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

Postorius extremely slow on some of the mailinglists
by Eric Broens Feb. 10, 2025

Feb. 10, 2025

Hi, Postorius became extremely slow recently on some of our mailinglists, but not on all of them. Postorius even times out when opening some of them (https://<hostname>/postorius/lists/<mailing_list>.<domain>/) and shows the message "Mailman REST API not available. Please start Mailman core." This only happens when I am logged in (as administrator), but not when I am not logged in. It seems to be independent on the number of subscribers on the particular mailing list. Below you'll find an extract from the logs for a case where it timed out, and for a case where the page showed up after a long time. Mainly "GET /3.1/lists/<mailing_list>@<domain>/requests HTTP/1.1" takes a long time. There is nothing unusual going on regarding database queries, and mails are delivered normally. Any idea why this happens and how it can be solved?

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?

Which folder should I share between pods with kubernetees persistentVolumeClaim ?
by antoine.depoisier＠ikmail.com Feb. 7, 2025

Feb. 7, 2025

I use mailman with kubernetees, and I have four pods. I currently use persistentVolumeClaim for two folders in the mailman configuration "cache" and "messages". I share these folders, as mailman needs to be consistent for these two folders, but I'm wondering if I should share other folders as well, like locks and such. There are all the folders in mailman archives cache data etc lists locks logs master.pid messages queue templates I ask this question because I often have a problem when creating a mailing list. I think I have a problem with the locks, but I'm not sure if the problem is due to the fact that the locks folder is not shared. If you want more details, here's the trace I sometimes get, when someone tries to create a mailing list: File "falcon/app.py", line 365, in falcon.app.App.__call__ File "/usr/lib/python3.12/site-packages/mailman/rest/lists.py", line 322, in on_post mlist = create_list(**validator(request)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/mailman/app/lifecycle.py", line 102, in create_list call_name(config.mta.incoming).create(mlist) File "/usr/lib/python3.12/site-packages/mailman/mta/postfix.py", line 96, in create self.regenerate() File "/usr/lib/python3.12/site-packages/mailman/mta/postfix.py", line 106, in regenerate with Lock(lock_file): ^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/flufl/lock/_lockfile.py", line 467, in __exit__ self.unlock() File "/usr/lib/python3.12/site-packages/flufl/lock/_lockfile.py", line 417, in unlock raise NotLockedError('Already unlocked') flufl.lock._lockfile.NotLockedError: Already unlocked When I check the lock folder, I have these two files, and I'm wondering if I should delete these two files : -rw-rw---- 2 mailman nogroup 97 Feb 6 2025 master.lck -rw-rw---- 2 mailman nogroup 97 Feb 6 2025 master.lck|mailman-core-deployment-5f59557b66-bkkf4|16|4268829230172994873 Do you have any answer for me ?

Feb. 6, 2025

I'm working on setting up MailMan 3 on an Ubuntu 24.04 LTS server. I've got everything running and working with docker-mailman. Now I'm looking at configuring ARC and am a bit lost. How is ARC configured in a mailman3 with multiple domains? Do I set it up to use the hostname of the server Mailman is running on? Thanks for any assistance, --[Lance]

One-click unsubscribe?
by Jered Floyd Feb. 5, 2025

Feb. 5, 2025

I'm having a lot of problems with GMail delivery due to lack of "one-click unsubscribe" -- however that is quantified, which is not clear. In particular, there is an issue with the fact that Google ignores dots in email addresses. So I have many (MANY!) subscribers who try to use the List-Unsubscribe header target, but because they are subscribed as "idiotsubscriber(a)gmail.com" rather than "idiot.subscriber(a)gmail.com" (which they have since changed their sender to) they get a reject that they are not subscribed. These people are also far too unobservant to read the footer of every message that reads "You are subscribed as idiotsubscriber(a)gmail.com". Is there any way to provide personalized List-Unsubscribe header links, or have Mailman ignore dots in gmail.com addresses... or... anything? I'm finding reported spam percentages in the Google Postmaster Dashboard exceeding 0.1%, which causes massive delivery blocking to GMail-based subscribers. While I would gladly ban everyone who uses gmail, that sadly accounts for about half of the Internet today and would be incredibly unproductive. Thanks, --Jered
