For effectiveness, time, and simplicity I found that spamassassin met 
all of my needs.  To be effective I had to lower the score threshold 
down to 2.8 and create a whitelist to not dump my parents (WHO INSIST ON 
TYPING IN ALL CAPS!!!).  But with six lines of procmail, it's all setup. 
 Anything with spam-status flag of yes gets dumped in an out of the way 
folder.  I think it's nice because I don't have to teach it what spam 
is.  I get the same junk as everyone else, and as such, the rules 
already exist.
