The Message Processing Platform (MPP), by RAE Internet, is an application framework designed specifically for deploying email - scanning services on Unix mail servers. The MPP provides a central point for configuration and management of virus, spam and content filtering services, while offering the flexibility to deploy the mail server or scan engine that best fits your business and security needs.

The MPP is built on a modular and fault-tolerant architecture which isolates email server to scanner communications, enabling features such as scanner serialization, in-service scanner insertion and removal, and non-disruptive configuration changes.
