Heads up: settings.ACCOUNT_AUTHENTICATION_METHOD is deprecated
by Andreas Vetter Aug. 1, 2025

Aug. 1, 2025

Hello, I have a venv installation of: mailman postorius django-mailman3 hyperkitty mailman-web I just did a pip install -U --upgrade-strategy eager When running mailman-web runjobs -l I get the following Warning: System check identified some issues: WARNINGS: ?: settings.ACCOUNT_AUTHENTICATION_METHOD is deprecated, use: settings.ACCOUNT_LOGIN_METHODS = {'email', 'username'} I guess this is from allauth (version django-allauth-65.4.1). Changing ACCOUNT_AUTHENTICATION_METHOD to ACCOUNT_LOGIN_METHODS in /etc/mailman3/settings.py is not enough. One has to edit venv/lib/python3.11/site-packages/mailman_web/settings/mailman.py -- Mit freundlichen Gruessen, Andreas Vetter

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 I saw that some python packages are outdated an tried this which install all outdated packages in a row: pip list --outdated --format=json | jq '.[].name' | xargs -n1 pip install -U One outdated package was django and this part happened: ------------------------------- vDownloading Django-5.1.4-py3-none-any.whl (8.3 MB) Installing collected packages: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

Enforcing SSO and subscription options
by dlb-ml＠anl.gov July 21, 2025

July 21, 2025

Contrary to the messages I found in the archive, rather trying to delete or remove the social login portion of the sign in page, I'm looking to see if there's any way to isolate the third-party login section and prevent local account sign in and sign up. This way, we can ensure that the people within our organization are using a stronger auth method that prioritizes MFA, rather than just username/password. To do this, our plan is to block signups using "ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter'" and to remove the portions of the login template such that the username/password/forgot password fields are removed, leaving just the button to our SSO instance. I'm anticipating that this should be sufficient to block username/password sign ins, and is resistant to page manipulation due to CSRF tokens, but I wanted to ask to see if there was a better way, like an official configuration (which I have not found yet). I did see that there is the SOCALACCOUNT_ONLY option, as provided by allauth (https://docs.allauth.org/en/latest/socialaccount/configuration.html) but that broke any attempt to display the sign in page, and I'm assuming is not supported with the current version of MM3. Is my plan to modify the templates viable? Additionally, because external users would not have access to their own dashboards within the web UI, and since we are planning on disabling anonymous subscriptions with "SHOW_ANONYMOUS_SUBSCRIBE_FORM=False", the only two viable ways to subscribe to a list for them would be: 1) Send a request directly to the list owner or a superadmin to subscribe/unsubscribe the address 2) Allow email commands to subcribe/unsubscribe users (i.e. $LISTNAME-join@$DOMAIN) Given the discussions on disabling the anonymous subscription form, are the email commands a less spam-susceptible solution or are they just as vulnerable as the form? Thanks

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>

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

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

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
