"We recently moved to SpamTitan from Mimecast. The price point was better, and the feature parity was close enough to make it an attractive move. I love the fact that you can use dynamic recipient filtering and not have to do a ton of configuration on your mail server to get it working.
I feel like they have many different features for spam filtering that allow the good stuff in, keep the bad stuff out, and empower users to unjunk items on their own if needed."
