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 Red Hat Enterprise Linux 9 (Plow). 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 Red Hat Enterprise Linux 9 (Plow).

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.
