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.
