Recently active discussions - Hyperkitty
by Sam Darwin June 5, 2025

June 5, 2025

Hi, Sometimes not sure if it's preferable to open a gitlab issue, or chat on the mailing list. I have run a large archive import into mailman3/hyperkitty. After that's done, waited a day, for scheduled cron jobs to complete. In "All Threads", all the email archives are present. The import worked. In "RECENTLY ACTIVE DISCUSSIONS" on the main page, it says: RECENTLY ACTIVE DISCUSSIONS No discussions this month (yet). Nothing there. That means if I direct users to visit the site, the page, it appears empty. That's too bad. :-) It should display recent emails. What would affect this feature during an archive import? Is it a problem with the import script itself, or with a scheduled cron job, or something else? Would you expect "Recently active discussions" be empty when very recent archives do exist? Thanks, Sam

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

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

Find a smtp server to send out emails
by Leon March 12, 2025

March 12, 2025

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman3. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. -- Best wishes, Leon

Moderation of held emails vs. spam
by David Krantz March 11, 2025

March 11, 2025

Hi, I now run Mailman 3.3.1, installed from pip. Is there now any way to prevent Mailman from forwarding the contents of the held message when notifying moderators of held messages? In my case these messages often are spam messages and if the entire contents are forwarded it triggers spam handling in the recipient address(es) which over time risks classifying all moderation emails as spam or even classifying the list domain or server as a spam source. Even my own outgoing filter classifies it as spam, which I will fix. I currently run rspamd for spam filtering, graylisting and DKIM and ARC verification/signing. Someone on this recommended it, thank you for that as it removes the need for other milters. I guess that this would be a simple change to make as a kludge but a proper implementation as a setting would be a lot better. I'd like it as a global setting but that might be too coarse. Cheers // David

Issues with a DMARC record leading to message being shunted

Something with DMARC and tags. So I checked the DMARC record for the sending domain somenet.org. It is "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;mailto:postmaster@somenet.org;ri=3600;fo=1;" which is syntactically incorrect. The extra ";mailto:postmaster@somenet.org" is wrong, I guess the tag "ruf=" is missing here! It should probably read "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;ruf=mailto:postmaster@somenet.org;ri=3600;fo=1;" So, should mm3 somehow "catch" this error somehow? According to the DMARC specs, an syntactically incorrect DMARC record should be ignored / handled as if none were present. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

How To Install Mailman 3 on Debian 10 (Complete Guide)
by Brian Carpenter Feb. 25, 2025

Feb. 25, 2025

I have finished my how-to install Mailman 3 on Debian 10 completed to the point where you can use it to get a fully functional Mailman 3 environment up and running. This is a comprehensive guide that walks you through installing EVERYTHING (currently!) that Mailman 3 needs to run. It also makes updating Mailman 3/Postorius/Hyperkitty very easy. I have not added the update directions yet but will very soon. I also plan on adding a section on setting up DKIM and Xapian with Mailman 3. I hope this helps those who wish to get a Mailman 3 server up and running quickly and brings a sense of sanity to the confusion regarding the various documentation out there concerning the installation of Mailman 3/Postorius/Hyperkitty. I intend to add a How-to for Ubuntu 20 at some point. Without further ado: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 I am sure the above guide can use improvements. Feel free to contact me off-list to point out mistakes/improvements, etc. -- Brian Carpenter Harmonylists.com Emwd.com

Hi As a moderator I receive an email each day for "Held Unsubscriptions" for a subscriber that was unsubscribed by the Owner sometime ago (using "Mass operations"). +++++++++++++++++++++++++++++++ The listname(a)domain.com list has 1 moderation requests waiting. Held Unsubscriptions: User: bart(a)example.com Please attend to this at your earliest convenience. +++++++++++++++++++++++++++++++ There is nothing showing under "Subscription requests > Pending approval". Could anyone tell me how I can stop these email notifications? I have access to the mailman shell and the databases. Thanks, Mark

Re: mail stuck in "out" queue

So our mailman got stuck again, but I did follow your advise.

SIGINT killed the process allright, but it didn't auto-respawn. I ended up spawning it with: /usr/local/bin/python /usr/local/bin/runner --runner=out:0:1 -C /etc/mailman.cfg but soon realized it doesn't go to background nicely so I've nohup'ed it in the end. but it did solve my problem. -- Sr System and DevOps Engineer SoM IRT
