Ok, ich habe das Problem gelöst.
Habe einfach den SMTP-Relay Server leer gelassen.

Hallo, mal wieder ein Problem.
Seit cs. 3 Monaten sendet der Server keine Mails mehr, der Fehler ist immer der Gleiche:

Nov 29 15:17:55 ksxxx postfix/smtp[8466]: F1D0A54FC4: to=, relay=smtp.kimsufi.com[213.186.33.20]:25, delay=0.07, delays=0.03/0.01/0.02/0.01, dsn=5.0.0, status=bounced (host smtp.kimsufi.com[213.186.33.20] said: 553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) (mail609.ha.ovh.net, smtpauth: no) (in reply to MAIL FROM command))
Nov 29 15:17:55 ksxxx postfix/cleanup[8464]: 0EB8A54FC5: message-id=<20091129141755.0EB8A54FC5@xxx.kimsufi.com>

Hat da jemand eine Lösung, den http://hilfe.ovh.de/EmailProblemeUnd hat irgendwie nicht so viel genützt.
Die Postfix Config:

# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

biff = no
