        <h3>Protector and TLS Enabled Postfix for Explicit MTA </h3>
        The protector component in Websense Data Security v7.5.x includes a Postfix release compiled with Transport Layer Security (TLS) support. Configuring Postfix allows you to enable TLS support. Although TLS is not officially supported, Postfix is available to allow for individual customer configurations.
        <p>This document provides a simple example TLS configuration for use as a test case and as a reference for future deployments. The sample configuration is stored on the protector in /etc/postfix/main.cf. </p>
