[Postfixbuch-users] postfix und sender adress rejected

[Andreas Reschke]

Hallo Leute,
ich habe vor ca. 1 Monat Mailman und vor ca. 3 Monate postfix aufgesetzt und 
seither hat alles einwandfrei funktioniert. Durch Zufall habe ich in den Logs 
folgende Fehlermeldung gesehen:
Sep  4 08:55:40 mail postfix/qmgr[30068]: 64F6290088: 
from=<mailman-bounces at mail.reschke.lan>, size=2699, nrcpt=1 (queue active)
Sep  4 08:55:40 mail postfix/smtp[14669]: 64F6290088: 
to=<andreas.reschke at behrgroup.com>, 
relay=securemail.behrgroup.com[194.99.122.168], delay=273337, status=deferred 
(host securemail.behrgroup.com[194.99.122.168] said: 450 
<mailman-bounces at mail.reschke.lan>: Sender address rejected: Domain not found 
(in reply to RCPT TO command))

Der Name mail.reschke.lan ist der interne Name des Rechners der extern 
mail.rirasoft.de heißt. Was läuft hier falsch?
