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…

Trouble Installing Mailman3
by Henry Hartley June 13, 2025

June 13, 2025

I'm having problems installing mailman3 following the instructions on https://docs.mailman3.org/en/latest/install/virtualenv.html Everything goes well until I get to the Installing Mailman Core<https://docs.mailman3.org/en/latest/install/virtualenv.html#installing-mail…> step, which has me do the following in my venv environment: (venv)$ pip install wheel mailman psycopg2-binary Ubuntu 24.04.02 LTS Python 3.12.3 pip version 24.0 First, I was getting problems because my company firewall was blocking outbound traffic. I got that taken care of. Next, I was seeing certificate errors, saying there was a self-signed certificate: WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1000)'))': /simple/wheel/ Could not fetch URL https://pypi.org/simple/wheel/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/wheel/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1000)'))) - skipping When I added --trusted-host pypi.org that error went away but I'm still unable to install anything: (venv) mailman@wz-prd-tpmd-1:~$ pip -v --trusted-host pypi.org install wheel mailman psycopg2-binary Using pip 24.0 from /opt/mailman/venv/lib/python3.12/site-packages/pip (python 3.12) ERROR: Could not find a version that satisfies the requirement wheel (from versions: none) ERROR: No matching distribution found for wheel The same error shows up if I try to install just mailman or psycopg2-binary, except the word "wheel" is replace with whichever package I've requested. I've rerun the apt install of python3-dev and python3-venv to make sure those are present and up to date. Any help you can provide will be greatly appreciated. -- Henry Hartley Westat

mail loops back to myself
by Florian Sukup June 13, 2025

June 13, 2025

Hi, I've spent hours on finding the error but no success. I hope you can help: I am running Debian with older version of mailman3 (3.3.3) and postfix (3.5). Postfix on its own is working fine. I set up mailman, created a site/domain (lists.yyy.com) My hostname is host.xxx.com . My IP has a RDNS entry: reverse.rrr.com . When I send an email to my mailing list mylist(a)lists.yyy.com I receive an error email. The logfile says the following: ... Jun 9 00:23:38 arvak postfix/smtpd[]: connect from host.xxx.com[m.y.i.p] Jun 9 00:23:38 arvak postfix/relay/smtp[]: warning: host reverse.rrr.com[178.251.71.190]:25 greeted me with my own hostname host.xxx.com Jun 9 00:23:38 arvak postfix/relay/smtp[]: warning: host reverse.rrr.com[m.y.i.p]:25 replied to HELO/EHLO with my own hostname host.xxx.com Jun 9 00:23:38 arvak postfix/relay/smtp[]: 094895FADB: to=<mylist(a)lists.yyy.com>, relay=reverse.rrr.com[m.y.i.p]:25, delay=0.06, delays=0.03/0.01/0.02/0, dsn=5.4.6, status=bounced (mail for lists.yyy.com loops back to myself) Jun 9 00:23:38 arvak postfix/smtpd[114119]: disconnect from host.xxx.com[m.y.i.p] ehlo=1 quit=1 commands=2 ... The MX record of lists.yyy.com points to reverse.rrr.com. Not sure if this is the best idea? Can anyone give me a hint where to search for this error? Thanks a lot in advance! Florian.

Full-text searching: why Haystack instead of PostgreSQL?
by admin＠bclug.ca June 10, 2025

June 10, 2025

I've been asked to give a presentation on a recent migration from MMv2 to MMv3 and one of the items in my notes is the question about why Haystack is used for full-text searching instead of PostgreSQL? Can someone shed some light on that decision? Thanks

"to" Headers for Non-Anonymous lists
by Dan Caballero June 10, 2025

June 10, 2025

Hello, At the request of a list owner, we changed the settings on a list to "Anonymous = No" so that list members could see who a message was coming from. It seems a side effect of the setting is that users are now using "reply-to" and some messages are going out to the list addressed in the manner below. "Last Name, First Name via list-name <list-name(a)caltech.edu>" The list owner feels this is confusing and some members may inadvertently email the list when they intend to email the individual. I understand this is likely a client side caching issue since most email clients create an index of contacts based on previously received emails. Aside from reverting back to "Anonymous = Yes", is there any setting we can change at the list level to force the "to" field to persist as the list email address? Thanks in advance for your help. ---- Dan Caballero Systems Administrator Academic Computing Solutions IMSS - Caltech https://imss.caltech.edu

Hi all, I'm just reviewing Stalwart as a many-in-one mailing system. Did anybody yet succeed in plugging mailman into stalwart (the incoming bit seems to be difficult)?

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~

Threads by month dropdown
by Sam Darwin June 7, 2025

June 7, 2025

Hi, After running hyperkitty_import to import thousands of emails from mailman2 (the years 2013-2025) I then ran another import for years 2004-2013 from another mbox file. It was an entirely earlier timeframe, which may be relevant. After the first import, the "Threads by month" dropdown showed 2013-2025. After the second import, the "Threads by month" dropdown showed 2013-2025. That is, 2004-2013 are missing. I have tried various things, including the mailman3-web cron maintenance tasks, waiting a day, and rebooting the server to clear memory. All messages were imported, and can be seen in "All threads". The messages are there. The only problem is the "Threads by month" dropdown. Beyond the dropdown, everything seems fine. Could it be a bug? Should I open an issue? Or, what should I try next? Is there a "refresh all threads by month" specific task? Deleting all archives and importing the older messages first... that worked correctly. It is a large destructive actions though, should that count as the official solution? Detour: While debugging it seemed to be an interesting question whether the mailman3-web periodic cron tasks had been running, and if those tasks affected the hyperkitty import. Referring to "Cron Jobs for Mailman Web" https://docs.mailman3.org/en/latest/install/virtualenv.html#cron-jobs-for-m… Those instructions are not dumping stdout/stderr to a log file, nor rotating the log files. What is your opinion if I sent a pull request that adds "Method 2 - Advanced", and include logging for the crons. Or maybe I am missing something. Is the output of the cron tasks getting logged in your environment?
