The spambayes project doesn't (despite its name <wink>) do Bayesian
classification, or N-way classification.  A good paper on a good system that
does both is Jason Rennie's

    "ifile: An Application of Machine Learning to E-Mail Filtering"

The paper summarizes the classic Bayesian classification approach.  Do learn
how to use citeseer:  it's a great way to find papers on tech subjects!  The
citeseer record for the paper above is:
