[Postfixbuch-users] Subdomains und relay_recipient_maps

[Joachim Schoenberg]

Hallo Liste,

ich betreue ein Mailrelay fuer mehrere Institute.
Es kam der Wunsch auf, daß Mails an Empfänger in
Subdomains umgeschrieben und damit zustellbar werden.
Ich hatte das über

canonical_maps = regexp:/etc/postfix/canonical_regexp

geloest mit Eintraegen wie

/@.*\.pdi-berlin\.de/  @pdi-berlin.de 

"Meine" Domains stehen in relay_domains, also z. B.

pdi-berlin.de	dummy

Ich stelle jetzt fest, daß zwar korrekt umgeschrieben wird, aber die 
Abfrage der relay_recipient_maps erfolgt nicht bzw. vorher (vermutlich,
weil die canonical maps erst durch "cleanup" bearbeitet werden).
Wie kann ich das Abscheiden der Subdomains _vor_ der Abfrage gueltigen Nutzer
vornehmen - oder brauche ich einen grundsaetzlich anderen Ansatz?
