Re: Heads up: settings.ACCOUNT_AUTHENTICATION_METHOD is deprecated

This issue is still there for me. I am starting a new installation from scratch, with the venv method in 3.13.

Accept these non-members
by Lars Bjørndal March 6, 2026

March 6, 2026

Hi, list! I have an announce only Mailman3 list. When I log into the web interface as an admin user, and go to the specified list, and choose Settings, I find the Message Acceptance tab. There, I find the edit field Accept these non-members. But this field is empty, although I know that some people have permissions and are able to post to this list. How can I find the list of these non-members and add more people or delete someone? I'm running Mailman version 3.3.10, and mailman-web version 4.2.21. Any hints? Thanks, Lars

How to upgrade to 3.10
by Paul Tomblin March 5, 2026

March 5, 2026

I installed 3.9 with pip last week, but i want to upgrade to 3.10. But pip install -U mailman postorius django-mailman3 hyperkitty mailman-web doesn't upgrade it. Requirement already satisfied: mailman in ./venv/lib/python3.13/site-packages (3.3.9) Collecting mailman Using cached mailman-3.3.10-py3-none-any.whl.metadata (2.4 kB) Requirement already satisfied: postorius in ./venv/lib/python3.13/site-packages (1.3.13) ... a bunch of these ... INFO: pip is looking at multiple versions of mailman to determine which version is compatible with other requirements. This could take a while. Requirement already satisfied: python-dateutil>=2.0 in ./venv/lib/python3.13/site-packages (from mailman) (2.9.0.post0) ...a bunch more... -- Paul Tomblin

Can't add emails to accept_these_nonmembers
by Ibiam Chihurumnaya March 4, 2026

March 4, 2026

I need to set some nonmembers to a list as these members send message to the list, but don't need to receive any message from the list. I've used list_name.settings['accept_these_nonmembers'].append to add members to the list, but it gets discarded once I run list_name.settings.save().

Debian bug report
by Paul Tomblin March 3, 2026

March 3, 2026

So I went to submit a bug report to Debian about the fact that the mailman3-web page drags in nginx for no reason. Turns out that the bug had been reported in 2021 and nobody who worked on it who understood mailman understood apache and nobody who worked on it who understood apache understood mailman[1]. So I submitted an update. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1002795 [1] Literally, one of the developers said Thanks, I admit initially I had no plan on supporting apache2 as I don't use it. Jonas did that part and therefore I did not follow at all. -- Paul Tomblin

What depends on libapache2-mod-proxy-uwsgi? Mailman core doesn't depend on that at all. It always uses gunicorn as the WSGI server for the REST API, and the Apache config uses ProxyPass on port localhost:8001. And sez who? Are you asking apt or dpkg? I thought you have installed via pip into a virtual environment -- what apt and dpkg think about Mailman dependencies is irrelevant. > > > Is it possible to upgrade to 3.10 with pip? If you installed using Debian, you can't upgrade with pip -- that's a Debian restriction. You have to remove the Debian package(s), and create a virtual environment, typically under /opt/mailman, to install the Mailman suite into. Then, if you have already working lists, you have to either (1) "very carefully" move all the /var/lib/mailman data from your working Debian install into /opt/mailman in appropriate places, or (2) configure the new Mailman to look for data where Debian put it (if you're lucky you can re-use Debian's /etc/mailman3/mailman.cfg for that, although they may have patched the source). The /var data is the queues (mostly bad and shunt, but you may have orphaned qfiles in out, and very very rarely in other queues), the logs, and any in-progress digests being accumulated. The list configurations, user profiles, and most volatile data (eg, pending confirmations) will be in your database. You can use the Debian packaged database, just point the new Mailman at that. > > Yes: see https://pypi.org/project/mailman/. > > Use python3 -m pip install --upgrade mailman. > > Nope, that doesn't work. > python3 -m pip install --upgrade mailman 2>&1 | tee bar > Requirement already satisfied: mailman in ./venv/lib/python3.13/site-packages (3.3.9) Where is '.'? If it's under /var/lib or /var/share, you've got Debian's mailman and you can't upgrade with pip. You want it to be under /usr/local (ugh) or /opt/mailman (happy face). > Collecting mailman > Using cached mailman-3.3.10-py3-none-any.whl.metadata (2.4 kB) [...] > Requirement already satisfied: zope.schema>=4.9 in ./venv/lib/python3.13/site-packages (from zope.configuration->mailman) (8.1) Are you saying pip returns to the shell prompt without doing anything after that? > If I'm reading that right, I have to guess which requirements I > need to force an update on before it will upgrade mailman. No, that's saying all requirements are satisfied for mailman-3.3.10 as far as I can tell. Are you working as the right user? (If you've previously used Debian packages and have working lists, you probably want to continue using Debian's preferred 'list' user, otherwise you may create a 'mailman' user.) If it's not lacking write permissions to the virtual environment, I have no idea why this isn't working. The only thing I can suggest is the same as Mark, force version 3.3.10 with python3 -m pip install --upgrade mailman==3.3.10 and see what happens.
