SpamAssassin schweigt sich aus

[Sebastian Schieke]

Hallo Allerseits,

in unserem Mailrelay-Setup haben wir SpamAssassin über Amavis eingebunden. Allerdings kommt es mir so vor, als ob SpamAssassin nicht (vollständig?) arbeitet. In der Amavis-Konfiguration ist eingestellt, dass Mails in jedem Fall mit entsprechenden Headern versehnen werden:

$sa_tag_level_deflt  = -1000;

Wenn ich es richtig interpretiere, sollten dann aber alle Mails, die es durch das Relay schaffen, entsprechende Header in der Art:

===================8<--------------------------------

X-Spam-Flag: NO
X-Spam-Score: -1.9
X-Spam-Level:

===================8<--------------------------------

aufweisen, oder verstehe ich das falsch?

Woran lässt sich feststellen, dass SpamAssassin tatsächlich funktioniert?

Anbei noch das main/master cf bundle:
