Spamassassin works quite well for me.  Per the documentation, I put the
following in ~/.procmailrc:

:0fw
| spamassassin -P

:0e
{
    EXITCODE=$?
}

:0:
* ^X-Spam-Status: Yes
caughtspam

The last recipe writes all the spam to a file I inspect before deleting
the messages, as sometimes non-spam gets flagged.  You can whitelist
specific addresses and/or change the weighting to tailor the filters to
your own needs.

I am running testing/sarge.  If you don't keep spamassassin updated,
you will find that more stuff starts slipping through.  I typically
find that much less than 1 percent of the spam gets through, however.
