Postfix (mail transport unavailable)

Guten Tag,
Ich habe einen Testserver mit Postfix in Betrieb (um mich in die Materie einzuarbeiten), bei welchem ich vor kurzem ein dist-upgrade gemacht habe. Vor dem Dist-Upgrade lief alles Problemlos... Das Problem ist nun, dass ich von diesem Server aus keine E-Mail nachrichten Extern versenden kann.

Die Nachricht wird vom Postfix korrekt entgegenommen wird jedoch niemals ausgeliefert. Was mich verwirrt ist, das erstige status=ok und nachher status = deferred(mail transport unavailable)

Vielen Dank für Ihre Hilfe und Zeit im Voraus
 
Vielen Dank für die rasche Antwort.

Procmail läuft aus meiner Sicht, es schreibt jedesmal einen Eintrag in ein logfile in welchem steht, dass er mail löscht, welche einen zu hohen spamgrades. Beispiel:
Code: 
From troyh@correo1.com  Tue Feb 17 17:09:54 2009
 Subject: *****SPAM***** =?windows-1251?B?UmVwbGljYSBXYXRjaGVz?=
  Folder: /dev/null                                                        7971


Ich habe nun den mailbox_command mit folgenden attributen erfolglos ausprobiert:
mailbox_command = /usr/bin/procmail -a "$EXTENSION"
mailbox_command = /usr/bin/procmail

Gibt es irgendwo eine Beispielkonfiguration von main.cf und master.cf welche sicher funktioniert?

Zum Content-Filter.
Wenn ich diesen auf den Ursprungsport 10025 ändere erscheint mir beim neustarten vom Confixx, die Meldung das der Port schon belegt ist. mit netstat -tlpen sieht man dan dass der Port von clamsmtpd belegt ist.

Ich habe nun den Port von 10026 auf 10025 geändert und damit Postfix startet den clamsmtpd dienst beendet. Nun läuft auf diesem Port ein Prozess namens: "31910/master"

Das Problem besteht leider immer noch im gleichen Rahmen --> (mail transport unavailable) zu hauf im /var/log/mail.log

Vielen Dank für deine Bemühungen.
