mail.example.com&#39;;
+    max_entries = 2k;
+    keys_expire = 2d;
+}
+</code></pre></div>
+<p>Create or modify <code>docker-compose.override.yml</code> in the mailcow-dockerized base directory:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;

+<h2 id="send-a-copy-reports-to-yourself">Send a copy reports to yourself<a class="headerlink" href="#send-a-copy-reports-to-yourself" title="Permanent link">&para;</a></h2>
+<p>To receive a hidden copy of reports generated by Rspamd you can set a <code>bcc_addrs</code> list in the <code>reporting</code> config section of <code>data/conf/rspamd/local.d/dmarc.conf</code>:</p>
+<div class="highlight"><pre><span></span><code>reporting {
+    enabled = true;

+[...]
+</code></pre></div>
+<p>Rspamd will load changes in real time, so you won't need to restart the container at this point.</p>
+<p>This can be useful if you...</p>
+<ul>
+<li>...want to check that your DMARC reports are sent correctly and authenticated.</li>
+<li>...want to analyze your own reports to get statistics, i.e. to use with ParseDMARC or other analytic systems.</li>
+</ul>
+<h2 id="troubleshooting">Troubleshooting<a class="headerlink" href="#troubleshooting" title="Permanent link">&para;</a></h2>
+<p>Check when the report schedule last ran:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow date -r /var/lib/rspamd/dmarc_reports_last_log
+</code></pre></div>
+<p>See the latest report output:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow cat /var/lib/rspamd/dmarc_reports_last_log
+</code></pre></div>
+<p>Manually trigger a DMARC report:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow rspamadm dmarc_report
+</code></pre></div>
+<p>Validate that Rspamd has recorded data in Redis:</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec redis-mailcow redis-cli KEYS &#39;dmarc;*&#39;
+docker-compose exec redis-mailcow redis-cli HGETALL &quot;dmarc;example.com;20211231&quot;
+</code></pre></div>
+<h2 id="change-dmarc-reporting-frequency">Change DMARC reporting frequency<a class="headerlink" href="#change-dmarc-reporting-frequency" title="Permanent link">&para;</a></h2>
+<p>In the example above reports are sent once every 24 hours.</p>
+<p>Olefia schedule has same implementation as <code>cron</code> in Go, supported syntax described at <a href="https://pkg.go.dev/github.com/robfig/cron">cron Documentation</a></p>
+<p>To change schedule:</p>
+<ol>
+<li>
+<p>Edit <code>docker-compose.override.yml</code> and a djust <code>ofelia.job-exec.rspamd_dmarc_reporting.schedule: "@every 24h"</code> to a desired value, for example to <code>"@midnight"</code></p>
+</li>
+<li>
+<p>Run <code>docker-compose up -d</code></p>

+<li>
+<p>Run <code>docker-compose restart ofelia-mailcow</code></p>
+</li>
+</ol>
+<h2 id="disable-dmarc-reporting">Disable DMARC Reporting<a class="headerlink" href="#disable-dmarc-reporting" title="Permanent link">&para;</a></h2>
+<p>To disable reporting:</p>

+<li>
+<p>Set <code>enabled</code> to <code>false</code> in <code>data/conf/rspamd/local.d/dmarc.conf</code></p>
+</li>
+<li>

+<div class="highlight"><pre><span></span><code># For technical reasons, http bindings are a bit different from other service bindings.
+# You will find the following variables, separated by a bind address and its port:
+# Example: HTTP_BIND=1.2.3.4
+
+HTTP_PORT=80
+HTTP_BIND=
+HTTPS_PORT=443
+HTTPS_BIND=
+
+# Other services are bound by using the following format:
+# SMTP_PORT=1.2.3.4:25 will bind SMTP to the IP 1.2.3.4 on port 25
+# Important! Specifying an IPv4 address will skip all IPv6 bindings since Docker 20.x.
+# doveadm, SQL as well as Solr are bound to local ports only, please do not change that, unless you know what you are doing.

+<p>Changing IPv6 bindings is different from IPv4. Again, this has a technical background.</p>
+<p>A <code>docker-compose.override.yml</code> file will be used instead of editing the <code>docker-compose.yml</code> file directly. This is to maintain updatability, as the <code>docker-compose.yml</code> file gets updated regularly and your changes will most likely be overwritten.</p>
+<p>Edit to create a file  <code>docker-compose.override.yml</code> with the following content. Its content will be merged with the productive <code>docker-compose.yml</code> file.</p>
+<p>An imaginary IPv6 <strong>2a00:dead:beef::abc</strong> is given. The first suffix <code>:PORT1</code> defines the external port, while the second suffix <code>:PORT2</code> routes to the corresponding port inside the container and must not be changed.</p>

+  <h1>Local MTA on Docker host</h1>
+
+<p>The easiest option would be to disable the listener on port 25/tcp.</p>
+<p><strong>Postfix</strong> users disable the listener by commenting the following line (starting with <code>smtp</code> or <code>25</code>) in <code>/etc/postfix/master.cf</code>:
+<div class="highlight"><pre><span></span><code>#smtp      inet  n       -       -       -       -       smtpd
+</code></pre></div></p>
+<p>Furthermore, to relay over a dockerized mailcow, you may want to add <code>172.22.1.1</code> as relayhost and remove the Docker interface from "inet_interfaces":</p>
+<div class="highlight"><pre><span></span><code>postconf -e &#39;relayhost = 172.22.1.1&#39;
+postconf -e &quot;mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128&quot;
+postconf -e &quot;inet_interfaces = loopback-only&quot;
+postconf -e &quot;relay_transport = relay&quot;
+postconf -e &quot;default_transport = smtp&quot;
+</code></pre></div>
+<p><strong>Now it is important</strong> to not have the same FQDN in <code>myhostname</code> as you use for your dockerized mailcow. Check your local (non-Docker) Postfix' main.cf for <code>myhostname</code> and set it to something different, for example <code>local.my.fqdn.tld</code>.</p>
+<p>"172.22.1.1" is the mailcow created network gateway in Docker.
+Relaying over this interface is necessary (instead of - for example - relaying directly over ${MAILCOW_HOSTNAME}) to relay over a known internal network.</p>
+<p>Restart Postfix after applying your changes.</p>

+  <h1>Logging</h1>
+
+<p>Logging in mailcow: dockerized consists of multiple stages, but is, after all, much more flexible and easier to integrate into a logging daemon than before.</p>
+<p>In Docker the containerized application (PID 1) writes its output to stdout. For real one-application containers this works just fine.
+Run <code>docker-compose logs --help</code> to learn more. </p>
+<p>Some containers log or stream to multiple destinations.</p>
+<p>No container will keep persistent logs in it. Containers are transient items!</p>
+<p>In the end, every line of logs will reach the Docker daemon - unfiltered.</p>
+<p>The <strong>default logging driver is "json"</strong>.</p>
+<h3 id="filtered-logs">Filtered logs<a class="headerlink" href="#filtered-logs" title="Permanent link">&para;</a></h3>
+<p>Some logs are filtered and written to Redis keys but also streamed to a Redis channel.</p>
+<p>The Redis channel is used to stream logs with failed authentication attempts to be read by netfilter-mailcow.</p>
+<p>The Redis keys are persistent and will keep 10000 lines of logs for the web UI.</p>
+<p>This mechanism makes it possible to use whatever Docker logging driver you want to, without losing 
+the ability to read logs from the UI or ban suspicious clients with netfilter-mailcow.</p>
+<p>Redis keys will only hold logs from applications and filter out system messages (think of cron etc.).</p>
+<h3 id="logging-drivers">Logging drivers<a class="headerlink" href="#logging-drivers" title="Permanent link">&para;</a></h3>
+<h4 id="via-docker-composeoverrideyml">Via docker-compose.override.yml<a class="headerlink" href="#via-docker-composeoverrideyml" title="Permanent link">&para;</a></h4>
+<p>Here is the good news: Since Docker has some great logging drivers, you can integrate mailcow: dockerized into your existing logging environment with ease.</p>
+<p>Create a <code>docker-compose.override.yml</code> and add, for example, this block to use the "gelf" logging plugin for <code>postfix-mailcow</code>:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+  postfix-mailcow: # or any other
+    logging:
+      driver: &quot;gelf&quot;
+      options:
+        gelf-address: &quot;udp://graylog:12201&quot;
+</code></pre></div>
+<p>Another example for <strong>Syslog</strong>:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+  postfix-mailcow: # or any other
+    logging:
+      driver: &quot;syslog&quot;
+      options:
+        syslog-address: &quot;udp://127.0.0.1:514&quot;
+        syslog-facility: &quot;local3&quot;
+
+  dovecot-mailcow: # or any other
+    logging:
+      driver: &quot;syslog&quot;
+      options:
+        syslog-address: &quot;udp://127.0.0.1:514&quot;
+        syslog-facility: &quot;local3&quot;
+
+  rspamd-mailcow: # or any other
+    logging:
+      driver: &quot;syslog&quot;
+      options:
+        syslog-address: &quot;udp://127.0.0.1:514&quot;
+        syslog-facility: &quot;local3&quot;
+
+# For Rsyslog only:
+# To move local3 input to /var/log/mailcow.log and stop processing, create a file &quot;/etc/rsyslog.d/docker.conf&quot;:
+
+local3.*        /var/log/mailcow.logs
+&amp; ~
+
+# Restart rsyslog afterwards.
+</code></pre></div>
+<h4 id="via-daemonjson-globally">via daemon.json (globally)<a class="headerlink" href="#via-daemonjson-globally" title="Permanent link">&para;</a></h4>
+<p>If you want to <strong>change the logging driver globally</strong>, edit Dockers daemon configuration file <code>/etc/docker/daemon.json</code> and restart the Docker service:</p>
+<div class="highlight"><pre><span></span><code>{
+...
+  &quot;log-driver&quot;: &quot;gelf&quot;,
+  &quot;log-opts&quot;: {
+    &quot;gelf-address&quot;: &quot;udp://graylog:12201&quot;
+  }
+...
+}
+</code></pre></div>
+<p>For Syslog:</p>
+<div class="highlight"><pre><span></span><code>{
+...
+  &quot;log-driver&quot;: &quot;syslog&quot;,
+  &quot;log-opts&quot;: {
+    &quot;syslog-address&quot;: &quot;udp://1.2.3.4:514&quot;
+  }
+...
+}
+</code></pre></div>
+<p>Restart the Docker daemon and run <code>docker-compose down &amp;&amp; docker-compose up -d</code> to recreate the containers with the new logging driver.</p>

+  <h1>Reverse Proxy</h1>
+
+<p>You don't need to change the Nginx site that comes with mailcow: dockerized.
+mailcow: dockerized trusts the default gateway IP 172.22.1.1 as proxy.</p>
+<p>1. Make sure you change HTTP_BIND and HTTPS_BIND in <code>mailcow.conf</code> to a local address and set the ports accordingly, for example:
+<div class="highlight"><pre><span></span><code><span class="nv">HTTP_BIND</span><span class="o">=</span><span class="m">127</span>.0.0.1
+<span class="nv">HTTP_PORT</span><span class="o">=</span><span class="m">8080</span>
+<span class="nv">HTTPS_BIND</span><span class="o">=</span><span class="m">127</span>.0.0.1
+<span class="nv">HTTPS_PORT</span><span class="o">=</span><span class="m">8443</span>
+</code></pre></div></p>
+<p>This will also change the bindings inside the Nginx container! This is important, if you decide to use a proxy within Docker.</p>
+<p><strong>IMPORTANT:</strong> Do not use port 8081, 9081 or 65510!</p>
+<p>Recreate affected containers by running <code>docker-compose up -d</code>.</p>
+<p><strong>Important information, please read them carefully!</strong></p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>If you plan to use a reverse proxy and want to use another server name that is <strong>not</strong> MAILCOW_HOSTNAME, you need to read <strong>Adding additional server names for mailcow UI</strong> at the bottom of this page.</p>
+</div>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Make sure you run <code>generate_config.sh</code> before you enable any site configuration examples below.
+The script <code>generate_config.sh</code> copies snake-oil certificates to the correct location, so the services will not fail to start due to missing files.</p>
+</div>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>If you enable TLS SNI (<code>ENABLE_TLS_SNI</code> in mailcow.conf), the certificate paths in your reverse proxy <strong>must</strong> match the correct paths in data/assets/ssl/{hostname}. The certificates will be split into <code>data/assets/ssl/{hostname1,hostname2,etc}</code> and therefore will not work when you copy the examples from below pointing to <code>data/assets/ssl/cert.pem</code> etc.</p>
+</div>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Using the site configs below will <strong>forward ACME requests to mailcow</strong> and let it handle certificates itself.
+The downside of using mailcow as ACME client behind a reverse proxy is, that you will need to reload your webserver after acme-mailcow changed/renewed/created the certificate. You can either reload your webserver daily or write a script to watch the file for changes.
+On many servers logrotate will reload the webserver daily anyway.</p>
+<p>If you want to use a local certbot installation, you will need to change the SSL certificate parameters accordingly.
+<strong>Make sure you run a post-hook script</strong> when you decide to use external ACME clients. You will find an example at the bottom of this page.</p>
+</div>
+<p>2. Configure your local webserver as reverse proxy:</p>
+<h3 id="apache-24">Apache 2.4<a class="headerlink" href="#apache-24" title="Permanent link">&para;</a></h3>
+<p>Required modules:
+<div class="highlight"><pre><span></span><code>a2enmod rewrite proxy proxy_http headers ssl
+</code></pre></div></p>
+<p>Let's Encrypt will follow our rewrite, certificate requests in mailcow will work fine.</p>
+<p><strong>Take care of highlighted lines.</strong></p>

+<p><strong>Important</strong>: This config only covers the "reverseproxing" of the webpannel (nginx-mailcow) using Traefik v2, if you also want to reverseproxy the mail services such as dovecot, postfix... you'll just need to adapt the following config to each container and create an <a href="https://docs.traefik.io/routing/entrypoints/">EntryPoint</a> on your <code>traefik.toml</code> or <code>traefik.yml</code> (depending which config you use) for each port. </p>
+<p>For this section we'll assume you have your Traefik 2 <code>[certificatesresolvers]</code> properly configured on your traefik configuration file, and also using acme, also, the following example uses Lets Encrypt, but feel free to change it to your own cert resolver. You can find a basic Traefik 2 toml config file with all the above implemented which can be used for this example here <a href="https://github.com/Frenzoid/TraefikBasicConfig/blob/master/traefik.toml">traefik.toml</a> if you need one, or a hint on how to adapt your config.</p>
+<p>So, first of all, we are going to disable the acme-mailcow container since we'll use the certs that traefik will provide us.
+For this we'll have to set <code>SKIP_LETS_ENCRYPT=y</code> on our <code>mailcow.conf</code>, and run <code>docker-compose up -d</code> to apply the changes.</p>
+<p>Then we'll create a <code>docker-compose.override.yml</code> file in order to override the main <code>docker-compose.yml</code> found in your mailcow root folder. </p>

+<p>Start the new containers with <code>docker-compose up -d</code>.</p>
+<p>Now, there's only one thing left to do, which is setup the certs so that the mail services can use them as well, since Traefik 2 uses an acme v2 format to save ALL the license from all the domains we have, we'll need to find a way to dump the certs, lucky we have <a href="https://hub.docker.com/r/humenius/traefik-certs-dumper">this tiny container</a> which grabs the <code>acme.json</code> file trough a volume, and a variable <code>DOMAIN=example.org</code>, and with these, the container will output the <code>cert.pem</code> and <code>key.pem</code> files, for this we'll simply run the <code>traefik-certs-dumper</code> container binding the <code>/traefik</code> volume to the folder where our <code>acme.json</code> is saved, bind the <code>/output</code> volume to our mailcow <code>data/assets/ssl/</code> folder, and set up the <code>DOMAIN=example.org</code> variable to the domain we want the certs dumped from. </p>
+<p>This container will watch over the <code>acme.json</code> file for any changes, and regenerate the <code>cert.pem</code> and <code>key.pem</code> files directly into <code>data/assets/ssl/</code> being the path binded to the container's <code>/output</code> path.</p>
+<p>You can use the command line to run it, or use the docker-compose shown <a href="https://hub.docker.com/r/humenius/traefik-certs-dumper">here</a>.</p>
+<p>After we have the certs dumped, we'll have to reload the configs from our postfix and dovecot containers, and check the certs, you can see how <a href="https://mailcow.github.io/mailcow-dockerized-docs/firststeps-ssl/#how-to-use-your-own-certificate">here</a>.</p>
+<p>Aaand that should be it 😊, you can check if the Traefik router works fine trough Traefik's dashboard / traefik logs / accessing the setted domain trough https, or / and check HTTPS, SMTP and IMAP trough the commands shown on the page linked before.</p>

+  <h1>SNAT</h1>
+
+<p>SNAT is used to change the source address of the packets sent by mailcow.
+It can be used to change the outgoing IP address on systems with multiple IP addresses.</p>
+<p>Open <code>mailcow.conf</code>, set either or both of the following parameters:</p>
+<div class="highlight"><pre><span></span><code># Use this IPv4 for outgoing connections (SNAT)
+SNAT_TO_SOURCE=1.2.3.4
+
+# Use this IPv6 for outgoing connections (SNAT)
+SNAT6_TO_SOURCE=dead:beef
+</code></pre></div>
+<p>Run <code>docker-compose up -d</code>.</p>
+<p>The values are read by netfilter-mailcow. netfilter-mailcow will make sure, the post-routing rules are on position 1 in the netfilter table. It does automatically delete and re-create them if they are found on another position than 1.</p>
+<p>Check the output of <code>docker-compose logs --tail=200 netfilter-mailcow</code> to ensure the SNAT settings have been applied.</p>

+<p>mailcow <strong>must</strong> be available on port 80 for the acme-client to work. Our reverse proxy example configurations do cover that. You can also use any external ACME client (certbot for example) to obtain certificates, but you will need to make sure, that they are copied to the correct location and a post-hook reloads affected containers. See more in the Reverse Proxy documentation.</p>
+</div>
+<p>By default, which means <strong>0 domains</strong> are added to mailcow, it will try to obtain a certificate for <code>${MAILCOW_HOSTNAME}</code>.</p>
+<p>For each domain you add, it will try to resolve <code>autodiscover.ADDED_MAIL_DOMAIN</code> and <code>autoconfig.ADDED_MAIL_DOMAIN</code> to its IPv6 address or - if IPv6 is not configured in your domain - IPv4 address. If it succeeds, a name will be added as SAN to the certificate request.</p>
+<p>Only names that can be validated, will be added as SAN.</p>
+<p>For every domain you remove, the certificate will be moved and a new certificate will be requested. It is not possible to keep domains in a certificate, when we are not able validate the challenge for those.</p>
+<p>If you want to re-run the ACME client, use <code>docker-compose restart acme-mailcow</code> and monitor its logs with <code>docker-compose logs --tail=200 -f acme-mailcow</code>.</p>

+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized
+touch data/assets/ssl/force_renew
+docker-compose restart acme-mailcow

+<p>You can skip the <strong>IP verification</strong> by setting <code>SKIP_IP_CHECK=y</code> in mailcow.conf (no quotes). Be warned that a misconfiguration will get you ratelimited by Let's Encrypt! This is primarily useful for multi-IP setups where the IP check would return the incorrect source IP address. Due to using dynamic IPs for acme-mailcow, source NAT is not consistent over restarts.</p>
+<p>If you encounter problems with "HTTP validation", but your IP address confirmation succeeds, you are most likely using firewalld, ufw or any other firewall, that disallows connections from <code>br-mailcow</code> to your external interface. Both firewalld and ufw disallow this by default. It is often not enough to just stop these firewall services. You'd need to stop mailcow (<code>docker-compose down</code>), stop the firewall service, flush the chains and restart Docker.</p>
+<p>You can also skip this validation method by setting <code>SKIP_HTTP_VERIFICATION=y</code> in "mailcow.conf". Be warned that this is discouraged. In most cases, the HTTP verification is skipped to workaround unknown NAT reflection issues, which are not resolved by ignoring this specific network misconfiguration. If you encounter problems generating TLSA records in the DNS overview within mailcow, you are most likely having issues with NAT reflection you should fix.</p>
+<p>If you changed a SKIP_* parameter, run <code>docker-compose up -d</code> to apply your changes.</p>

+<p>Let's Encrypt currently has <a href="https://letsencrypt.org/docs/rate-limits/">a limit of 100 Domain Names per Certificate</a>.</p>
+<p>By default, "acme-mailcow" will create a single SAN certificate for all validated domains
+(see the <a href="#lets-encrypt-out-of-the-box">first section</a> and <a href="#additional-domain-names">Additional domain names</a>).
+This provides best compatibility but means the Let's Encrypt limit exceeds if you add too many domains to a single mailcow installation.</p>
+<p>To solve this, you can configure <code>ENABLE_SSL_SNI</code> to generate:</p>
+<ul>
+<li>A main server certificate with <code>MAILCOW_HOSTNAME</code> and all fully qualified domain names in the <code>ADDITIONAL_SAN</code> config</li>
+<li>One additional certificate for each domain found in the database with autodiscover.<em>, autoconfig.</em> and any other <code>ADDITIONAL_SAN</code> configured in this format (subdomain.*).</li>
+<li>Limitations: A certificate name <code>ADDITIONAL_SAN=test.example.com</code> will be added as SAN to the main certificate. A separate certificate/key pair will <strong>not</strong> be generated for this format.</li>
+</ul>
+<p>Postfix, Dovecot and Nginx will then serve these certificates with SNI.</p>
+<p>Set <code>ENABLE_SSL_SNI=y</code> in "mailcow.conf" and recreate "acme-mailcow" by running <code>docker-compose up -d</code>.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>Not all clients support SNI, <a href="https://wiki.dovecot.org/SSL/SNIClientSupport">see Dovecot documentation</a> or <a href="https://en.wikipedia.org/wiki/Server_Name_Indication#Support">Wikipedia</a>.
+You should make sure these clients use the <code>MAILCOW_HOSTNAME</code> for secure connections if you enable this feature.</p>
+</div>
+<p>Here is an example:</p>
+<ul>
+<li><code>MAILCOW_HOSTNAME=server.email.tld</code></li>
+<li><code>ADDITIONAL_SAN=webmail.email.tld,mail.*</code></li>
+<li>Mailcow email domains: "domain1.tld" and "domain2.tld"</li>
+</ul>
+<p>The following certificates will be generated:</p>
+<ul>
+<li><code>server.email.tld, webmail.email.tld</code> -&gt; this is the default certificate, all clients can connect with these domains</li>
+<li><code>mail.domain1.tld, autoconfig.domain1.tld, autodiscover.domain1.tld</code> -&gt; individual certificate for domain1.tld, cannot be used by clients without SNI support</li>
+<li><code>mail.domain2.tld, autoconfig.domain2.tld, autodiscover.domain2.tld</code> -&gt; individual certificate for domain2.tld, cannot be used by clients without SNI support</li>
+</ul>
+<h3 id="how-to-use-your-own-certificate">How to use your own certificate<a class="headerlink" href="#how-to-use-your-own-certificate" title="Permanent link">&para;</a></h3>
+<p>Make sure you disable mailcows internal LE client (see above).</p>
+<p>To use your own certificates, just save the combined certificate (containing the certificate and intermediate CA/CA if any) to <code>data/assets/ssl/cert.pem</code> and the corresponding key to <code>data/assets/ssl/key.pem</code>.</p>
+<p><strong>IMPORTANT:</strong> Do not use symbolic links! Make sure you copy the certificates and do not link them to <code>data/assets/ssl</code>.</p>
+<p>Restart affected services afterwards:</p>
+<div class="highlight"><pre><span></span><code>docker restart $(docker ps -qaf name=postfix-mailcow)

