Hallo
Auf meinem OpenSuSE 11.1 habe ich postfix mit sasl konfiguriert, sowie mit clamd und amavis. Das Resultat war, dass ich einen offenen Relay-Server erstellt habe und mein Provider danach meinen Mailausgang kurz sperrte. Obwohl ich meine, alle Restrictions eingebaut zu haben, suche ich verzweifelt nach der Nadel im Heuhaufen. Auf meiner Firewall habe ich nun Port 25 von aussen dichtgemacht.
Ich poste hier mal die Konfig-Dateien, in der Hoffnung, dass ich hier Hilfe finde! Beim Einrichten hat mir mein Buch "Linux Kochbuch" von o'Reilly 2005 nicht wirklich viel geholfen, da vieles veraltet war und nicht SuSE bezogen.
(Meine Domain nenne ich hier zum Schutz vvvvvv.com)
Mein telnet-Test ergibt folgendes:
main.cf:Code:dvweb01:/etc/sasl2 # telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 dvweb01.vvvvvv.com ESMTP Postfix ehlo dvweb01.vvvvvv.com 250-dvweb01.vvvvvv.com 250-PIPELINING 250-SIZE 10240000 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN

Wie Du siehst genügen Tipps von zwei Fachleuten und es läuft. Von Auth scheinst Du auf jedenfall sehr wenig zu verstehen, denn immerhin habe ich das nach dem o'Reilly Linux Koch-Buch erstellt und es läuft auch.
