Remember that some unbelievable number of infected Windows

the main source of spam and it would just be too much trouble for the
spammer to try every address twice after a 15 minute interval.
Oh come on! It costs the spammer NOTHING to make that adjustment
to his bot net. Its someone else's bandwidth, and someone else's
cpu cycles.
They are reading this list and planning the changes already.
Of course! Spam and Spamassassin is the ultimate cops & robbers! I'm
sure the best spammers continually update the rules and run their own
tests against them to develop new mails which get through. Despite
everyone's best efforts we are fighting a losing battle with a
solution that does not tackle the botnet problem at source but for
that to happen things might have to get a whole lot worst! :-/
