Most blacklist checks are really better done server-side, at the time
of mail delivery. At that time, you have access to much more
reliable information about where the email is coming from (after that
time, you really only have whatever the spammer put in the email and
a few headers added along the way).
However, doing some DNS-based checks (e.g. SURBL) does appear to
help. I have code that does various lookups, which at some point
I'll get around to adding as an experimental option to the tokenizer
(possibly only when messages are unsure, like the 'slurping' options,
since these are pretty time-consuming). Some of the work on these
was done in work-time, so I'll have to clear with that employer that
it's ok to add it, but it should be ok.

If you send us the clues (SpamBayes->Show spam clues for this
message) then we may be able to offer advice.
Please always include the list (spambayes at python.org) in your replies
