[SOLVED] User unknown in local recipient table

[legolas]

So nach Tagelangem Studieren des Forums und Howto's hab ich mein Problem nicht lösen können.
Also ich kann Emails versenden aber nicht Empfangen. Der Versender bekommt immer die Mail zurück mit dieser Meldung :

Quote:MailEnable: Message could not be delivered to some recipients.
The following recipient(s) could not be reached:

Recipient: [SMTP:webmaster@delfinhosting.de]
Reason: Remote SMTP Server Returned: 550 5.1.1 <webmaster@delfinhosting.de>: Recipient address rejected: User unknown in local recipient table

Ich nutze RC7 auf einem Debian Etch 32bit (minimal installation) Root-Server.
System ist frisch instaliert und das Howto zum wechsel auf Dovecot wurde zur vermutlichen Problemlösung eingebaut. Webmin ist zur weiteren Administration vorhanden.

mail.warn

mail.err gibt die selbe untere meldung aus.
ispcp-dovecot-mngr ist nach Howto eingerichtet + imaps und pops.

hier noch meine main.cf

Ich weiss das das Thema schon etliche male schon besprochen wurde aber wie oben schon gesagt aber keine doku, post oder wiki hat das problem lösen können.
Wenn irgendwelche Infos benötigt werden. geb ich die gerne hier an. Aber bitte Lösungen Newbie-tauglich posten wenn möglich.
hoffe das mir jemand helfen kann.