+<h3 id="check-your-configuration">Check your configuration<a class="headerlink" href="#check-your-configuration" title="Permanent link">&para;</a></h3>
+<p>Run <code>docker-compose logs acme-mailcow</code> to find out why a validation fails.</p>
+<p>To check if nginx serves the correct certificate, simply use a browser of your choice and check the displayed certificate.</p>
+<p>To check the certificate served by Postfix, Dovecot and Nginx we will use <code>openssl</code>:</p>
+<div class="highlight"><pre><span></span><code># Connect via SMTP (587)
+echo &quot;Q&quot; | openssl s_client -starttls smtp -crlf -connect mx.mailcow.email:587
+# Connect via IMAP (143)
+echo &quot;Q&quot; | openssl s_client -starttls imap -showcerts -connect mx.mailcow.email:143
+# Connect via HTTPS (443)
+echo &quot;Q&quot; | openssl s_client -connect mx.mailcow.email:443
+</code></pre></div>
+<p>To validate the expiry dates as returned by openssl against MAILCOW_HOSTNAME, you are able to use our helper script:</p>
+<div class="highlight"><pre><span></span><code>cd /opt/mailcow-dockerized

+
+<p>Sync jobs are used to copy or move existing emails from an external IMAP server or within mailcow's existing mailboxes.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Depending on your mailbox's ACL you may not have the option to add a sync job. Please contact your domain administrator if so.</p>

+<ol>
+<li>
+<p>In the "Configuration &gt; Mail Setup" or "User Settings" interface, create a new sync job.</p>
+</li>
+<li>
+<p>If you are an administrator, select the username of the downstream mailcow mailbox in the "Username" dropdown.</p>
+</li>
+<li>
+<p>Fill in the "Host" and "Port" fields with their respective correct values from the upstream IMAP server.</p>
+</li>
+<li>
+<p>In the "Username" and "Password" fields, supply the correct access credentials from the upstream IMAP server.</p>
+</li>
+<li>
+<p>Select the "Encryption Method". If the upstream IMAP server uses port 143, it is likely that the encryption method is TLS and SSL for port 993. Nevertheless, you can use PLAIN authentication, but it is stongly discouraged.</p>
+</li>
+<li>
+<p>For all ther other fields, you can leave them as is or modify them as desired.</p>
+</li>
+<li>
+<p>Make sure to tick "Active" and click "Add".</p>
+</li>
+</ol>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Once Completed, log into the mailbox and check if all emails are imported correctly. If all goes well, all your mails shall end up in your new mailbox. And don't forget to delete or deactivate the sync job after it is used.</p>

+  <h1>DNS setup</h1>
+
+<p>Below you can find a list of <strong>recommended DNS records</strong>. While some are mandatory for a mail server (A, MX), others are recommended to build a good reputation score (TXT/SPF) or used for auto-configuration of mail clients (SRV).</p>
+<h2 id="references">References<a class="headerlink" href="#references" title="Permanent link">&para;</a></h2>

+<li>A good article covering all relevant topics:

+<h2 id="reverse-dns-of-your-ip-address">Reverse DNS of your IP address<a class="headerlink" href="#reverse-dns-of-your-ip-address" title="Permanent link">&para;</a></h2>
+<p>Make sure that the PTR record of your IP address matches the FQDN of your mailcow host: <code>${MAILCOW_HOSTNAME}</code> <sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup>. This record is usually set at the provider you leased the IP address (server) from.</p>
+<h2 id="the-minimal-dns-configuration">The minimal DNS configuration<a class="headerlink" href="#the-minimal-dns-configuration" title="Permanent link">&para;</a></h2>
+<p>This example shows you a set of records for one domain managed by mailcow. Each domain that is added to mailcow needs at least this set of records to function correctly.</p>
+<div class="highlight"><pre><span></span><code># Name              Type       Value
+mail                IN A       1.2.3.4
+autodiscover        IN CNAME   mail.example.org. (your ${MAILCOW_HOSTNAME})
+autoconfig          IN CNAME   mail.example.org. (your ${MAILCOW_HOSTNAME})
+@                   IN MX 10   mail.example.org. (your ${MAILCOW_HOSTNAME})
+</code></pre></div>
+<h2 id="dkim-spf-and-dmarc">DKIM, SPF and DMARC<a class="headerlink" href="#dkim-spf-and-dmarc" title="Permanent link">&para;</a></h2>
+<p>In the example DNS zone file snippet below, a simple <strong>SPF</strong> TXT record is used to only allow THIS server (the MX) to send mail for your domain. Every other server is disallowed but able to ("<code>~all</code>"). Please refer to <a href="http://www.open-spf.org/">SPF Project</a> for further reading.</p>
+<div class="highlight"><pre><span></span><code># Name              Type       Value
+@                   IN TXT     &quot;v=spf1 mx a -all&quot;
+</code></pre></div>
+<p>It is highly recommended to create a <strong>DKIM</strong> TXT record in your mailcow UI and set the corresponding TXT record in your DNS records. Please refer to <a href="http://www.opendkim.org">OpenDKIM</a> for further reading.</p>
+<div class="highlight"><pre><span></span><code># Name              Type       Value
+dkim._domainkey     IN TXT     &quot;v=DKIM1; k=rsa; t=s; s=email; p=...&quot;
+</code></pre></div>
+<p>The last step in protecting yourself and others is the implementation of a <strong>DMARC</strong> TXT record, for example by using the <a href="http://www.kitterman.com/dmarc/assistant.html">DMARC Assistant</a> (<a href="https://dmarcian.com/dmarc-inspector/google.com">check</a>).</p>
+<div class="highlight"><pre><span></span><code># Name              Type       Value
+_dmarc              IN TXT     &quot;v=DMARC1; p=reject; rua=mailto:mailauth-reports@example.org&quot;
+</code></pre></div>
+<h2 id="the-advanced-dns-configuration">The advanced DNS configuration<a class="headerlink" href="#the-advanced-dns-configuration" title="Permanent link">&para;</a></h2>
+<p><strong>SRV</strong> records specify the server(s) for a specific protocol on your domain. If you want to explicitly announce a service as not provided, give "." as the target address (instead of "mail.example.org.").

+<p>It is worth considering that if you request DMARC statistic reports to your mailcow server and your mailcow server is not configured correctly to receive these reports, you may not get accurate and complete results. Please consider using an alternative email domain for receiving DMARC reports.</p>

+<p>We recommend using any distribution listed as supported by Docker CE (check <a href="https://docs.docker.com/install/">https://docs.docker.com/install/</a>). We test on CentOS 7, Debian 10/11 and Ubuntu 18.04/20.04.</p>
+<p>ClamAV and Solr can be greedy with RAM. You may disable them in <code>mailcow.conf</code> by settings <code>SKIP_CLAMD=y</code> and <code>SKIP_SOLR=y</code>.</p>
+<p><strong>Info</strong>: We are aware that a pure MTA can run on 128 MiB RAM. mailcow is a full-grown and ready-to-use groupware with many extras making life easier. mailcow comes with a webserver, webmailer, ActiveSync (MS), antivirus, antispam, indexing (Solr), document scanner (Oletools), SQL (MariaDB), Cache (Redis), MDA, MTA, various web services etc.</p>
+<p>A single SOGo worker <strong>can</strong> acquire ~350 MiB RAM before it gets purged. The more ActiveSync connections you plan to use, the more RAM you will need. A default configuration spawns 20 workers.</p>
+<h4 id="usage-examples">Usage examples<a class="headerlink" href="#usage-examples" title="Permanent link">&para;</a></h4>
+<p>A company with 15 phones (EAS enabled) and about 50 concurrent IMAP connections should plan 16 GiB RAM.</p>
+<p>6 GiB RAM + 1 GiB swap are fine for most private installations while 8 GiB RAM are recommended for ~5 to 10 users.</p>

+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>There are several problems with running mailcow on a firewalld/ufw enabled system. You should disable it (if possible) and move your ruleset to the DOCKER-USER chain, which is not cleared by a Docker service restart, instead. See <a href="https://blog.donnex.net/docker-and-iptables-filtering/">this (blog.donnex.net)</a> or <a href="https://unrouted.io/2017/08/15/docker-firewall/">this (unrouted.io)</a> guide for information about how to use iptables-persistent with the DOCKER-USER chain.
+As mailcow runs dockerized, INPUT rules have no effect on restricting access to mailcow. Use the FORWARD chain instead.</p>
+</div>
+<p>If this command returns any results please remove or stop the application running on that port. You may also adjust mailcows ports via the <code>mailcow.conf</code> configuration file.</p>

+<p>For all who are struggling with the Hetzner firewall:</p>
+<p>Port 53 unimportant for the firewall configuration in this case. According to the documentation unbound uses the port range 1024-65535 for outgoing requests.
+Since the Hetzner Robot Firewall is a static firewall (each incoming packet is checked isolated) - the following rules must be applied:</p>
+<p><strong>For TCP</strong>
+<div class="highlight"><pre><span></span><code>SRC-IP:       ---
+DST IP:       ---
+SRC Port:    ---
+DST Port:    1024-65535
+Protocol:    tcp
+TCP flags:   ack
+Action:      Accept
+</code></pre></div></p>
+<p><strong>For UDP</strong>
+<div class="highlight"><pre><span></span><code>SRC-IP:       ---
+DST IP:       ---
+SRC Port:    ---
+DST Port:    1024-65535
+Protocol:    udp
+Action:      Accept
+</code></pre></div></p>
+<p>If you want to apply a more restrictive port range you have to change the config of unbound first (after installation):</p>
+<p>{mailcow-dockerized}/data/conf/unbound/unbound.conf:
+<div class="highlight"><pre><span></span><code>outgoing-port-avoid: 0-32767
+</code></pre></div></p>
+<p>Now the firewall rules can be adjusted as follows:</p>
+<div class="highlight"><pre><span></span><code>[...]
+DST Port:  32768-65535
+[...]
+</code></pre></div>
+<h2 id="date-and-time">Date and Time<a class="headerlink" href="#date-and-time" title="Permanent link">&para;</a></h2>
+<p>To ensure that you have the correct date and time setup on your system, please check the output of <code>timedatectl status</code>:</p>

+</code></pre></div>
+<p>The lines <code>NTP enabled: yes</code> and <code>NTP synchronized: yes</code> indicate whether you have NTP enabled and if it's synchronized.</p>
+<p>To enable NTP you need to run the command <code>timedatectl set-ntp true</code>. You also need to edit your <code>/etc/systemd/timesyncd.conf</code>:</p>

+<p>Check <code>/etc/network/interfaces.d/50-cloud-init.cfg</code> and change the IPv6 interface from eth0:0 to eth0:</p>
+<div class="highlight"><pre><span></span><code># Wrong:

+<h2 id="introduction">Introduction<a class="headerlink" href="#introduction" title="Permanent link">&para;</a></h2>
+<p>Borgmatic is a great way to run backups on your Mailcow setup as it securely encrypts your data and is extremely easy to
+set up.</p>
+<p>Due to it's deduplication capabilities you can store a great number of backups without wasting large amounts of disk
+space. This allows you to run backups in very short intervals to ensure minimal data loss when the need arises to
+recover data from a backup.</p>
+<p>This document guides you through the process to enable continuous backups for mailcow with borgmatic. The borgmatic
+functionality is provided by the <a href="https://github.com/b3vis/docker-borgmatic">borgmatic Docker image by b3vis</a>. Check out
+the <code>README</code> in that repository to find out about the other options (such as push notifications) that are available.
+This guide only covers the basics.</p>

+<p>Creating the file in this way ensures the correct MySQL credentials are pulled in from <code>mailcow.conf</code>.</p>
+<p>This file is a minimal example for using borgmatic with an account <code>user</code> on the cloud storage provider <code>rsync.net</code> for
+a repository called <code>mailcow</code> (see <code>repositories</code> setting). It will backup both the maildir and MySQL database, which is
+all you should need to restore your mailcow setup after an incident. The retention settings will keep one archive for
+each hour of the past 24 hours, one per day of the week, one per week of the month and one per month of the past half
+year.</p>
+<p>Check the <a href="https://torsion.org/borgmatic/">borgmatic documentation</a> on how to use other types of repositories or
+configuration options. If you choose to use a local filesystem as a backup destination make sure to mount it into the
+container. The container defines a volume called <code>/mnt/borg-repository</code> for this purpose.</p>
+<div class="admonition note">
+<p class="admonition-title">Note</p>
+<p>If you do not use rsync.net you can most likely drop the <code>remote_path</code> element from your config.</p>

+<p>This file expects crontab syntax. The example shown here will trigger the backup to run every hour at 14 minutes past

+<h3 id="place-ssh-keys-in-folder">Place SSH keys in folder<a class="headerlink" href="#place-ssh-keys-in-folder" title="Permanent link">&para;</a></h3>
+<p>Place the SSH keys you intend to use for remote repository connections in <code>data/conf/borgmatic/ssh</code>. OpenSSH expects the
+usual <code>id_rsa</code>, <code>id_ed25519</code> or similar to be in this directory. Ensure the file is <code>chmod 600</code> and not world readable
+or OpenSSH will refuse to use the SSH key.</p>
+<h3 id="bring-up-the-container">Bring up the container<a class="headerlink" href="#bring-up-the-container" title="Permanent link">&para;</a></h3>
+<p>For the next step we need the container to be up and running in a configured state. To do that run:</p>
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div>
+<h3 id="initialize-the-repository">Initialize the repository<a class="headerlink" href="#initialize-the-repository" title="Permanent link">&para;</a></h3>
+<p>By now your borgmatic container is up and running, but the backups will currently fail due to the repository not being
+initialized.</p>
+<p>To initialize the repository run:</p>
+<div class="highlight"><pre><span></span><code>docker-compose <span class="nb">exec</span> borgmatic-mailcow borgmatic init --encryption repokey-blake2
+</code></pre></div>
+<p>You will be asked you to authenticate the SSH host key of your remote repository server. See if it matches and confirm
+the prompt by entering <code>yes</code>. The repository will be initialized with the passphrase you set in the <code>BORG_PASSPHRASE</code>
+environment variable earlier.</p>
+<p>When using any of the <code>repokey</code> encryption methods the encryption key will be stored in the repository itself and not on
+the client, so there is no further action required in this regard. If you decide to use a <code>keyfile</code> instead of
+a <code>repokey</code> make sure you export the key and back it up separately. Check the <a href="#exporting-keys">Exporting Keys</a> section
+for how to retrieve the key.</p>
+<h3 id="restart-container">Restart container<a class="headerlink" href="#restart-container" title="Permanent link">&para;</a></h3>
+<p>Now that we finished configuring and initializing the repository restart the container to ensure it is in a defined
+state:</p>

+<h2 id="restoring-from-a-backup">Restoring from a backup<a class="headerlink" href="#restoring-from-a-backup" title="Permanent link">&para;</a></h2>

+<div class="admonition warning">

+<div class="admonition note">
+<p class="admonition-title">If you use SELinux in Enforcing mode</p>
+<p>If you are using mailcow on a host with SELinux in Enforcing mode you will have to temporarily disable it during
+extraction of the archive as the mailcow setup labels the vmail volume as private, belonging to the dovecot container
+exclusively. SELinux will (rightfully) prevent any other container, such as the borgmatic container, from writing to
+this volume.</p>
+</div>
+<p>Before running a restore you must make the vmail volume writeable in <code>docker-compose.override.yml</code> by removing
+the <code>ro</code> flag from the volume.
+Then you can use the following command to restore the maildir from a backup:</p>
+<div class="highlight"><pre><span></span><code>docker-compose <span class="nb">exec</span> borgmatic-mailcow borgmatic extract --path mnt/source --archive latest

+<p>To restart mailcow use the follwing command:</p>
+<div class="highlight"><pre><span></span><code>docker-compose down <span class="o">&amp;&amp;</span> docker-compose up -d

+<p>Where <code>user@rsync.net:mailcow</code> is the URI to your repository.</p>

+<h3 id="exporting-keys">Exporting keys<a class="headerlink" href="#exporting-keys" title="Permanent link">&para;</a></h3>
+<p>When using any of the <code>keyfile</code> methods for encryption you <strong>MUST</strong> take care of backing up the key files yourself. The

+repository, so a manual backup isn't as essential.</p>
+<p>Note that in either case you also must have the passphrase to decrypt any archives.</p>
+<p>To fetch the keyfile run:</p>

+  <h1>Exchange Hybrid Setup</h1>
+
+<p>Using Microsoft Exchange in a hybrid setup is possible with mailcow. With this setup you can add mailboxes on your mailcow and still use <a href="https://docs.microsoft.com/microsoft-365/security/office-365-security/exchange-online-protection-overview?view=o365-worldwide">Exchange Online Protection</a>.
+<strong>All mailboxes setup in Exchange will receive their mails as usual</strong>, while with the hybrid approach additional Mailboxes can be setup in mailcow without any further configuration.</p>
+<p>This setup becomes very handy if you have enabled the <a href="https://docs.microsoft.com/azure/active-directory/fundamentals/concept-fundamentals-security-defaults">Office 365 security defaults</a> and third party applications can no longer login into your mailboxes by any of the <a href="https://docs.microsoft.com/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365">supported methods</a>.</p>
+<h2 id="requirements">Requirements<a class="headerlink" href="#requirements" title="Permanent link">&para;</a></h2>
+<ul>
+<li>The mx Record of your domain needs to point at the Exchange mail service. Log into your Admin center and look out for the dns settings of your domain to find your personalized gateway domain. It should look like this <code>contoso-com.mail.protection.outlook.com</code>. Contact your domain registrant to get further information on how to change mx record.</li>
+<li>The domain you want to have additional mailboxes for must be setup as <code>internal relay domain</code> in Exchange.<ol>
+<li>Log in to your <a href="https://admin.exchange.microsoft.com">Exchange Admin Center</a></li>
+<li>Select the <code>mail flow</code> pane and click on <code>accepted domains</code></li>
+<li>Select the domain and switch it from <code>authorative</code> to <code>internal relay</code></li>
+</ol>
+</li>
+</ul>
+<h2 id="set-up-the-mailcow">Set up the mailcow<a class="headerlink" href="#set-up-the-mailcow" title="Permanent link">&para;</a></h2>
+<p>Your mailcow needs to relay all mails to your personalized Exchange Host. It is the same host address we already looked up for the mx Record.</p>
+<ol>
+<li>Add the domain to your mailcow</li>
+<li><a href="../../manual-guides/Postfix/u_e-postfix-relayhost/">Add your personalized Exchange Host address as relayhost</a></li>
+<li>Add your personalized Exchange Host address as forwarding host to unconditionally accepted all relayed mails from Exchange. (Admin &gt; Configuration &amp; Details &gt; Configuration Dropdown &gt; Forwarding Hosts)</li>
+<li>Go to the domain settings and select the newly added host on the <code>Sender-dependent transports</code> dropdown. Enable relaying by ticking the <code>Relay this domain</code>, <code>Relay all recipients</code> and the <code>Relay non-existing mailboxes only.</code> checkboxes</li>
+</ol>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>From now on your mailcow will accept all mails relayed from Exchange. The <strong>inbound filtering and so the neural learning of your cow will no longer work</strong>. Because all mails are routed through Exchange the <a href="https://docs.microsoft.com/exchange/antispam-and-antimalware/antispam-and-antimalware?view=exchserver-2019">filtering process is handled there</a>.</p>
+</div>
+<h2 id="set-up-connectors-in-exchange">Set up Connectors in Exchange<a class="headerlink" href="#set-up-connectors-in-exchange" title="Permanent link">&para;</a></h2>
+<p>All mail traffic now goes through Exchange. At this point the Exchange Online Protection already filters all incoming and outgoing mails. Now we need to set up two connectors to relay incoming mails from our Exchange Service to the mailcow and another one to allow mails relayed from the mailcow to our exchange service. You can follow the <a href="https://docs.microsoft.com/exchange/mail-flow-best-practices/use-connectors-to-configure-mail-flow/set-up-connectors-to-route-mail#2-set-up-a-connector-from-microsoft-365-or-office-365-to-your-email-server">official guide from Microsoft</a>.</p>
+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>For the connector that handles mails from your mailcow to Exchange Microsoft offers two ways of authenticating it. The recommended way is to use a tls certificate configured with a subject name that matches an accepted domain in Exchange. Otherwise you need to choose authentication with the static ip address of your mailcow.</p>
+</div>
+<h2 id="validating">Validating<a class="headerlink" href="#validating" title="Permanent link">&para;</a></h2>
+<p>The easiest way to validate the hybrid setup is by sending a mail from the internet to a mailbox that only exists on the mailcow and vice versa.</p>
+<h3 id="common-issues">Common Issues<a class="headerlink" href="#common-issues" title="Permanent link">&para;</a></h3>
+<ul>
+<li>The connector validation from Exchange to your mailcow failed with <code>550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient test@contoso.com not found by SMTP address lookup</code><br />
+<strong>Possible Solution:</strong> Your domain is not set up as <code>internal relay</code>. Exchange therefore cannot find the recipient</li>
+<li>Mails sent from the mailcow to a mailbox in the internet cannot be sent. Non Delivery Report with error <code>550 5.7.64 TenantAttribution; Relay Access Denied</code><br />
+<strong>Possible Solution:</strong> The authentication method failed. Make sure the certificate subject matches an accepted domain in Exchange. Try authenticating by static ip instead.</li>

+  <h1>Gitea</h1>
+
+<p>With Gitea' ability to authenticate over SMTP it is trivial to integrate it with mailcow. Few changes are needed:</p>
+<p>1. Open <code>docker-compose.override.yml</code> and add gitea:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+        gitea-mailcow:
+            image: gitea/gitea:1
+            volumes:
+                - ./data/gitea:/data
+            networks:
+                mailcow-network:
+                    aliases:
+                        - gitea
+            ports:
+                - &quot;${GITEA_SSH_PORT:-127.0.0.1:4000}:22&quot;
+</code></pre></div>
+<p>2. Create <code>data/conf/nginx/site.gitea.custom</code>, add:
+<div class="highlight"><pre><span></span><code>location /gitea/ {
+        proxy_pass http://gitea:3000/;
+}
+</code></pre></div></p>
+<p>3. Open <code>mailcow.conf</code> and define the binding you want gitea to use for SSH. Example:</p>
+<div class="highlight"><pre><span></span><code>GITEA_SSH_PORT=127.0.0.1:4000
+</code></pre></div>
+<p>5. Run <code>docker-compose up -d</code> to bring up the gitea container and run <code>docker-compose restart nginx-mailcow</code> afterwards.</p>
+<p>6. If you forced mailcow to https, execute step 9 and restart gitea with <code>docker-compose restart gitea-mailcow</code> . Go head with step 7 (Remember to use https instead of http, <code>https://mx.example.org/gitea/</code> </p>
+<p>7. Open <code>http://${MAILCOW_HOSTNAME}/gitea/</code>, for example <code>http://mx.example.org/gitea/</code>. For database details set <code>mysql</code> as database host. Use the value of DBNAME found in mailcow.conf as database name, DBUSER as database user and DBPASS as database password.</p>
+<p>8. Once the installation is complete, login as admin and set "settings" -&gt; "authorization" -&gt; "enable SMTP". SMTP Host should be <code>postfix</code> with port <code>587</code>, set <code>Skip TLS Verify</code> as we are using an unlisted SAN ("postfix" is most likely not part of your certificate).</p>
+<p>9. Create <code>data/gitea/gitea/conf/app.ini</code> and set following values. You can consult <a href="https://docs.gitea.io/en-us/config-cheat-sheet/">gitea cheat sheet</a> for their meaning and other possible values.</p>
+<div class="highlight"><pre><span></span><code>[server]
+SSH_LISTEN_PORT = 22
+# For GITEA_SSH_PORT=127.0.0.1:4000 in mailcow.conf, set:
+SSH_DOMAIN = 127.0.0.1
+SSH_PORT = 4000
+# For MAILCOW_HOSTNAME=mx.example.org in mailcow.conf (and default ports for HTTPS), set:
+ROOT_URL = https://mx.example.org/gitea/
+</code></pre></div>
+<p>10. Restart gitea with <code>docker-compose restart gitea-mailcow</code>. Your users should be able to login with mailcow managed accounts.</p>

