How it Works
MailGuardian is an online email filtering service that scans your email for spam and viruses removing any harmful emails and forwarding good emails onto your mail server without any delay in the delivery process.
The MailGuardian 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 new spam updates are released every 5 minutes to ensure that 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.
MailGuardian 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 we are available to assist you if needed.
Works With Your Domain Name
The only requirement for MailGuardian is that you have your own domain name. This service does not work with ISP email accounts like Yahoo, AOL, Tiscali etc.
