FAQ

Wann sollte ich master.cf verwenden?

Nutze sie, um eine fehlende Default-Datei wiederherzustellen, zu prüfen, was ausgeliefert wurde, oder sie gegen deine aktuelle Postfix-Config zu diffen.

Wie stelle ich die Defaults von Postfix wieder her?

Lad die Datei runter, sichere die aktuelle in /etc/postfix/master.cf, ersetze sie und lade Postfix neu oder starte es neu.

Ist master.cf für den produktiven Einsatz geeignet?

Das ist der Hersteller-Default für CentOS Stream 9. Nimm sie als Basis und prüf Security- und Performance-Einstellungen, bevor du sie produktiv nutzt.

Wie unterscheidet sich das von anderen OS-Versionen?

Defaults variieren je nach Distro und Version. Diese Version passt zu CentOS Stream 9.

Kann ich das fürs Troubleshooting von Postfix nutzen?

Ja. Diff es gegen deine Version, finde Abweichungen und stell nur die Teile wieder her, die du brauchst.
