Hi,

Can shed some light to this.
Actualy, it's probably several.
Just summarizing what I am about to do. I have an old mailman installation I
need to port to a new server.
The old one is based on EXIM as MTA but I would like to use postfix, because
this is the one I use on a lot of servers.
I need to make mailman virtual. I have around 20 mail domains to handle.
So I install a Ubuntu 10.04LTS 64 bit and get the packages for postfix apache2
and mailman and install
No problem.
When trying to make the virtual postfix/mailman integration, I ran across a
post recommending to use mailman 2.1.14
Ok - I removed the mailman package from Ubuntu , actually 2.1.13 - downloaded
the 2.1.14 source
Ran configure, make and make install all seems OK.
It's because of the very sort of permission problems you hit that I don't
generally do this. Unless you really need to run Mailman 2.1.14, 2.1.13
should be plenty fine enough. One server I help administer still runs
Debian Lenny with Mailman 2.1.11 and again works fine for me.
However, I did have to hand-compile Mailman on a Ubuntu system for work (I
no longer have access to this box) because I needed to have multiple
installs for separate domains. I made some notes. See below.
I have added following to mm_cfg.py
##################################################
MTA = "Postfix"
# Put YOUR site-specific settings below this line.
POSTFIX_STYLE_VIRTUAL_DOMAINS = [ 'test.sdu.dk',
'some.other.domain',
......
add_virtualhost('test.sdu.dk','test.sdu.dk'
add_virtualhost('some.other.domain','some.other.domain')
called check_perms -f
called genaliases
and checked that i have the files :
my@mls2:/usr/local/mailman$ ll data/alia*
-rw-rw---- 1 mailman mailman 114222 2011-06-10 09:04 data/aliases
-rw-rw---- 1 mailman mailman 172032 2011-06-10 09:04 data/aliases.db
my@mls2:/usr/local/mailman$ ll data/virt*
-rw-rw---- 1 mailman mailman 86149 2011-06-10 09:04 data/virtual-mailman
-rw-rw---- 1 mailman mailman 176128 2011-06-10 09:04 data/virtual-mailman.db
Added to postfix main.cf:
transport_maps = hash:/etc/postfix/transport
alias_maps = hash:/etc/aliases, hash:/usr/local/mailman/data/aliases
alias_database = hash:/etc/aliases, hash:/usr/local/mailman/data/aliases
You don't need this, and in fact if I recall correctly, it's bad to have
this.
virtual_alias_maps = hash:/usr/local/mailman/data/virtual-mailman
You don't have any other virtual alias domains?
mailman_destination_recipient_limit = 1
I've never seen this one before.
AND in transport i have entries like:
test.sdu.dk mailman:
some.other.domain mailman:
You're mixing up methods here.
You can set up Mailman+Postfix in one of two ways, using virtual alias
domains or using a Mailman-specific domain (e.g. lists.example.com) and
using a transport. You seem to have employed both here which is not
necessary, and by definition only one will ever work.
I've never used the transport option and consider it unnecessary, but it
may be simpler for someone who is using a subdomain specifically for lists
and no other Email.
Not sure which documentation you're using, but I recommend the official
installation guide, specifically the section on Postfix. It's a little
confusing but Email administration is a confusing business.

Then when trying to send a mail to a new list I get the following in mail.log
Jun 10 08:44:22 mls2 Mailman mail-wrapper: Group mismatch error. Mailman expected the mail#012wrapper script

OK I go to the mailman source and recompile as suggested and get

Like I said, you run the risk of running into these problems if you try to
compile Mailman from source under Debian or a Debian-based system (and
probably other package-based systems). Debian is tricky because they use
different usernames than stock Mailman, though of course the reason is so
that you have consistant user/group names across software packages.
Here's some info if you decide you want to persist with the
compile-it-yourself method.
From the notes I made, you'll need the folllowing configure line based on
that used for the Debian package:
./configure --with-username=list --with-groupname=list
--with-mail-gid=list --with-cgi-gid=www-data
You'll also want to use --prefix if you want to install somewhere special
(I forget what the default is).
Prefix dir must be owner/group list. Must be group writeable and setgid.
You might want to "umask 002" before running make.
After make install:
cd $prefix
bin/check_perms
then
chown www-data archives/private
chmod o-x archives/private
Run bin/genailiases from $prefix
Check that data/aliases and data/virtual-mailman are owned by list and
are world-writeable (try check-perms again after genaliases)
It's almost two years since I made these notes for myself so I don't
remember the finer points. I've set up Mailman on several other systems
and just used the packaged versions.
HTH,
Geoff.
