Filtering html was effective for quite a while, but they seem to have 
adapted.  Most of the spam that isn't being caught now is text only 
with reasonable headers (with valid, even forged From:).  Lately the 
regexps I use don't even catch the similar-but-different variations 
on the common scam mails.  Such a pain....
