*** Please note that mxGuard is no longer offered by the manufacturer. This doc is here for historical reference. ***
mxGuard intercepts each message passing through the mail server and runs a range of tests to determine if the message is "spam". Each of the tests are configured with a numeric value. The results of these tests are tallied up providing a spam score. This score is compared to user-defined thresholds. Message headers are then added to each message so that standard Imail rules can be used to process the message as desired. mxGuard includes built-in hooks to seamlessly integrate Message Sniffer.
The Message Sniffer Installer handles the setup of mxGuard/Imail with SNF.