+  <h1>Gogs</h1>
+
+<p>With Gogs' ability to authenticate over SMTP it is trivial to integrate it with mailcow. Few changes are needed:</p>
+<p>1. Open <code>docker-compose.override.yml</code> and add Gogs:</p>
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+
+    gogs-mailcow:
+      image: gogs/gogs
+      volumes:
+        - ./data/gogs:/data
+      networks:
+        mailcow-network:
+          aliases:
+            - gogs
+      ports:
+        - &quot;${GOGS_SSH_PORT:-127.0.0.1:4000}:22&quot;
+</code></pre></div>
+<p>2. Create <code>data/conf/nginx/site.gogs.custom</code>, add:
+<div class="highlight"><pre><span></span><code>location /gogs/ {
+    proxy_pass http://gogs:3000/;
+}
+</code></pre></div></p>
+<p>3. Open <code>mailcow.conf</code> and define the binding you want Gogs to use for SSH. Example:</p>
+<div class="highlight"><pre><span></span><code>GOGS_SSH_PORT=127.0.0.1:4000
+</code></pre></div>
+<p>5. Run <code>docker-compose up -d</code> to bring up the Gogs container and run <code>docker-compose restart nginx-mailcow</code> afterwards.</p>
+<p>6. Open <code>http://${MAILCOW_HOSTNAME}/gogs/</code>, for example <code>http://mx.example.org/gogs/</code>. For database details set <code>mysql</code> as database host. Use the value of DBNAME found in mailcow.conf as database name, DBUSER as database user and DBPASS as database password.</p>
+<p>7. Once the installation is complete, login as admin and set "settings" -&gt; "authorization" -&gt; "enable SMTP". SMTP Host should be <code>postfix</code> with port <code>587</code>, set <code>Skip TLS Verify</code> as we are using an unlisted SAN ("postfix" is most likely not part of your certificate).</p>
+<p>8. Create <code>data/gogs/gogs/conf/app.ini</code> and set following values. You can consult <a href="https://gogs.io/docs/advanced/configuration_cheat_sheet">Gogs cheat sheet</a> for their meaning and other possible values.</p>
+<div class="highlight"><pre><span></span><code>[server]
+SSH_LISTEN_PORT = 22
+# For GOGS_SSH_PORT=127.0.0.1:4000 in mailcow.conf, set:
+SSH_DOMAIN = 127.0.0.1
+SSH_PORT = 4000
+# For MAILCOW_HOSTNAME=mx.example.org in mailcow.conf (and default ports for HTTPS), set:
+ROOT_URL = https://mx.example.org/gogs/
+</code></pre></div>
+<p>9. Restart Gogs with <code>docker-compose restart gogs-mailcow</code>. Your users should be able to login with mailcow managed accounts.</p>

+<p>This guide aims to install and configure <a href="https://github.com/mailcow/mailcow-dockerized">mailcow-dockerized</a> with <a href="https://github.com/maxking/docker-mailman">docker-mailman</a> and to provide some useful scripts. An essential condition is, to preserve <em>mailcow</em> and <em>Mailman</em> in their own installations for independent updates.</p>
+<p>There are some guides and projects on the internet, but they are not up to date and/or incomplete in documentation or configuration. This guide is based on the work of:</p>
+<ul>
+<li><a href="https://github.com/Shadowghost/mailcow-mailman3-dockerized">mailcow-mailman3-dockerized</a> by <a href="https://github.com/Shadowghost">Shadowghost</a></li>
+<li><a href="https://gitbucket.pgollor.de/docker/mailman-mailcow-integration">mailman-mailcow-integration</a></li>
+</ul>
+<p>After finishing this guide, <a href="https://github.com/mailcow/mailcow-dockerized">mailcow-dockerized</a> and <a href="https://github.com/maxking/docker-mailman">docker-mailman</a> will run and <em>Apache</em> as a reverse proxy will serve the web frontends.</p>
+<p>The operating system used is an <em>Ubuntu 20.04 LTS</em>.</p>

+  <h1>Mailpiler Integration</h1>
+
+<p>This is a simple integration of mailcow aliases and the mailbox name into mailpiler when using IMAP authentication.</p>
+<p><strong>Disclaimer</strong>: This is not officially maintained nor supported by the mailcow project nor its contributors. No warranty or support is being provided, however you're free to open issues on GitHub for filing a bug or provide further ideas. <a href="https://github.com/patschi/mailpiler-mailcow-integration">GitHub repo can be found here</a>.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Support for domain wildcards were implemented in Piler 1.3.10 which was released on 03.01.2021. Prior versions basically do work, but after logging in you won't see emails sent from or to the domain alias. (e.g. when @example.com is an alias for <a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#97;&#100;&#109;&#105;&#110;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#99;&#111;&#109;">&#97;&#100;&#109;&#105;&#110;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#99;&#111;&#109;</a>)</p>
+</div>
+<h2 id="the-problem-to-solve">The problem to solve<a class="headerlink" href="#the-problem-to-solve" title="Permanent link">&para;</a></h2>
+<p>mailpiler offers the authentication based on IMAP, for example:</p>
+<div class="highlight"><pre><span></span><code><span class="x">$config[&#39;ENABLE_IMAP_AUTH&#39;] = 1;</span>
+<span class="x">$config[&#39;IMAP_HOST&#39;] = &#39;mail.example.com&#39;;</span>
+<span class="x">$config[&#39;IMAP_PORT&#39;] =  993;</span>
+<span class="x">$config[&#39;IMAP_SSL&#39;] = true;</span>
+</code></pre></div>
+<ul>
+<li>So when you log in using <code>patrik@example.com</code>, you will only see delivered emails sent from or to this specific email address.</li>
+<li>When additional aliases are defined in mailcow, like <code>team@example.com</code>, you won't see emails sent to or from this email address even the fact you're a recipient of mails sent to this alias address.</li>
+</ul>
+<p>By hooking into the authentication process of mailpiler, we are able to get required data via the mailcow API during login. This fires API requests to the mailcow API (requiring read-only API access) to read out the aliases your email address participates and also the "Name" of the mailbox specified to display it on the top-right of mailpiler after login.</p>
+<p>Permitted email addresses can be seen in the mailpiler settings top-right after logging in.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>This is only pulled once during the authentication process. The authorized aliases and the realname are valid for the whole duration of the user session as mailpiler sets them in the session data. If user is removed from specific alias, this will only take effect after next login.</p>

+<div class="admonition warning">
+<p class="admonition-title">Warning</p>
+<p>As mailpiler authenticates against mailcow, our IMAP server, failed logins of users or bots might trigger a block for your mailpiler instance. Therefore you might want to consider whitelisting the IP address of the mailpiler instance within mailcow: <code>Configuration &amp; Details - Configuration - Fail2ban parameters - Whitelisted networks/hosts</code>.</p>

+<p>Set the custom query function of mailpiler and append this to <code>/usr/local/etc/piler/config-site.php</code>:</p>
+<div class="highlight"><pre><span></span><code><span class="x">$config[&#39;MAILCOW_API_KEY&#39;] = &#39;YOUR_READONLY_API_KEY&#39;;</span>
+<span class="x">$config[&#39;MAILCOW_SET_REALNAME&#39;] = true; // when not specified, then default is false</span>
+<span class="x">$config[&#39;CUSTOM_EMAIL_QUERY_FUNCTION&#39;] = &#39;query_mailcow_for_email_access&#39;;</span>
+<span class="x">include(&#39;auth-mailcow.php&#39;);</span>
+</code></pre></div>
+<p>You can also change the mailcow hostname, if required:
+<div class="highlight"><pre><span></span><code><span class="x">$config[&#39;MAILCOW_HOST&#39;] = &#39;mail.domain.tld&#39;; // defaults to $config[&#39;IMAP_HOST&#39;]</span>
+</code></pre></div></p>
+</li>
+<li>
+<p>Download the PHP file with the functions from the <a href="https://github.com/patschi/mailpiler-mailcow-integration">GitHub repo</a>:</p>
+<div class="highlight"><pre><span></span><code>curl -o /usr/local/etc/piler/auth-mailcow.php https://raw.githubusercontent.com/patschi/mailpiler-mailcow-integration/master/auth-mailcow.php
+</code></pre></div>
+</li>
+<li>
+<p>Done!</p>
+</li>
+</ol>
+<p>Make sure to re-login with your IMAP credentials for changes to take effect.</p>
+<p>If it doesn't work, most likely something's wrong with the API query itself. Consider debugging by sending manual API requests to the API. (Tip: Open <code>https://mail.domain.tld/api</code> on your instance)</p>

+<p>Nextcloud can be set up (parameter <code>-i</code>) and removed (parameter <code>-p</code>) with the <a href="https://github.com/mailcow/mailcow-dockerized/raw/master/helper-scripts/nextcloud.sh">helper script</a> included with mailcow. In order to install Nextcloud simply navigate to your mailcow-dockerized root folder and run the helper script as follows:</p>
+<p><code>./helper-scripts/nextcloud.sh -i</code></p>
+<p>In case you have forgotten the password (e.g. for admin) and can't request a new one <a href="https://docs.nextcloud.com/server/20/admin_manual/configuration_user/reset_admin_password.html?highlight=reset">via the password reset link on the login screen</a> calling the helper script with <code>-r</code> as parameter allows you to set a new password. Only use this option if your Nextcloud isn't configured to use mailcow for authentication as described in the next section.</p>
+<h2 id="configure-nextcloud-to-use-mailcow-for-authentication">Configure Nextcloud to use mailcow for authentication<a class="headerlink" href="#configure-nextcloud-to-use-mailcow-for-authentication" title="Permanent link">&para;</a></h2>
+<p>The following describes how set up authentication via mailcow using the OAuth2 protocol. We will only assume that you have already set up Nextcloud at <em>cloud.example.com</em> and that your mailcow is running at <em>mail.example.com</em>. It does not matter if your Nextcloud is running on a different server, you can still use mailcow for authentication.</p>
+<p>1. Log into mailcow as administrator.</p>
+<p>2. Scroll down to <em>OAuth2 Apps</em> and click the <em>Add</em> button. Specify the redirect URI as <code>https://cloud.example.com/index.php/apps/sociallogin/custom_oauth2/Mailcow</code> and click <em>Add</em>. Save the client ID and secret for later.</p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>Some installations, including those setup using the helper script of mailcow, need to remove index.php/ from the URL to get a successful redirect: <code>https://cloud.example.com/apps/sociallogin/custom_oauth2/Mailcow</code></p>
+</div>
+<p>3. Log into Nextcloud as administrator.</p>
+<p>4. Click the button in the top right corner and select <em>Apps</em>. Click the search button in the toolbar, search for the <a href="https://apps.nextcloud.com/apps/sociallogin"><em>Social Login</em></a> plugin and click <em>Download and enable</em> next to it.</p>
+<p>5. Click the button in the top right corner and select <em>Settings</em>. Scroll down to the <em>Administration</em> section on the left and click <em>Social login</em>.</p>
+<p>6. Uncheck the following items:</p>
+<ul>
+<li>"Disable auto create new users"</li>
+<li>"Allow users to connect social logins with their accounts"</li>
+<li>"Do not prune not available user groups on login"</li>
+<li>"Automatically create groups if they do not exists"</li>
+<li>"Restrict login for users without mapped groups"</li>
+</ul>
+<p>7. Check the following items:</p>
+<ul>
+<li>"Prevent creating an account if the email address exists in another account"</li>
+<li>"Update user profile every login"</li>
+<li>"Disable notify admins about new users"</li>
+</ul>
+<p>Click the <em>Save</em> button.</p>
+<p>8. Scroll down to <em>Custom OAuth2</em> and click the <em>+</em> button.
+9. Configure the parameters as follows:</p>
+<ul>
+<li>Internal name: <code>Mailcow</code></li>
+<li>Title: <code>Mailcow</code></li>
+<li>API Base URL: <code>https://mail.example.com</code></li>
+<li>Authorize URL: <code>https://mail.example.com/oauth/authorize</code></li>
+<li>Token URL: <code>https://mail.example.com/oauth/token</code></li>
+<li>Profile URL: <code>https://mail.example.com/oauth/profile</code></li>
+<li>Logout URL: (leave blank)</li>
+<li>Client ID: (what you obtained in step 1)</li>
+<li>Client Secret: (what you obtained in step 1)</li>
+<li>Scope: <code>profile</code></li>
+</ul>
+<p>Click the <em>Save</em> button at the very bottom of the page.</p>
+<hr />
+<p>If you have previously used Nextcloud with mailcow authentication via user_external/IMAP, you need to perform some additional steps to link your existing user accounts with OAuth2.</p>
+<p>1. Click the button in the top right corner and select <em>Apps</em>. Scroll down to the <em>External user authentication</em> app and click <em>Remove</em> next to it.
+2. Run the following queries in your Nextcloud database (if you set up Nextcloud using mailcow's script, you can run <code>source mailcow.conf &amp;&amp; docker-compose exec mysql-mailcow mysql -u$DBUSER -p$DBPASS $DBNAME</code>):
+<div class="highlight"><pre><span></span><code>INSERT INTO nc_users (uid, uid_lower) SELECT DISTINCT uid, LOWER(uid) FROM nc_users_external;
+INSERT INTO nc_sociallogin_connect (uid, identifier) SELECT DISTINCT uid, CONCAT(&quot;Mailcow-&quot;, uid) FROM nc_users_external;
+</code></pre></div></p>
+<hr />
+<p>If you have previously used Nextcloud without mailcow authentication, but with the same usernames as mailcow, you can also link your existing user accounts with OAuth2.</p>
+<p>1. Run the following queries in your Nextcloud database (if you set up Nextcloud using mailcow's script, you can run <code>source mailcow.conf &amp;&amp; docker-compose exec mysql-mailcow mysql -u$DBUSER -p$DBPASS $DBNAME</code>):
+<div class="highlight"><pre><span></span><code>INSERT INTO nc_sociallogin_connect (uid, identifier) SELECT DISTINCT uid, CONCAT(&quot;Mailcow-&quot;, uid) FROM nc_users;

+<p>The Nextcloud instance can be updated easily with the web update mechanism. In the case of larger updates, there may be further changes to be made after the update. After the Nextcloud instance has been checked, problems are shown. This can be e.g. missing indices in the DB or similar.

+  <h1>Portainer</h1>
+
+<p>In order to enable Portainer, the docker-compose.yml and site.conf for Nginx must be modified.</p>
+<p>1. Create a new file <code>docker-compose.override.yml</code> in the mailcow-dockerized root folder and insert the following configuration
+<div class="highlight"><pre><span></span><code>version: &#39;2.1&#39;
+services:
+    portainer-mailcow:
+      image: portainer/portainer-ce
+      volumes:
+        - /var/run/docker.sock:/var/run/docker.sock
+        - ./data/conf/portainer:/data
+      restart: always
+      dns:
+        - 172.22.1.254
+      dns_search: mailcow-network
+      networks:
+        mailcow-network:
+          aliases:
+            - portainer
+</code></pre></div>
+2a. Create <code>data/conf/nginx/portainer.conf</code>:
+<div class="highlight"><pre><span></span><code>upstream portainer {
+  server portainer-mailcow:9000;
+}
+
+map $http_upgrade $connection_upgrade {
+  default upgrade;
+  &#39;&#39; close;
+}
+</code></pre></div></p>
+<p>2b. Insert a new location to the default mailcow site by creating the file <code>data/conf/nginx/site.portainer.custom</code>:
+<div class="highlight"><pre><span></span><code>  location /portainer/ {
+    proxy_http_version 1.1;
+    proxy_set_header Host              $http_host;   # required for docker client&#39;s sake
+    proxy_set_header X-Real-IP         $remote_addr; # pass on real client&#39;s IP
+    proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_read_timeout                 900;
+
+    proxy_set_header Connection &quot;&quot;;
+    proxy_buffers 32 4k;
+    proxy_pass http://portainer/;
+  }
+
+  location /portainer/api/websocket/ {
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection $connection_upgrade;
+    proxy_pass http://portainer/api/websocket/;
+  }
+</code></pre></div></p>
+<p>3. Apply your changes:
+<div class="highlight"><pre><span></span><code>docker-compose up -d &amp;&amp; docker-compose restart nginx-mailcow
+</code></pre></div></p>
+<p>Now you can simply navigate to https://${MAILCOW_HOSTNAME}/portainer/ to view your Portainer container monitoring page. You’ll then be prompted to specify a new password for the <strong>admin</strong> account. After specifying your password, you’ll then be able to connect to the Portainer UI.</p>

+Please note, that this preset only integrates the default addressbook (the one that's named "Personal Address Book" and can't be deleted). Additional addressbooks are currently not automatically detected but can be manually added within the roundecube settings.</p>
+<p>Enable the plugin by adding <code>carddav</code> to <code>$config['plugins']</code> in <code>rc/config/config.inc.php</code>.</p>
+<p>If you want to remove the default addressbooks (stored in the Roundcube database), so that only the CardDAV addressbooks are accessible, append <code>$config['address_book_type'] = '';</code> to the config file <code>data/web/rc/config/config.inc.php</code>.</p>
+<hr />
+<p>Optionally, you can add Roundcube's link to the mailcow Apps list.
+To do this, open or create <code>data/web/inc/vars.local.inc.php</code> and add the following code-block:</p>

+  <h1>Admin login to SOGo</h1>
+
+<p>This is an experimental feature that allows admins and domain admins to directly 
+log into SOGo as a mailbox user, without knowing the users password.</p>
+<p>For this, an additional link to SOGo is displayed in the mailbox list (mailcow UI).</p>
+<p>Multiple concurrent admin-logins to different mailboxes are also possible when using this feature.</p>
+<h2 id="enabling-the-feature">Enabling the feature<a class="headerlink" href="#enabling-the-feature" title="Permanent link">&para;</a></h2>
+<p>The feature is disabled by default. It can be enabled in the <code>mailcow.conf</code> by setting:
+<div class="highlight"><pre><span></span><code>ALLOW_ADMIN_EMAIL_LOGIN=y
+</code></pre></div>
+and recreating the affected containers with
+<div class="highlight"><pre><span></span><code>docker-compose up -d
+</code></pre></div></p>
+<h2 id="drawbacks-when-enabled">Drawbacks when enabled<a class="headerlink" href="#drawbacks-when-enabled" title="Permanent link">&para;</a></h2>
+<ul>
+<li>Each SOGo page-load and each Active-Sync request will cause an additional execution of an internal PHP script.
+This might impact load-times of SOGo / EAS.
+In most cases, this should not be noticeable but should be kept in mind if you face any performance issues.</li>
+<li>SOGo will not display a logout link for admin-logins, to login normally one has to logout from the mailcow UI so the PHP session is destroyed.</li>
+<li>Subscribing to another user's calendar or address book while logged in as admin does not work. Neither does inviting other users to calendar events. The page will reload when these things are attempted.</li>
+</ul>
+<h2 id="technical-details">Technical details<a class="headerlink" href="#technical-details" title="Permanent link">&para;</a></h2>
+<p>SOGoTrustProxyAuthentication option is set to YES which makes SOGo trust the x-webobjects-remote-user header.</p>
+<p>Dovecot will receive a random master-password which is valid for all mailboxes when used by the SOGo container.</p>
+<p>Clicking on the SOGo button in the mailbox list will open sogo-auth.php which checks permissions, sets session variables and redirects to the SOGo mailbox.</p>
+<p>Each SOGo, CardDAV, CalDAV and EAS http request will cause an additional, nginx internal auth_request call to sogo-auth.php with the following behavior:</p>
+<ul>
+<li>
+<p>If a basic_auth header is present, the script will validate the credentials in place of SOGo and provide the following headers:
+<code>x-webobjects-remote-user</code>, <code>Authorization</code> and <code>x-webobjects-auth-type</code>.</p>
+</li>
+<li>
+<p>If no basic_auth header is present, the script will check for an active mailcow admin session for the requested email user and provide the same headers but with the dovecot master password used in the <code>Authorization</code> header.</p>
+</li>
+<li>
+<p>If both fails the headers will be set empty, which makes SOGo use its standard authentication methods.</p>
+</li>
+</ul>
+<p>All of these options / behaviors are disabled if the <code>ALLOW_ADMIN_EMAIL_LOGIN</code> is not enabled in the config.</p>

