redirecting -bounces replies
by Hirayama, Pat June 26, 2025

June 26, 2025

Greetings, Is it possible to redirect the -bounces alias of a specific list so that it also goes to a person, in addition to the normal bounces processing for that list? In Mailman2, I know that I could do that by modifying the aliases table. I've been poking around in Mailman3, but haven't managed to figure out which container I need to be looking at. And rather than keep spinning, I figured that I'd ask the hive mind, since I'm sure one of you can quickly point me to the correct location. Thanks! -p Pat Hirayama Pronouns: he/him/his Systems Engineer IT | Systems Engineering - Infrastructure Fred Hutch Cancer Center O 206.667.4856 phirayam(a)fredhutch.org<mailto:phirayam@fredhutch.org>

"this held message has been lost"
by Ethan Furman June 10, 2025

June 10, 2025

I have now seen this message on two different occasions. Any ideas on what is happening? Happy to provide additional information if I am told what is needed (and how to get it -- I'm a web moderator for the list without access to the machine it runs on). :) -- ~Ethan~

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

Login confusion
by Markus Grandpré April 22, 2025

April 22, 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 were previously associated with their account (imported from Mailman v2.1) which used a different capitalization. Is there a known configuration option or method within Postorius (or Mailman 3 itself) to normalize or unify account identification, effectively treating email addresses as case-insensitive for account matching? We need a solution that ensures users see their correct list memberships regardless of the capitalization they use when logging in or that was used during the original Mailman 2.1 import. Thank you in advance Markus -- Markus Ludwig Grandpré Universität Konstanz Kommunikations-, Informations-, Medienzentrum (KIM) Abteilung IT-Dienste Forschung und Lehre, B803, Tel: ++49 7531 88 4342

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
