Hello,

after updating the filters on mailing list manager to hold everything 
marked at list with:

X-Spam-Level: *

there were two other spam messages, coming with:

X-Spam-Level:

like:

http://lists.sip-router.org/pipermail/sr-users/2012-August/074479.html

The content has the spam message, but that happens because there are two 
spamassassin checks, one done at iptel.org and one done by 
lists.sip-router.org (hosted by kamailio.org). For some reason, 
spamassassin on kamailio.org does not detects it as spam anymore, 
setting X-Spam-Level to empty.

Is anyone familiar with such setup of chaining spamassassin? Is there a 
setting we miss in spamassasin to tell to check also X-Spam-Level of 
incoming message and trust it, eventually when coming from a list of 
preset IP addresses.

Thanks,
Daniel
