Fight against SPAM is war without end. But in many cases (my mail box
fills with this sort of mail very fast - more than 20 messages/day,
while "normal" messages around 100-500/day) spammers algorythm very
trivial: scanned open relays and dialup/DSL machines, many of those
mail comes with mail_from on yahoo (callback to yahoo doesn't help).
Multihopped SPAM very rare.
