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 I saw that some python packages are outdated an tried this which install all outdated packages in a row: pip list --outdated --format=json | jq '.[].name' | xargs -n1 pip install -U One outdated package was django and this part happened: ------------------------------- vDownloading Django-5.1.4-py3-none-any.whl (8.3 MB) Installing collected packages: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

Django-allauth compatibility (ACCOUNT_AUTHENTICATION_METHOD and ACCOUNT_EMAIL_REQUIRED)
by Jan Eden June 17, 2025

June 17, 2025

Hi, after installing Mailman 3 in a new virtual environment, I ran into the compatibility issues with django-allauth discussed by Andreas Vetter and Mark Sapira on this list in February[1] and in March[2] – WARNINGS: settings.ACCOUNT_AUTHENTICATION_METHOD is deprecated, use: settings.ACCOUNT_LOGIN_METHODS = {'email', 'username'} settings.ACCOUNT_EMAIL_REQUIRED is deprecated, use: settings.ACCOUNT_SIGNUP_FIELDS = ['email*', 'username*', 'password1*', 'password2*'] – and solved them with the additions to /etc/mailman3/settings.py suggested by Mark: del ACCOUNT_AUTHENTICATION_METHOD ACCOUNT_LOGIN_METHODS = {'email', 'username'} del ACCOUNT_EMAIL_REQUIRED ACCOUNT_SIGNUP_FIELDS = ['email*', 'username*', 'password1*', 'password2*'] In the second list thread, Mark linked to the current (patched) version of mailman-web's mailman.py[3], which addresses the deprecation of ACCOUNT_AUTHENTICATION_METHOD, but not of ACCOUNT_EMAIL_REQUIRED. Is there any reason why the patch fixes only one of the two issues? - Jan [1] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [2] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [3] https://gitlab.com/mailman/mailman-web/-/blob/c8b9aef1704b75b1cb6d0c925855a…

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

CPU usage when idle
by roughnecks May 29, 2025

May 29, 2025

Hello, if you look at this graph you'll notice how my VPS "reacted" after mailman3 install. It's a Debian stable host, and I installed packages via apt. I mean, isn't this a bit too much for a software that is idle, because no lists are currently in use? RED is my VPS, the other colors are other machines. Thanks -- roughnecks ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message. Content-Type: image/jpeg Name: raw (1).jpg

Unable to update templates
by Mark May 29, 2025

May 29, 2025

Hi, I'm unable to update the custom welcome template (list:user:notice:welcome) after it's initial creation. When the custom welcome template is created (in Postorius), and a user then subscribed by the list-owner (using mass subscribe), the welcome message is received as expected. However when I update the template, the databases are updated correctly but the Welcome message is still sent with the old template content. mailman.templates mailmanweb.postorius_emailtemplate Additionally, if I delete the template and create a new one the old content still gets sent. I cannot find where this content is written or is being cached. Any clues on tracking this bugbear down gratefully received.

Re: MM broken after proxy migration (Nginx -> Caddy)
by Andreas Kemper May 28, 2025

May 28, 2025

Hi Stephen, thanks for the comprehensive explanations and sorry for initially not answering to the list (I expected this to be the default behaviour). Afterall it turned out that my mailman.db was somehow broken, even though I couldn't find any fishy / strange things in Postorius. Since anyhow just a few lists are hosted on the server and subscriptions for most of them being managed fron another program, I decided to remove MM3 completely and start with a fresh configuration.

Hyperkitty archive: date format in thread overview of list does not honor DATETIME_FORMAT of settings.py
by Christian Schneider May 28, 2025

May 28, 2025

Dear mailman community, with the help of you I was able to set up a new mailman3 environment (a big THANK YOU!!! :-)): OS: Ubuntu 24.04-LTS mailman: GNU Mailman 3.3.10 (Tom Sawyer) Python: 3.12.3 (main, Feb 4 2025, 14:48:35) [GCC 13.3.0] Method: Python Virtual Environment Installation My configuration files are placed in the following directory: /etc/mailman3 - gunicorn.py - mailman.cfg - settings.py The environment is up and running: A list for testing is set up and mails are transfered (and archived) using the test-list - successfully... :-) Looking at the thread overview of the list (in Hyperkitty archives) I realized that the shown date format is unusual (for Germany), like: Do Mai 22, 3:57 nachm. (meaning: Thu May 22, 3:57 p.m.) I would prefer a format like: 22-05-2025 15:57:24 So I tried to reconfigure this setting in settings.py according to this URL: https://docs.mailman3.org/en/latest/config-web.html#configure-postorius-hyp… In settings.py I set DATETIME_FORMAT to 'd-m-Y H:i:s' but the format did not change. (After changing settings.py I initiated a restart of mailman3 and mailmanweb) I also set USE_L10N to False as suggested in Django-Docs: https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-DATETIME_FO… My /etc/mailman3/settings.py is parsed - as far as I can say because changing USE_I18N to false (in /etc/mailman3/settings.py) switches date to English as this is my locales-setting on Ubuntu... Nevertheless the format stays the same (in this case: Thu May 22, 3:57 p.m.) How can I adjust the date format (in the discussion boxes) at the thread overview page (url: https://my-domain.de/archives/list/test-list@lists.my-domain.de/)? Any hint is appreciated! Thank you very much and kind regards Christian
