This is probably a more global solution than what most people 
want, but my ISP recently developed MailArmory, the most kick-
butt spam filter I have seen yet.  

They run it and keep the spam and virus filters up-to-date, so 
there's virtually no overhead for you.  You have the option of 
tagging spam mail and still downloading it to your PC, or having 
them hold the questionable mail so you never even have to 
download it.  You can review the tagged messages on their servers 
if you want.  I downloaded them for a while to verify MailArmory 
was tagging spam correctly, and to see who I needed to add to my 
"Accept list," but I've been letting MailArmory intercept and 
discard my spam for months now.

I get a lot of email, and a *lot* of spam.  So far this month 
I've received 2744 messages, of which 1820 (66.3%) were spam!  
This is the 16th of the month, so I'm receiving over 110 spam 
messages **PER DAY**.  And it's accelerating at a frightening 
rate -- it's increased almost 50% in the last MONTH.

Thanks to MailArmory, only 148 of those spams made it to my 
system.  MailArmory catches almost 93% of the spam.  They would 
do even better than that, except for an odd artifact of how mail 
is routed within their servers.  (A few spammers have somehow 
harvested a semi-bogus address that goes directly to the ISP's 
email router and bypasses MailArmory.  I don't think that would 
apply to customers of other ISPs.)  I can catch those cases with 
one additional simple rule in my emailer, which knocks out over 
2/3 of the 7% that MailArmory misses.  The end result is that I 
see only about **3** spam messages per day.  And MailArmory also 
intercepts viruses!

They market MailArmory for other domains.  It's less than $10/mo 
per 100 mailboxes in your domain -- and WELL worth it.  Maybe you 
could talk your ISP into providing it for their users.  And I 
think they're working on getting it to work for individual users, 
too.  You can get more info at http://www.MailArmory.com.

No affiliation except as a *very* happy user.
