Mails über Mailrelay einliefern

[sebastian at debianfan.de]

Guten Abend,

ich hab das letzte mal 1999 sowas eingerichtet - ich bin etwas aus der 
Übung.

Ein Testsystem soll seine Mails nicht selbst senden sondern über ein 
Mailrelay arbeiten - d.h. Anmeldung per Login&Passwort und analog meinem 
Mailprogramm auf meinem Mobiltelefon seine Mails dort abkippen.

Das Relay funktioniert - das ist das gleiche über welches ich sonst auch 
normalerweise Mails versende - der Fehler liegt eher im Testsystem.

Ich vermute den Fehler in der main.cf
