I created custom spamassassin rules which matched the names of our
products in the body of messages, this got rid of almost all of the
false positives from our clients.

Also throwing DCC, Razor, Pyzor and a handful of RBL's into the
spamassassin mix helps to raise the average spam score, meaning you can
set your threshold a little higher and avoid some of the marginal false
positives.

Keep an eye on the spamassassin rules the false positives match and
tweak their scores if necessary

Finally consider only blocking high scoring spam and just tagging (or
tagging and stripping) low scoring spam, then lower your high score to
be just above the highest false positives you are getting.  That way you
get rid of most spam, but don't lose real mail.
