About Symantec Message Filter deployment on the Client and the Server

Symantec Message Filter software can be deployed in a variety of computing environments, from single computer setups to distributed client-server configurations. In each case, the Symantec Message Filter Client integration communicates with the MTA by using standard libraries. As messages flow through the mail server, the Client calls the Server. The Server checks individual messages against antispam filters, antivirus definitions, and other filters that you configure. Based on the verdict that the Server returns and the Server and the configuration options that you configure, the mail may be handled differently.

Scenario

Advantages

Notes

Single MTA and Symantec Message Filter Server on one computer

Saves the hardware cost because the MTA and the Server reside on the same computer.

MTAs tend to be inbound and outbound. By comparison, the Server is CPU-intensive, so the two programs use different software resources. However, if the Server saves spam to disk or performs virus processing, it is inbound and outbound.

The MTA must not use a large quantity of CPU cycles.

Single MTA and Symantec Message Filter Server on separate computers

Advantages of the MTA and the Server installation on separate computers are as follows:

  • Requires minimal or no change to an MTA server

  • Provides scalability

  • As mail throughput increases, you can add processors or memory to the Server to suit your needs.

  • Provides flexibility

    The MTA server and the Server can run on separate platforms.

This configuration is an adequate solution for most small to medium-sized enterprises.

Multiple MTAs and Symantec Message Filter Servers

Advantages of multiple MTA and the Server installations are as follows:

  • Provides maximum scalability

  • Offers full failover and redundancy

  • Provides built in round robin load balancing

  • Allows for easy implementation of a virtual IP (VIP), which enables scalable load balancing

  • Provides flexibility since the MTA server and the Server can run on separate platforms

Most of this information is applicable to all MTAs. Consult your Symantec representative to determine which scenario best meets your needs.

If your environment has a high volume of traffic, consider to use Symantec Traffic Shaper. This network device allocates reduced bandwidth to MTAs that deliver spam. The load on your MTAs is reduced without introducing false positive risks. For more information about Symantec Traffic Shaper, contact your Symantec sales representative.
