[Postfixbuch-users] amavis & Open relay? Nonlocal recips but not originating:

[spamvoll at googlemail.com]

Hallo..

mein Mailserver läuft seit fast einem Jahr ohne Probleme, aber seit
ein paar Tagen klappt der Versand von einigen mails nichtmehr.
amavisd rejected die mail als SPAM, interessanter weise kann ich genau
die gleiche mail aber an andere Empfänger versenden.


In der Log sieht das so aus:

Hat hier jemand eine Idee warum das bei einer Handvoll EMails passiert
? Der Rest klappt wunderbar.. auch der Versand dieser einer Mail an
beliebige andere Empfänger (extern oder intern) funktioniert
Problemlos

Viele Grüße
