Subject says it all. The Junk Mail filter just isn't good enough anymore.

May I recommend what we're doing now at work.. We have exchange 2k3 and 2k7 and we poing our MX record to nettica (dns hosting site, etc) and they have a sweet white/black list system. We decided to do this since we were getting bombarded with directory harvesting (20000 emails a day!). Now we just have a text file with all email accounts that are allowed to pass nettica's filter and when it does, it has to pass GFI mail essentials, it checks for just about everything. Messages are then marked as spam and a rule can be created in outlook to put anything with the word spam in the junk email folder. I get 1 or 2 a week.. Life is good.

Edit: woops, didn't see the free there..
If you're looking for free, what you can do is send all your mail to a linux machine with spam assassin.. I heard it works ok...
