RFE: Edit message footer settings through web UI
While checking something on CPython's core-workflow mailing list, I noticed that the message footer currently contains duplicated content (see Brett's quote of my message in https://mail.python.org/mm3/archives/list/core-workflow@python.org/message/DQVN77FH7WTR5VEF3X7FHQ7U527Q2AIO/ for an example).
However, the message footer template doesn't seem to be configurable from Postorius, and @msapiro's comment at mailman#426 (closed) suggests that this is currently something that requires admin access to the mailman server itself.
Would it be feasible to allow editing of list specific templates through the web admin interface?
