Mailman Core: REST API: Member Subscription Invitation
by Peter Knowles Feb. 20, 2025

Feb. 20, 2025

Product: Mailman Core Version: 3.3.10 When I post an "invite" to the REST API: http://localhost:8001/3.1/members Params: list_id = list.domain.tld subscriber = some(a)email.address display_name = Some Name invitation = true Should Mailman Core be attempting to send an "invitation" email to the "subscriber" address, or is this the job of the "client" calling the API? I understand the API does return "token", and "token_owner" on success, which I assume the "token" would be used for a subsequent "verification" process. I'm developing my own "frontend" for "subscribers", "moderators", "list admins", and "system admins" respectively. Sort of working through understanding what Core does and does not do itself.

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.

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. Turnbull writes > > Debian has traditionally been quite slow to update Mailman, > > And now it has the addition issue that Debian testing python > standard it 3.13, so the nntplib is no longer supported. > Thus the current Mailman debian testing appears broken. 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

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 the bottom (recipients). One of them consistently has ‘!’ before their email address. Not sure if that’s a clue. Just no other reason to suspect that, though. Ideas on where/how to track down the status of these files and fix whatever’s broken? Thank you Tom Lieuallen Oregon State University

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 configure exim to match (as I did with MM2) ? I see documentation pages like the following. They are useless to me, incomprehensible without a lot of learning. I program in several languages but only a little Python. What I am looking for is a setting in a config file. https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/runners/do… -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

User with abo to list can not set to another moderation flag
by Chris Feb. 8, 2025

Feb. 8, 2025

Hi again, I've one weird problem. I've some lists and a user which is a moderator on both lists. Steps to reproduce Postorius -> Users -> search for the user to change -> manage Both Lists are shown Moderarion Flag on a newer List was changed from standard to accept -> On the older list I've tried from Standard to Accept -> click on the button to accept changes result in reverting to "standard" (the setting which I want to change). Any hints on that? (can't find any difference between those lists except name und descriptions. )

How to add new Domain?
by c.benner＠apd-it.eu Feb. 7, 2025

Feb. 7, 2025

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 everything is working fine. The Domain has a virtualhost which listens on *:443 (with LE cert) Postfix works like a charm. The interface of the machine is bound to one IP Address public but for example here written as: 192.168.200.15 Id like to add a new Domain. My first step would be to add another IP Address to the interface: (e.g.) 192.168.200.16 Then I'll change the virtual host settings in apache conf from first domain which is actually listeing to *:443 to 192.168.200.15:443 And add a second site with 192.168.200.16:443 So the "physical" part is done Is that right 'til now? After that I'll go to the admin page xxxx/mailman3/admin which brings django admin page up. On that page I'll add "websites" and add testdomain2.net Last step is adding "mail domain" site: testdomain2.net mail domain: testdomain2.net After that I can add lists to that domain and mails to any list @testdomain2,net should be routed right? Maybe I'm to old (56yrs) but I've read a lot of documentation and everything was clear and understandable. It was never a question of linux or windows OS but on who'S writing the doc. I can't find any doc about the web part? What about Users having no acces to the shell but the Web-Frontend? Some pictures and a "How to" and "what if" would be great! But it's alos possible that I'm not finding it and it's somewhere out there. Thanks in advance.

Error while mass operation, no progress display while mass operation is running
by Markus Grandpré Feb. 7, 2025

Feb. 7, 2025

Dear List, At the University of Konstanz we have mailing list administrators who frequently add and remove up to 10000 (and sometimes more) list members. I have therefore tested the “Mass subscription” and “Mass removal” operations and found that both the “Remove ALL members” operation and the “Mass subscription” operation report an internal server error on the website, but continue to run in the background until all new members have been successfully added or deleted. Unfortunately, I have not found any error message in the log files. I also tested that mass operations “Remove listed users” and “Remove Selected” ran successfully and without any errors. Regardless of whether a mass operation process runs without errors or continues to run despite an error, I find it hard that Postorius does not display the progress of such a mass operation in order to monitor the process, as mass operations with more than 1000 members are very time-consuming. Perhaps this could be changed in a future version of Postorius?
