I've never tried the free version. I use the subscription version. It costs $39.95 a year and works like a charm. It filters almost all the spam except when new spamming techniques are developed, then it takes the developers a week or two to update the software and it's quiet again. The only false positives are the occasional newsletter (such as weekly airline specials). I scan through the spam headers quickly and train SpamNet to always accept mail from these senders. It has never once blocked a personal message.
