[Postfixbuch-users] ungültige empfänger email-adresse - mail an postmaster, wie kann man das stoppen?

[Oliver Strixner]

Hallo,

habe festgestellt, das viele Anfragen von postfix bearbeitet werden wenn eine ungültige email-adresse zur zustellung kommt, dabei entstehen ca 500 Mails an den Postmaster wie beigefügt.

A) Kann das so einstellen, das ungültige Empfänger Adressen gleich rejectet werden ohne weitere Bearbeitung?

B) Kann ich mir selbst eine Liste erstellen, in der ich die Dauer-SPAM-Besucher (email-adresse und/oder domain) eintragen kann und postfix, diese dann sofort rejectet?
