Why MailFoundry Anti-Spam?

Trusted : MailFoundry's anti-spam engine, "MessageIQ" was designed from the ground up to protect your message while taking care of spam, viruses and other email threats.

Proven : For over four years MailFoundry has been eliminating spam from email for over 2 million mailboxes world-wide.

Effective : MailFoundry is very effective at killing spam, but the real benefit is in our false positive rates. We lead the industry with a false positive rate of less than 1 in 1 million. Some customers have seen only one false positive in over four years of service.

Easy to Use : MailFoundry is a 'hands off' system meaning that administrators and end users are not spending time managing the system for rule creation, etc.

How it works?

MailFoundry's MessageIQ 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.
