I use Mailwasher as well. It has an added bonus that it "bounces" e-mail so it looks as if your isp is returning mail because your address does does not exist.
IMHO the most reliable way to avoid spam is to change e-mail address. There is a slight inconvenience from having to advise legitimate customers etc, but at 200spams/day I wouldn't hesitate. Then make sure your new e-mail address never appears on web pages, bulletin boards etc. Use a "dummy" hotmail address for sites that require e-mail registration; for company web pages that do need an email address, use one of the javascript or other mechanisms that assemble a visible e-mail address without actually including it in the page to be found by robots.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
