I'm moving our groups to mailman3 (http://we.lurk.org). Enjoying it so far!
I've mass-subscribed people via postorius. However the subscribers don't have django (postorius/hyperkitty) logins. It seems they only exist on the mailman side, not the django side.
If they go through the process of creating an account in postorius, they can configure their mailing list subscriptions, but this is a bit fiddly.
Is this expected behaviour? It would be great if they could be sent a temporary link to set a password and go.
