Mail spam filter port on Linux?

[mcs37]

I've been thoroughly impressed with Apple's Mail spam filter that uses latent semantic indexing, a technique I first learned for an effective web indexing system. I am curious if anyone knows if there is a similar system available for e-mail servers or clients elsewhere in the computer world, specifically Linux. Right now my Linux server gets about 90% of the spam coming in using SpamAssassin, while Mail I have noticed gets near 98% of mine.

Does anyone know if there is such a port available on Linux? Perhaps for the Pine e-mail client? I think I will ultimately combine the two (http://www.benhammersley.com/undocumented_features/combining_mailapp_and_spamassassins_bayesian_learning_ability.html) (right now I'm not using SpamAssassin on the account that my Mac reads) for maximum effectiveness, but I was curious if I could simply use Mac's filter from the beginning.

SpamAssassin has bayesian filtering, the same as Apple's Mail.app.

I was under the impression that latent semantic indexing != bayesian filtering, which is more of a self-learning system. Either way, Apple's filter is a LOT more effective than my SpamAssassin.

As of SpamAssassin 2.63 (the latest version I've used), it's still bayesian. I'm pretty sure that Mail.app uses a bayes spam filtering model as well.
