As mentioned in the subject, I am getting the following error after every post. Any assistance would be much appreciated: --- ERROR 2025-04-22 11:21:21,356 11617 django.request Internal Server Error: /archives/api/mailman/archive Traceback (most recent call last): File "/opt/mailman/venv/lib/python3.11/site-packages/django/db/models/query.py", line 916, in get_or_create return self.get(**kwargs), False ^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.11/site-packages/django/db/models/query.py", line 637, in get raise self.model.DoesNotExist( hyperkitty.models.sender.Sender.DoesNotExist: Sender matching query does not exist.

Moderator e-mails only going out once a day
by jkoral＠luc.edu April 22, 2025

April 22, 2025

Hi, I have just got done migrating from MM2 to MM3 and the users are experiencing issues with their moderated messages. After the message is sent, the moderator does not know about the message until the next day. I checked the maillogs and all those messages are being sent at the same time around midnight. I also noticed the messages are being sent from user(a)example.com, which I switched in /etc/mailman3/mailman.cfg to a generic e-mail address. Is there a way to change those moderator e-mails to send right away? Does having user(a)example.com in the config affect that? Thank you in advance, Joe

Upgrade docker-mailman to v0.5.2
by Christopher April 21, 2025

April 21, 2025

Hi Abhilash, I checkout the v0.5.2 for testing my upgrade from 0.4.6 and noticed, that the docker-image-version is still set to 0.4 in docker-compose.yaml. Is there any reason for it or should it be set to 0.5? I´m still using my good old mariadb. I did not find any upgrade-informations about breaking-changes. Do you have any experience with migrating from 0.4.6 to 0.5.2 on mariadb? Best regards Chrclaus

posting bounced with 501 Message has defects
by Hitashi mancho April 21, 2025

April 21, 2025

Dear All, One of our users posted an email using a Bluemail Desktop client on one of the mailing lists. This email bounced with the reason "501 Message has defects". However, it gets accepted if the same user posts the same email on the same mailing list using Webmail (RoundCube) or Thunderbird. There is nothing in mailman.log and bounce.log, even in debug mode. Following is the SMTP log for the same email posting and the email header. Any guidance in debugging this will be highly appreciated.

Setup Question: Disk-Layout (Migrating from Mailman 2.1)
by christian.schneider＠tu-dortmund.de April 21, 2025

April 21, 2025

Hello, actually I am running the latest available Mailman-2 Version on Ubuntu 20.04! Now it is really time to move on! :-) I want to set up a new server (Ubuntu-24.04) and install Mailman-3 with the Virtualenv setup method: https://docs.mailman3.org/en/latest/install/virtualenv.html As I know from my old Mailman-2.1 the archives could get quite big... ;-) So it seems very important to provide enough (expandable) disk space at the right place. (I plan to use a seperate partition with LVM for the path in question) But I could find no information about the location where hyperkitty stores the archives on an Ubuntu-/Linux-system. I assume the archives are stored underneath "/var/..." this is only a guess. But is this guess right? Another question is: How much space do I have to plan (roughly) for the "/opt"-partition for the mailman install if the archives are stored under "/var/..."? Any guidance ist very much appreciated! Thank you very much Chris

moving from sqlite3 to postgresql
by Michael Richardson April 20, 2025

April 20, 2025

Hi, I installed mailman3 a few years ago on lists.sandelman.ca aka lists.tcpdump.org. My upgrade was in part a response to the HTTP based attacks that used the signup form on mailman2 to attack people via SMTP with DOS. I know the IETF mailman2 install {now gone} had some kind of delay implemented in the web form before you could submit. I didn't understand why. I installed via debian packages, and I'd really prefer to stay with that. (Not what many maintainers would say, I know. Essential that it work if mailman3 is going to take over) There were problems, probably with the hyperkitty integration with subsequent updates seemed to solve. I installed with sqlite3, since it seemed if all work was going to go through the mailman3 daemon, that it would handle all the concurrency issues. This has not been the case. I get weekly complaints about the database being locked. Sometimes this goes way on it's own, but sometimes it does not. A good way to tickle this is to go the web interface, go to a list with 200 held messages, and then having told it to show me 100+ messages per page, to then tell it to discard them all. So slow. Before I realized what was going on, I'd open multiple tabs to try to make this concurrent. So I tried to switch last week from sqlite3 to postgresql. I used pgloader with a configuration file attached below. This seemed easier than a sqlite3 dump/psql, as the SQL requires some massaging that seeemed to require more brainpower than I had at the time. I then edited /etc/mailman3/mailman.cfg to suit. I had set up the postgresql database under the "list" owner, so unix-domain socket permissions, and restarted. I then saw some errors: lists not found! I visited the web interface. NO LISTS. DAMN. I put it back. I haven't figured out what went wrong yet. I will clone the VM and try again. I will report whatever I find here. === load database from '/var/lib/mailman3/mailman.db' into postgresql:///mailman3 with include drop, create tables, create indexes, reset sequences set work_mem to '16MB', maintenance_work_mem to '512 MB'; === ps: I'd pay some $$ money for email support consulting.

