Stephen: I will be collecting the information requested. However, the address "xxxxxxxx" is the superuser that lets me log in. "uuuu" is/are the address of the superuser I can't confirm.
Usually there's only one superuser account. There's no reason not to have more than one. Caveat, I've always used SQL UPDATE to toggle the superuser and staff bits on an existing account. But I would imagine using createsuperuser to make the additional superuser accounts would work as well. I do not understand how you created two instances of the "uuuu" address and linked user accounts. Maybe there's some kind of race condition
It does not appear that "uuuu" is in the address table.
That's definitely possible. It's probably just because it's never been used to attempt to post or be a member (including owner or moderator) of a list. Mailman core manages that table. I don't think Postorius updates it except as a side effect of creating list members, which is does through a proxy object which manages a core User object accessed via the REST API.
As for the unexplained addresses in there, mailman2 does not use mysql, does it?
No, Mailman 2 does not use SQL. But if you ever tried to migrate the list, the mailman2 addresses and subscriptions would be in Mailman 3's MySQL database until explicitly deleted or the database dropped, even if you deleted the original Mailman 3 installation and reinstalled.
