Postfix Profile and History

All programmers are optimists -- Frederick P. Brooks, Jr. First of all, thank you for your interest in the Postfix project. What is Postfix? It 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 defin ite Sendmail-ish flavor, but the inside is completely different. This website has information about the Postfix source code distribution. Built from source code, Postfix can run on UNIX-like systems including AIX, BSD, HP-UX, Linux, MacOS X, Solaris, and more. Postfix is also distributed as ready-to-run code by operating system vendors, appliance vendors, and other providers. Their versions may have small differences with the software that is described on this website.
