Webmail fehler RC6!

[kintaro]

Hallo,

Ich habe mal wieder ein Problem mit meinem Server.
Das Problem ist, wenn ich mich im Webmail einloggen will, kommt Folgender Fehler:

ERROR: Connection dropped by IMAP server.

Nur Meldet mir ISPCP das IMAP läuft, habe es auch manuell nochmal neugestartet.

Edit:
Postfix verweigert komplett den Dienst

postconf -n ergab folgendes:
