Hallo liebe Gemeinde,
nachdem ich gezwungen war meinen Server neu aufzusetzen, habe ich das große Problem, dass dieser keine Emails von externen Domains mehr empfängt. Interner Empfang / Versand, sowie Versand nach aussen funktionieren. Aus den mail logs geht der fehler nicht wirklich hervor.

Für jede Idee wäre ich sehr dankbar, da ich schon am verzweifeln bin.
Bei dem Server handelt es sich um einen Root Server von Server4You.
Für die Grundinstallation habe ich diese Anleitung verwendet:
Der Perfekt Server - Debian Squeeze (Debian 6.0) mit BIND und Courier [ISPConfig 3]
Hier noch ein paar Konfigurationseinstellungen von dem Server:
/etc/postfix/main.cf
/etc/courier/imapd.cnf
/etc/courier/pop3d.cnf
