The Mailman stack is not up-to-date and needs upgrading.
The problem is that newer versions of Mailman require Python >= 3.5 and we were currently building it with Python 3.4 in EPEL. To rebuild a newer Mailman and its dependences we need them ported to the new python36 in EPEL.
There has been a proposal to enable Python3.6 for the python packages in EPEL but it's still at the planning stage. It's a lot of grunt work. See https://email@example.com/thread/WIDTOW7HUOJI3QO4WNCG2DTTF5B3CLBE/
Python3.6 will arrive in EPEL-7 after April 2nd. This can proceed next.
