Postfix - Relay access denied

Gut, jetzt das nächste Problem

Habe einen Mailserver mit Postifx, Dovecot, fetchmail und ich kann auch E-Mails empfangen.
Nur senden kann ich keine!

Sep 3 16:27:35 localhost postfix/smtpd[7223]: NOQUEUE: reject: RCPT from unknown[192.168.0.2]: 554 5.7.1 <info@emailadresse.de>: Relay access denied; from=<backup@maildomaine.de> to=<info@emailadresse.de> proto=ESMTP helo=<inc1wt5o4iagv1>


Authentifizierung geht per saslauthd und der läuft auch.
Habe auch die db per postmap erstellt
Format: mailserver mailuser:password

woran kann es noch liegen, soll ich euch irgendein config File posten ?

Hier mal die main.cf die ich aus HOW2's und FAQ's genommen habe!
