Postfix - unknown service: smtp/tcp & cannot find your hostname

Huhu ich hoffe mir kannt jemand weiter helfen. Das Wochende schlage ich mich schon mit meinen Mailserver rum der einfach nicht mehr laufen will :(

System: Debian Squeeze (6) mit Froxlor + Courier/Postfix + Amavis (ClamAV & Spamassain's etc)

Courier läuft problemlos, Mails die lokal laufen werden zugestellt und können abgeholt werden (POP/IMAP).

Problem macht die Kommunikation nach außen mit SMTP.

E-Mail Empfang - Logs

Code: 
postfix/smtpd[31072]: connect from unknown[89.xx.xx.xx]
postfix/smtpd[31072]: NOQUEUE: reject: RCPT from unknown[89.xx.xx.xx]: 450 4.7.1 Client host rejected: cannot find your hostname, [89.xx.xx.xx]; from=<adresse@domain2.de> to=<info@domain1.de> proto=ESMTP helo=<mail.domain2.de>
postfix/smtpd[31072]: disconnect from unknown[89.xx.xx.xx]

Der Empfang wird immer so abgelehnt, obwohl es korrekt ist. Ich kann mit meinen Server sogar selbst per "resolveip 89.xx.xx.xx" die Domain -> mail.domain2.de auflösen und umgekehrt zeigt es auch auf die IP.

Es gibt drei mögliche Auslöser für das Problem:
- Defektes Filesystem vor ca. 1 Woche bei dem zwei Inodes behoben wurden (Grund: HDD defekte Sektoren).
- Installation von "mono-complete" Paket per apt-get vom Wheezy Repository, was aber nicht problematisch sein sollte, da es keine Abhängigkeiten zu installierten Paketen gab und auch keine anderen Pakete geupdatet wurden worauf ich auch extra achtete um Versionskonflikte zu vermeiden.
-Irgendwelche Datein verschwunden da nach dem HDD Problem die Festplatte(n) getauscht wurden mitsamt RaidMigration (Raid1 -> Raid10) und RaidExpansion (Vergrößerung des Raids). Dieses dauert ja etwas länger und weiß nicht wie gut der Raid Controller (Adaptec) sowas auf einem Produktivserver verkraftet in bezug auf permanente Daten veränderungen.

Aufgetreten ist es plötzlich nachdem Reboot des Server nachdem "mono" installieren. Durch das erneute Laden der Programme können aber auch die anderen Sachen eventuell ne Auswirkung haben (irgendwelche Datein sind korrupt o.ä.)

Geprüft habe ich folgendes:
- DNS auf dem Server funktioniert allgemein (Ping mit Domains/ Resolveip etc.), aber scheinbar nicht beim Postfix (siehe "cannot find your hostname").
- Nameserver sind in /etc/resolv.conf und /var/spool/spool/postfix/etc/resolv.conf identisch und funktionieren, auch mit DNS von Google getestet.
- Er kennt den "smtp" Service nicht - in /etc/services und /var/spool/spool/postfix/etc/services ist es aber mit TCP auf Port25 bei beiden vorhanden. Auch das hinzufügen z.B. nochmal extra mit UDP brachte auch keine Verbesserung.
- Rückspielen von Backups (1 Tag vor Ausfall, 1 Monate vor Ausfall und 3 Monate vor Ausfall) brachten auch ebenfalls immer wieder den selben Fehler beim Postfix.
- Amavis und die ganze AntiSpam Klamotten sind auch nicht der Fehler, ohne Verweis auf Amavis verhält sich der Postfix ebenfalls so.
