I am having another go with mailman3, being a long time MM2 user, but am getting increasingly frustrated.

I am using on Debian 12 (Bookworm) and have installed the various Debian packages - mailman3-full does that.

I have successfully started the mailman3 and mailman3-web services.

I went to: http://localhost/mailman3/postorius/domains/new/ 'Add a new domain' I enter a 'Mail Host' -- a domain that does exist on this machine I choose a Web host from the drop down list -- same as Mail Host

I click on 'Create Domain' and the page refreshes with the same information but under the Mail Host I see in red: {"title": "500 Internal Server Error"}

I eventually tracked it down. The problem was that I had signed in with an account "addw@localhost". That, for some reason, failed validation above. I hacked the database and changed to "addw@localhost.localdomain" and creating the new domain worked.

I could send email to addw@localhost - so at the MTA level it is correct.

So please can the initial account creation do the same validation as does adding a new domain.

I have looked but cannot find any documentation on postorius than https://docs.mailman3.org/projects/postorius/en/latest/ which is not helpful for a user or system admin. Can you point me to something better.
