Hi all, next problem. I got a proper configuration (so i thought, but when starting, mailman3 exits. The output of journalctl -xeu mailman3.service ends with: Sep 05 17:33:23 bywater mailman[223227]: File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/commands/cli_ga> Sep 05 17:33:23 bywater mailman[223227]: import nntplib Sep 05 17:33:23 bywater mailman[223227]: ModuleNotFoundError: No module named 'nntplib' Sep 05 17:33:23 bywater systemd[1]: mailman3.service: Control process exited, code=exited, status=1/FAILURE ░░ Subject: Unit process exited ░░ Defined-By: systemd ░░ Support: http://www.ubuntu.com/support ░░ ░░ An ExecStart= process belonging to unit mailman3.service has exited. ░░ ░░ The process' exit code is 'exited' and its exit status is 1.

Mailman3 virtualenv installation: missing data
by qno-mailman＠qno.de Sept. 5, 2025

Hi all, i tried to install Mailman3 according to https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-inst…. I’m using Mariadb instead of PostgreSQL, but that is no problem until now. Where i fail: I have to make an entry var_dir: /opt/mailman/mm/var in /etc/mailman3/mailman.cfg. But there is no directory /opt/mailman/mm, and there are no subdirectories. No $var_dir, no postfix_lmtp, no postfix_transports. Where do i get those files from? TIA QNo

Question: as Admin, I disabled the self-registration via settings.py. What is the correct method to register a few new users now?

Disabled by line ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter' (via https://gitlab.com/mailman/django-mailman3/-/merge_requests/129 ) When I want to register a few new users, I need to comment this line and restart mailmanweb. Question: is there a better method for admins to register a few new persons to Hyperkitty/Postorius so that they can act as owners and moderators of some of the lists?
