Hallo Arne,
wenn ich dir hier die ursprünglichen main.cf und master.cf eines jungfräulichen Debian 11 für KeyHelp 24.2 zur Verfügung stelle, reicht dir das als Abgleich? Du kannst Sie ja durch ein diff jagen und schauen, wo du ggf. Anpassungen vornehmen musst.
Wenn du die Dateien auf dem Server dann angepasst hast, am besten nochmal bei "Konfiguration -> E-Mail-Server" und "Konfiguration -> TLS-Version & -Ciphers" auf "Speichern" klicken, so dass deine dort getroffenen Einstellungen entsprechend in die Dateien übernommen werden.
