[Postfixbuch-users] Mails weiterreichen an anderen Host weiterleiten

[Andreas Moroder]

Hallo,

die gesamte Mail ( Ein und Ausgang ) ist derzeit über unseren Mailserver
( mail.sb-brixen.it ) gelaufen. Nun müsste ein Teil der Mail auf einen
anderen Server ( xpr30 ) durchgereicht werden, wenn in der Adresse der
Hostname XPR30 mit angegebene wurde, so z.B.: name at xpr30.sb-brixen.it.

Wie muss ich postfix konfigurieren, dass er diese und nur diese Mails
weiterreicht ?

Unten folgt meine derzeitige Konfiguration

Grüße
Andreas