+  <h1>Common Problems</h1>
+
+<p>Here we list common problems and possible solutions:</p>
+<h2 id="mail-loops-back-to-myself">Mail loops back to myself<a class="headerlink" href="#mail-loops-back-to-myself" title="Permanent link">&para;</a></h2>
+<p>Please check in your mailcow UI if you made the domain a <strong>backup MX</strong>:</p>
+<p><img alt="Check your MX Backup settings" src="../../assets/images/troubleshooting/mailcow-backupmx.png" /></p>
+<h2 id="i-can-receive-but-not-send-mails">I can receive but not send mails<a class="headerlink" href="#i-can-receive-but-not-send-mails" title="Permanent link">&para;</a></h2>
+<p>There are a lot of things that could prevent you from sending mail:</p>
+<ul>
+<li>Check if your IP address is on any blacklists. You could use <a href="http://www.dnsbl.info/">dnsbl.info</a> or any other similar service to check for your IP address.</li>
+<li>There are some consumer ISP routers out there, that block mail ports for non whitelisted domains. Please check if you can reach your server on the ports <code>465</code> or <code>587</code>:</li>
+</ul>
+<div class="highlight"><pre><span></span><code># telnet 74.125.133.27 465
+Trying 74.125.133.27...
+Connected to 74.125.133.27.
+Escape character is &#39;^]&#39;.
+</code></pre></div>
+<h2 id="my-mails-are-identified-as-spam">My mails are identified as Spam<a class="headerlink" href="#my-mails-are-identified-as-spam" title="Permanent link">&para;</a></h2>
+<p>Please read our guide on <a href="../../prerequisite/prerequisite-dns/">DNS configuration</a>.</p>
+<h2 id="docker-compose-throws-weird-errors">docker-compose throws weird errors<a class="headerlink" href="#docker-compose-throws-weird-errors" title="Permanent link">&para;</a></h2>
+<p>... like:</p>
+<ul>
+<li><code>ERROR: Invalid interpolation format ...</code></li>
+<li><code>AttributeError: 'NoneType' object has no attribute 'keys'</code>.</li>
+<li><code>ERROR: In file './docker-compose.yml' service 'version' doesn't have any configuration options</code>.</li>
+</ul>
+<p>When you encounter one or similar messages while trying to run mailcow: dockerized please check if you have the <strong>latest</strong> version of <strong>Docker</strong> and <strong>docker-compose</strong></p>
+<h2 id="container-xy-is-unhealthy">Container XY is unhealthy<a class="headerlink" href="#container-xy-is-unhealthy" title="Permanent link">&para;</a></h2>
+<p>This error tries to tell you that one of the (health) conditions for a certain container are not met. Therefore it can't be started. This can have several reasons, the most common one is an updated git clone but old docker image or vice versa.</p>
+<p>A wrong configured firewall could also cause such a failure. The containers need to be able to talk to each other over the network 172.22.1.1/24.</p>
+<p>It might also be wrongly linked file (i.e. SSL certificate) that prevents a crucial container (nginx) from starting, so always check your logs to get an idea where your problem is coming from.</p>
+<h2 id="address-already-in-use">Address already in use<a class="headerlink" href="#address-already-in-use" title="Permanent link">&para;</a></h2>
+<p>If you get an error message like:</p>
+<div class="highlight"><pre><span></span><code>ERROR: for postfix-mailcow  Cannot start service postfix-mailcow: driver failed programming external     connectivity on endpoint mailcowdockerized_postfix-mailcow_1: Error starting userland proxy: listen tcp 0.0.0.0:25: bind: address already in use
+</code></pre></div>
+<p>while trying to start / install mailcow: dockerized, make sure you've followed our section on the <a href="../prerequisite/prerequisite-system.en.md/#firewall-ports">prerequisites</a>.</p>
+<h2 id="xyz-cant-connect-to">XYZ can't connect to ...<a class="headerlink" href="#xyz-cant-connect-to" title="Permanent link">&para;</a></h2>
+<p>Please check your local firewall!
+Docker and iptables-based firewalls sometimes create conflicting rules, so disable the firewall on your host to determine whether your connection issues are caused by such conflicts. If they are, you need to manually create appropriate rules in your host firewall to permit the necessary connections.</p>
+<p>If you experience connection problems from home, please check your ISP router's firewall too, some of them block mail traffic on the <em>SMTP</em> (587) or <em>SMTPS</em> (465) ports. It could also be, that your ISP is blocking the ports for <em>SUBMISSION</em> (25).</p>
+<p>While Linux users can chose from a variety of tools<sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup> to check if a port is open, the Windows user has only the PowerShell command <code>Test-NetConnection -ComputerName host -Port port</code> available by default.</p>
+<p>To enable telnet on a Windows after Vista please check this <a href="https://social.technet.microsoft.com/wiki/contents/articles/910.windows-7-enabling-telnet-client.aspx">guide</a> or enter the following command in an terminal <strong>with administrator privileges</strong>:</p>
+<div class="highlight"><pre><span></span><code>dism /online /Enable-Feature /FeatureName:TelnetClient
+</code></pre></div>
+<h2 id="inotify-instance-limit-for-user-5000-uid-vmail-exceeded-see-453">Inotify instance limit for user 5000 (UID vmail) exceeded (<a href="https://github.com/mailcow/mailcow-dockerized/issues/453#issuecomment-314711232">see #453</a>)<a class="headerlink" href="#inotify-instance-limit-for-user-5000-uid-vmail-exceeded-see-453" title="Permanent link">&para;</a></h2>
+<p>Docker containers use the Docker hosts inotify limits. Setting them on your Docker host will pass them to the container.</p>
+<h2 id="dovecot-keeps-restarting-see-2672">Dovecot keeps restarting (see <a href="https://github.com/mailcow/mailcow-dockerized/issues/2672">#2672</a>)<a class="headerlink" href="#dovecot-keeps-restarting-see-2672" title="Permanent link">&para;</a></h2>
+<p>Check that you have at least the following files in <code>data/assets/ssl</code>:</p>
+<div class="highlight"><pre><span></span><code>cert.pem
+dhparams.pem
+key.pem
+</code></pre></div>
+<p>If <code>dhparams.pem</code> is missing, you can generate it with</p>
+<div class="highlight"><pre><span></span><code>openssl dhparam -out data/assets/ssl/dhparams.pem <span class="m">4096</span>

+<p>To view the logs of all mailcow: dockerized related containers, you can use <code>docker-compose logs</code> inside your mailcow-dockerized folder that contains your <code>mailcow.conf</code>. This is usually a bit much, but you could trim the output with <code>--tail=100</code> to the last 100 lines per container, or add a <code>-f</code> to follow the live output of all your services.</p>
+<p>To view the logs of a specific service you can use <code>docker-compose logs [options] $service_name</code></p>
+<div class="admonition info">
+<p class="admonition-title">Info</p>
+<p>The available options for the command <strong>docker-compose logs</strong> are:</p>
+<ul>
+<li><strong>--no-color</strong>: Produce monochrome output.</li>
+<li><strong>-f</strong>: Follow the log output.</li>
+<li><strong>-t</strong>: Show timestamps.</li>

+<p>If your server crashed and MariaDB logs an error similar to <code>[ERROR] mysqld: Aria recovery failed. Please run aria_chk -r on all Aria tables (*.MAI) and delete all aria_log.######## files</code> you may want to try the following to recover the database to a healthy state:</p>
+<p>Start the stack and wait until mysql-mailcow begins to report a restarting state. Check by running <code>docker-compose ps</code>.</p>
+<p>Now run the following commands:</p>
+<div class="highlight"><pre><span></span><code># Stop the stack, don&#39;t run &quot;down&quot;
+docker-compose stop
+# Run a bash in the stopped container as user mysql
+docker-compose run --rm --entrypoint &#39;/bin/sh -c &quot;gosu mysql bash&quot;&#39; mysql-mailcow
+# cd to the SQL data directory
+cd /var/lib/mysql
+# Run aria_chk
+aria_chk --check --force */*.MAI
+# Delete aria log files
+rm aria_log.*
+</code></pre></div>
+<p>Now run <code>docker-compose down</code> followed by <code>docker-compose up -d</code>.</p>

+
+<p>In case you encounter problems with your certificate, key or Let's Encrypt account, please try to reset the TLS assets:</p>
+<div class="highlight"><pre><span></span><code>source mailcow.conf
+docker-compose down
+rm -rf data/assets/ssl
+mkdir data/assets/ssl
+openssl req -x509 -newkey rsa:4096 -keyout data/assets/ssl-example/key.pem -out data/assets/ssl-example/cert.pem -days 365 -subj &quot;/C=DE/ST=NRW/L=Willich/O=mailcow/OU=mailcow/CN=${MAILCOW_HOSTNAME}&quot; -sha256 -nodes
+cp -n -d data/assets/ssl-example/*.pem data/assets/ssl/
+docker-compose up -d
+</code></pre></div>
+<p>This will stop mailcow, source the variables we need, create a self-signed certificate and start mailcow.</p>
+<p>If you use Let's Encrypt you should be careful as you will create a new account and a new set of certificates. You will run into a ratelimit sooner or later.</p>
+<p>Please also note that previous TLSA records will be invalid.</p>

+  <h1>Remove Persistent Data</h1>
+
+<p>You may want to remove a set of persistent data to resolve a conflict or to start over.</p>
+<p><code>mailcowdockerized</code> can vary and depends on your compose project name (if it's unchanged, <code>mailcowdockerized</code> is the correct value). If you are unsure about volume names, run <code>docker volume ls</code> for a full list.</p>
+<p>Delete a single volume:</p>
+<div class="highlight"><pre><span></span><code>docker volume rm mailcowdockerized_${VOLUME_NAME}
+</code></pre></div>
+<ul>
+<li>Remove volume <code>mysql-vol-1</code> to remove all MySQL data.</li>
+<li>Remove volume <code>redis-vol-1</code> to remove all Redis data.</li>
+<li>Remove volume <code>vmail-vol-1</code> to remove all contents of <code>/var/vmail</code> mounted to <code>dovecot-mailcow</code>.</li>
+<li>Remove volume <code>rspamd-vol-1</code> to remove all Rspamd data.</li>
+<li>Remove volume <code>crypt-vol-1</code> to remove all crypto data. This will render <strong>all mails</strong> unreadable.</li>
+</ul>
+<p>Alternatively, running <code>docker-compose down -v</code> will <strong>destroy all mailcow: dockerized volumes</strong> and delete any related containers and networks.</p>

+
+<p>A quick guide to deeply analyze a malfunctioning Rspamd.</p>
+<div class="highlight"><pre><span></span><code>docker-compose exec rspamd-mailcow bash
+
+if ! grep -qi &#39;apt-stable-asan&#39; /etc/apt/sources.list.d/rspamd.list; then
+  sed -i &#39;s/apt-stable/apt-stable-asan/i&#39; /etc/apt/sources.list.d/rspamd.list
+fi
+
+apt-get update ; apt-get upgrade rspamd
+
+nano /docker-entrypoint.sh
+
+# Before &quot;exec &quot;$@&quot;&quot; add the following lines:
+
+export G_SLICE=always-malloc
+export ASAN_OPTIONS=new_delete_type_mismatch=0:detect_leaks=1:detect_odr_violation=0:log_path=/tmp/rspamd-asan:quarantine_size_mb=2048:malloc_context_size=8:fast_unwind_on_malloc=0
+</code></pre></div>
+<p>Restart Rspamd: <code>docker-compose restart rspamd-mailcow</code></p>
+<p>Your memory consumption will increase by a lot, it will also steadily grow, which is not related to a possible memory leak you are looking for.</p>
+<p>Leave the container running for a few minutes, hours or days (it should match the time you usually wait for the leak to "happen") and restart it: <code>docker-compose restart rspamd-mailcow</code>.</p>
+<p>Now enter the container by running <code>docker-compose exec rspamd-mailcow bash</code>, change the directory to /tmp and copy the asan Files to your desired location or upload them via termbin.com (<code>cat /tmp/rspamd-asan.* | nc termbin.com 9999</code>).</p>

 <p>We decided to switch this parameter back to <code>no</code> and allow a user to specify which recipient address triggers a vacation reply. The triggering recipients can also be configured in SOGos autoresponder feature.</p>

 <p>Solr is used for setups with memory &gt;= 3.5 GiB to provide full-text search in Dovecot.</p>
 <p>Please be aware that applications like Solr <em>may</em> need maintenance from time to time.</p>
 <p>Besides that, Solr will eat a lot of RAM, depending on the usage of your server. Please avoid it on machines with less than 3 GB RAM.</p>
 <p>The default heap size (1024 M) is defined in mailcow.conf.</p>
 <p>Since we run in Docker and create our containers with the "restart: always" flag, a oom situation will at least only trigger a restart of the container.</p>

+<p>The Solr replacement Xapian is currently in the development/testing phase.</p>
+<p>Xapian is much more efficient than Solr because it is not based on Java.</p>
+<p>Xapian is also not as vulnerable to security vulnerabilities (which often occur in Java applications).</p>
+<p>The most serious difference between the two FTS is that Xapian (unlike Solr) no longer needs an extra container but from then on runs directly in Dovecot (as a plugin).</p>
+<p>If you want to know more about the Xapian plugin look <a href="https://github.com/grosjo/fts-xapian">here</a>.</p>

+<p>For DNS blacklist lookups and DNSSEC.</p>
+<p>Most systems use either a public or a local caching DNS resolver.
+That's a very bad idea when it comes to filter spam using DNS-based black hole lists (DNSBL) or similar technics.
+Most if not all providers apply a rate limit based on the DNS resolver that is used to query their service.
+Using a public resolver like Googles 4x8, OpenDNS or any other shared DNS resolver like your ISPs will hit that limit very soon.</p>

-<p>Administrators and domain administrators can edit mailboxes to allow specific users to send as other mailbox users ("delegate" them).</p>
-<p>You can choose between mailbox users or completely disable the sender check for domains.</p>
-<h3 id="sogo-mail-from-addresses">SOGo "mail from" addresses<a class="headerlink" href="#sogo-mail-from-addresses" title="Permanent link">&para;</a></h3>
-<p>Mailbox users can, obviously, select their own mailbox address, as well as all alias addresses and aliases that exist through alias domains.</p>
-<p>If you want to select another <em>existing</em> mailbox user as your "mail from" address, this user has to delegate you access through SOGo (see SOGo documentation). Moreover a mailcow (domain) administrator
-needs to grant you access as described above.</p>

+  <h1>Sender and receiver model</h1>
+
+<p>When a mailbox is created, a user is allowed to send mail from and receive mail for his own mailbox address.</p>
+<pre><code>Mailbox me@example.org is created. example.org is a primary domain.
+Note: a mailbox cannot be created in an alias domain.
+
+me@example.org is only known as me@example.org.
+me@example.org is allowed to send as me@example.org.
+</code></pre>
+<p>We can add an alias domain for example.org:</p>
+<pre><code>Alias domain alias.com is added and assigned to primary domain example.org.
+me@example.org is now known as me@example.org and me@alias.com.
+me@example.org is now allowed to send as me@example.org and me@alias.com.
+</code></pre>
+<p>We can add aliases for a mailbox to receive mail for and to send from this new address.</p>
+<p>It is important to know, that you are not able to receive mail for <code>my-alias@my-alias-domain.tld</code>. You would need to create this particular alias.</p>
+<pre><code>me@example.org is assigned the alias alias@example.org
+me@example.org is now known as me@example.org, me@alias.com, alias@example.org
+
+me@example.org is NOT known as alias@alias.com.
+</code></pre>
+<p>Please note that this does not apply to catch-all aliases:</p>
+<pre><code>Alias domain alias.com is added and assigned to primary domain example.org
+me@example.org is assigned the catch-all alias @example.org
+me@example.org is still just known as me@example.org, which is the only available send-as option
+
+Any email send to alias.com will match the catch-all alias for example.org
+</code></pre>
+<p>Administrators and domain administrators can edit mailboxes to allow specific users to send as other mailbox users ("delegate" them).</p>
+<p>You can choose between mailbox users or completely disable the sender check for domains.</p>
+<h3 id="sogo-mail-from-addresses">SOGo "mail from" addresses<a class="headerlink" href="#sogo-mail-from-addresses" title="Permanent link">&para;</a></h3>
+<p>Mailbox users can, obviously, select their own mailbox address, as well as all alias addresses and aliases that exist through alias domains.</p>
+<p>If you want to select another <em>existing</em> mailbox user as your "mail from" address, this user has to delegate you access through SOGo (see SOGo documentation). Moreover a mailcow (domain) administrator
+needs to grant you access as described above.</p>

In Docker the containerized application (PID 1) writes its output to stdout. For real one-application containers this works just fine. Run docker-compose logs --help to learn more. Some containers log or stream to multiple destinations. No container will keep persistent logs in it. Containers are transient items! In the end, every line of logs will reach the Docker daemon - unfiltered. The default logging driver is \"json\" . Filtered logs \u00b6 Some logs are filtered and written to Redis keys but also streamed to a Redis channel. The Redis channel is used to stream logs with failed authentication attempts to be read by netfilter-mailcow. The Redis keys are persistent and will keep 10000 lines of logs for the web UI. This mechanism makes it possible to use whatever Docker logging driver you want to, without losing the ability to read logs from the UI or ban suspicious clients with netfilter-mailcow.

Important information, please read them carefully! Info If you plan to use a reverse proxy and want to use another server name that is not MAILCOW_HOSTNAME, you need to read Adding additional server names for mailcow UI at the bottom of this page. Warning Make sure you run generate_config.sh before you enable any site configuration examples below. The script generate_config.sh copies snake-oil certificates to the correct location, so the services will not fail to start due to missing files. Warning If you enable TLS SNI ( ENABLE_TLS_SNI in mailcow.conf), the certificate paths in your reverse proxy must match the correct paths in data/assets/ssl/{hostname}. The certificates will be split into data/assets/ssl/{hostname1,hostname2,etc} and therefore will not work when you copy the examples from below pointing to data/assets/ssl/cert.pem etc. Info Using the site configs below will forward ACME requests to mailcow and let it handle certificates itself. The downside of using mailcow as ACME client behind a reverse proxy is, that you will need to reload your webserver after acme-mailcow changed/renewed/created the certificate. You can either reload your webserver daily or write a script to watch the file for changes. On many servers logrotate will reload the webserver daily anyway. If you want to use a local certbot installation, you will need to change the SSL certificate parameters accordingly. Make sure you run a post-hook script when you decide to use external ACME clients. You will find an example at the bottom of this page. 2.

For this section we'll assume you have your Traefik 2 [certificatesresolvers] properly configured on your traefik configuration file, and also using acme, also, the following example uses Lets Encrypt, but feel free to change it to your own cert resolver. You can find a basic Traefik 2 toml config file with all the above implemented which can be used for this example here traefik.toml if you need one, or a hint on how to adapt your config.

Now, there's only one thing left to do, which is setup the certs so that the mail services can use them as well, since Traefik 2 uses an acme v2 format to save ALL the license from all the domains we have, we'll need to find a way to dump the certs, lucky we have this tiny container which grabs the acme.json file trough a volume, and a variable DOMAIN=example.org , and with these, the container will output the cert.pem and key.pem files, for this we'll simply run the traefik-certs-dumper container binding the /traefik volume to the folder where our acme.json is saved, bind the /output volume to our mailcow data/assets/ssl/ folder, and set up the DOMAIN=example.org variable to the domain we want the certs dumped from. This container will watch over the acme.json file for any changes, and regenerate the cert.pem and key.pem files directly into data/assets/ssl/ being the path binded to the container's /output path.

Validation errors and how to skip validation \u00b6 You can skip the IP verification by setting SKIP_IP_CHECK=y in mailcow.conf (no quotes). Be warned that a misconfiguration will get you ratelimited by Let's Encrypt! This is primarily useful for multi-IP setups where the IP check would return the incorrect source IP address. Due to using dynamic IPs for acme-mailcow, source NAT is not consistent over restarts. If you encounter problems with \"HTTP validation\", but your IP address confirmation succeeds, you are most likely using firewalld, ufw or any other firewall, that disallows connections from br-mailcow to your external interface. Both firewalld and ufw disallow this by default. It is often not enough to just stop these firewall services. You'd need to stop mailcow ( docker-compose down ), stop the firewall service, flush the chains and restart Docker. You can also skip this validation method by setting SKIP_HTTP_VERIFICATION=y in \"mailcow.conf\". Be warned that this is discouraged. In most cases, the HTTP verification is skipped to workaround unknown NAT reflection issues, which are not resolved by ignoring this specific network misconfiguration. If you encounter problems generating TLSA records in the DNS overview within mailcow, you are most likely having issues with NAT reflection you should fix. If you changed a SKIP_* parameter, run docker-compose up -d to apply your changes. Disable Let's Encrypt \u00b6 Disable Let's Encrypt completely \u00b6 Set SKIP_LETS_ENCRYPT=y in \"mailcow.conf\" and recreate \"acme-mailcow\" by running docker-compose up -d . Skip all names but ${MAILCOW_HOSTNAME} \u00b6 Add ONLY_MAILCOW_HOSTNAME=y to \"mailcow.conf\" and recreate \"acme-mailcow\" by running docker-compose up -d . The Let's Encrypt subjectAltName limit of 100 domains \u00b6 Let's Encrypt currently has a limit of 100 Domain Names per Certificate . By default, \"acme-mailcow\" will create a single SAN certificate for all validated domains (see the first section and Additional domain names ). This provides best compatibility but means the Let's Encrypt limit exceeds if you add too many domains to a single mailcow installation. To solve this, you can configure ENABLE_SSL_SNI to generate: A main server certificate with MAILCOW_HOSTNAME and all fully qualified domain names in the ADDITIONAL_SAN config One additional certificate for each domain found in the database with autodiscover. , autoconfig. and any other ADDITIONAL_SAN configured in this format (subdomain.*). Limitations: A certificate name ADDITIONAL_SAN=test.example.com will be added as SAN to the main certificate. A separate certificate/key pair will not be generated for this format. Postfix, Dovecot and Nginx will then serve these certificates with SNI. Set ENABLE_SSL_SNI=y in \"mailcow.conf\" and recreate \"acme-mailcow\" by running docker-compose up -d . Warning Not all clients support SNI, see Dovecot documentation or Wikipedia . You should make sure these clients use the MAILCOW_HOSTNAME for secure connections if you enable this feature. Here is an example: MAILCOW_HOSTNAME=server.email.tld ADDITIONAL_SAN=webmail.email.tld,mail.* Mailcow email domains: \"domain1.tld\" and \"domain2.tld\" The following certificates will be generated: server.email.tld, webmail.email.tld -> this is the default certificate, all clients can connect with these domains mail.domain1.tld, autoconfig.domain1.tld, autodiscover.domain1.tld -> individual certificate for domain1.tld, cannot be used by clients without SNI support mail.domain2.tld, autoconfig.domain2.tld, autodiscover.domain2.tld -> individual certificate for domain2.tld, cannot be used by clients without SNI support How to use your own certificate \u00b6 Make sure you disable mailcows internal LE client (see above). To use your own certificates, just save the combined certificate (containing the certificate and intermediate CA/CA if any) to data/assets/ssl/cert.pem and the corresponding key to data/assets/ssl/key.pem . IMPORTANT: Do not use symbolic links! Make sure you copy the certificates and do not link them to data/assets/ssl . Restart affected services afterwards: docker restart $(docker ps -qaf name=postfix-mailcow) docker restart $(docker ps -qaf name=nginx-mailcow) docker restart $(docker ps -qaf name=dovecot-mailcow) See Post-hook script for non-mailcow ACME clients for a full example script. Test against staging ACME directory \u00b6 Edit mailcow.conf and add LE_STAGING=y . Run docker-compose up -d to activate your changes. Custom directory URL \u00b6 Edit mailcow.conf and add the corresponding directory URL to the new variable DIRECTORY_URL : DIRECTORY_URL=https://acme-custom-v9000.api.letsencrypt.org/directory You cannot use LE_STAGING with DIRECTORY_URL . If both are set, only LE_STAGING is used. Run docker-compose up -d to activate your changes. Check your configuration \u00b6 Run docker-compose logs acme-mailcow to find out why a validation fails. To check if nginx serves the correct certificate, simply use a browser of your choice and check the displayed certificate.

