Spam is unsolicited (generally commercial) "junk" email. GTI uses a multi-tiered approach to filtering spam. All of GTI's mail servers use RBLs (DNS-based Realtime Black Lists) and the latest mail server software to stay current with popular spam prevention methods. We also run heuristic scanners to scan all mail that passes the RBL and initial built-in tests. These heuristic filters are your second line of defense, providing an additional, more "intelligent" layer of filtering, able to evaluate each message's contents to determine whether a message is spam or ham based on complex rules and algorithms.

For customers who need still an additional and stronger layer of filtering, GTI offers EAV (Email AntiVirus). This service is also available to non-GTI customers--your mail does not need to be hosted with us to take advantage of EAV. This is ideal if you host your own mail in-house (e.g. on an internal Exchange server) and need stronger spam filtering with the addition of antivirus scanning.

Our EAV server runs Trend Micro's InterScan Messaging Security Suite. It is implemented by changing your domain's MX record to eav.gti.net. MXes control your domain's mail routing in the global Internet, thus EAV is effective by forcing ALL inbound mail to pass through its scanning modules first. EAV then delivers the "clean" mail to your server's IP address
