bounce-Mails

[daniel]

Hallo,

ich bekomme keine bounce-Mails. Die Mail nimmt folgenden Weg:

1. server1 verschickt Mail an nicht existierenden Empfänger direkt, mit 
dem Absender "service at example.org" wobei example.org auf server3 liegt
2. smtp-Server des Empfängers antwortet "gibts hier nicht", schickt 
Antwort an "service at example.org"
3. Server3 verantwortlich für example.org, ist ein Exchange, leitet alle 
Mails an "service at postfach-auf-server1" weiter
4. Server1 schickt die Mail wieder an Server3 weil er nicht 
verantwortlich dafür ist ....

Normales Verhalten, die Log davon ist weiter unten angehängt.

Ich hatte es kurz so gelöst, dass ich example.org in mydestinations auf 
server1 aufgenommen habe. Leider ist es so, dass Benutzer von server1 
auch Mails an Benutzer von Server3 schicken, diese kommen dann alle 
zurück als nicht zustellbar, da es diese Benutzer auf server1 nicht 
gibt.

Gibt es dafür eine Lösung?

OS von server1 ist ein Debian 9 mit Postfix 3.1.4.

Jetzt die Logs:
