i've followed the threads on qmail and exim but i'm a bit confused. it seems that mailman does not yet support qmail but may soon.

If I interpreted Balazs correctly, the only "problem" with Qmail was that Mailman-generated mail (i.e. subscription confirmations, password reminders etc., but _not_ normal sent-to-a-list mail) doesn't have Date: or Message-ID: headers.

I believe most sendmail equivalents insert these headers when they're missing, but apparently Qmail does not. Thus, if there is a some sendmail equivalent between some user and Mailman running on Qmail, that user will get mail with these headers.

does it actually work with exim?

Yes. This is the Mailman-relevant parts of my Exim configuration:

# Transport mailman_list_pipe: driver = pipe allow_commands = /local/Mailman/mail/wrapper user = mailman return_fail_output

# Director mailman_lists: driver = aliasfile search_type = lsearch file = /local/Mailman/data/MTA_aliases pipe_transport = mailman_list_pipe

(Whee, I just _love_ not having to clutter with sendmail.cf anymore :)

we're using sendmail and need to either upgrade to 8.9 or change MTA's.

Exim is designed to be a sendmail drop-in replacement -- very nearly all the sendmail command-line options work in the same way when given to Exim.

Another *big* plus (in my eyes, anyway) with Exim is that the author is extremely helpful, and on a daily basis shares his wisdom with the rest of the <exim-users@exim.org> mailing list (which I'm sad to say isn't a Mailman list ;).

[ I had a look at qmail some months ago, and as soon as I realized that you need to define a bunch of different qmail users on any box where you might want to pipe something into /usr/lib/sendmail (due to it's compartmentalized model of execution), I realized it wasn't really my piece of cake. Postfix looks good, but isn't mature enough yet, IMHO. ]
