About Postfix

Postfix is 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. Postfix attempts to be fast, easy to administer, and secure. The outside has a definite Sendmail-ish flavor, but the inside is completely different.
