About:
Postfix is an 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.

Release focus: Minor bugfixes

Changes:
The postdrop mail submission command could die with SIGHUP and abort mail submission. The MySQL client aborted with complaints about multiple attempts to register the same lookup table. As a workaround for aggressive SMTP command pipelining clients, the SMTP server now allows clients to overshoot the server recipient limit without triggering the server hard error limit. The LMTP client attempted to reuse a connection after timeout, causing protocol synchronization errors. The trivial-rewrite server could core dump after temporary table lookup failure.

[»] Some thoughts on Postfix
by Crippler - Feb 17th 2003 19:10:29

Let me get the negatives out of the way FIRST.

1) License sucks. Why couldn't IBM have released this under one of the big licenses like BSD or GPL? If this had been BSD licensed, we'd probably see it overtake Sendmail by now (even in Linux distros).
2) Back end database support. It's been a bit lacking. My understanding from the mailing list archives is that the maintainers are putting security, performance & stability over features. This is a noble cause which I am hesitant to criticize. But as a Postfix user I sometimes feel as if it would better serve me with more flexible back end options.

Stuff I like:
1) Easy to set up. It has a big config file, but it is in plain english and well commented. You don't have to read a book before setting it up.
2) Drop-in replacement for Sendmail. It replaces the command-line sendmail utilities and everything.
3) Secure. You hardly ever hear anything about Postfix vulnerabilities on Bugtraq.
4) Fast. I've set up some large mailing list servers on Postfix and it just rrrrrips.

Overall I give it an 8 out of 10. The license bugs me but there is not a lot that can be done about that now, at least not by the Postfix maintainers (but IBM could retroactively re-release their code under BSD or GPL and Postfix could opt to relicense their copious additions). There isn't a lot of push for this so I won't hold my breath.

Forget sendmail, install Postfix - real-drop-in-replacement, nice configruation, fast, reliable - perfect

I've been using it since the Postfix 19990317 release and I've never had any trouble with it. Drop in replacement for sendmail that doesn't require aspirin to configure. And performance is *great*, too.

[»] I'm impressed
by Chris Horry - Jan 5th 2000 09:25:44

And that takes a lot! I tried Postfix after hearing good reports and first impressions are that it's a superb mail server, I managed to make a complete mirror image of my existing sendmail setup in a couple of hours from first downloading it. Looking forward to seeing how well it performs when I start hammering it :-) Thanks!

[»] postfix is very good
by karellen - Dec 26th 1999 02:58:43

Ok, with the world writable directory fixed postfix became a very good MTA. Eventually I got rid of qmail and installed postfix after several people told me it's fast and reliable. It even supports MySQL database lookups now and other advanced stuff and the IBM license it's distributed under is surprisingly liberal. Postfix has also made it into Debian/Potato. Thanx again Wietse.

[»] World writable maildrop issue
by Edgard Castro - Mar 7th 1999 19:02:15

As of December 30, 1998, Postfix offers a choice between a
world-writable maildrop directory and a protected one.