It is highly recommended to use the commands below to install docker-compose . Package managers (e.g. apt , yum ) likely won't give you the correct version. Note: This command downloads docker-compose from the official Docker Github repository and is a safe method. The snippet will determine the latest supported version by mailcow. In almost all cases this is the latest version available (exceptions are broken releases or major changes not yet supported by mailcow). curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose Please use the latest Docker engine available and do not use the engine that ships with your distros repository. 1.1. On SELinux enabled systems, e.g. CentOS 7: Check if \"container-selinux\" package is present on your system: rpm -qa | grep container-selinux If the above command returns an empty or no output, you should install it via your package manager. Check if docker has SELinux support enabled: docker info | grep selinux If the above command returns an empty or no output, create or edit /etc/docker/daemon.json and add \"selinux-enabled\": true . Example file content: { \"selinux-enabled\": true } Restart the docker daemon and verify SELinux is now enabled. This step is required to make sure mailcows volumes are properly labeled as declared in the compose file. If you are interested in how this works, you can check out the readme of https://github.com/containers/container-selinux which links to a lot of useful information on that topic. 2. Clone the master branch of the repository, make sure your umask equals 0022. Please clone the repository as root user and also control the stack as root. We will modify attributes - if necessary - while boostrapping the containers automatically and make sure everything is secured. The update.sh script must therefore also be run as root. It might be necessary to change ownership and other attributes of files you will otherwise not have access to. We drop permissions for every exposed application and will not run an exposed service as root! Controlling the Docker daemon as non-root user does not give you additional security. The unprivileged user will spawn the containers as root likewise. The behaviour of the stack is identical. $ su # umask 0022 # <- Verify it is 0022 # cd /opt # git clone https://github.com/mailcow/mailcow-dockerized # cd mailcow-dockerized 3. Generate a configuration file. Use a FQDN ( host.domain.tld ) as hostname when asked. ./generate_config.sh 4. Change configuration if you want or need to. nano mailcow.conf If you plan to use a reverse proxy, you can, for example, bind HTTPS to 127.0.0.1 on port 8443 and HTTP to 127.0.0.1 on port 8080. You may need to stop an existing pre-installed MTA which blocks port 25/tcp. See this chapter to learn how to reconfigure Postfix to run besides mailcow after a successful installation. Some updates modify mailcow.conf and add new parameters. It is hard to keep track of them in the documentation. Please check their description and, if unsure, ask at the known channels for advise. 4.1. Users with a MTU not equal to 1500 (e.g. OpenStack): Whenever you run into trouble and strange phenomena, please check your MTU. Edit docker-compose.yml and change the network settings according to your MTU. Add the new driver_opts parameter like this: networks: mailcow-network: ... driver_opts: com.docker.network.driver.mtu: 1450 ... 4.2. Users without an IPv6 enabled network on their host system: Enable IPv6. Finally. If you do not have an IPv6 enabled network on your host and you don't care for a better internet (thehe), it is recommended to disable IPv6 for the mailcow network to prevent unforeseen issues. 5. Pull the images and run the compose file. The parameter -d will start mailcow: dockerized detached: docker-compose pull docker-compose up -d Done! You can now access https://${MAILCOW_HOSTNAME} with the default credentials admin + password moohoo . Info If you are not using mailcow behind a reverse proxy, you should redirect all HTTP requests to HTTPS . The database will be initialized right after a connection to MySQL can be established.

A domain administror has not access to sync jobs but can login as mailbox user When logging in as mailbox user, he does not gain access to sync jobs, even if the given mailbox user has access when logging in directly 2. A domain administror has access to sync jobs and can login as mailbox user The mailbox user he tries to login as has not access to sync jobs The domain administrator, now logged in as mailbox user, inherits its permission to the mailbox user and can access sync jobs 3.

Due to it's deduplication capabilities you can store a great number of backups without wasting large amounts of disk space. This allows you to run backups in very short intervals to ensure minimal data loss when the need arises to recover data from a backup. This document guides you through the process to enable continuous backups for mailcow with borgmatic. The borgmatic functionality is provided by the borgmatic Docker image by b3vis . Check out the README in that repository to find out about the other options (such as push notifications) that are available. This guide only covers the basics. Setting up borgmatic \u00b6 Create or amend docker-compose.override.yml \u00b6 In the mailcow-dockerized root folder create or edit docker-compose.override.yml and insert the following configuration: version : '2.1' services : borgmatic-mailcow : image : b3vis/borgmatic hostname : mailcow restart : always dns : ${IPV4_NETWORK:-172.22.1}.254 volumes : - vmail-vol-1:/mnt/source/vmail:ro - crypt-vol-1:/mnt/source/crypt:ro - redis-vol-1:/mnt/source/redis:ro,z - rspamd-vol-1:/mnt/source/rspamd:ro,z - postfix-vol-1:/mnt/source/postfix:ro,z - mysql-socket-vol-1:/var/run/mysqld/:z - borg-config-vol-1:/root/.config/borg:Z - borg-cache-vol-1:/root/.cache/borg:Z - ./data/conf/borgmatic/etc:/etc/borgmatic.d:Z - ./data/conf/borgmatic/ssh:/root/.ssh:Z environment : - TZ=${TZ} - BORG_PASSPHRASE=YouBetterPutSomethingRealGoodHere networks : mailcow-network : aliases : - borgmatic volumes : borg-cache-vol-1 : borg-config-vol-1 : Ensure that you change the BORG_PASSPHRASE to a secure passphrase of your choosing. For security reasons we mount the maildir as read-only. If you later want to restore data you will need to remove the ro flag prior to restoring the data. This is described in the section on restoring backups. Create data/conf/borgmatic/etc/config.yaml \u00b6 Next, we need to create the borgmatic configuration. source mailcow.conf cat <<EOF > data/conf/borgmatic/etc/config.yaml location: source_directories: - /mnt/source repositories: - user@rsync.net:mailcow exclude_patterns: - '/mnt/source/postfix/public/' - '/mnt/source/postfix/private/' - '/mnt/source/rspamd/rspamd.sock' retention: keep_hourly: 24 keep_daily: 7 keep_weekly: 4 keep_monthly: 6 hooks: mysql_databases: - name: ${DBNAME} username: ${DBUSER} password: ${DBPASS} options: --default-character-set=utf8mb4 EOF Creating the file in this way ensures the correct MySQL credentials are pulled in from mailcow.conf . This file is a minimal example for using borgmatic with an account user on the cloud storage provider rsync.net for a repository called mailcow (see repositories setting). It will backup both the maildir and MySQL database, which is all you should need to restore your mailcow setup after an incident. The retention settings will keep one archive for each hour of the past 24 hours, one per day of the week, one per week of the month and one per month of the past half year. Check the borgmatic documentation on how to use other types of repositories or configuration options. If you choose to use a local filesystem as a backup destination make sure to mount it into the container. The container defines a volume called /mnt/borg-repository for this purpose. Note If you do not use rsync.net you can most likely drop the remote_path element from your config. Create a crontab \u00b6 Create a new text file in data/conf/borgmatic/etc/crontab.txt with the following content: 14 * * * * PATH=$PATH:/usr/bin /usr/bin/borgmatic --stats -v 0 2>&1 This file expects crontab syntax. The example shown here will trigger the backup to run every hour at 14 minutes past the hour and log some nice stats at the end. Place SSH keys in folder \u00b6 Place the SSH keys you intend to use for remote repository connections in data/conf/borgmatic/ssh . OpenSSH expects the usual id_rsa , id_ed25519 or similar to be in this directory. Ensure the file is chmod 600 and not world readable or OpenSSH will refuse to use the SSH key. Bring up the container \u00b6 For the next step we need the container to be up and running in a configured state. To do that run: docker-compose up -d Initialize the repository \u00b6 By now your borgmatic container is up and running, but the backups will currently fail due to the repository not being initialized. To initialize the repository run: docker-compose exec borgmatic-mailcow borgmatic init --encryption repokey-blake2 You will be asked you to authenticate the SSH host key of your remote repository server. See if it matches and confirm the prompt by entering yes . The repository will be initialized with the passphrase you set in the BORG_PASSPHRASE environment variable earlier. When using any of the repokey encryption methods the encryption key will be stored in the repository itself and not on the client, so there is no further action required in this regard. If you decide to use a keyfile instead of a repokey make sure you export the key and back it up separately. Check the Exporting Keys section for how to retrieve the key. Restart container \u00b6 Now that we finished configuring and initializing the repository restart the container to ensure it is in a defined state: docker-compose restart borgmatic-mailcow Restoring from a backup \u00b6 Restoring a backup assumes you are starting off with a fresh installation of mailcow, and you currently do not have any custom data in your maildir or your mailcow database. Restore maildir \u00b6 Warning Doing this will overwrite files in your maildir! Do not run this unless you actually intend to recover mail files from a backup. If you use SELinux in Enforcing mode If you are using mailcow on a host with SELinux in Enforcing mode you will have to temporarily disable it during extraction of the archive as the mailcow setup labels the vmail volume as private, belonging to the dovecot container exclusively. SELinux will (rightfully) prevent any other container, such as the borgmatic container, from writing to this volume. Before running a restore you must make the vmail volume writeable in docker-compose.override.yml by removing the ro flag from the volume. Then you can use the following command to restore the maildir from a backup: docker-compose exec borgmatic-mailcow borgmatic extract --path mnt/source --archive latest Alternatively you can specify any archive name from the list of archives (see Listing all available archives ) Restore MySQL \u00b6 Warning Running this command will delete and recreate the mailcow database! Do not run this unless you actually intend to recover the mailcow database from a backup. To restore the MySQL database from the latest archive use this command: docker-compose exec borgmatic-mailcow borgmatic restore --archive latest Alternatively you can specify any archive name from the list of archives (see Listing all available archives ) After restoring \u00b6 After restoring you need to restart mailcow. If you disabled SELinux enforcing mode now would be a good time to re-enable it. To restart mailcow use the follwing command: docker-compose down && docker-compose up -d If you use SELinux this will also trigger the re-labeling of all files in your vmail volume. Be patient, as this may take a while if you have lots of files. Useful commands \u00b6 Manual archiving run (with debugging output) \u00b6 docker-compose exec borgmatic-mailcow borgmatic -v 2 Listing all available archives \u00b6 docker-compose exec borgmatic-mailcow borgmatic list Break lock \u00b6 When borg is interrupted during an archiving run it will leave behind a stale lock that needs to be cleared before any new operations can be performed: docker-compose exec borgmatic-mailcow borg break-lock user@rsync.net:mailcow Where user@rsync.net:mailcow is the URI to your repository. Now would be a good time to do a manual archiving run to ensure it can be successfully performed. Exporting keys \u00b6 When using any of the keyfile methods for encryption you MUST take care of backing up the key files yourself. The key files are generated when you initialize the repository. The repokey methods store the key file within the repository, so a manual backup isn't as essential. Note that in either case you also must have the passphrase to decrypt any archives. To fetch the keyfile run: docker-compose exec borgmatic-mailcow borg key export --paper user@rsync.net:mailcow Where user@rsync.net:mailcow is the URI to your repository.","title":"Borgmatic Backup"},{"location":"third_party-borgmatic/#borgmatic-backup","text":"","title":"Borgmatic Backup"},{"location":"third_party-borgmatic/#introduction","text":"Borgmatic is a great way to run backups on your Mailcow setup as it securely encrypts your data and is extremely easy to set up.

Please post issues, questions and improvements in the issue tracker there. Warning mailcow is not responsible for any data loss, hardware damage or broken keyboards. This guide comes without any warranty. Make backups before starting, 'coze: No backup no pity! Introduction \u00b6 This guide aims to install and configure mailcow-dockerized with docker-mailman and to provide some useful scripts. An essential condition is, to preserve mailcow and Mailman in their own installations for independent updates. There are some guides and projects on the internet, but they are not up to date and/or incomplete in documentation or configuration. This guide is based on the work of: mailcow-mailman3-dockerized by Shadowghost mailman-mailcow-integration After finishing this guide, mailcow-dockerized and docker-mailman will run and Apache as a reverse proxy will serve the web frontends. The operating system used is an Ubuntu 20.04 LTS . Installation \u00b6 This guide is based on different steps: DNS setup Install Apache as a reverse proxy Obtain SSL certificates with Let's Encrypt Install mailcow with Mailman integration Install Mailman \ud83c\udfc3 Run DNS setup \u00b6 Most of the configuration is covered by mailcow s DNS setup . After finishing this setup add another subdomain for Mailman , e.g. lists.example.org that points to the same server: # Name Type Value lists IN A 1.2.3.4 lists IN AAAA dead:beef Install Apache as a reverse proxy \u00b6 Install Apache , e.g. with this guide from Digital Ocean : How To Install the Apache Web Server on Ubuntu 20.04 . Activate certain Apache modules (as root or sudo ): a2enmod rewrite proxy proxy_http headers ssl wsgi proxy_uwsgi http2 Maybe you have to install further packages to get these modules. This PPA by Ond\u0159ej Sur\u00fd may help you. vHost configuration \u00b6 Copy the mailcow.conf and the mailman.conf in the Apache conf folder sites-available (e.g. under /etc/apache2/sites-available ). Change in mailcow.conf : - MAILCOW_HOSTNAME to your MAILCOW_HOSTNAME Change in mailman.conf : - MAILMAN_DOMAIN to your Mailman domain (e.g. lists.example.org ) Don't activate the configuration, as the ssl certificates and directories are missing yet. Obtain SSL certificates with Let's Encrypt \u00b6 Check if your DNS config is available over the internet and points to the right IP addresses, e.g. with MXToolBox : https://mxtoolbox.com/SuperTool.aspx?action=a%3aMAILCOW_HOSTNAME https://mxtoolbox.com/SuperTool.aspx?action=aaaa%3aMAILCOW_HOSTNAME https://mxtoolbox.com/SuperTool.aspx?action=a%3aMAILMAN_DOMAIN https://mxtoolbox.com/SuperTool.aspx?action=aaaa%3aMAILMAN_DOMAIN Install certbot (as root or sudo ): apt install certbot Get the desired certificates (as root or sudo ): certbot certonly -d mailcow_HOSTNAME certbot certonly -d MAILMAN_DOMAIN Install mailcow with Mailman integration \u00b6 Install mailcow \u00b6 Follow the mailcow installation . Omit step 5 and do not pull and up with docker-compose ! Configure mailcow \u00b6 This is also Step 4 in the official mailcow installation ( nano mailcow.conf ). So change to your needs and alter the following variables: HTTP_PORT=18080 # don't use 8080 as mailman needs it HTTP_BIND=127.0.0.1 # HTTPS_PORT=18443 # you may use 8443 HTTPS_BIND=127.0.0.1 # SKIP_LETS_ENCRYPT=y # reverse proxy will do the SSL termination SNAT_TO_SOURCE=1.2.3.4 # change this to your IPv4 SNAT6_TO_SOURCE=dead:beef # change this to your global IPv6 Add Mailman integration \u00b6 Create the file /opt/mailcow-dockerized/docker-compose.override.yml (e.g. with nano ) and add the following lines: version: '2.1' services: postfix-mailcow: volumes: - /opt/mailman:/opt/mailman networks: - docker-mailman_mailman networks: docker-mailman_mailman: external: true The additional volume is used by Mailman to generate additional config files for mailcow postfix . The external network is build and used by Mailman . mailcow needs it to deliver incoming list mails to Mailman . Create the file /opt/mailcow-dockerized/data/conf/postfix/extra.cf (e.g. with nano ) and add the following lines: # mailman recipient_delimiter = + unknown_local_recipient_reject_code = 550 owner_request_special = no local_recipient_maps = regexp:/opt/mailman/core/var/data/postfix_lmtp, proxy:unix:passwd.byname, $alias_maps virtual_mailbox_maps = proxy:mysql:/opt/postfix/conf/sql/mysql_virtual_mailbox_maps.cf, regexp:/opt/mailman/core/var/data/postfix_lmtp transport_maps = pcre:/opt/postfix/conf/custom_transport.pcre, pcre:/opt/postfix/conf/local_transport, proxy:mysql:/opt/postfix/conf/sql/mysql_relay_ne.cf, proxy:mysql:/opt/postfix/conf/sql/mysql_transport_maps.cf, regexp:/opt/mailman/core/var/data/postfix_lmtp relay_domains = proxy:mysql:/opt/postfix/conf/sql/mysql_virtual_relay_domain_maps.cf, regexp:/opt/mailman/core/var/data/postfix_domains relay_recipient_maps = proxy:mysql:/opt/postfix/conf/sql/mysql_relay_recipient_maps.cf, regexp:/opt/mailman/core/var/data/postfix_lmtp As we overwrite mailcow postfix configuration here, this step may break your normal mail transports. Check the original configuration files if anything changed. SSL certificates \u00b6 As we proxying mailcow , we need to copy the SSL certificates into the mailcow file structure. This task will do the script renew-ssl.sh for us: Copy the file to /opt/mailcow-dockerized Change mailcow_HOSTNAME to your mailcow hostname Make it executable ( chmod a+x renew-ssl.sh ) Do not run it yet, as we first need Mailman You have to create a cronjob , so that new certificates will be copied. Execute as root or sudo : crontab -e To run the script every day at 5am, add: 0 5 * * * /opt/mailcow-dockerized/renew-ssl.sh Install Mailman \u00b6 Basicly follow the instructions at docker-mailman .

Disclaimer : This is not officially maintained nor supported by the mailcow project nor its contributors. No warranty or support is being provided, however you're free to open issues on GitHub for filing a bug or provide further ideas. GitHub repo can be found here . Info Support for domain wildcards were implemented in Piler 1.3.10 which was released on 03.01.2021. Prior versions basically do work, but after logging in you won't see emails sent from or to the domain alias. (e.g. when @example.com is an alias for admin@example.com ) The problem to solve \u00b6 mailpiler offers the authentication based on IMAP, for example: $config['ENABLE_IMAP_AUTH'] = 1; $config['IMAP_HOST'] = 'mail.example.com'; $config['IMAP_PORT'] = 993; $config['IMAP_SSL'] = true; So when you log in using patrik@example.com , you will only see delivered emails sent from or to this specific email address. When additional aliases are defined in mailcow, like team@example.com , you won't see emails sent to or from this email address even the fact you're a recipient of mails sent to this alias address. By hooking into the authentication process of mailpiler, we are able to get required data via the mailcow API during login. This fires API requests to the mailcow API (requiring read-only API access) to read out the aliases your email address participates and also the \"Name\" of the mailbox specified to display it on the top-right of mailpiler after login. Permitted email addresses can be seen in the mailpiler settings top-right after logging in. Info This is only pulled once during the authentication process. The authorized aliases and the realname are valid for the whole duration of the user session as mailpiler sets them in the session data. If user is removed from specific alias, this will only take effect after next login. The solution \u00b6 Note: File paths might vary depending on your setup. Requirements \u00b6 A working mailcow instance A working mailpiler instance ( You can find an installation guide here , check supported versions here ) An mailcow API key (read-only works just fine): Configuration & Details - Access - Read-Only Access . Don't forget to allow API access from your mailpiler IP. Warning As mailpiler authenticates against mailcow, our IMAP server, failed logins of users or bots might trigger a block for your mailpiler instance. Therefore you might want to consider whitelisting the IP address of the mailpiler instance within mailcow: Configuration & Details - Configuration - Fail2ban parameters - Whitelisted networks/hosts . Setup \u00b6 Set the custom query function of mailpiler and append this to /usr/local/etc/piler/config-site.php : $config['MAILCOW_API_KEY'] = 'YOUR_READONLY_API_KEY'; $config['MAILCOW_SET_REALNAME'] = true; // when not specified, then default is false $config['CUSTOM_EMAIL_QUERY_FUNCTION'] = 'query_mailcow_for_email_access'; include('auth-mailcow.php'); You can also change the mailcow hostname, if required: $config['MAILCOW_HOST'] = 'mail.domain.tld'; // defaults to $config['IMAP_HOST'] Download the PHP file with the functions from the GitHub repo : curl -o /usr/local/etc/piler/auth-mailcow.php https://raw.githubusercontent.com/patschi/mailpiler-mailcow-integration/master/auth-mailcow.php Done! Make sure to re-login with your IMAP credentials for changes to take effect. If it doesn't work, most likely something's wrong with the API query itself.

Both WebAuthn and Yubi OTP work well with the fantastic Yubikey . While Yubi OTP needs an active internet connection and an API ID + key, WebAuthn will work with any Fido Security Key out of the box, but can only be used when mailcow is accessed over HTTPS. WebAuthn and Yubi OTP support multiple keys per user. As the third TFA method mailcow uses TOTP: time-based one-time passwords. Those passwords can be generated with apps like \"Google Authenticator\" after initially scanning a QR code or entering the given secret manually. As administrator you are able to temporary disable a domain administrators TFA login until they successfully logged in. The key used to login will be displayed in green, while other keys remain grey. Information on how to remove 2FA can be found here . Yubi OTP \u00b6 The Yubi API ID and Key will be checked against the Yubico Cloud API. When setting up TFA you will be asked for your personal API account for this key. The API ID, API key and the first 12 characters (your YubiKeys ID in modhex) are stored in the MySQL table as secret. Example setup \u00b6 First of all, the YubiKey must be configured for use as an OTP Generator. To do this, download the YubiKey Manager from the Yubico website: here In the following you configure the YubiKey for OTP. Via the menu item Applications -> OTP and a click on the Configure button. In the following menu select Credential Type -> Yubico OTP and click on Next . Set a checkmark in the Use serial checkbox, generate a Private ID and a Secret key via the buttons. So that the YubiKey can be validated later, the checkmark in the Upload checkbox must also be set and then click on Finish . Now a new browser window will open in which you have to enter an OTP of your YubiKey at the bottom of the form (click on the field and then tap on your YubiKey). Confirm the captcha and upload the information to the Yubico server by clicking 'Upload'. The processing of the data will take a moment. After the generation was successful, you will be shown a Client ID and a Secret key , make a note of this information in a safe place. Now you can select Yubico OTP authentication from the dropdown menu in the mailcow UI on the start page under Access -> Two-factor authentication . In the dialog that opened now you can enter a name for this YubiKey and insert the Client ID you noted before as well as the Secret key into the fields provided. Finally, enter your current account password and, after selecting the Touch Yubikey field, touch your YubiKey button. Congratulations! You can now log in to the mailcow UI using your YubiKey! WebAuthn (U2F, replacement) \u00b6 Warning Since February 2022 Google Chrome has discarded support for U2F and standardized the use of WebAuthn. The WebAuthn (U2F removal) is part of mailcow since 21th January 2022, so if you want to use the Key past February 2022 please consider a update with the update.sh To use WebAuthn, the browser must support this standard. The following desktop browsers support this authentication type: Edge (>=18) Firefox (>=60) Chrome (>=67) Safari (>=13) Opera (>=54) The following mobile browsers support this authentication type: Safari on iOS (>=14.5) Android Browser (>=97) Opera Mobile (>=64) Chrome for Android (>=97) Sources: caniuse.com , blog.mozilla.org WebAuthn works without an internet connection. What will happen to my registered Fido Security Key after the Update from U2F to WebAuthn? \u00b6 Warning With this new U2F replacement (WebAuthn) you have to re-register your Fido Security Key, thankfully WebAuthn is backwards compatible and supports the U2F protocol. Ideally, the next time you log in (with the key), you should get a text box saying that your Fido Security Key has been removed due to the update to WebAuthn and deleted as a 2-factor authenticator. But don't worry! You can simply re-register your existing key and use it as usual, you probably won't even notice a difference, except that your browser won't show the U2F deactivation message anymore. Disable unofficial supported Fido Security Keys \u00b6 With WebAuthn there is the possibility to use only official Fido Security Keys (from the big brands like: Yubico, Apple, Nitro, Google, Huawei, Microsoft, etc.). This is primarily for security purposes, as it allows administrators to ensure that only official hardware can be used in their environment. To enable this feature, change the value WEBAUTHN_ONLY_TRUSTED_VENDORS in mailcow.conf from n to y and restart the affected containers with docker-compose up -d . The mailcow will now use the Vendor Certificates located in your mailcow directory under data/web/inc/lib/WebAuthn/rootCertificates . Example: \u00b6 If you want to limit the official Vendor devices to Apple only you only need the Apple Vendor Certificate inside the data/web/inc/lib/WebAuthn/rootCertificates . After you deleted all other certs you now only can activate WebAuthn 2FA with Apple devices. That\u00b4s for every vendor the same, so choose what you like (if you want to). Use own certificates for WebAuthn \u00b6 If you have a valid certificate from the vendor of your key you can also add it to your mailcow! Just copy the certificate into the data/web/inc/lib/WebAuthn/rootCertificates folder and restart your mailcow. Now you should be able to register this device as well, even though the verification for the vendor certificates is enabled, since you just added the certificate manually. Is it dangerous to keep the Vendor Check disabled? \u00b6 No, it isn\u00b4t! These vendor certificates are only used to verify original hardware, not to secure the registration process. As you can read in these articles, the deactivation is not software security related: - https://developers.yubico.com/U2F/Attestation_and_Metadata/ - https://medium.com/webauthnworks/webauthn-fido2-demystifying-attestation-and-mds-efc3b3cb3651 - https://medium.com/webauthnworks/sorting-fido-ctap-webauthn-terminology-7d32067c0b01 In the end, however, it is of course your decision to leave this check disabled or enabled. TOTP \u00b6 The best known TFA method mostly used with a smartphone. To setup the TOTP method login to the Admin UI and select Time-based OTP (TOTP) from the list. Now a modal will open in which you have to type in a name for your 2FA \"device\" (example: John Deer\u00b4s Smartphone) and the password of the affected Admin account (you are currently logged in with). You have two seperate methods to register TOTP to your account: 1. Scan the QR-Code with your Authenticator App on a Smartphone or Tablet. 2. Use the TOTP Code (under the QR Code) in your TOTP Program or App (if you can\u00b4t scan a QR Code). After you have registered the QR or TOTP code in the TOTP app/program of your choice you only need to enter the now generated TOTP token (in the app/program) as confirmation in the mailcow UI to finally activate the TOTP 2FA, otherwise it will not be activated even though the TOTP token is already generated in your app/program.","title":"Two-Factor Authentication"},{"location":"u_e-mailcow_ui-tfa/#yubi-otp","text":"The Yubi API ID and Key will be checked against the Yubico Cloud API.

