<p>Bitte erstellen Sie eine neue Datei <code>data/conf/postfix/extra.cf</code> für Überschreibungen oder zusätzliche Inhalte zur <code>main.cf</code>.</p>
<p>Postfix wird sich einmal nach dem Start von postfix-mailcow über doppelte Werte beschweren, dies ist beabsichtigt.</p>
<p>Syslog-ng wurde so konfiguriert, dass es diese Warnungen ausblendet, während Postfix läuft, um die Log-Dateien nicht jedes Mal mit unnötigen Informationen zu spammen, wenn ein Dienst benutzt wird.</p>
<p>Starten Sie <code>postfix-mailcow</code> neu, um Ihre Änderungen zu übernehmen:</p>
