We see a lot of these. Almost all of them are stopped by a combination
of Bayes and the SARE Stock Scam rules. (Our Bayes database is
rather large, containing some 390,000 e-mails and around 4 million
words and word pairs...)
Aditionally, I use a feature of our filtering software that holds any
e-mails containing images in the trap, unless the sender is whitelisted.

David.
