[Postfixbuch-users] Möglichkeiten gegen nicht zustellbarer Bounces?

[Julian Pawlowski]

Hallo Liste!

In den letzten Wochen hängen bei mir in der Mailqueue verstärkt mails fest,
die eine bounce-antwort auf mails sind, die bei mir nicht zugestellt werden
konnten.

für mich stellen sich dabei 2 fragen: warum wurden die mails überhaupt
angenommen, wenn das postfach nicht existiert?
und: was kann man gegen diese art von bounces unternehmen?

hier mal kurz meine aktuelle config:

[code]
