[Postfixbuch-users] Problemstellung zentraler Emailserver mit Spam- und Virenschutz

[Sven Roth]

Hallo Andreas,

> Hier würden logfiles und postconf -n helfen.

Habe mal einen neuen SuSE 8.2 Testrechner eingerichtet. Postfix und
Fetchmail mit YaST2 installiert und die Angaben für den Mail Transport Agent
(Postfix) in YaST eingetragen. Damit ist die Konfiguration eigentlich
"original" und nicht von mir umgebaut. Cyrus-IMAP, AVMailGate usw. sind
nicht installiert.

Trotzdem scheint irgendwas die Empfängeradresse umzuschreiben! Die
Emailadressen werden in "user at localhost" und "user at localhost.netzwerk.local"
umgebaut, die ursprüngliche Empfängeradresse empfaenger at gmx.net wird nicht
mehr gezeigt.

Mit "less /var/spool/mail/user" habe ich mir die Email angesehen.

Fetchmail wird mit

server pop.gmx.net proto pop3 user empfaenger at gmx.net pass xxx is "user"
here norewrite

aufgerufen.

Das ist ein Test mit Fetchmail und Postfix für postfixbuch-users.

Jetzt bin ich ratlos, weil ich dachte, eine neue Installation brächte die
Erhellung.

Bis denn
