[Pkg-mailman-hackers] Bug#396537: mailman: README.Exim4.Debian needs to mention groups

[Ian Wienand]

Package: mailman
Version: 2.1.9-2
Severity: normal
Tags: patch

Hi,

After followign the instructions, I got a traceback when creating a
list via the web interface which came down to 

admin(510): RuntimeError: command failed: chgrp Debian-exim
/var/lib/mailman/data/virtual-mailman (status: 1, Operation not
permitted)admin

The problem was the webserver user, www-data, doesn't have permissions
to do that chgrp.

I'd like to suggest something like the following.  I'm not sure if it
has secuirty impliciations; I'd like suggestions for any other
work-arounds.

Thanks!

 and list all your Mailman domains in "POSTFIX_STYLE_VIRTUAL_DOMAINS".
 
+When a new group is created, the correct aliases will be written into
+the file /var/lib/mailman/data/virtual-mailman.  The above chgrp
+command is run as the webserver (usually www-data), however
+Debian-exim needs to be able to access this file.  To allow the
+www-data to do the chgrp command, add the www-data to the Debian-exim
+group; e.g. in /etc/group should have a line similar to

+Debian-exim:x:105:www-data

 Put this in your exim4 main configuration (if you use a split config,
 for example /etc/exim4/conf.d/main/04_local_mailman_macros)
