Okay, siehe [1]

Richtig.

mydestination = localhost, $myhostname
myhostname = myhost.irgendwas.org

Und da beißt sich nach meinem Verständnis der Hund in seinen eigenen
Schwanz: Sowohl auf Host A als auch auf Host B ist nämlich dieselbe
Domain eingetragen. Ich kann die Domain allerdings nicht gleichzeitig in
der mydestination und der virtual_alias_domains eintragen. Vielleicht
wirds durch die getmail-Konfiguration [2] verständlicher.

Die relevanten Postfix-Logs findest du unter [3] oder, wenn die
Zeilenumbrüche stören, unter http://paste.debian.net/74890.
