So I'm curious.... what spam filtering tools are people using? I've been playing with them a bit lately.
I've been using an anti-virus package on my mail server at work called RAV. Written in Romania, it was dirt cheap and did a fabulous job of smacking down viruses before they get to my users' computers. When they added on spam filtering in a later upgrade, I jumped on it. So far it has worked OK.
On my home computer, I have tried out Spamnix, which is an implementation of
spamassassin as a Eudora for Windows plugin. It works pretty well, but with my mail at least missed a fair amount. It became onerous to be throwing out the missed spam into the re-filtering. Also, the filtering was quite slow (admittedly I have an older computer).
I'm currently trying out POPFile. POPFile is an implementation of
Bayesian filtering that runs on Windows and sits as a proxy between your POP3 client (Eudora, Outlook, Mozilla, etc. etc.) and the server. The whole Bayesian concept is very simple and elegant... and it's damned effective!! I installed POPFile on Saturday before I had downloaded any mail, and then downloaded whatever mail I had and sorted it. Since that time it has correctly deduced which of 260 emails were spam and which were not, with 1 error.
So, what have you tried? what did you like, or not like?
