Configuring Trusted Layer Security

Sendmail includes support for enhanced security: Secure Socket Layer (SSL) and Transport Layer Security (TLS). SSL and now TLS (successor to SSL) are used to establish a trusted connection. Sendmail's usage of TLS is not end-to-end encryption. Certificates in X.509 form are used to form this trusted connection.

To use TLS, sendmail needs a source of random information. This Internet Express release includes both Tru64 UNIX Version 5.1A and 5.1B sendmail binaries to allow access of the appropriate random number generators. In version 5.1B, the Sendmail binary uses the native /dev/random device, while the Tru64 UNIX Version 5.1A operating system version includes support for egd.
