Mark,
Thank you for your helpful reply. Considering Brad isn't available at this time, would you know of anyone you could recommend who is experienced with OS X Server to help me with my problem ? All I need is for someone who is experienced with OS Server and understands its System Administrator tool to log in on my server remotely and review my settings to make sure I haven't done anything wrong and possibly make a few corrections if they happen to be necessary. It goes without saying that I will be happy to pay for the consultation fee. After I am sure that everything is set-up properly on the server I will then continue with Mailman and decide whether I should just use the one bundled with OS X Server or if I should download it and do new install.
