after last upgrade I've got a CSRF failed verification
by Guillermo Hernandez (Oldno7) Sept. 5, 2025

Sept. 5, 2025

I did upgrade one of my mailman3 server after Abhilasj announcement: "I am pleased to announce several new releases for GNU Mailman project. 1. Mailman Core 3.3.6 1 <https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/NEWS.…> 2. Postorius 1.3.7 2 <https://docs.mailman3.org/projects/postorius/en/latest/news.html#section-2> 3. Hyperkitty 1.3.6 [3] 4. Mailmanclient 3.3.4 [4] 5. Django-mailman3 1.3.8 [5]" I did it via pip and all seems to be working, but when I try to discard or accept any message via postorius it shows a Forbidden 403 error CSRF verification failed. In my settings.py I have commented out these variables: # Other security settings # SECURE_SSL_REDIRECT = True # If you set SECURE_SSL_REDIRECT to True, make sure the SECURE_REDIRECT_EXEMPT # contains at least this line: # SECURE_REDIRECT_EXEMPT = [ # "archives/api/mailman/.*", # Request from Mailman. # ] # SESSION_COOKIE_SECURE = True # SECURE_CONTENT_TYPE_NOSNIFF = True # SECURE_BROWSER_XSS_FILTER = True # CSRF_COOKIE_SECURE = True # CSRF_COOKIE_HTTPONLY = True # X_FRAME_OPTIONS = 'DENY' I've been messing with them whith no results. It's like it lacked some value in some template... Can someone, please, point me in the right direction? Thanks in advance -- ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Missing Base64 encoding from control message reply

Dear all, I have a setup with GNU Mailman 3.3.8 where a user tried to subscribe. When replying to the "confirm" message, the user received a completely garbled response, like so: N�z˥��ʋ�zf��&��j��u�[zZ0:��v��,j�z֢��k�e�0 4Dҹ��r�^b��r�ߊ��*'��yם��{ax�L�X��0:��v��,j�z֢��k�d�m�-��zz�rn��l]y+��-E�( �^N��'��M��tۯ��Mz��^i��׮��}�o�\ӷ��6sN�zf��ݮ��r��z˥��b�{h��݉��f�r�ne== (The line above contains numerous unprintable characters, etc.) The user then forwarded the .eml file to me, which clearly shows the contents of the mail as plain text while being announced as base64 (Content-Transfer-Encoding: base64): START OF EML Return-Path: <LISTNAME-bounces(a)lists.DOMAIN.COM> Received: from DOMAIN.COM ([144.76.173.241]) by mx-ha.USERDOMAIN.NET (mx06 [IP]) with ESMTPS (Nemesis) id 1M27WV-1qhRFk39Sr-00AQcR for <USER(a)USERDOMAIN.NET>; Thu, 21 Sep 2023 19:10:37 +0200 Received: from localhost (localhost.localdomain [127.0.0.1]) by DOMAIN.COM (Postfix) with ESMTP id 4058B3BD5EEF for <USER(a)USERDOMAIN.NET>; Thu, 21 Sep 2023 19:10:37 +0200 (CEST) Received: from DOMAIN.COM ([127.0.0.1]) by localhost (DOMAIN.COM [127.0.0.1]) (amavis, port 10024) with ESMTP id x0ngnlRnGraH for <USER(a)USERDOMAIN.NET>; Thu, 21 Sep 2023 19:10:37 +0200 (CEST) Received: from [IP] (unknown [IP]) by DOMAIN.COM (Postfix) with ESMTP id DC8603BD5EEE for <USER(a)USERDOMAIN.NET>; Thu, 21 Sep 2023 19:10:36 +0200 (CEST) Subject: =?utf-8?q?The_results_of_your_email_commands?= From: LISTNAME-bounces(a)lists.DOMAIN.COM To: USER(a)USERDOMAIN.NET Content-Transfer-Encoding: base64 MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Message-ID: <169531623416.29.5762261018677554285@mailman-core> Date: Thu, 21 Sep 2023 17:10:34 +0000 Precedence: bulk X-Mailman-Version: 3.3.8 List-Id: <LISTNAME.lists.DOMAIN.COM> List-Help: <mailto:LISTNAME-request@lists.DOMAIN.COM?subject=help> List-Owner: <mailto:LISTNAME-owner@lists.DOMAIN.COM> List-Subscribe: <mailto:LISTNAME-join@lists.DOMAIN.COM> List-Unsubscribe: <mailto:LISTNAME-leave@lists.DOMAIN.COM> Envelope-To: <USER(a)USERDOMAIN.NET> X-Spam-Flag: NO The results of your email command are provided below. - Original message details: From: USER <USER(a)USERDOMAIN.NET> Subject: Re: Your confirmation is needed to join the LISTNAME(a)lists.DOMAIN.COM mailing list.

Upgrading other python packages than the mailman ones in a venv results in dependency conflicts
by Ulf R. July 29, 2025

July 29, 2025

Hello, I know this should be the way to upgrade: https://docs.mailman3.org/en/latest/upgrade-guide.html I have 3.3.10 installed. I saw that some python packages are outdated an tried this which install all outdated packages in a row: pip list --outdated --format=json | jq '.[].name' | xargs -n1 pip install -U One outdated package was django and this part happened: ------------------------------- vDownloading Django-5.1.4-py3-none-any.whl (8.3 MB) Installing collected packages: Django Attempting uninstall: Django Found existing installation: Django 4.2.16 Uninstalling Django-4.2.16: Successfully uninstalled Django-4.2.16 ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. hyperkitty 1.3.12 requires django<5.1,>=4.2, but you have django 5.1.4 which is incompatible. mailman-web 0.0.9 requires django<4.3,>=4.0, but you have django 5.1.4 which is incompatible. postorius 1.3.13 requires django<5.1,>=4.2, but you have django 5.1.4 which is incompatible. django-mailman3 1.3.15 requires django<5.1,>=4.2, but you have django 5.1.4 which is incompatible. Successfully installed Django-5.1.4 ------------------------------- So I made a roll back. Is this really the only secure way to update the venv?: pip install -U mailman postorius django-mailman3 hyperkitty mailman-web May be yes and I have to ignore the rest? ;-) Thank you und regards

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

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
