I have successfully setup a second domain with my Mailman3 setup. I also created a list using the second domain. So I have two domains with one list each. The issue I see at this point is all of the lists are shown via Postorius regardless of the list domain used. Is it possible to have only the lists to show that are part of the domain being used to access? For example:
Only firstname.lastname@example.org show up.
http://domainb.com/postorius/lists/ Only email@example.com show up.
Right now both domaina AND domainb lists showup regardless of the domain being used to access Postorius. The same goes for Hyperkitty as well.
