BTW, is Python 3 recommended for Mailman 3?
No. Mailman 3 does not yet work with Python 3. It requires Python 2.6 or Python 2.7
I see a bunch of stuff on virtualenv, but if it is simpler to not user virtualenv and to just have one version of Python installed, I'll go that direction.
It's really up to you. virtualenv will allow you to isolate your Mailman 3 environment from the rest of your system so that, for example, the Django you install as part of Postorius won't conflict with other Django installs, etc ...
