Hallo,

ich habe mit Amavisd/Spamassassin ein Problem: Einige Mails deren Hits Wert über dem in der
Amavisd.conf angegebenen Wert liegt werden trotzdem zugestellt. Folgende Versionen kommen zum
Einsatz: amavisd-new-2.1.2; SpamAssassin version 3.0.4 (Suse 9.2).

habt Ihr da eine Idee? Wenn noch irgendwas fehlt reiche ich das natürlich gerne nach!

Mir fällt vorallem diese Zeile auf:

$sa_tag_level_deflt = -999;

Bist Du Dir denn sicher, daß Du keine local.cf von SpamAssassin irgendwo rumfliegen hast? (z.B. in /etc/spamassassin/local.cf)
Dort könnte noch ein anderes Level eingestellt sein.
