I used to until I designed my own spam filter -- as I'm co-owner for an
ISP, I needed to make sure there were as few false positives as possible.
The only downside is you need to be:

1) the admin of your mailserver (it's a server-side solution)
2) running qmail (the best MTA on the planet...) & Perl
3) running PostgreSQL [not absolutely necessary, but works a lot better]
4) some time to get the automagic filters rolling...

I went from 50-150 spams/day down to 4-9 (6 being about average) - I wrote
programs to take all the doublebounce messages, extract the relevant IP
addresses, put 'em in a postgres database, then run reports on the data,
and block those IP addresses automagically. The load on our mailserver went
from a .69 average to a .27 once it was up & rolling...
