It's certainly the intent of the project to interoperate with any FLOSS MTA.

It should be rather trivial to integrate MM3 with any MTA that supports LMTP delivery (currently the only supported method) which includes Postfix and Exim, and should include Sendmail afaik. For the most part, not much needs to be done on the Mailman side, so it's mostly getting your MTA configured correctly. Contributions welcome of course!

Thanks to all who replied. Since I've used sendmail and have limited experience with it, I decided to go with that. Less variables in the mix! :)

Anyway, proceeded with the install and got to make install, which failed with Permission denied for the mkdir commands. I'm running from a non-root userid who has a membership in the mailman group. The directory /usr/local/mailman has rws privs for the mailman group (but is owned by root). Do I need to do a sudo make install or am I missing some type of privilege setting?

sendmail is still widely used, and if I were you, I'd just stick with what works unless you have you a particular need that sendmail wasn't filling.

+1 with caveat:

I have it working fine. I recently replaced a very old implementation of sendmail and Mailman on Solaris with a new one on CentOS 6. When I did so, I used the POSTFIX_ALIAS_CMD mechanism to automatically process the aliases. See: https://mail.python.org/pipermail/mailman-users/2004-June/037518.html

In mm_cfg.py: MTA='Postfix' POSTFIX_ALIAS_CMD = '/usr/bin/sudo /etc/mail/import-mailman-aliases' /etc/mail/import-mailman-aliases contains: #! /bin/sh /bin/cp /etc/mailman/aliases /etc/mail/mailman.aliases /usr/bin/newaliases In /etc/sudoers.d/mailman: Cmnd_Alias IMPORT_MAILMAN_ALIASES = /etc/mail/import-mailman-aliases apache ALL= NOPASSWD: IMPORT_MAILMAN_ALIASES mailman ALL= NOPASSWD: IMPORT_MAILMAN_ALIASES Defaults!IMPORT_MAILMAN_ALIASES !requiretty In the sendmail.mc file I changed: define(ALIAS_FILE', /etc/aliases')dnl to: define(ALIAS_FILE', /etc/aliases,/etc/mail/mailman.aliases')dnl so that the Mailman aliases would be in a separate file.

Warning: You need to have Mailman 2.1.15 or better (or patch it). See this bug: https://bugs.launchpad.net/mailman/+bug/266408. A fix is here: http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/1291 (Thanks to Mark Sapiro)

I stayed with sendmail because I am using LDAP for aliases and routing and I did not want to figure out how to do it with Postfix. My one exposure to Postfix was a disaster trying to fix the email services on our marketing department's web server at a hosting provider that did not support sendmail. Perhaps with time, I could have made it work for our mail server, but the duckling syndrome may have set in (yes, I still use vi and sometimes ed).

I'd be inclined to chose Postfix over Exim simply because Postfix is more popular, and new things (e.g. Mailman 3) tend to be implemented first for Postfix.

FWIW, I found postfix to be generally easier to deal with than the others. And the config files don't look like line noise with comments :).

grep -v ^\# exim.conf is too much?

I don't know if it's down to popularity or not, but I notice far more questions on this list concerning Postfix than I do exim.

We are currently running an old mailman instance and am planning to bring up the newest version of mailman and migrate to it. Current system uses sendmail. Since I now have a chance to change things, what is the best mail server to run on my mailman box? It will be talking to an exchange 2010 frontend server (current mailman system is doing that now). I can install sendmail or go with postfix or ??? This is running on a debian box.

Disclaimer: I am not an MTA expert. This is all personal opinion based on possibly limited experience.

I would go with either Postfix or Exim. Both integrate well with Mailman; http://www.exim.org/howto/mailman21.html and http://www.list.org/mailman-install/node12.html.

I have used both in Mailman environments, but Exim only in a Mailman development environment, Postfix both in development and on a production server handling both Mailman and other mail.

I have little experience with sendmail, and while it is possible to hijack Mailman's Postfix integration to use with sendmail, on the whole it seems 'clunkier' to configure, and I see no reason to chose sendmail over Postfix.

I'm not an "MTA expert," either. However, I've used sendmail ever since there was a sendmail. My systems are Solaris, which comes with a good implementation of sendmail, and my installations are all configured to do what I want them to do with regular e-mail.

I found adding Mailman to my existing setups to be quite simple. You'll need to manually add the Mailman pipes to the aliases, using the Mailman utility that gives you the list, but with the vi editor, it's a simply copy-and-paste. The only issue I had with integrating Mailman with sendmail was getting the Masquerades set up properly to host a different domain on my systems. however, that is covered in the O'Reilly "Bat Book," which you should have. It is not a Mailman issue, and proper configuration is done through the M4 macro files.
I haven't had to tamper with the sendmail.cf file separately.

I think that if you're familiar with sendmail, and have a satisfactory setup, do your upgrade, and integrate it with your current sendmail. I'm aware that most of the people posting to this list are using other MTA's on Linux systems, so there's little support here for a sendmail setup.

For reference, my links between Mailman and sendmail are through localhost to a local sendmail, and I also have a caching DNS server, all on the same box.

For me, switching to another MTA would mean a lot of work learning how to integrate all of the spam filtering and other things I already have integrated and working in sendmail.
