Hallo, erst einmal meinen Dank an Andreas. Vielleicht kannst Du mir hier auch einen 'Schubs in die richtige Richtung geben'? Es ist nicht das erste Mal, dass ich mich damit beschäftige. Nun dachte ich, mit selbst übersetzten Paketen sollte es funktionieren. Aber leider weit gefehlt. Nach http://postfix.state-of-mind.de/patrick.koetter/smtpauth und auch dem Postfixbuch von Peer Heinlein habe ich alle Einstellungen in der main.cf vorgenommen, cyrus-sasl ist installiert, die Module vorhanden, aber postfix bietet mir nur PLAIN und LOGIN. rw@tuxel:~> telnet 192.168.2.2 smtp Trying 192.168.2.2...
