I'm using several checks, including bogofilter and spamassassin. I'm 
finding the combination particularly powerful, and I've recently started 
incorporating bogofilter (and other bayes) scores into spamassassin 
rules that do header checks. Rather than count on one or the other being 
accurate (both ways -- we get a lot of wanted "spammy" mail here), I set 
up a spamassassin rule to act on the bogofilter (and other) headers. In 
short, this lets me use whitelist and some of the other spamassassin 
niceties, with the bloodhound strengths of bogofilter. It also gives me 
a consistent report format for reviewing messages that are flagged as spam.
