< 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 >

< 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 >
