Eudora 6.0b31 and spam filtering
Did I mention that Eudora 6.0b31 was out?
This review of Eudora 6.0b31 points to a great article by Paul Graham about the Bayesian spam filter used in Eudora. The article is one year old, but it's still very interesting. Furthermore, I can confirm that Eudora's spam filter is incredibly efficient!
And I agree with Qualcomm's recent decision to make it available only to users of the paid version. It's too great to give it for free!
