If you use the latest version of Mozilla the mail client includes a 
Bayesian spam filter.  I've only been using it for about a week, but 
already it catches over 95% of the spam I receive, and there was only 
one false positive on the day I first started using it.  For instance, 
the filter marked the first message in this thread as junk, but was 
smart enough to realize that the replies were not junk.

Of course, this only helps if you subscribe to ruby-talk rather than 
read the newsgroup.
