Postfix SMTP Unauthentifizierte Benutzer abweisen

Hallo Leute,

Habe es nach einigen Monaten des Kopfzerbrechens endlich geschafft Postfix so zu Konfigurieren, dass ich E-Mails empfangen und senden kann.

Nun habe ich allerdings ein Problem: Jeder hat die Möglichkeit ob Authentifiziert oder nicht, E-Mails zu versenden. Dies würde ich gern ändern, deshalb frage ich euch: Wie muss ich meine Konfiguration anpassen?

The_Nero danke dir schon mal.

Hab es jetzt soweit hin bekommen, dass ich keine Mails mehr senden kann, wenn ich nicht Authentifiziert bin. Allerdings kann ich keine Mails mehr empfangen. Aus reiner Intuition heraus, hätte ich jetzt mit check_recipient_access gearbeitet. Weis allerdings nicht, wie ich meine MySQL Konfiguration dazu schreiben muss.
Kannst du mir vielleicht dabei helfen?

Gruß
