REST API: potential bug
by Peter Knowles Feb. 16, 2025

Feb. 16, 2025

I'm starting to develop against the REST API and found what might be a bug in the validation process. Sending a POST request with an "empty" payload returns 201 (created): http://localhost:8001/3.1/domains Since "mail_host" should be required at minimum to create a domain, this seems like there may be a bug with the REST API. The workaround for the moment is to add validation at the application layer, but the API should really be returning a 4xx code and error respectively.

install v3.3.11
by Jose Bernal Feb. 14, 2025

Feb. 14, 2025

I'd like to install Mailman v3.3.11. Are there instructions for installing from pip? If not, is there an alternate way to install this latest version? When executing: pip install mailman==3.3.11 I get: ERROR: No matching distribution found for mailman==3.3.11 Thank you,

Re: Moderation action "None" is misleading

Adding mailman-users(a)mailman3.org. Technical suggestions should go to distro channels or to Mailman's issue tracker: https://gitlab.com/mailman/mailman/-/issues/1176. Further discussion of technical details is best done there. Thomas Krichel writes: > Stephen J.

That's Debian's problem, as we currently don't support Python 3.13, although of course we intend to. This is the only issue that came up in a quick search of Mailman's issue tracker for Python 3.13 (but I did not check the other subprojects such as Postorius). I conclude that not a lot of work has been done on supporting Python 3.13 (rather than the optimistic "there's nothing to be done"). From Mailman's point of view, users have two excellent options for the forseeable future: (1) don't gateway list <-> newsgroups (2) install Mailman into a Python 3.9--3.12 virtual environment. I'm sympathetic to the needs of the Debian developers, and at this point for 99% of software it's perfectly reasonable to aim to use 3.13 in the next Debian release. Unfortunately for Mailman users on Debian hosts that's not high on our list of priorities since we recommend a virtual environment installation in any case. At present there seem to be three ways forward for Debian packaging: 1. Remove NNTP support. (In honor of larsi, I'd rather not.) 2. Add nntplib.py from the Python 3.12 nntplib, as a stopgap until option 3 can be implemented. I can't speak for other developers but we might be willing to add it as a contrib module, especially if that might make life easier for distro packagers. It's suboptimal though since that absolutely has to be considered techical debt that will need to be paid someday. 3. Port Mailman to pynntp (that may need to be Debian packaged, too), which has seen a revival of activity and two feature releases since 2023. My inclination as a Mailman core developer is not to participate actively in development of NNTP support in Mailman for Python 3.13+ unless we see an outpouring of support from site admins. However, I would be happy to answer questions and work on Mailman-side issues that are blocking or inconvenient for the NNTP work. Mark and Abhilash would undoubtedly contribute as well, on a time-available basis. > I certainly would love to build an alternative Mailman Debian > package that would be more up-to-date, but I don't want > to do it on my own. Debian and Python are compatible free software; just take the existing package metadata, in a recent Mailman (presumably the most recent release) drop in the most recent nntplib, and change all the import statements. mailman/src/mailman/mta/nntplib.py seems like a plausible location. IWBNI you could keep all Mailmanisms out of nntplib (because of the GPL) so any bugfixes or improvements could be available to the Python community. I think you could probably be up and running VERY quickly with that approach. Of course it wouldn't just slot into the next iteration of Debian because they have stringent QA (or maybe that could go into unstable?). I'm pretty sure it would be useful right away to a whole lot of people who are willing to use a PPA. Regards, Steve [View Less]

Login confusion
by Markus Grandpré Feb. 13, 2025

Feb. 13, 2025

Dear list, We've encountered an issue with Postorius after migrating from Mailman 2.1. It appears that Postorius is treating email addresses with differing capitalization as distinct user accounts. For example, <markus.grandpre(a)uni-konstanz.de> and <Markus.Grandpre(a)uni-konstanz.de> are being recognized as separate identities. This is causing significant confusion. Users registered with one capitalization pattern are not seeing the list subscriptions and settings that … [View More]

Pck files stuck in out queue
by Lieuallen, Thomas Otis Feb. 10, 2025

Feb. 10, 2025

Running Mailman 3.3.10 I have 11x pck files stuck in my out queue. There tends to always be a .bak file as well. If I run ‘ls -l’, the files are continually updated and rotated through, just as fast as I can look. The out runner is consuming copious CPU time. I was hoping this would help: [logging.runner] level: DEBUG But, if so, I don’t see the logs anywhere. I believe they’re all for one list. When I use ‘strings’ on one to get a hint of what’s inside, I see the list members at … [View More]

How to limit numbers of outgoing emails per connection
by Alain D D Williams Feb. 10, 2025

Feb. 10, 2025

Exim tells me "no immediate delivery: more than 30 messages received in one connection" The emails then sit in the exim queue until a queue runner kicks in - which happens once every 30 minutes. The result is considerable delays which makes list email conversations bouncy. Question: how do I tell MM3 to send no more than 30 emails in one connection to exim (via SMTP to localhost port 25) ? If that is not possible, how do I find the number that MM3 batches outgoing emails so that I can … [View More]

Hello, i'm really new to mailman3 and I've been using mm2.1 couple of years. It's really hardto understand documentation. But I'll do one in german language next time. I've got it installed ob Debian12 and it's working now. It takes a little more time to understand all settings and also the difference between postorius and django and what is when used for. But what I do not understand 'til now is how to add a new domain. My running config has one domain (e.g.) testdomain1.org and … [View More]
