[Mailman-Users] Mailman list sends but doesn't receive mail.

It has been suggested to me an approach that I thought might resolve the
problem I am experiencing with the changes constantly made by OS X Server
Admin application to Mailman's mm_cfg.py file. An it specialist who helped
me review my OS X Server set-up and DNS settings suggested that I should
change permissions on this file in order to prevent OS X Server from editing
it. He tried changing the permissions on the file to rw-r--r-- but it still
didn't work. From my limited knowledge of UNIX and terminal it appears to me
that the ownership of the file belongs to -Mailman. Is this right ?

Can either the permissions or the ownership (and perhaps both) on this file
be modified so as to keep OS X Server from editing it ? Could these
modifications have any adverse effect on Mailman's behavior or would the
program work fine with this file as a read-only file ?

What do you think ?

According to the it specialist my set-up and DNS settings are fine. This is
a relief. Now I know that the issue is very likely related to Apple's (poor)
implementation of Mailman. I know one choice I have is to bypass this
bundled version included with OS X Server and install a fresh version of
Mailman. However, considering the work and time involved I would prefer, if
possible, to work with the version I have and that is already set-up.

What are your thoughts on this matter ?

Thank you as always for your help,
