If you're looking for a way to get rid of picture spam, try the SARE

Simply add
these rules to your setup using sa-update & the openprotect
channel (see
http://saupdates.openprotect.com/). It doesn't take the cpu cost
of the
fuzzyocr plugin.
Unfortunately they are not quite good enough to get rid the new
image spam. :-(
The SARE rules in combination with a tuned Bayes database get
most of these, but a fair few still slip through.
Yep, I'm so used to bayes, I simply assumed OP would be using it.
Silly of me.
OTH, I just looked at some of my recent image spam and when I
substract the bayes score from the final score, most of it would
still be tagged as spam (I use a threshold of 5). I'm also getting
fluctuating bayes scores; to prevent bayes poisoning, I even feed
them to sa-learn with --forget.
I can imagine however that if you're an isp like service, you'd leave
out bayes and have a fairly high threshold to prevent false
positives, you'd have to increase the scores on the image spam
related SARE rules. they don't seem to hit ham so I'd think that
would be safe.
