[Postfixbuch-users] Konfiguration Postfix Backscatter?

[Susanne Kaufmann]

Hallo zusammen,

ich habe letztens einen Server neu aufgesetzt und habe seitdem Probleme mit
Backscatter-Mails. Ich kann mir das aber nicht so ganz erklären. Evtl.
könnte jemand einmal einen Blick auf meine Postfix-Konfiguration werfen.
Vielen Dank schon einmal im Voraus.

Viele Grüße,
Susanne
