That is a good choice, but you ought to do your own spam filtering on
your own computer. If you're writing procmail rules (like Bill is),
you should have the procmail rules run a well-trained spamassassin
yourself.

My mail setup involves having fetchmail grab my mail from ucdavis.edu
every 5 minutes (by cron), and when it does it strips any spamassassin
report that might already be included in the message, then it filters
off a few email lists that I trust, then it runs the remainder through
SpamAssassin, before continuing to filter.
