Spam filtering in Apple Mail

I have been noticing that Apple Mail has been marking valid mail as spam pretty often, and it doesn't seem to be improving when I train with these mistaken spam messages. 

I had been thinking that Apple's Mail was using bayesian analysis to determine the spam messages.  But I just found out that Mail uses Latent Semantics analysis for spam filtering.  This post has a great description and comparison of Latent Semantics and Bayesian Net.
