're' problem is sending messages to queue/shunt for an entire domain
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:

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
It looks like there was a problem in one or more of the legacy banned emails.
I deleted all entries in the 'ban' table via PostgreSQL's CLI, and the logs no longer show the error.

Yes, the issue was an invalid regexp in the ban list.
multiple repeat at position 11
Some entry beginning with ^ had something like **, +*, etc. at
position 11.
