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....
