Guide Review - SAproxy 2.5 - Spam Filter
SpamAssassin has a sophisticated set of heuristic spam detection methods, effective Bayesian filtering and a good record of spotting junk mail. What it did not have was easy of use on Windows. SAproxy changes that.
Easy to set up and install, SAproxy lets you profit from highly effective spam filtering transparently and comfortably. SpamAssassin has one major shortcoming: training the Bayesian filter is a bit cumbersome.
Unfortunately, SAproxy doesn't improve that. Not even Bloomba, an email client from the makers of SAproxy that otherwise integrates it well, lets you teach SAproxy about a false positive easily. You can import mail from several email clients to train SAproxy's Bayesian filter in bulk, though. It's also a pity SAproxy only works with POP accounts.
These imperfections notwithstanding, SAproxy is an effective anti-spam companion.