Ideally, the next time you log in (with the key), you should get a text box saying that your Fido Security Key has been removed due to the update to WebAuthn and deleted as a 2-factor authenticator.

You can simply re-register your existing key and use it as usual, you probably won't even notice a difference, except that your browser won't show the U2F deactivation message anymore.","title":"What will happen to my registered Fido Security Key after the Update from U2F to WebAuthn?"},{"location":"u_e-mailcow_ui-tfa/#disable-unofficial-supported-fido-security-keys","text":"With WebAuthn there is the possibility to use only official Fido Security Keys (from the big brands like: Yubico, Apple, Nitro, Google, Huawei, Microsoft, etc.).

Learn Spam & Ham \u00b6 Rspamd learns mail as spam or ham when you move a message in or out of the junk folder to any mailbox besides trash. This is achieved by using the Sieve plugin \"sieve_imapsieve\" and parser scripts. Rspamd also auto-learns mail when a high or low score is detected (see https://rspamd.com/doc/configuration/statistic.html#autolearning ). We configured the plugin to keep a sane ratio between spam and ham learns. The bayes statistics are written to Redis as keys BAYES_HAM and BAYES_SPAM . Besides bayes, a local fuzzy storage is used to learn recurring patterns in text or images that indicate ham or spam. You can also use Rspamd's web UI to learn ham and / or spam or to adjust certain settings of Rspamd. Learn Spam or Ham from existing directory \u00b6 You can use a one-liner to learn mail in plain-text (uncompressed) format: # Ham for file in /my/folder/cur/* ; do docker exec -i $( docker-compose ps -q rspamd-mailcow ) rspamc learn_ham < $file ; done # Spam for file in /my/folder/.Junk/cur/* ; do docker exec -i $( docker-compose ps -q rspamd-mailcow ) rspamc learn_spam < $file ; done Consider attaching a local folder as new volume to rspamd-mailcow in docker-compose.yml and learn given files inside the container. This can be used as workaround to parse compressed data with zcat. Example: for file in /data/old_mail/.Junk/cur/* ; do rspamc learn_spam < zcat $file ; done Reset learned data (Bayes, Neural) \u00b6 You need to delete keys in Redis to reset learned data, so create a copy of your Redis database now: Backup database # It is better to stop Redis before you copy the file. cp /var/lib/docker/volumes/mailcowdockerized_redis-vol-1/_data/dump.rdb /root/ Reset Bayes data docker-compose exec redis-mailcow sh -c 'redis-cli --scan --pattern BAYES_* | xargs redis-cli del' docker-compose exec redis-mailcow sh -c 'redis-cli --scan --pattern RS* | xargs redis-cli del' Reset Neural data docker-compose exec redis-mailcow sh -c 'redis-cli --scan --pattern rn_* | xargs redis-cli del' Reset Fuzzy data # We need to enter the redis-cli first: docker-compose exec redis-mailcow redis-cli # In redis-cli: 127 .0.0.1:6379> EVAL \"for i, name in ipairs(redis.call('KEYS', ARGV[1])) do redis.call('DEL', name); end\" 0 fuzzy* Info If redis-cli complains about...

CLI tools \u00b6 docker-compose exec rspamd-mailcow rspamc --help docker-compose exec rspamd-mailcow rspamadm --help Disable Greylisting \u00b6 Only messages with a higher score will be considered to be greylisted (soft rejected).

While the above works for rejected mails with a high spam score, prefilter reject actions will ignore this setting. For these maps, the multimap module in Rspamd needs to be adjusted: Find prefilet reject symbol for which you want change message, to do it run: grep -R \"SYMBOL_YOU_WANT_TO_ADJUST\" /opt/mailcow-dockerized/data/conf/rspamd/ Add your custom message as new line: GLOBAL_RCPT_BL { type = \"rcpt\"; map = \"${LOCAL_CONFDIR}/custom/global_rcpt_blacklist.map\"; regexp = true; prefilter = true; action = \"reject\"; message = \"Sending mail to this recipient is prohibited by postmaster@your.domain\"; } Save the file and restart Rspamd: docker-compose restart rspamd-mailcow . Whitelist specific ClamAV signatures \u00b6 You may find that legitimate (clean) mail is being blocked by ClamAV (Rspamd will flag the mail with VIRUS_FOUND ).

Learn how to install Docker and Docker Compose . Quick installation for most operation systems: Docker curl -sSL https://get.docker.com/ | CHANNEL=stable sh # After the installation process is finished, you may need to enable the service and make sure it is started (e.g. CentOS 7) systemctl enable --now docker Docker-Compose Warning mailcow requires the latest version of docker-compose v1. It is highly recommended to use the commands below to install docker-compose . Package managers (e.g. apt , yum ) likely won't give you the correct version. Note: This command downloads docker-compose from the official Docker Github repository and is a safe method. The snippet will determine the latest supported version by mailcow. In almost all cases this is the latest version available (exceptions are broken releases or major changes not yet supported by mailcow). curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose Please use the latest Docker engine available and do not use the engine that ships with your distros repository. 1.1. On SELinux enabled systems, e.g. CentOS 7: Check if \"container-selinux\" package is present on your system: rpm -qa | grep container-selinux If the above command returns an empty or no output, you should install it via your package manager. Check if docker has SELinux support enabled: docker info | grep selinux If the above command returns an empty or no output, create or edit /etc/docker/daemon.json and add \"selinux-enabled\": true . Example file content: { \"selinux-enabled\": true } Restart the docker daemon and verify SELinux is now enabled. This step is required to make sure mailcows volumes are properly labeled as declared in the compose file. If you are interested in how this works, you can check out the readme of https://github.com/containers/container-selinux which links to a lot of useful information on that topic. 2. Clone the master branch of the repository, make sure your umask equals 0022. Please clone the repository as root user and also control the stack as root. We will modify attributes - if necessary - while boostrapping the containers automatically and make sure everything is secured. The update.sh script must therefore also be run as root. It might be necessary to change ownership and other attributes of files you will otherwise not have access to. We drop permissions for every exposed application and will not run an exposed service as root! Controlling the Docker daemon as non-root user does not give you additional security. The unprivileged user will spawn the containers as root likewise. The behaviour of the stack is identical. $ su # umask 0022 # <- Verify it is 0022 # cd /opt # git clone https://github.com/mailcow/mailcow-dockerized # cd mailcow-dockerized 3. Generate a configuration file. Use a FQDN ( host.domain.tld ) as hostname when asked. ./generate_config.sh 4. Change configuration if you want or need to. nano mailcow.conf If you plan to use a reverse proxy, you can, for example, bind HTTPS to 127.0.0.1 on port 8443 and HTTP to 127.0.0.1 on port 8080. You may need to stop an existing pre-installed MTA which blocks port 25/tcp. See this chapter to learn how to reconfigure Postfix to run besides mailcow after a successful installation. Some updates modify mailcow.conf and add new parameters. It is hard to keep track of them in the documentation. Please check their description and, if unsure, ask at the known channels for advise. 4.1. Users with a MTU not equal to 1500 (e.g. OpenStack): Whenever you run into trouble and strange phenomena, please check your MTU. Edit docker-compose.yml and change the network settings according to your MTU. Add the new driver_opts parameter like this: networks: mailcow-network: ... driver_opts: com.docker.network.driver.mtu: 1450 ... 4.2. Users without an IPv6 enabled network on their host system: Enable IPv6. Finally. If you do not have an IPv6 enabled network on your host and you don't care for a better internet (thehe), it is recommended to disable IPv6 for the mailcow network to prevent unforeseen issues. 5. Pull the images and run the compose file. The parameter -d will start mailcow: dockerized detached: docker-compose pull docker-compose up -d Done! You can now access https://${MAILCOW_HOSTNAME} with the default credentials admin + password moohoo . Info If you are not using mailcow behind a reverse proxy, you should redirect all HTTP requests to HTTPS . The database will be initialized right after a connection to MySQL can be established. Your data will persist in multiple Docker volumes, that are not deleted when you recreate or delete containers. Run docker volume ls to see a list of all volumes. You can safely run docker-compose down without removing persistent data.","title":"Installation"},{"location":"i_u_m/i_u_m_migration/","text":"Warning This guide assumes you intend to migrate an existing mailcow server (source) over to a brand new, empty server (target). It takes no care about preserving any existing data on your target server and will erase anything within /var/lib/docker/volumes and thus any Docker volumes you may have already set up. Tip Alternatively, you can use the ./helper-scripts/backup_and_restore.sh script to create a full backup on the source machine, then install mailcow on the target machine as usual, copy over your mailcow.conf and use the same script to restore your backup to the target machine. 1. Install Docker and Docker Compose on your new server. Quick installation for most operation systems: Docker curl -sSL https://get.docker.com/ | CHANNEL=stable sh # After the installation process is finished, you may need to enable the service and make sure it is started (e.g. CentOS 7) systemctl enable docker.service docker-compose curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose Please use the latest Docker engine available and do not use the engine that ships with your distros repository. 2. Stop Docker and assure Docker has stopped: systemctl stop docker.service systemctl status docker.service 3. Run the following commands on the source machine (take care of adding the trailing slashes in the first path parameter as shown below!) - WARNING: This command will erase anything that may already exist under /var/lib/docker/volumes on the target machine : rsync -aHhP --numeric-ids --delete /opt/mailcow-dockerized/ root@target-machine.example.com:/opt/mailcow-dockerized rsync -aHhP --numeric-ids --delete /var/lib/docker/volumes/ root@target-machine.example.com:/var/lib/docker/volumes 4. Shut down mailcow and stop Docker on the source machine. cd /opt/mailcow-dockerized docker-compose down systemctl stop docker.service 5. Repeat step 3 with the same commands. This will be much quicker than the first time. 6. Switch over to the target machine and start Docker. systemctl start docker.service 7. Now pull the mailcow Docker images on the target machine. cd /opt/mailcow-dockerized docker-compose pull 8. Start the whole mailcow stack and everything should be done! docker-compose up -d 9.

It's a powerful and fast filter system. For a more in-depth documentation on Rspamd please visit its own documentation . Learn Spam & Ham \u00b6 Rspamd learns mail as spam or ham when you move a message in or out of the junk folder to any mailbox besides trash. This is achieved by using the Sieve plugin \"sieve_imapsieve\" and parser scripts. Rspamd also auto-learns mail when a high or low score is detected (see https://rspamd.com/doc/configuration/statistic.html#autolearning ). We configured the plugin to keep a sane ratio between spam and ham learns. The bayes statistics are written to Redis as keys BAYES_HAM and BAYES_SPAM . Besides bayes, a local fuzzy storage is used to learn recurring patterns in text or images that indicate ham or spam. You can also use Rspamd's web UI to learn ham and / or spam or to adjust certain settings of Rspamd. Learn Spam or Ham from existing directory \u00b6 You can use a one-liner to learn mail in plain-text (uncompressed) format: # Ham for file in /my/folder/cur/* ; do docker exec -i $( docker-compose ps -q rspamd-mailcow ) rspamc learn_ham < $file ; done # Spam for file in /my/folder/.Junk/cur/* ; do docker exec -i $( docker-compose ps -q rspamd-mailcow ) rspamc learn_spam < $file ; done Consider attaching a local folder as new volume to rspamd-mailcow in docker-compose.yml and learn given files inside the container. This can be used as workaround to parse compressed data with zcat. Example: for file in /data/old_mail/.Junk/cur/* ; do rspamc learn_spam < zcat $file ; done Reset learned data (Bayes, Neural) \u00b6 You need to delete keys in Redis to reset learned data, so create a copy of your Redis database now: Backup database # It is better to stop Redis before you copy the file. cp /var/lib/docker/volumes/mailcowdockerized_redis-vol-1/_data/dump.rdb /root/ Reset Bayes data docker-compose exec redis-mailcow sh -c 'redis-cli --scan --pattern BAYES_* | xargs redis-cli del' docker-compose exec redis-mailcow sh -c 'redis-cli --scan --pattern RS* | xargs redis-cli del' Reset Neural data docker-compose exec redis-mailcow sh -c 'redis-cli --scan --pattern rn_* | xargs redis-cli del' Reset Fuzzy data # We need to enter the redis-cli first: docker-compose exec redis-mailcow redis-cli # In redis-cli: 127 .0.0.1:6379> EVAL \"for i, name in ipairs(redis.call('KEYS', ARGV[1])) do redis.call('DEL', name); end\" 0 fuzzy* Info If redis-cli complains about...

CLI tools \u00b6 docker-compose exec rspamd-mailcow rspamc --help docker-compose exec rspamd-mailcow rspamadm --help Disable Greylisting \u00b6 Only messages with a higher score will be considered to be greylisted (soft rejected). It is bad practice to disable greylisting. You can disable greylisting server-wide by editing: {mailcow-dir}/data/conf/rspamd/local.d/greylist.conf Add the line: enabled = false ; Save the file and restart \"rspamd-mailcow\": docker-compose restart rspamd-mailcow Spam filter thresholds (global) \u00b6 Each user is able to change their spam rating individually .

To reset custom defined thresholds, run: source mailcow.conf docker-compose exec mysql-mailcow mysql -umailcow -p$DBPASS mailcow -e \"delete from filterconf where option = 'highspamlevel' or option = 'lowspamlevel';\" # or: # docker-compose exec mysql-mailcow mysql -umailcow -p$DBPASS mailcow -e \"delete from filterconf where option = 'highspamlevel' or option = 'lowspamlevel' and object = 'only-this-mailbox@example.org';\" Custom reject messages \u00b6 The default spam reject message can be changed by adding a new file data/conf/rspamd/override.d/worker-proxy.custom.inc with the following content: reject_message = \"My custom reject message\"; Save the file and restart Rspamd: docker-compose restart rspamd-mailcow . While the above works for rejected mails with a high spam score, prefilter reject actions will ignore this setting. For these maps, the multimap module in Rspamd needs to be adjusted: Find prefilet reject symbol for which you want change message, to do it run: grep -R \"SYMBOL_YOU_WANT_TO_ADJUST\" /opt/mailcow-dockerized/data/conf/rspamd/ Add your custom message as new line: GLOBAL_RCPT_BL { type = \"rcpt\"; map = \"${LOCAL_CONFDIR}/custom/global_rcpt_blacklist.map\"; regexp = true; prefilter = true; action = \"reject\"; message = \"Sending mail to this recipient is prohibited by postmaster@your.domain\"; } Save the file and restart Rspamd: docker-compose restart rspamd-mailcow . Whitelist specific ClamAV signatures \u00b6 You may find that legitimate (clean) mail is being blocked by ClamAV (Rspamd will flag the mail with VIRUS_FOUND ). For instance, interactive PDF form attachments are blocked by default because the embedded Javascript code may be used for nefarious purposes. Confirm by looking at the clamd logs, e.g.: docker-compose logs clamd-mailcow | grep \"FOUND\" This line confirms that such was identified: clamd-mailcow_1 | Sat Sep 28 07:43:24 2019 -> instream(local): PUA.Pdf.Trojan.EmbeddedJavaScript-1(e887d2ac324ce90750768b86b63d0749:363325) FOUND To whitelist this particular signature (and enable sending this type of file attached), add it to the ClamAV signature whitelist file: echo 'PUA.Pdf.Trojan.EmbeddedJavaScript-1' >> data/conf/clamav/whitelist.ign2 Then restart the clamd-mailcow service container in the mailcow UI or using docker-compose: docker-compose restart clamd-mailcow Cleanup cached ClamAV results in Redis: # docker-compose exec redis-mailcow /bin/sh /data # redis-cli KEYS rs_cl* | xargs redis-cli DEL /data # exit Discard instead of reject \u00b6 If you want to silently drop a message, create or edit the file data/conf/rspamd/override.d/worker-proxy.custom.inc and add the following content: discard_on_reject = true; Restart Rspamd: docker-compose restart rspamd-mailcow Wipe all ratelimit keys \u00b6 If you don't want to use the UI and instead wipe all keys in the Redis database, you can use redis-cli for that task: docker-compose exec redis-mailcow sh # Unlink (available in Redis >=4.) will delete in the backgronud redis-cli --scan --pattern RL* | xargs redis-cli unlink Restart Rspamd: docker-compose exec redis-mailcow sh Trigger a resend of quarantine notifications \u00b6 Should be used for debugging only! docker-compose exec dovecot-mailcow bash mysql -umailcow -p$DBPASS mailcow -e \"update quarantine set notified = 0;\" redis-cli -h redis DEL Q_LAST_NOTIFIED quarantine_notify.py Increase history retention \u00b6 By default Rspamd keeps 1000 elements in the history.

Both WebAuthn and Yubi OTP work well with the fantastic Yubikey . While Yubi OTP needs an active internet connection and an API ID + key, WebAuthn will work with any Fido Security Key out of the box, but can only be used when mailcow is accessed over HTTPS. WebAuthn and Yubi OTP support multiple keys per user. As the third TFA method mailcow uses TOTP: time-based one-time passwords. Those passwords can be generated with apps like \"Google Authenticator\" after initially scanning a QR code or entering the given secret manually. As administrator you are able to temporary disable a domain administrators TFA login until they successfully logged in. The key used to login will be displayed in green, while other keys remain grey. Information on how to remove 2FA can be found here . Yubi OTP \u00b6 The Yubi API ID and Key will be checked against the Yubico Cloud API. When setting up TFA you will be asked for your personal API account for this key. The API ID, API key and the first 12 characters (your YubiKeys ID in modhex) are stored in the MySQL table as secret. Example setup \u00b6 First of all, the YubiKey must be configured for use as an OTP Generator. To do this, download the YubiKey Manager from the Yubico website: here In the following you configure the YubiKey for OTP. Via the menu item Applications -> OTP and a click on the Configure button. In the following menu select Credential Type -> Yubico OTP and click on Next . Set a checkmark in the Use serial checkbox, generate a Private ID and a Secret key via the buttons. So that the YubiKey can be validated later, the checkmark in the Upload checkbox must also be set and then click on Finish . Now a new browser window will open in which you have to enter an OTP of your YubiKey at the bottom of the form (click on the field and then tap on your YubiKey). Confirm the captcha and upload the information to the Yubico server by clicking 'Upload'. The processing of the data will take a moment. After the generation was successful, you will be shown a Client ID and a Secret key , make a note of this information in a safe place. Now you can select Yubico OTP authentication from the dropdown menu in the mailcow UI on the start page under Access -> Two-factor authentication . In the dialog that opened now you can enter a name for this YubiKey and insert the Client ID you noted before as well as the Secret key into the fields provided. Finally, enter your current account password and, after selecting the Touch Yubikey field, touch your YubiKey button. Congratulations! You can now log in to the mailcow UI using your YubiKey! WebAuthn (U2F, replacement) \u00b6 Warning Since February 2022 Google Chrome has discarded support for U2F and standardized the use of WebAuthn. The WebAuthn (U2F removal) is part of mailcow since 21th January 2022, so if you want to use the Key past February 2022 please consider a update with the update.sh To use WebAuthn, the browser must support this standard. The following desktop browsers support this authentication type: Edge (>=18) Firefox (>=60) Chrome (>=67) Safari (>=13) Opera (>=54) The following mobile browsers support this authentication type: Safari on iOS (>=14.5) Android Browser (>=97) Opera Mobile (>=64) Chrome for Android (>=97) Sources: caniuse.com , blog.mozilla.org WebAuthn works without an internet connection. What will happen to my registered Fido Security Key after the Update from U2F to WebAuthn? \u00b6 Warning With this new U2F replacement (WebAuthn) you have to re-register your Fido Security Key, thankfully WebAuthn is backwards compatible and supports the U2F protocol. Ideally, the next time you log in (with the key), you should get a text box saying that your Fido Security Key has been removed due to the update to WebAuthn and deleted as a 2-factor authenticator. But don't worry! You can simply re-register your existing key and use it as usual, you probably won't even notice a difference, except that your browser won't show the U2F deactivation message anymore. Disable unofficial supported Fido Security Keys \u00b6 With WebAuthn there is the possibility to use only official Fido Security Keys (from the big brands like: Yubico, Apple, Nitro, Google, Huawei, Microsoft, etc.). This is primarily for security purposes, as it allows administrators to ensure that only official hardware can be used in their environment. To enable this feature, change the value WEBAUTHN_ONLY_TRUSTED_VENDORS in mailcow.conf from n to y and restart the affected containers with docker-compose up -d . The mailcow will now use the Vendor Certificates located in your mailcow directory under data/web/inc/lib/WebAuthn/rootCertificates . Example: \u00b6 If you want to limit the official Vendor devices to Apple only you only need the Apple Vendor Certificate inside the data/web/inc/lib/WebAuthn/rootCertificates . After you deleted all other certs you now only can activate WebAuthn 2FA with Apple devices. That\u00b4s for every vendor the same, so choose what you like (if you want to). Use own certificates for WebAuthn \u00b6 If you have a valid certificate from the vendor of your key you can also add it to your mailcow! Just copy the certificate into the data/web/inc/lib/WebAuthn/rootCertificates folder and restart your mailcow. Now you should be able to register this device as well, even though the verification for the vendor certificates is enabled, since you just added the certificate manually. Is it dangerous to keep the Vendor Check disabled? \u00b6 No, it isn\u00b4t! These vendor certificates are only used to verify original hardware, not to secure the registration process. As you can read in these articles, the deactivation is not software security related: - https://developers.yubico.com/U2F/Attestation_and_Metadata/ - https://medium.com/webauthnworks/webauthn-fido2-demystifying-attestation-and-mds-efc3b3cb3651 - https://medium.com/webauthnworks/sorting-fido-ctap-webauthn-terminology-7d32067c0b01 In the end, however, it is of course your decision to leave this check disabled or enabled. TOTP \u00b6 The best known TFA method mostly used with a smartphone. To setup the TOTP method login to the Admin UI and select Time-based OTP (TOTP) from the list. Now a modal will open in which you have to type in a name for your 2FA \"device\" (example: John Deer\u00b4s Smartphone) and the password of the affected Admin account (you are currently logged in with). You have two seperate methods to register TOTP to your account: 1. Scan the QR-Code with your Authenticator App on a Smartphone or Tablet. 2. Use the TOTP Code (under the QR Code) in your TOTP Program or App (if you can\u00b4t scan a QR Code). After you have registered the QR or TOTP code in the TOTP app/program of your choice you only need to enter the now generated TOTP token (in the app/program) as confirmation in the mailcow UI to finally activate the TOTP 2FA, otherwise it will not be activated even though the TOTP token is already generated in your app/program.","title":"Two-Factor Authentication"},{"location":"manual-guides/mailcow-UI/u_e-mailcow_ui-tfa/#yubi-otp","text":"The Yubi API ID and Key will be checked against the Yubico Cloud API.

