Internet Exchange Messaging Server
Preprocessor FAQ

Overview
The Internet Exchange Messaging Server Preprocessor (both Enterprise and Workgroup versions) is an integrated subsystem of the MTA with a highly scalable architecture.  Each of the unit's programs is a plug-in module that can be run on separate machines, ensuring efficient utilization of computing resources and maximum throughput.  This capability also guarantees that the system can easily be scaled to cope with the changes in the messaging needs of an organization.  In addition, the Preprocessor Unit incorporates an open API that permits the development of third-party or custom processing modules.  Communication between the different Preprocessor Unit's modules is carried out via Remote Procedure Calls (RPC's) over TCP/IP.

The Preprocess is made up of the following standard components:

• Anti-Spam Module
