Postfix is the default Mail Transfer Agent (MTA) for most Linux distributions including Suse. Postfix is written to be compatible with Sendmail. It supports Sendmail conventions like /etc/aliases and .forward files, so we can easily put Postfix on a system without breaking any applications that depend on Sendmail. The Sendmail executable program, sendmail, is replaced with a Postfix version that supports nearly all of the same command-line arguments but runs in conjunction with the Postfix system. Postfix really shines as an MTA because of its rock-solid reliability.

Postfix Overview - Introduction

Postfix is the freeware project that I started during my sabattical year in the USA while visiting IBM T.J. Watson Research. I am grateful to IBM for the opportunity to write this software and for their permission to give it away.

Postfix is my attempt to provide an alternative to the widely-used Sendmail program. Postfix attempts to be fast, easy to administer, and hopefully secure, while at the same time being sendmail compatible enough to not upset your users.

The original plan was to release this software under a different name, VMailer. With the release in sight, IBM's lawyers discovered that VMailer was too similar to an existing trade mark. So, the program will go through its life as Postfix instead.

Postfix is a direct competitor to the qmail software by Dan Bernstein. That's competitor, not enemy. I'm sure that friendly competition will help to improve both programs.

[Dec 24, 2009] How To Relay Email On A Postfix Server HowtoForge - Linux Howtos and Tutorials

For two small businesses I set up a debian lenny installation on their "home" dsl connection. The problem is that they have dynamic ip addresses and most mailservers will not accept incoming mail from a server on a dynamic ip address. The solution is rather simple. Set up postfix in a way that it will relay the outgoing email through the actual ISP. In this short howto I'll show you how to do that.
