Hi friends. I have multiple domains under MM3 (venv, postfix+postgres, Ubuntu 24.04LTS). Currently at version GNU Mailman 3.3.9 (Tom Sawyer).
Following some user complaints, I've discovered that one of the domains isn't working at all. Messages arrive via postfix and are in the MM smtp.log, but then generate a Python error in mailman.log. Other domains are working as usual.
The lists in this domain used to work (I can see messages in the archives, and have received copies). But I imported a bunch more MM2 lists since then, and perhaps there is a problem with one of their configurations.
Pointers to how to fix this will be appreciated! Here is the error from ~mailman/mm/var/logs/mailman.log:

... where it stays. Delivery never happens. I've tried with listname@lists.domain.tld as well as listname-owner@lists.domain.tld. The lists in the domain seem to be set up properly -- they used to work fine! I am suspicious the problem happened when I imported some other lists, but those imports didn't cause any errors.
I've done the usual sequence of restarting mailman services, rebooting the server, double-checking the configuration files, and reviewing the list settings.
Thanks for your help! ~ Greg
