Hi Techie,
Thanks for the recommendations. However, Spamihilator is the one I'm sticking with. Over the years, I've tried just about every free spam checker. The three I recommend are Spamihilator, SpamPal, and G-Lock SpamCombat.
but Spamihilator is very over-rated and takes a lot of careful configuration with Avast.
Actually, Spamihilator is easy to configure with Avast. No worse than any other spam checker.
If I were to use an inline filter type spam checker, I would use G-Lock SpamCombat which I have tried and like a lot. It is free for any amount of accounts, whereas Mail Washer is not. I have tried K-9, but not particularly fond of it.
Inline checkers bring emails directly to your computer, but proxy spam checkers check the emails and delete spam before they are downloaded. I prefer this type of checking. Also, no viruses or worms are downloaded either. Avast kills them when Spamihilator checks them, so no download occurs.
After about a month, Spamihilator is pretty accurate also. Probably around 98% and it improves every day. The program keeps getting better as Michel (the developer) updates it.