Important information, please read them carefully! Info If you plan to use a reverse proxy and want to use another server name that is not MAILCOW_HOSTNAME, you need to read Adding additional server names for mailcow UI at the bottom of this page. Warning Make sure you run generate_config.sh before you enable any site configuration examples below. The script generate_config.sh copies snake-oil certificates to the correct location, so the services will not fail to start due to missing files. Warning If you enable TLS SNI ( ENABLE_TLS_SNI in mailcow.conf), the certificate paths in your reverse proxy must match the correct paths in data/assets/ssl/{hostname}. The certificates will be split into data/assets/ssl/{hostname1,hostname2,etc} and therefore will not work when you copy the examples from below pointing to data/assets/ssl/cert.pem etc. Info Using the site configs below will forward ACME requests to mailcow and let it handle certificates itself. The downside of using mailcow as ACME client behind a reverse proxy is, that you will need to reload your webserver after acme-mailcow changed/renewed/created the certificate. You can either reload your webserver daily or write a script to watch the file for changes. On many servers logrotate will reload the webserver daily anyway. If you want to use a local certbot installation, you will need to change the SSL certificate parameters accordingly. Make sure you run a post-hook script when you decide to use external ACME clients.

Validation errors and how to skip validation \u00b6 You can skip the IP verification by setting SKIP_IP_CHECK=y in mailcow.conf (no quotes). Be warned that a misconfiguration will get you ratelimited by Let's Encrypt! This is primarily useful for multi-IP setups where the IP check would return the incorrect source IP address. Due to using dynamic IPs for acme-mailcow, source NAT is not consistent over restarts. If you encounter problems with \"HTTP validation\", but your IP address confirmation succeeds, you are most likely using firewalld, ufw or any other firewall, that disallows connections from br-mailcow to your external interface. Both firewalld and ufw disallow this by default. It is often not enough to just stop these firewall services. You'd need to stop mailcow ( docker-compose down ), stop the firewall service, flush the chains and restart Docker. You can also skip this validation method by setting SKIP_HTTP_VERIFICATION=y in \"mailcow.conf\". Be warned that this is discouraged. In most cases, the HTTP verification is skipped to workaround unknown NAT reflection issues, which are not resolved by ignoring this specific network misconfiguration. If you encounter problems generating TLSA records in the DNS overview within mailcow, you are most likely having issues with NAT reflection you should fix. If you changed a SKIP_* parameter, run docker-compose up -d to apply your changes. Disable Let's Encrypt \u00b6 Disable Let's Encrypt completely \u00b6 Set SKIP_LETS_ENCRYPT=y in \"mailcow.conf\" and recreate \"acme-mailcow\" by running docker-compose up -d . Skip all names but ${MAILCOW_HOSTNAME} \u00b6 Add ONLY_MAILCOW_HOSTNAME=y to \"mailcow.conf\" and recreate \"acme-mailcow\" by running docker-compose up -d . The Let's Encrypt subjectAltName limit of 100 domains \u00b6 Let's Encrypt currently has a limit of 100 Domain Names per Certificate . By default, \"acme-mailcow\" will create a single SAN certificate for all validated domains (see the first section and Additional domain names ). This provides best compatibility but means the Let's Encrypt limit exceeds if you add too many domains to a single mailcow installation. To solve this, you can configure ENABLE_SSL_SNI to generate: A main server certificate with MAILCOW_HOSTNAME and all fully qualified domain names in the ADDITIONAL_SAN config One additional certificate for each domain found in the database with autodiscover. , autoconfig. and any other ADDITIONAL_SAN configured in this format (subdomain.*). Limitations: A certificate name ADDITIONAL_SAN=test.example.com will be added as SAN to the main certificate. A separate certificate/key pair will not be generated for this format. Postfix, Dovecot and Nginx will then serve these certificates with SNI. Set ENABLE_SSL_SNI=y in \"mailcow.conf\" and recreate \"acme-mailcow\" by running docker-compose up -d . Warning Not all clients support SNI, see Dovecot documentation or Wikipedia . You should make sure these clients use the MAILCOW_HOSTNAME for secure connections if you enable this feature. Here is an example: MAILCOW_HOSTNAME=server.email.tld ADDITIONAL_SAN=webmail.email.tld,mail.* Mailcow email domains: \"domain1.tld\" and \"domain2.tld\" The following certificates will be generated: server.email.tld, webmail.email.tld -> this is the default certificate, all clients can connect with these domains mail.domain1.tld, autoconfig.domain1.tld, autodiscover.domain1.tld -> individual certificate for domain1.tld, cannot be used by clients without SNI support mail.domain2.tld, autoconfig.domain2.tld, autodiscover.domain2.tld -> individual certificate for domain2.tld, cannot be used by clients without SNI support How to use your own certificate \u00b6 Make sure you disable mailcows internal LE client (see above). To use your own certificates, just save the combined certificate (containing the certificate and intermediate CA/CA if any) to data/assets/ssl/cert.pem and the corresponding key to data/assets/ssl/key.pem . IMPORTANT: Do not use symbolic links! Make sure you copy the certificates and do not link them to data/assets/ssl . Restart affected services afterwards: docker restart $(docker ps -qaf name=postfix-mailcow) docker restart $(docker ps -qaf name=nginx-mailcow) docker restart $(docker ps -qaf name=dovecot-mailcow) See Post-hook script for non-mailcow ACME clients for a full example script.

Both firewalld and ufw disallow this by default. It is often not enough to just stop these firewall services. You'd need to stop mailcow ( docker-compose down ), stop the firewall service, flush the chains and restart Docker. You can also skip this validation method by setting SKIP_HTTP_VERIFICATION=y in \"mailcow.conf\". Be warned that this is discouraged.

Info mailcow: dockerized requires some ports to be open for incoming connections, so make sure that your firewall is not blocking these. Make sure that no other application is interfering with mailcow's configuration, such as another mail service A correct DNS setup is crucial to every good mailserver setup, so please make sure you got at least the basics covered before you begin! Make sure that your system has a correct date and time setup . This is crucial for various components like two factor TOTP authentication. Minimum System Resources \u00b6 OpenVZ, Virtuozzo and LXC are not supported . Please make sure that your system has at least the following resources: Resource mailcow: dockerized CPU 1 GHz RAM Minimum 6 GiB + 1 GiB swap (default config) Disk 20 GiB (without emails) System Type x86_64 We recommend using any distribution listed as supported by Docker CE (check https://docs.docker.com/install/ ). We test on CentOS 7, Debian 10/11 and Ubuntu 18.04/20.04. ClamAV and Solr can be greedy with RAM. You may disable them in mailcow.conf by settings SKIP_CLAMD=y and SKIP_SOLR=y . Info : We are aware that a pure MTA can run on 128 MiB RAM. mailcow is a full-grown and ready-to-use groupware with many extras making life easier. mailcow comes with a webserver, webmailer, ActiveSync (MS), antivirus, antispam, indexing (Solr), document scanner (Oletools), SQL (MariaDB), Cache (Redis), MDA, MTA, various web services etc. A single SOGo worker can acquire ~350 MiB RAM before it gets purged. The more ActiveSync connections you plan to use, the more RAM you will need. A default configuration spawns 20 workers. Usage examples \u00b6 A company with 15 phones (EAS enabled) and about 50 concurrent IMAP connections should plan 16 GiB RAM. 6 GiB RAM + 1 GiB swap are fine for most private installations while 8 GiB RAM are recommended for ~5 to 10 users. We can help to correctly plan your setup as part of our support. Firewall & Ports \u00b6 Please check if any of mailcow's standard ports are open and not in use by other applications: ss -tlpn | grep -E -w '25|80|110|143|443|465|587|993|995|4190|5222|5269|5443' # or: netstat -tulpn | grep -E -w '25|80|110|143|443|465|587|993|995|4190|5222|5269|5443' Warning There are several problems with running mailcow on a firewalld/ufw enabled system. You should disable it (if possible) and move your ruleset to the DOCKER-USER chain, which is not cleared by a Docker service restart, instead. See this (blog.donnex.net) or this (unrouted.io) guide for information about how to use iptables-persistent with the DOCKER-USER chain.

Due to it's deduplication capabilities you can store a great number of backups without wasting large amounts of disk space. This allows you to run backups in very short intervals to ensure minimal data loss when the need arises to recover data from a backup. This document guides you through the process to enable continuous backups for mailcow with borgmatic. The borgmatic functionality is provided by the borgmatic Docker image by b3vis . Check out the README in that repository to find out about the other options (such as push notifications) that are available. This guide only covers the basics. Setting up borgmatic \u00b6 Create or amend docker-compose.override.yml \u00b6 In the mailcow-dockerized root folder create or edit docker-compose.override.yml and insert the following configuration: version : '2.1' services : borgmatic-mailcow : image : b3vis/borgmatic hostname : mailcow restart : always dns : ${IPV4_NETWORK:-172.22.1}.254 volumes : - vmail-vol-1:/mnt/source/vmail:ro - crypt-vol-1:/mnt/source/crypt:ro - redis-vol-1:/mnt/source/redis:ro,z - rspamd-vol-1:/mnt/source/rspamd:ro,z - postfix-vol-1:/mnt/source/postfix:ro,z - mysql-socket-vol-1:/var/run/mysqld/:z - borg-config-vol-1:/root/.config/borg:Z - borg-cache-vol-1:/root/.cache/borg:Z - ./data/conf/borgmatic/etc:/etc/borgmatic.d:Z - ./data/conf/borgmatic/ssh:/root/.ssh:Z environment : - TZ=${TZ} - BORG_PASSPHRASE=YouBetterPutSomethingRealGoodHere networks : mailcow-network : aliases : - borgmatic volumes : borg-cache-vol-1 : borg-config-vol-1 : Ensure that you change the BORG_PASSPHRASE to a secure passphrase of your choosing. For security reasons we mount the maildir as read-only. If you later want to restore data you will need to remove the ro flag prior to restoring the data. This is described in the section on restoring backups. Create data/conf/borgmatic/etc/config.yaml \u00b6 Next, we need to create the borgmatic configuration. source mailcow.conf cat <<EOF > data/conf/borgmatic/etc/config.yaml location: source_directories: - /mnt/source repositories: - user@rsync.net:mailcow exclude_patterns: - '/mnt/source/postfix/public/' - '/mnt/source/postfix/private/' - '/mnt/source/rspamd/rspamd.sock' retention: keep_hourly: 24 keep_daily: 7 keep_weekly: 4 keep_monthly: 6 hooks: mysql_databases: - name: ${DBNAME} username: ${DBUSER} password: ${DBPASS} options: --default-character-set=utf8mb4 EOF Creating the file in this way ensures the correct MySQL credentials are pulled in from mailcow.conf . This file is a minimal example for using borgmatic with an account user on the cloud storage provider rsync.net for a repository called mailcow (see repositories setting). It will backup both the maildir and MySQL database, which is all you should need to restore your mailcow setup after an incident. The retention settings will keep one archive for each hour of the past 24 hours, one per day of the week, one per week of the month and one per month of the past half year. Check the borgmatic documentation on how to use other types of repositories or configuration options. If you choose to use a local filesystem as a backup destination make sure to mount it into the container. The container defines a volume called /mnt/borg-repository for this purpose. Note If you do not use rsync.net you can most likely drop the remote_path element from your config. Create a crontab \u00b6 Create a new text file in data/conf/borgmatic/etc/crontab.txt with the following content: 14 * * * * PATH=$PATH:/usr/bin /usr/bin/borgmatic --stats -v 0 2>&1 This file expects crontab syntax. The example shown here will trigger the backup to run every hour at 14 minutes past the hour and log some nice stats at the end. Place SSH keys in folder \u00b6 Place the SSH keys you intend to use for remote repository connections in data/conf/borgmatic/ssh . OpenSSH expects the usual id_rsa , id_ed25519 or similar to be in this directory. Ensure the file is chmod 600 and not world readable or OpenSSH will refuse to use the SSH key. Bring up the container \u00b6 For the next step we need the container to be up and running in a configured state. To do that run: docker-compose up -d Initialize the repository \u00b6 By now your borgmatic container is up and running, but the backups will currently fail due to the repository not being initialized. To initialize the repository run: docker-compose exec borgmatic-mailcow borgmatic init --encryption repokey-blake2 You will be asked you to authenticate the SSH host key of your remote repository server. See if it matches and confirm the prompt by entering yes . The repository will be initialized with the passphrase you set in the BORG_PASSPHRASE environment variable earlier. When using any of the repokey encryption methods the encryption key will be stored in the repository itself and not on the client, so there is no further action required in this regard. If you decide to use a keyfile instead of a repokey make sure you export the key and back it up separately. Check the Exporting Keys section for how to retrieve the key. Restart container \u00b6 Now that we finished configuring and initializing the repository restart the container to ensure it is in a defined state: docker-compose restart borgmatic-mailcow Restoring from a backup \u00b6 Restoring a backup assumes you are starting off with a fresh installation of mailcow, and you currently do not have any custom data in your maildir or your mailcow database. Restore maildir \u00b6 Warning Doing this will overwrite files in your maildir! Do not run this unless you actually intend to recover mail files from a backup. If you use SELinux in Enforcing mode If you are using mailcow on a host with SELinux in Enforcing mode you will have to temporarily disable it during extraction of the archive as the mailcow setup labels the vmail volume as private, belonging to the dovecot container exclusively. SELinux will (rightfully) prevent any other container, such as the borgmatic container, from writing to this volume. Before running a restore you must make the vmail volume writeable in docker-compose.override.yml by removing the ro flag from the volume. Then you can use the following command to restore the maildir from a backup: docker-compose exec borgmatic-mailcow borgmatic extract --path mnt/source --archive latest Alternatively you can specify any archive name from the list of archives (see Listing all available archives ) Restore MySQL \u00b6 Warning Running this command will delete and recreate the mailcow database! Do not run this unless you actually intend to recover the mailcow database from a backup. To restore the MySQL database from the latest archive use this command: docker-compose exec borgmatic-mailcow borgmatic restore --archive latest Alternatively you can specify any archive name from the list of archives (see Listing all available archives ) After restoring \u00b6 After restoring you need to restart mailcow. If you disabled SELinux enforcing mode now would be a good time to re-enable it. To restart mailcow use the follwing command: docker-compose down && docker-compose up -d If you use SELinux this will also trigger the re-labeling of all files in your vmail volume. Be patient, as this may take a while if you have lots of files. Useful commands \u00b6 Manual archiving run (with debugging output) \u00b6 docker-compose exec borgmatic-mailcow borgmatic -v 2 Listing all available archives \u00b6 docker-compose exec borgmatic-mailcow borgmatic list Break lock \u00b6 When borg is interrupted during an archiving run it will leave behind a stale lock that needs to be cleared before any new operations can be performed: docker-compose exec borgmatic-mailcow borg break-lock user@rsync.net:mailcow Where user@rsync.net:mailcow is the URI to your repository. Now would be a good time to do a manual archiving run to ensure it can be successfully performed. Exporting keys \u00b6 When using any of the keyfile methods for encryption you MUST take care of backing up the key files yourself. The key files are generated when you initialize the repository. The repokey methods store the key file within the repository, so a manual backup isn't as essential. Note that in either case you also must have the passphrase to decrypt any archives. To fetch the keyfile run: docker-compose exec borgmatic-mailcow borg key export --paper user@rsync.net:mailcow Where user@rsync.net:mailcow is the URI to your repository.","title":"Borgmatic Backup"},{"location":"third_party/third_party-borgmatic/#borgmatic-backup","text":"","title":"Borgmatic Backup"},{"location":"third_party/third_party-borgmatic/#introduction","text":"Borgmatic is a great way to run backups on your Mailcow setup as it securely encrypts your data and is extremely easy to set up.

You can follow the official guide from Microsoft . Warning For the connector that handles mails from your mailcow to Exchange Microsoft offers two ways of authenticating it. The recommended way is to use a tls certificate configured with a subject name that matches an accepted domain in Exchange. Otherwise you need to choose authentication with the static ip address of your mailcow. Validating \u00b6 The easiest way to validate the hybrid setup is by sending a mail from the internet to a mailbox that only exists on the mailcow and vice versa.

Please post issues, questions and improvements in the issue tracker there. Warning mailcow is not responsible for any data loss, hardware damage or broken keyboards. This guide comes without any warranty. Make backups before starting, 'coze: No backup no pity! Introduction \u00b6 This guide aims to install and configure mailcow-dockerized with docker-mailman and to provide some useful scripts. An essential condition is, to preserve mailcow and Mailman in their own installations for independent updates. There are some guides and projects on the internet, but they are not up to date and/or incomplete in documentation or configuration. This guide is based on the work of: mailcow-mailman3-dockerized by Shadowghost mailman-mailcow-integration After finishing this guide, mailcow-dockerized and docker-mailman will run and Apache as a reverse proxy will serve the web frontends. The operating system used is an Ubuntu 20.04 LTS . Installation \u00b6 This guide is based on different steps: DNS setup Install Apache as a reverse proxy Obtain SSL certificates with Let's Encrypt Install mailcow with Mailman integration Install Mailman \ud83c\udfc3 Run DNS setup \u00b6 Most of the configuration is covered by mailcow s DNS setup . After finishing this setup add another subdomain for Mailman , e.g. lists.example.org that points to the same server: # Name Type Value lists IN A 1.2.3.4 lists IN AAAA dead:beef Install Apache as a reverse proxy \u00b6 Install Apache , e.g. with this guide from Digital Ocean : How To Install the Apache Web Server on Ubuntu 20.04 . Activate certain Apache modules (as root or sudo ): a2enmod rewrite proxy proxy_http headers ssl wsgi proxy_uwsgi http2 Maybe you have to install further packages to get these modules. This PPA by Ond\u0159ej Sur\u00fd may help you. vHost configuration \u00b6 Copy the mailcow.conf and the mailman.conf in the Apache conf folder sites-available (e.g. under /etc/apache2/sites-available ). Change in mailcow.conf : - MAILCOW_HOSTNAME to your MAILCOW_HOSTNAME Change in mailman.conf : - MAILMAN_DOMAIN to your Mailman domain (e.g. lists.example.org ) Don't activate the configuration, as the ssl certificates and directories are missing yet. Obtain SSL certificates with Let's Encrypt \u00b6 Check if your DNS config is available over the internet and points to the right IP addresses, e.g. with MXToolBox : https://mxtoolbox.com/SuperTool.aspx?action=a%3aMAILCOW_HOSTNAME https://mxtoolbox.com/SuperTool.aspx?action=aaaa%3aMAILCOW_HOSTNAME https://mxtoolbox.com/SuperTool.aspx?action=a%3aMAILMAN_DOMAIN https://mxtoolbox.com/SuperTool.aspx?action=aaaa%3aMAILMAN_DOMAIN Install certbot (as root or sudo ): apt install certbot Get the desired certificates (as root or sudo ): certbot certonly -d mailcow_HOSTNAME certbot certonly -d MAILMAN_DOMAIN Install mailcow with Mailman integration \u00b6 Install mailcow \u00b6 Follow the mailcow installation . Omit step 5 and do not pull and up with docker-compose ! Configure mailcow \u00b6 This is also Step 4 in the official mailcow installation ( nano mailcow.conf ). So change to your needs and alter the following variables: HTTP_PORT=18080 # don't use 8080 as mailman needs it HTTP_BIND=127.0.0.1 # HTTPS_PORT=18443 # you may use 8443 HTTPS_BIND=127.0.0.1 # SKIP_LETS_ENCRYPT=y # reverse proxy will do the SSL termination SNAT_TO_SOURCE=1.2.3.4 # change this to your IPv4 SNAT6_TO_SOURCE=dead:beef # change this to your global IPv6 Add Mailman integration \u00b6 Create the file /opt/mailcow-dockerized/docker-compose.override.yml (e.g. with nano ) and add the following lines: version: '2.1' services: postfix-mailcow: volumes: - /opt/mailman:/opt/mailman networks: - docker-mailman_mailman networks: docker-mailman_mailman: external: true The additional volume is used by Mailman to generate additional config files for mailcow postfix . The external network is build and used by Mailman . mailcow needs it to deliver incoming list mails to Mailman . Create the file /opt/mailcow-dockerized/data/conf/postfix/extra.cf (e.g. with nano ) and add the following lines: # mailman recipient_delimiter = + unknown_local_recipient_reject_code = 550 owner_request_special = no local_recipient_maps = regexp:/opt/mailman/core/var/data/postfix_lmtp, proxy:unix:passwd.byname, $alias_maps virtual_mailbox_maps = proxy:mysql:/opt/postfix/conf/sql/mysql_virtual_mailbox_maps.cf, regexp:/opt/mailman/core/var/data/postfix_lmtp transport_maps = pcre:/opt/postfix/conf/custom_transport.pcre, pcre:/opt/postfix/conf/local_transport, proxy:mysql:/opt/postfix/conf/sql/mysql_relay_ne.cf, proxy:mysql:/opt/postfix/conf/sql/mysql_transport_maps.cf, regexp:/opt/mailman/core/var/data/postfix_lmtp relay_domains = proxy:mysql:/opt/postfix/conf/sql/mysql_virtual_relay_domain_maps.cf, regexp:/opt/mailman/core/var/data/postfix_domains relay_recipient_maps = proxy:mysql:/opt/postfix/conf/sql/mysql_relay_recipient_maps.cf, regexp:/opt/mailman/core/var/data/postfix_lmtp As we overwrite mailcow postfix configuration here, this step may break your normal mail transports. Check the original configuration files if anything changed. SSL certificates \u00b6 As we proxying mailcow , we need to copy the SSL certificates into the mailcow file structure. This task will do the script renew-ssl.sh for us: Copy the file to /opt/mailcow-dockerized Change mailcow_HOSTNAME to your mailcow hostname Make it executable ( chmod a+x renew-ssl.sh ) Do not run it yet, as we first need Mailman You have to create a cronjob , so that new certificates will be copied. Execute as root or sudo : crontab -e To run the script every day at 5am, add: 0 5 * * * /opt/mailcow-dockerized/renew-ssl.sh Install Mailman \u00b6 Basicly follow the instructions at docker-mailman . As they are a lot, here is in a nuthshell what to do: As root or sudo : cd /opt mkdir -p mailman/core mkdir -p mailman/web git clone https://github.com/maxking/docker-mailman cd docker-mailman Configure Mailman \u00b6 Create a long key for Hyperkitty , e.g. with the linux command cat /dev/urandom | tr -dc a-zA-Z0-9 | head -c30; echo . Save this key for a moment as HYPERKITTY_KEY. Create a long password for the database, e.g. with the linux command cat /dev/urandom | tr -dc a-zA-Z0-9 | head -c30; echo . Save this password for a moment as DBPASS. Create a long key for Django , e.g. with the linux command cat /dev/urandom | tr -dc a-zA-Z0-9 | head -c30; echo . Save this key for a moment as DJANGO_KEY.

