Nice one. I've also added the following with good success:

# crank up bayes scores
score BAYES_60 0 0 2.002 1.160
score BAYES_70 0 0 2.900 2.300
score BAYES_80 0 0 5.000 3.200
score BAYES_90 0 0 5.600 4.100
score BAYES_99 0 0 6.000 4.300

# improve some scores
score USER_AGENT_MOZILLA_UA -4.0 -3.5 -2.5 -2.0
score MSGID_GOOD_EXCHANGE -4.0 -3.5 -2.5 -2.0
score USER_AGENT_VM -4.0 -3.5 -2.5 -2.0
score UPPERCASE_75_100 1.0 1.0 0.8 0.8
score VIAGRA 1.249 2.162 0.822 1.267
score MIME_HTML_ONLY 0.600
score IN_REP_TO -2.300 -2.301 -0.600 -1.600
score EMAIL_ATTRIBUTION -3.600 -3.500 -3.500 -3.500
score REFERENCES -4.600 -4.600 -3.500 -3.500

The most important thing was to lower the negative scores for the
USER_AGENT hits, as spammers got way to good at forging these. Same goes
for REFERENCES and IN_REP_TO.

Cheerio,

Thomas
