Re: SPAM: Bayesian filtering

I almost never get spam. I have discovered that most spammers send mass
mailings with the recipient list suppressed. (They don't want anyone
else harvesting e-mail address from them without permission. How
ironic!) This simple fact distinguishes virtually all mass mailings
from individual mailings to my address. This makes it easy to make a
simple rule so I get individual mailings to me while I block all mass
mailings. The only exception rules that need to be created are when I
want a mass mailing (as when I sign up for a mailing list). By default,
these filters do what I want. I get 500+ spams per week. In the two
years of doing this, I have never rejected a real message, and very
rarely have gotten a spam into my primary incoming folder.

On MacOS X, my mail filter rules are:
- If "body of message" contains "Harvey" or "Newstrom" then move to
"about Newstrom" folder
- If "To: or CC:" contains "extropians" then move to "Extropians List"
folder
- (other rules for other e-mail lists...)
- If "To:" or "CC:" contains "newstrom.com" then move to "for Newstrom"
folder.
- otherwise move to "Mass Mailing" folder