Disabling "delete account" option
by Hitashi mancho April 19, 2025

April 19, 2025

Dear all, Recently, I have migrated from Mailman2 to Mailman3 GNU Mailman 3.3.10 (Tom Sawyer) Python 3.11.9 Some of the list users logged into Postorius and went to profile settings. Over there, they found an option "Delete Account". Without any discussion, they deleted their account and all their list membership. How can we prevent this from happening? Is it possible to disable this "Delete Account" option, or can we add some admin approval? Regards, Hitachi. ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Do you struggle with message rejected. AUP#CDRBL while using mailman with your ISP email relay?
by Michael Richardson April 18, 2025

I'm impressed by Philip Bondi's use of mailman[23] for home financial automation. ("Take off Eh!") ... It seems like a ticketing system would be a better system for such a use... maybe the IETF SML WG will further help with this.. (I find most Canadian financial institutions are so far behind the curve) I think that your email is hosted by hostedemail.com? I'm guessing that "eshop" is the mailbox you use for these common notices, and maybe you retrieve that into your mailman3 with fetchmail or something? Or does your ISP turn around and SMTP to you directly? Is it your MTA, their MTA, or mailman that is doing the rejection? My problem, on lists.sandelman.ca aka lists.tcpdump.org, is messages that appear to have been processed by my MTA (according to postfix logs), but which are never delivered, nor held. Lost somewhere in mailman3 queue. Sometimes they show up after a host reboot.

Do you struggle with message rejected. AUP#CDRBL while using mailman with your ISP email relay?
by Philip Bondi April 17, 2025

April 17, 2025

Hello to all: mailman3 is phenomenal upgrade from mailman2. Very nice. Thank you to the team. In our family, we use mailman to provide redundancy on important financial emails. In this manner, emails from banks, government, ecommerce or other important providers are distributed to multiple family members. And we can ask family members if they paid the credit card bill, received their delivery, saw their tax liability or refund notification, etc. Does anyone else use mailman for such a purpose? Do you struggle with "message rejected. AUP#CDRBL" while using mailman with your ISP email relay? For example, when receiving email from a Bank or the Government of Canada on a mailman2 list, sometimes my ISP would not relay the email and I would get message rejected. AUP#CDRBL On mailman2, I mitigated by stripping headers, wrapping message and DKIM signing. Here is a mailman2 message that is stripped, wrapped and signed. https://freeimage.host/i/30O5EXe Do you have this problem with your ISP with certain senders? What are your mitigation strategies on mailman3?

makemigrations --merge error after Debian upgrade
by Chupin Maxime April 16, 2025

April 16, 2025

Hi, I upgraded my debian version, and since, it seems that I have a problem. I tried `mailman-web migrate` (and `mailman-web collectstatic` etc.) and I get the error message: ``` CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0010_auto_20220618_2315, 0014_schedule_cluster in django_q; 0014_auto_20220618_2315, 0018_alter_emailtemplate_language in postorius). To fix them run 'python manage.py makemigrations --merge' ``` So I tried `mailman-web makemigrations --merge` that ended with ``` PermissionError: [Errno 13] Permission denied: '/usr/lib/python3/dist-packages/postorius/migrations/0019_merge_20240930_1159.py' ``` There is no such a file in the migration directory. Any idea ? Thanks in advance, All the best Maxime Chupin
