Hallo,

nachdem mein Server jetzt läuft, habe ich das Problem, dass Emails auch ohne Authentifizierung verschickt werden können.
Zu Authentifizierung nutze ich SASL und die /etc/shadow. Bisher dachte ich des geht alles, aber scheinbar ist da noch irgendwo nen Fehler.

Wer kann mir da auf die Sprünge helfen?

Anbei mal das ergebnis von postconf -n
