Comment 4 for bug 1756009

I am relatively sure that none of the users have changed the settings. But anyway, I checked the settings of two of the users who no longer get email (see attachment). So I don't think any of the reasons listed in https://bugs.launchpad.net/mailman/+bug/1756009/comments/1 come into question here. In the emails also only the email list was specified as recipient.
Unfortunately I did not find the bin/list_members program. Mailman is installed in two Docker containers and I have logged in there and searched with find from /.

I sent a who command for the list via email to the server. The reply email also correctly delivered the 138 members.
I also created a test list with only the two email addresses I mentioned above and with my email address. When I send an email to the test list, the email is also delivered to the two addresses.

Thanks for your help.
