I put this on the wiki two years ago:
http:/
/dbmail.org/dokuwiki/doku.php?id=mailman

However, I remember seeing a much better way to do this on
the mailing
list more recently. Something about mailman domains. I don't
recall the
details. Let's update the wiki with whatever the
best-practice is.

That was me talking about the mailman transport in postfix.
All documented in
the mailman mta integration docs.

/etc/postfix/transport:

lists.mydomain.com	mailman:

/etc/postfix/master.cf:

mailman unix  -       n       n       -       -       pipe
flags=FR user=list
	argv=/usr/lib/mailman/bin/postfix-to-mailman.py $
$

The mentioned python script (postfix-to-mailman.py) contains
the above setup
documentation as well.

After setting this up, all you need to do is create lists
(newlist listname),
and you're all set. No need to manage aliases.

The approach above makes it cumbersome to use anything other
than the 
list addresses and the administrative addresses
postfix-to-mailman.py 
knows about (currently postmaster, abuse,
mailer-daemon). In my case 
I wanted to add admin and webmaster, for which I'd have to
edit said 
python script which seemed messy. Then I realized that
mailman has 
automatic alias management for quite some time now. The
relevant option 
in the config is

MTA = 'Postfix'

which will result in the file /var/lib/mailman/data/aliases
populated 
with pipes to the correct binaries, automatically kept
up-to-date by 
internal mailman hooks, and a postalias-ed result in
aliases.db. Then 
all you have to do is populate the postfix recipient list as
you would 
do otherwise:

# use system-level aliases + automatically generated alias
lists
alias_maps = hash:/etc/postfix_promo/admin_aliases 
hash:/var/lib/mailman/data/aliases
# there is nothing that can be updated by newaliases
alias_database =
# we only accept mail to existing lists and admin addresses
local_recipient_maps = $alias_maps

No transport trickery and very straightforward.

On a side note mailman scales extremely bad when you reach
50k+ 
subscribers. I am planning to migrate to sympa[1], but have
not had the 
time to make the necessary research. Anyone using this
software?

Not yet, but thanks for the hint. I use mailman since years,
runs 
smoothly, but is not really good to administer: Users cannot
create 
lists or copy existing lists with subscribers, etc., so the

administration kept being my part. Looks like with sympa I
could 
finally give away that work.

I need a new ML server, and was just fighting with mailman
again - I 
don't like it too much, so I'll look into sympa now.
