EMP - Enterprise Anti spam Filter By J.A. Korsmeyer, Inc.

Extensible Messaging Platform is a SPAM filtering firewall server application. Protects Exchange Server, Domino, GroupWise or any SMTP mail server from Internet SPAM, e-mail-borne viruses (including dangerous auto-launch viruses) and other objectionable content. Filters mail using complex contextual signatures (not simple keyword lists). The use of contextual signatures results in high success and extremely low false-positive rates. Additional features include automatic XML extraction/database insertion, optional POP3 retrieval, comprehensive user-definable contextual filtering, content-based message routing and developer API. License includes JAK filter capsule so it's armed to block SPAM "right out of the box". Installs as Windows Service or UNIX server.

For high message volume deployments, as well as architectures requiring better transaction isolation, concurrency, scalability and compatibility with third-party SQL client tools; EMP supports MySQL as a high-performance alternative to its embedded SQL database.
