I've added three procmail rules in the last few days to combat the deluge of these (and other) spams. I figure that these are all passing fads and aren't worth writing SA rules. YMMV, of course, but in my case, the procmail method works best.

I've cut the volume of spam that makes it to my inbox and spam folder in half - the rest goes directly into the 'learn' directory, where a cron job runs once an hour to add them to bayes.
