I'm sorry for asking this... But I can't quite figure out if mailman is used, and needed, by the ISPConfig Mailing List, to work, or are they two separate things? I've never used it and never think I will... And IF I ever need a mailing list, I will prefer to use ISPConfig to manage it... So... Can I just remove mailman from a running server (skip installation on a new) ? I did try to create a mailing list in ISPConfig, and I don't get any new lists when looking at "/cgi-bin/mailman/listinfo"... So I'm also wondering if it even works? (If needed, I'm running Ubuntu 14.04.5 LTS, ISPConfig 3.1.1p1 and mailman 1:2.1.16-2ubuntu.) ### UPDATE ### After a while and fumbling around, I found out that mailman IS needed for ISPConfig Maling List... The website (/cgi-bin/mailman/listinfo and admin) i were looking at, were at my servers url and not the domain I have created the mailing list under... So to be sure that all services works and can be used later on, I will keep mailman installed and install it in all new setups.
