Another thing this person can do is run SpamAssassin on his own
machine with the configuration under his control. One key to the
whole thing is fetchmail. With that you can drag down your own
mail, feed it to a tool such as procmail, and have procmail run
SpamAssassin for you on your own machine. That means you can put
in all the rules and training you want.

(And since SpamAssassin is a perl based tool there are even ways
to run it on Windows machines.)
