postfix: Postfix aims to be an alternative to the widely-used sendmail
postfix: program.
postfix: Although IBM supported the Postfix development, it abstains from
postfix: control over its evolution. The goal is to have Postfix installed
postfix: on as many systems as possible. To this end, the software is given
postfix: away with no strings attached to it, so that it can evolve with
postfix: input from and under control by its users. 
postfix: This version is compiled with TLS and SASL auth support.
