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

How to upgrade to 3.10
by Paul Tomblin March 3, 2026

March 3, 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 3, 2026

March 3, 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().

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.

Django 5.2 LTS and mailman 3
by dlb-ml＠anl.gov March 2, 2026

March 2, 2026

I noticed that Django 4.2 is nearing EOL status in April (no specific day in April is given): https://www.djangoproject.com/download/ I also noticed that there's a planned update to add support for 5.2 to mailman-web: https://gitlab.com/mailman/mailman-web/-/blob/master/README.rst Is this expected to be released before 4.2 goes EOL? Is there a rough time line? Thanks!

High IO for 8+ hours
by Paul Tomblin March 2, 2026

March 2, 2026

First time running runjobs monthly since I installed it a few days ago, and it's been maxing out I/O for the last 8 hours. There doesn't appear to be any logging going on. I am using Xapian, by the way. Is this normal? Is this going to happen every month, or is the first month special? -- Paul Tomblin

Debian upgrade Hyperkitty not archiving
by Phil Steel-Wilson March 1, 2026

March 1, 2026

Hi List, I may be in the wrong place so bear with me. I'm working at a volunteer organization with around a dozen mailing lists that were previously on mm2 that have been upgraded to mm3 with the upgrade to debian trixie. Mailman is running and the lists all work ok but i found 1800 mails in the shunt queue. Hyperkitty also shows all the old archives pre 2020 the same as in the django console. When i tried to unshunt the mails they moved to the bad queue. How do i find whats wrong here?

message duplication and an NNTP related error
by Laurens Kils-Huetten Feb. 28, 2026

Feb. 28, 2026

Good day, I have recently installed mailman3 on a Debian trixie system. While I managed to set up most of it (the mailing lists, postorius and also a working gateway to our inn2 news server) I'm seeing a weird duplication of messages, that seems to be related to the error messages posted below. When I switch off gating to nntp the duplication stops. Also only mail messages are duplicated, not the postings on the news server. Any pointers as to what to look into, or how to remedy this problem are greatly appreciated :) Thanks, Laurens here come the error logs: Feb 23 20:39:08 2026 (2776528) ACCEPT: <e4938b85cbd75c0b04867514fc0b8ad9(a)betola.de> Feb 23 20:39:10 2026 (2776528) ACCEPT: <e4938b85cbd75c0b04867514fc0b8ad9(a)betola.de> Feb 23 20:39:12 2026 (2776530) <e4938b85cbd75c0b04867514fc0b8ad9(a)betola.de> NNTP error for test(a)grenzland.club Traceback (most recent call last): File "/usr/lib/python3/dist-packages/mailman/runners/nntp.py", line 94, in _dispose conn.post(fp) ~~~~~~~~~^^^^ File "/usr/lib/python3/dist-packages/nntplib/__init__.py", line 916, in post return self._post('POST', data) ~~~~~~~~~~^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/nntplib/__init__.py", line 909, in _post return self._getresp() ~~~~~~~~~~~~~^^ File "/usr/lib/python3/dist-packages/nntplib/__init__.py", line 492, in _getresp raise NNTPTemporaryError(resp) nntplib.NNTPTemporaryError: 441 Can't set system Injection-Info header field
