WE are currently using mailman2. I have the task to setup and install a maiman3 server. Postfix is installed and working. Can anybody point me to a link where the actual installation is described using RHEL 7 or RHEL 8. This will be a >hardened DISA compliant server, so I am trying to avoid installing compilers and tools that are not part of the standard RHEL 7 repos.
Have you looked at creating a development environment using a Python3 venv somewhere else (eg another server or container) then copying the venv out to the production server?
I found the following very useful: https://wiki.list.org/DOC/Mailman%203%20installation%20experience
Granted you will need RedHat packages for Python, Postfix and the web server, but everything else can be installed in the Python virtual environment and ran from there using the scripts on that site with minor tweaking.
Hope this helps. Andrew.
