Hi,
I added a new site in Django: lists.example.com
Usually I click on 'view site' and I can add a Domain in Postorios. In this case I get an error message and I need to add a Domain in Django. Then I can go to 'view site'.
I can create a mailing list there. However when I send an email to be subscribed, I get the following in mailman.log (and nothing else happens):
Oct 09 13:46:24 2025 (110452) deque: do_confirm_verify Traceback (most recent call last): ... File "/usr/lib/python3/dist-packages/mailman/model/domain.py", line 177, in __getitem__ raise KeyError(mail_host) KeyError: 'lists.example.com'
It appears you don't have a domain in Mailman core with mail_host = 'lists.example.com'.
Do you see one in Postorius' domains view? If not, perhaps you need to add it.
