false negatives

I'm seeing a bit of spam slipping through that I'd have thought would get
caught.  It looks pretty spammy, and here's the SpamCheck results:

X-CBJ-MailScanner-SpamCheck: not spam, SpamAssassin (score=2.309, required
        BAYES_00 -4.90, DRUGS_ERECTILE 1.00, DRUGS_ERECTILE_OBFU 1.50,
        HTML_50_60 0.10, HTML_FONT_BIG 0.27, HTML_MESSAGE 0.10,

This is just one example, I also see the odd mortgage pitch, or a 419 scam,
etc. every now and then.  Strange thing is, sometimes I'll see a spam
message slipping through and an identical (but different recipient) one
getting caught.  Didn't think to compare the headers at the time though.

On about all the stuff that slips throuhg I see the first test, BAYES_00
-4.90.  Would this indicate that I'm suffering from a case of bayes
poisoning?  Should I dump the bayes database and start over using the
starter kit on Fortress' site, or are there other, better options?