You need the admin credentials to log into the web interface ( Pistorius ). For setting the password for the first time use the Forgot password function in the web interface. About other configuration options read Mailman-web and Mailman-core documentation. Configure Mailman core and Mailman web \u00b6 Create the file /opt/mailman/core/mailman-extra.cfg with the following content. mailman@example.org should be pointing to a valid mail box or redirection. [mailman] default_language: de site_owner: mailman@example.org Create the file /opt/mailman/web/settings_local.py with the following content. mailman@example.org should be pointing to a valid mail box or redirection. # locale LANGUAGE_CODE = 'de-de' # disable social authentication SOCIALACCOUNT_PROVIDERS = {} # change it DEFAULT_FROM_EMAIL = 'mailman@example.org' DEBUG = False You can change LANGUAGE_CODE and SOCIALACCOUNT_PROVIDERS to your needs. At the moment SOCIALACCOUNT_PROVIDERS has no effect, see issue #2 . \ud83c\udfc3 Run \u00b6 Run (as root or sudo ) a2ensite mailcow.conf a2ensite mailman.conf systemctl restart apache2 cd /opt/docker-mailman docker-compose pull docker-compose up -d cd /opt/mailcow-dockerized/ docker-compose pull ./renew-ssl.sh Wait a few minutes! The containers have to create there databases and config files. This can last up to 1 minute and more. Remarks \u00b6 New lists aren't recognized by postfix instantly \u00b6 When you create a new list and try to immediately send an e-mail, postfix responses with User doesn't exist , because postfix won't deliver it to Mailman yet. The configuration at /opt/mailman/core/var/data/postfix_lmtp is not instantly updated. If you need the list instantly, restart postifx manually: cd /opt/mailcow-dockerized docker-compose restart postfix-mailcow Update \u00b6 mailcow has it's own update script in /opt/mailcow-dockerized/update.sh , see the docs . For Mailman just fetch the newest version from the github repository . Backup \u00b6 mailcow has an own backup script. Read the docs for further informations. Mailman won't state backup instructions in the README.md. In the gitbucket of pgollor is a script that may be helpful. ToDo \u00b6 install script \u00b6 Write a script like in mailman-mailcow-integration/mailman-install.sh as many of the steps are automatable. Ask for all the configuration variables and create passwords and keys. Do a (semi-)automatic installation.

Disclaimer : This is not officially maintained nor supported by the mailcow project nor its contributors. No warranty or support is being provided, however you're free to open issues on GitHub for filing a bug or provide further ideas. GitHub repo can be found here . Info Support for domain wildcards were implemented in Piler 1.3.10 which was released on 03.01.2021. Prior versions basically do work, but after logging in you won't see emails sent from or to the domain alias. (e.g. when @example.com is an alias for admin@example.com ) The problem to solve \u00b6 mailpiler offers the authentication based on IMAP, for example: $config['ENABLE_IMAP_AUTH'] = 1; $config['IMAP_HOST'] = 'mail.example.com'; $config['IMAP_PORT'] = 993; $config['IMAP_SSL'] = true; So when you log in using patrik@example.com , you will only see delivered emails sent from or to this specific email address. When additional aliases are defined in mailcow, like team@example.com , you won't see emails sent to or from this email address even the fact you're a recipient of mails sent to this alias address. By hooking into the authentication process of mailpiler, we are able to get required data via the mailcow API during login. This fires API requests to the mailcow API (requiring read-only API access) to read out the aliases your email address participates and also the \"Name\" of the mailbox specified to display it on the top-right of mailpiler after login. Permitted email addresses can be seen in the mailpiler settings top-right after logging in. Info This is only pulled once during the authentication process. The authorized aliases and the realname are valid for the whole duration of the user session as mailpiler sets them in the session data. If user is removed from specific alias, this will only take effect after next login. The solution \u00b6 Note: File paths might vary depending on your setup.

Es wird dringend empfohlen, die untenstehenden Befehle zu verwenden, um docker-compose zu installieren. Paket-Manager (z.B. apt , yum ) werden wahrscheinlich nicht die richtige Version liefern. Hinweis: Dieser Befehl l\u00e4dt docker-compose aus dem offiziellen Docker-Github-Repository herunter und ist eine sichere Methode. Das Snippet ermittelt die neueste unterst\u00fctzte Version von mailcow. In fast allen F\u00e4llen ist dies die letzte verf\u00fcgbare Version (Ausnahmen sind kaputte Versionen oder gr\u00f6\u00dfere \u00c4nderungen, die noch nicht von mailcow unterst\u00fctzt werden). curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose Bitte verwenden Sie die neueste verf\u00fcgbare Docker-Engine und nicht die Engine, die mit Ihrem Distros-Repository ausgeliefert wird. 1.1.1. Auf SELinux-aktivierten Systemen, z.B. CentOS 7: Pr\u00fcfen Sie, ob das Paket \"container-selinux\" auf Ihrem System vorhanden ist: rpm -qa | grep container-selinux Wenn der obige Befehl eine leere oder keine Ausgabe liefert, sollten Sie es \u00fcber Ihren Paketmanager installieren. Pr\u00fcfen Sie, ob Docker SELinux-Unterst\u00fctzung aktiviert hat: docker info | grep selinux Wenn der obige Befehl eine leere oder keine Ausgabe liefert, erstellen oder bearbeiten Sie /etc/docker/daemon.json und f\u00fcgen Sie \"selinux-enabled\": true hinzu. Beispielhafter Inhalt der Datei: { \"selinux-enabled\": true } Starten Sie den Docker-Daemon neu und \u00fcberpr\u00fcfen Sie, ob SELinux nun aktiviert ist. Dieser Schritt ist erforderlich, um sicherzustellen, dass die Mailcows-Volumes richtig gekennzeichnet sind, wie in der Compose-Datei angegeben. Wenn Sie daran interessiert sind, wie das funktioniert, k\u00f6nnen Sie sich die Readme-Datei von https://github.com/containers/container-selinux ansehen, die auf viele n\u00fctzliche Informationen zu diesem Thema verweist. 2. Klonen Sie den Master-Zweig des Repositorys und stellen Sie sicher, dass Ihre umask gleich 0022 ist. Bitte klonen Sie das Repository als root-Benutzer und kontrollieren Sie auch den Stack als root. Wir werden die Attribute - wenn n\u00f6tig - \u00e4ndern, w\u00e4hrend wir die Container automatisch boosten und sicherstellen, dass alles gesichert ist. Das update.sh-Skript muss daher ebenfalls als root ausgef\u00fchrt werden. Es kann notwendig sein, den Besitz und andere Attribute von Dateien zu \u00e4ndern, auf die Sie sonst keinen Zugriff haben. Wir geben die Berechtigungen f\u00fcr jede exponierte Anwendung auf und f\u00fchren einen exponierten Dienst nicht als root aus! Wenn Sie den Docker-Daemon als Nicht-Root-Benutzer steuern, erhalten Sie keine zus\u00e4tzliche Sicherheit. Der unprivilegierte Benutzer wird die Container ebenfalls als root spawnen. Das Verhalten des Stacks ist identisch. $ su # umask 0022 # <- \u00dcberpr\u00fcfen, dass es 0022 ist # cd /opt # git clone https://github.com/mailcow/mailcow-dockerized # cd mailcow-dockerized 3. Erzeugen Sie eine Konfigurationsdatei. Verwende einen FQDN ( host.domain.tld ) als Hostname, wenn du gefragt wirst. ./generate_config.sh 4. \u00c4ndern Sie die Konfiguration, wenn Sie das wollen oder m\u00fcssen. nano mailcow.conf Wenn Sie planen, einen Reverse Proxy zu verwenden, k\u00f6nnen Sie zum Beispiel HTTPS an 127.0.0.1 auf Port 8443 und HTTP an 127.0.0.1 auf Port 8080 binden. M\u00f6glicherweise m\u00fcssen Sie einen vorinstallierten MTA stoppen, der Port 25/tcp blockiert. Siehe dieses Kapitel , um zu erfahren, wie man Postfix rekonfiguriert, um nach einer erfolgreichen Installation neben mailcow zu laufen. Einige Updates modifizieren mailcow.conf und f\u00fcgen neue Parameter hinzu. Es ist schwer, in der Dokumentation den \u00dcberblick zu behalten. Bitte \u00fcberpr\u00fcfen Sie deren Beschreibung und fragen Sie, wenn Sie unsicher sind, in den bekannten Kan\u00e4len nach Rat. 4.1. Benutzer mit einer MTU ungleich 1500 (z.B. OpenStack): Wenn Sie auf Probleme und seltsame Ph\u00e4nomene sto\u00dfen, \u00fcberpr\u00fcfen Sie bitte Ihre MTU. Bearbeiten Sie docker-compose.yml und \u00e4ndern Sie die Netzwerkeinstellungen entsprechend Ihrer MTU. F\u00fcgen Sie den neuen Parameter driver_opts wie folgt hinzu: Netzwerke: mailcow-network: ... driver_opts: com.docker.network.driver.mtu: 1450 ... 4.2. Benutzer ohne ein IPv6-aktiviertes Netzwerk auf ihrem Hostsystem: Einschalten von IPv6. Endlich. Wenn Sie kein IPv6-f\u00e4higes Netzwerk auf Ihrem Host haben und Sie sich nicht um ein besseres Internet k\u00fcmmern (hehe), ist es empfehlenswert, IPv6 zu deaktivieren f\u00fcr das mailcow-Netzwerk, um unvorhergesehene Probleme zu vermeiden. 5. Ziehen Sie die Images und f\u00fchren Sie die Compose-Datei aus. Der Parameter -d wird mailcow starten: dockerized detached: docker-compose pull docker-compose up -d Geschafft! Sie k\u00f6nnen nun auf https://${MAILCOW_HOSTNAME} mit den Standard-Zugangsdaten admin + Passwort moohoo zugreifen.

Die Datenbank wird sofort initialisiert, nachdem eine Verbindung zu MySQL hergestellt werden kann. Ihre Daten bleiben in mehreren Docker-Volumes erhalten, die nicht gel\u00f6scht werden, wenn Sie Container neu erstellen oder l\u00f6schen.

Spam & Ham lernen \u00b6 Rspamd lernt, ob es sich um Spam oder Ham handelt, wenn Sie eine Nachricht in oder aus dem Junk-Ordner in ein anderes Postfach als den Papierkorb verschieben. Dies wird durch die Verwendung des Sieve-Plugins \"sieve_imapsieve\" und Parser-Skripte erreicht. Rspamd liest auch automatisch Mails, wenn eine hohe oder niedrige Punktzahl erkannt wird (siehe https://rspamd.com/doc/configuration/statistic.html#autolearning ).

Sowohl WebAuthn als auch Yubi OTP funktionieren gut mit dem fantastischen Yubikey . W\u00e4hrend Yubi OTP eine aktive Internetverbindung und eine API ID + Schl\u00fcssel ben\u00f6tigt, funktioniert WebAuthn mit jedem Fido Security Key, kann aber nur verwendet werden, wenn der Zugriff auf mailcow \u00fcber HTTPS erfolgt. WebAuthn und Yubi OTP unterst\u00fctzen mehrere Schl\u00fcssel pro Nutzer. Als dritte TFA-Methode verwendet mailcow TOTP: zeitbasierte Einmal-Passw\u00f6rter. Diese Passw\u00f6rter k\u00f6nnen mit Apps wie \"Google Authenticator\" generiert werden, nachdem zun\u00e4chst ein QR-Code gescannt oder das gegebene Geheimnis manuell eingegeben wurde. Als Administrator k\u00f6nnen Sie den TFA-Login eines Domain-Administrators vor\u00fcbergehend deaktivieren, bis dieser sich erfolgreich eingeloggt hat. Der f\u00fcr die Anmeldung verwendete Schl\u00fcssel wird in gr\u00fcner Farbe angezeigt, w\u00e4hrend andere Schl\u00fcssel grau bleiben. Informationen zum Entfernen von 2FA finden Sie hier . Yubi OTP \u00b6 Die Yubi API ID und der Schl\u00fcssel werden mit der Yubico Cloud API abgeglichen. Bei der Einrichtung von TFA werden Sie nach Ihrem pers\u00f6nlichen API-Konto f\u00fcr diesen Schl\u00fcssel gefragt. Die API-ID, der API-Schl\u00fcssel und die ersten 12 Zeichen (Ihre YubiKeys ID in modhex) werden in der MySQL-Tabelle als Geheimnis gespeichert. Beispiel-Einrichtung \u00b6 Als erstes muss der YubiKey f\u00fcr die Verwendung als OTP-Generator konfiguriert werden. Laden Sie dazu den YubiKey Manager von der Yubico Website herunter: hier Im Folgenden konfigurieren Sie den YubiKey f\u00fcr OTP. \u00dcber den Men\u00fcpunkt Anwendungen -> OTP und einem Klick auf den Konfigurieren Button. W\u00e4hlen Sie im folgenden Men\u00fc Credential Type -> Yubico OTP und klicken Sie auf Next . Setzen Sie ein H\u00e4kchen in die Checkbox Use serial , generieren Sie eine Private ID und einen Secret key \u00fcber die Schaltfl\u00e4chen. Damit der YubiKey sp\u00e4ter validiert werden kann, muss auch das H\u00e4kchen in der Upload Checkbox gesetzt werden und klicken Sie dann auf Finish . Nun \u00f6ffnet sich ein neues Browserfenster, in dem Sie unten im Formular ein OTP Ihres YubiKey eingeben m\u00fcssen (auf das Feld klicken und dann auf Ihren YubiKey tippen). Best\u00e4tigen Sie das Captcha und laden Sie die Daten auf den Yubico-Server hoch, indem Sie auf 'Hochladen' klicken. Die Verarbeitung der Daten wird einen Moment dauern. Nachdem die Generierung erfolgreich war, werden Ihnen eine Client ID und ein Secret key angezeigt, notieren Sie sich diese Informationen an einem sicheren Ort. Nun k\u00f6nnen Sie Yubico OTP-Authentifizierung aus dem Dropdown-Men\u00fc in der mailcow UI auf der Startseite unter Zugang -> Zwei-Faktor-Authentifizierung ausw\u00e4hlen. In dem sich nun \u00f6ffnenden Dialog k\u00f6nnen Sie einen Namen f\u00fcr diesen YubiKey eingeben und die zuvor notierte Client ID sowie den Secret key in die vorgesehenen Felder eintragen. Geben Sie schlie\u00dflich Ihr aktuelles Kontopasswort ein und ber\u00fchren Sie nach Auswahl des Feldes Touch Yubikey die Schaltfl\u00e4che Ihres YubiKey. Herzlichen Gl\u00fcckwunsch! Sie k\u00f6nnen sich nun mit Ihrem YubiKey in die mailcow UI einloggen! WebAuthn (U2F, Ersatz) \u00b6 Warning Seit Februar 2022 hat Google Chrome die Unterst\u00fctzung f\u00fcr U2F aufgegeben und die Verwendung von WebAuthn standardisiert. Die WebAuthn API (der Ersatz f\u00fcr U2F) ist seit dem 21. Januar 2022 Teil von mailcow, wenn Sie also den Key \u00fcber Februar 2022 hinaus nutzen wollen, sollten Sie ein Update mit der update.sh in Betracht ziehen. Um WebAuthn zu nutzen, muss der Browser diesen Standard unterst\u00fctzen: Edge (>=18) Firefox (>=60) Chrome (>=67) Safari (>=13) Opera (>=54) Die folgenden mobilen Browser unterst\u00fctzen diesen Authentifizierungstyp: Safari auf iOS (>=14.5) Android-Browser (>=97) Opera Mobil (>=64) Chrome f\u00fcr Android (>=97) Quellen: caniuse.com , blog.mozilla.org WebAuthn funktioniert auch ohne Internetverbindung. Was passiert mit meinem registrierten Fido Security Key nach dem Update von U2F auf WebAuthn? \u00b6 Warning Mit dem neuen U2F-Ersatz (WebAuthn) m\u00fcssen Sie Ihren Fido Security Key neu registrieren, zum Gl\u00fcck ist WebAuthn abw\u00e4rtskompatibel und unterst\u00fctzt das U2F-Protokoll. Im Idealfall sollten Sie beim n\u00e4chsten Einloggen (mit dem Schl\u00fcssel) ein Textfeld erhalten, das besagt, dass Ihr Fido Security Key aufgrund des Updates auf WebAuthn entfernt und als 2-Faktor-Authentifikator gel\u00f6scht wurde. Aber keine Sorge! Sie k\u00f6nnen Ihren bestehenden Schl\u00fcssel einfach neu registrieren und ihn wie gewohnt verwenden. Sie werden wahrscheinlich nicht einmal einen Unterschied bemerken, au\u00dfer dass Ihr Browser die U2F-Deaktivierungsmeldung nicht mehr anzeigt. Deaktivieren inoffizieller unterst\u00fctzter Fido Security Keys \u00b6 Mit WebAuthn gibt es die M\u00f6glichkeit, nur offizielle Fido Security Keys zu verwenden (von den gro\u00dfen Marken wie: Yubico, Apple, Nitro, Google, Huawei, Microsoft, usw.) zu verwenden. Dies dient in erster Linie der Sicherheit, da es Administratoren erm\u00f6glicht, sicherzustellen, dass nur offizielle Hardware in ihrer Umgebung verwendet werden kann. Um diese Funktion zu aktivieren, \u00e4ndern Sie den Wert WEBAUTHN_ONLY_TRUSTED_VENDORS in mailcow.conf von n auf y und starten Sie die betroffenen Container mit docker-compose up -d neu. Die mailcow wird nun die Vendor-Zertifikate verwenden, die sich in Ihrem mailcow-Verzeichnis unter data/web/inc/lib/WebAuthn/rootCertificates befinden. Beispiel: \u00b6 Wenn Sie die offiziellen Hersteller-Ger\u00e4te nur auf Apple beschr\u00e4nken wollen, brauchen Sie nur das Apple Hersteller-Zertifikat im data/web/inc/lib/WebAuthn/rootCertificates . Nachdem Sie alle anderen Zertifikate gel\u00f6scht haben, k\u00f6nnen Sie WebAuthn 2FA nur noch mit Apple-Ger\u00e4ten aktivieren. Das ist f\u00fcr jeden Hersteller gleich, also w\u00e4hlen Sie aus, was Ihnen gef\u00e4llt (wenn Sie es wollen). Eigene Zertifikate f\u00fcr WebAuthn verwenden \u00b6 Wenn du ein g\u00fcltiges Zertifikat vom Hersteller deines Schl\u00fcssels hast, kannst du es auch zu deiner Mailcow hinzuf\u00fcgen! Kopieren Sie einfach das Zertifikat in den data/web/inc/lib/WebAuthn/rootCertificates Ordner und starten Sie Ihre Mailcow neu. Nun sollten Sie in der Lage sein, auch dieses Ger\u00e4t zu registrieren, obwohl die \u00dcberpr\u00fcfung f\u00fcr die Herstellerzertifikate aktiviert ist, da Sie das Zertifikat manuell hinzugef\u00fcgt haben. Ist es gef\u00e4hrlich, den Vendor Check deaktiviert zu lassen? \u00b6 Nein, das ist es nicht! Diese Herstellerzertifikate werden nur zur \u00dcberpr\u00fcfung der Originalhardware verwendet, nicht zur Absicherung des Registrierungsprozesses. Wie Sie in diesen Artikeln lesen k\u00f6nnen, hat die Deaktivierung nichts mit der Software-Sicherheit zu tun: - https://developers.yubico.com/U2F/Attestation_and_Metadata/ - https://medium.com/webauthnworks/webauthn-fido2-demystifying-attestation-and-mds-efc3b3cb3651 - https://medium.com/webauthnworks/sorting-fido-ctap-webauthn-terminology-7d32067c0b01 Letztendlich ist es aber nat\u00fcrlich Ihre Entscheidung, ob Sie dieses H\u00e4kchen deaktiviert oder aktiviert lassen. TOTP \u00b6 Die bekannteste TFA-Methode, die meist mit einem Smartphone verwendet wird. Um die TOTP-Methode einzurichten, loggen Sie sich in die Admin UI ein und w\u00e4hlen Sie Time-based OTP (TOTP) aus der Liste. Nun \u00f6ffnet sich ein Modal, in dem Sie einen Namen f\u00fcr Ihr 2FA-\"Ger\u00e4t\" (Beispiel: John Deer's Smartphone) und das Passwort des betroffenen Admin-Kontos (mit dem Sie derzeit eingeloggt sind) eingeben m\u00fcssen. Sie haben zwei verschiedene Methoden, um TOTP f\u00fcr Ihr Konto zu registrieren: 1. Scannen Sie den QR-Code mit Ihrer Authenticator App auf einem Smartphone oder Tablet. 2. Verwenden Sie den TOTP-Code (unter dem QR-Code) in Ihrem TOTP-Programm oder Ihrer App (wenn Sie keinen QR-Code scannen k\u00f6nnen). Nachdem Sie den QR- oder TOTP-Code in der TOTP-App/dem TOTP-Programm Ihrer Wahl registriert haben, m\u00fcssen Sie nur noch den nun generierten TOTP-Token (in der App/dem Programm) als Best\u00e4tigung in der mailcow UI eingeben, um die TOTP 2FA endg\u00fcltig zu aktivieren, ansonsten wird sie nicht aktiviert, obwohl der TOTP-Token bereits in Ihrer App/ Ihrem Programm generiert wurde.","title":"Zwei-Faktoren-Authentifizierung"},{"location":"de/manual-guides/mailcow-UI/u_e-mailcow_ui-tfa/#yubi-otp","text":"Die Yubi API ID und der Schl\u00fcssel werden mit der Yubico Cloud API abgeglichen.

Info Die Verwendung der untenstehenden Site-Konfigurationen wird acme-Anfragen an mailcow weiterleiten und es die Zertifikate selbst verwalten lassen. Der Nachteil der Verwendung von mailcow als ACME-Client hinter einem Reverse-Proxy ist, dass Sie Ihren Webserver neu laden m\u00fcssen, nachdem acme-mailcow das Zertifikat ge\u00e4ndert/erneuert/erstellt hat. Sie k\u00f6nnen entweder Ihren Webserver t\u00e4glich neu laden oder ein Skript schreiben, um die Datei auf \u00c4nderungen zu \u00fcberwachen.

Die Container m\u00fcssen ihre Datenbanken und Konfigurationsdateien erstellen. Dies kann bis zu 1 Minute und mehr dauern. Bemerkungen \u00b6 Neue Listen werden von Postfix nicht sofort erkannt \u00b6 Wenn man eine neue Liste anlegt und versucht, sofort eine E-Mail zu versenden, antwortet postfix mit Benutzer existiert nicht , weil postfix die Liste noch nicht an Mailman \u00fcbergeben hat. Die Konfiguration unter /opt/mailman/core/var/data/postfix_lmtp wird nicht sofort aktualisiert. Wenn Sie die Liste sofort ben\u00f6tigen, starten Sie postifx manuell neu: cd /opt/mailcow-dockerized docker-compose restart postfix-mailcow Update \u00b6 mailcow hat sein eigenes Update-Skript in /opt/mailcow-dockerized/update.sh , siehe die Dokumentation . F\u00fcr Mailman holen Sie sich einfach die neueste Version aus dem github repository . Sicherung \u00b6 mailcow hat ein eigenes Backup-Skript. Lies die Docs f\u00fcr weitere Informationen.
