Postfix is a fast, easy to administer, and secure Wietse Venema’s mail server that started life at IBM research as an alternative to the widely-used Sendmail program. Now at Google, Wietse continues to support Postfix. Built from a source code, Postfix can run on systems such as UNIX, AIX, BSD, HP-UX, Linux, MacOS X, and Solaris.
Postfix is also distributed as ready-to-run code by operating system vendors, appliance vendors, and other providers.
