This is a good guide and has a basic description of how a bayes filter works.
http://www.paulgraham.com/antispam.html

Also have a look at

http://en.wikipedia.org/wiki/Bayesian_spam_filtering

The bayes algorithm is only one part of a spam system though. You also need to consider what to do about expiring content from the bayes database.
You can also create your own bayes tokens for other characteristics of the message such as the number of hours ahead or behind actual time the email was sent. A lot of spam is sent with a sent date weeks or more in the past so that type of additional check can be very good. Its that sort of thing which differentiates one bayes based antispam tool from another.

No sorry I dont know of any delphi code sites.

There is http://www.hotscripts.com/Detailed/58242.html written in php which is an easy to understand language. You could look at that and convert it to delphi.
