[Postfixbuch-users] Verschicke Spams, Open relay?

[Susanne Kaufmann]

Hallo zusammen,

ich hatte vor kurzem schon einmal das Problem, dass Spams über meinen Server
versendet wurden. Jetzt habe ich meine Konfiguration des Postfix angepasst
und wie ich gehofft hatte abgeschottet. Ich habe auch mal über abuse.net auf
ein Open Relay testen lassen - nichts. Aber trotzdem werden Spam-Emails mit
falschem Absender verschickt. Ich habe mal den Logfile-Ausschnitt einer
dieser Spam-Mails angehängt. Diese Email dürfte eigentlich niemals so
durchgehen....tut sie aber. Oder habe ich einen Fehler im SASL, denn in der
vorletzten Zeile heißt es " permit_sasl_authenticated status=1".

Auf Wunsch hänge ich gerne meine Konfiguration noch an.

Viele Grüße und schon einmal vielen Dank für jeden Tipp,

Susanne
