Spam Filtering
Our scan engine uses a layered approach that maximizes kill rates and minimizes false positives. We do not use any ‘scoring’ or rating systems for identifying spam – those systems are plagued by high false positive rates and are really only ‘guessing’ at spam. And when it comes to protecting your message, guessing isn’t good enough.
The core layer for threat identification are the spam signature files. Those spam signatures are created and managed by human spam editors who look at spam 24x7x365, and we release new spam updates every 5 minutes to ensure that our customers have the latest rule sets to defeat spam attacks as they happen.
Because our signatures are designed around actual identified spam, the system isn’t guessing at identifying incoming email, thus our false positives are the lowest in the industry. Period.
How It Works
NexTek Hosted Anti-Spam works by routing your email (MX records) to our network data centers where we clean your email and then pass it on to your email server. It’s really simple and easy to setup, and no hardware or software is needed or required to setup.
