Internet Exchange Messaging Server
Channel Action Matrix FAQ

Overview
For each module in the Preprocessor Unit, the Internet Exchange Messaging Server associates a corresponding configuration object, called the Channel Action Matrix.  With the Channel Action Matrix, system administrators have a flexible tool for configuring which modules in the Preprocessor Unit should be run for a particular message, based upon the message flow or routing within the MTA.  For example, to minimize delay in message delivery, the system administrator may not want to run the Anti-virus module for messages coming from a cc:Mail user and destined to another cc:Mail user or Lotus Notes user within the system.  Or he may want to run the Anti-virus module only for messages coming from the Internet and not for messages bound for the Internet.  These options are easily and fully configured in the appropriate module's Channel Action Matrix.
