[Postfixbuch-users] Mail an virtuelle User senden.

[hotten]

Also nochmal Hallo!!
Ich hoffe jetzt erfülle ich alle regularien der Liste.

Mein Problem:
Wenn ich versuche mails an virtuelle Benutzer über pstfix zu schicken 
bekomme ich immer die Fehlermeldung

den mx für die domain studenten.hs-bremerhaven.de habe ich, denke ich,

Ich habe so überhaupt keine Idee woran da liegen könnte. Weiß jemand Rat

PS:

Für meinen bis jetzt geposteten Müll bitte ich um Entschuldigung!!
Werde mich bemühen nicht mehr so wirr zu sein!!

Gruss
