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 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

Weird emails
by Paul Tomblin Feb. 26, 2026

Feb. 26, 2026

I've got my server set up correctly (I hope) and on an https connection, and I *think* I've got it set up so mailman-web will only respond on localhost:8000, but I occasionally get a flood of emails like this: > Internal Server Error: /admin/login/ > > DoesNotExist at /admin/login/ > Site matching query does not exist. Followed by a bunch of Django stuff, followed by > HTTP__X__CLIENT_IP = '127.0.0.1' > HTTP__X__FORWARDED_FOR = '127.0.0.1, 185.177.72.38' > HTTP__X__FORWARDED_HOST = '96.126.110.20' > HTTP__X__FORWARDED_SERVER = 'list.xcski.com' > HTTP__X__FORWARED = '127.0.0.1' > HTTP__X__HOST = '127.0.0.1' > HTTP__X__ORIGINATING_IP = '127.0.0.1' > HTTP__X__REAL_IP = '127.0.0.1' > PATH_INFO = '/admin/login/' > QUERY_STRING = 'next=/admin/' > REMOTE_ADDR = '127.0.0.1' The HTTP_X_FORWARDED_FOR was a clue where it was coming from, and grepping through my apache access logs shows a script kiddie at 185.177.72.38 hammering a miliion urls, 99% of them 404s. Is there any way the code could just return a 403 or 418 instead of getting a python error? -- Paul Tomblin

Documentation errors
by Paul Tomblin Feb. 23, 2026

Feb. 23, 2026

On the documentation about migration at https://docs.mailman3.org/en/latest/migration.html, there are two commands that start `python manage.py hyper kitty_import|update_index_on_list`, but there is no manage.py installed if you install Mailman and Mailman web following the instructions. Instead, I was able to run them using `mailman-web hyperkitty_import|update_index_one_list` instead. What is the correct method for reporting these errors?

Can't import from Mailman 2.1
by Paul Tomblin Feb. 23, 2026

Feb. 23, 2026

I set up a new Mailman site using 3.3.10, and copied over my files from my old mailman site (using 2.1.34). I created a new domain, and a new list, and tried to import the settings from the old pickle file using mailman import21 pt-test(a)browncroftna.org /var/tmp/var.lib.mailman/lists/pt-test/config.pck (in the virtual environment shell) but I get the following error ``` File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/utilities/importer.py", line 512, in import_config_pck default_value = getUtility(ITemplateLoader).get(newvar, mlist) File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/model/template.py", line 211, in get path, fp = find(default_uri, mlist, code) ~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/utilities/i18n.py", line 157, in find for search_path in raw_search_order: ^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/utilities/i18n.py", line 117, in search templates_dir = str(resources.enter_context( ~~~~~~~~~~~~~~~~~~~~~~~^ files('mailman').joinpath('templates'))) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/contextlib.py", line 528, in enter_context raise TypeError(f"'{cls.__module__}.{cls.__qualname__}' object does " f"not support the context manager protocol") from None TypeError: 'pathlib._local.PosixPath' object does not support the context manager protocol ``` All I can find on Google is a suggestion that I have a non-empty `bounce_info`, but `dumpdb` shows it as empty.

Customizing Postorios web templates
by Stefan Bethke Feb. 23, 2026

Feb. 23, 2026

Hi, I have two list servers that I would like customize the web pages for, specifically I need to add some legal information to the footer, and I might want to apply some light branding to the site. I can't find any hints on how to do that, maybe I'm looking in the wrong place? If Postorious does not currently allow that outright, it seems I would need to fork mailman/postorious, replace templates like https://gitlab.com/mailman/postorius/-/blob/master/src/postorius/templates/…, and build the package myself. Is this assessment correct? If so, would there be interest in adding a feature to define some blocks that can be overridden more easily, especially during deployment and without having to build custom Python packages?

Digestion debugging
by John Price Feb. 21, 2026

Feb. 21, 2026

I'm having trouble getting digests to work. When I try to manually send one, it does nothing, and then the digest gets deleted (I guess?). I would love it if the documentation explained a bit more how the process works. How are the files gathered? What file can I backup and later restore if I'm debugging it? Also, how are the digest issue and volume numbers work? Is there any way to control that? Since I've been running digests for decades, can I set the volume and issue to what I want so that the numbering continues from where the other installation left off? Thanks, John -- Why do they lock gas station bathrooms? Are they afraid someone will clean them?
