We can create the list, I see no problem with this but since there is no clear and simple definition of "private" it will be up to the initial list admins to change any list settings to what they prefer, from the defaults.

@Dzahn Thank you very much! :) I can now access list management through Postorius. But I'm not getting relevant emails, I've checked my inbox and spam. Does the email contain any important information that I must know?

@Yiming I might actually be wrong about an email being generated by that command. It's possible I just assumed that because it was the case back in mailman2. If you can login and everything else works I think we are good. Maybe try to send a mail to the list and see if you receive that?

@Dzahn Ok, I got you. Everything is working fine for me, thanks again!
