Yes. I've done a bayesian spam filter based on Exim's perl support.
I wrote a small article about my solution here:
http://www.tapsellferrier.co.uk/nics-articles/spamhandle.html
That's a bit out of date (I'll rewrite it soon) because spamhandle.pl
now works with DBMs instead of text databases. That makes it very
quick and scalable. My current spam ratings database is 66Mb big but
all my mail is scanned by a single machine with an AMD K5 and 350Mb of
RAM (in other words, not very powerfull).
It's quite effective as a spam filter but I also filter out stuff with
headers from other spam software.
