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):

If I write a subscription email to any list of any other domain/site, I get back the request of confirmation and nothing in mailman.log.
And there is another difference to other sites: I get shown all lists of all sites/domains and not only the ones which belongs to this site/domain.
What could I have done wrong here? I really don't get it.
Thanks for help.
