"After using a cloud-based barracuda solution we tried out this one in an evaluation version. The performance of the virtual Hyper-V box is amazing! has greylisting/Dkim and TLS, and 99,99% of the spam is being filtered. It does a better job than the 'cuda's!
After a week on trial, we decided to buy a 3-year license. One of the best easy to use products I have seen in a long time."
