Hello,
This is an issue with Mailman 3.3.10 and Python >= 3.13 fixed by https://gitlab.com/mailman/mailman/-/merge_requests/1348
Here again if you want to upgrade Mailman core you can do
pip install --upgrade git+https://gitlab.com/mailman/mailman
to get the latest from gitlab.
Is it safe to use latest from gitlab for production usage?
With python-3.13 in Debian stable it would be nice if we could get a new relase of mailman3 with all the fixes for python-3.13.
Regards, Bernhard
