Displaying addresses in emails from a Mailman 3 installation
by Steve Brown July 3, 2025

July 3, 2025

In a list I administer, the From line in an incoming email shows [Poster's Name] via [List Name] <address for posting a reply> . I use Outlook as my client, but at least some other clients behave similarly. However, I have at least one subscriber who uses Mozilla's Thunderbird as his client, and periodically the format changes to something else, most recently to just [List Name <address for posting a reply> . I suspect this occurs from some combination of the way Thunderbird parses the header and the way it populates some kind of address book that makes autofill work, but I'm not sure. Is this a known problem? Is there an easy fix that will be stable? In the past, putting an association in his address book and removing others worked, but it didn't hold and he is frustrated.

Caching problem with templates
by Mark June 29, 2025

June 29, 2025

Caching problem with templates. GNU Mailman 3.3.10 Python 3.11.2 Postorius Version 1.3.13 Venv installation per docs Hi All, A footer template is created and initially it works as expected. Editing the footer template sees the new content written to the database, In addition to viewing the edited content in the database, the new template can also be viewed in Lynx on localhost at: http://localhost:8000/mailman3/api/templates/list/<IDENTIFIER>/list:member:regular:footer The problem is that the original template is being cached somewhere and the old footer persists in new emails. In trying to get the edited footer to show in the emails I've restarted mailman3/mailmanweb, rebooted the server - but no joy. Any advice on how to flush the cache or hammer this gremlin greatly appreciated. Thanks, Mark

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>

Change the default value for the General Archive Policy
by Markus Grandpré June 26, 2025

June 26, 2025

Dear list, currently, when I create a new mailing list with MM3 the value for "Archive policy" is always set to "Public archives". I'd like to change the default value for "Archive policy" to "Do not archive this list". How can I do this? In Debian 12 I find in </usr/lib/python3/dist-packages/postorius/forms/list_forms.py>: mlist_properties = ['archivers'] archive_policy_choices = ( ('public', _('Public archives')), ('private', _('Private archives')), ('never', _('Do not archive this list')), ) archive_rendering_mode_choices = ( ('text', _('Plain text')), ('markdown', _('Markdown text')), ) archive_policy = forms.ChoiceField( choices=archive_policy_choices, widget=forms.RadioSelect, label=_('Archive policy'), help_text=_('Policy for archiving messages for this list'), ) but have no idea how to change the settings here. Your help is very appreciated.

Block members from sending cc's and bcc's
by Cathryn McGuire June 23, 2025

June 23, 2025

Hi everyone, Using Mailman 3 with Affinity web interface and we want to stop our members from sending to cc: or bcc: We've found the Header Filter and cc and bcc appear in it. Tried to configure it to "hold for moderation," but it hasn't worked. Partly because we don't understand what to put in the Pattern input box. I put in cc: because it requires something. Can anyone advise? Cheers, Cathryn

Creating users via RestAPI / User-Management - a bunch of questions
by Christian Schneider June 23, 2025

June 23, 2025

Dear Mark and companions, somehow I can not cope with the user management... (I am running a venv-installation, latest stable versions) I read this manual: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/… and played with the RestAPI calls... I know about the fine grained differences between user and member, admin/owner, superuser... and about the two user databases in PostgreSQL and Django-Framework. What I stumble upon is the RestAPI calls to create a "working" user (with the ability to login via WebUI). When I follow the manual (from the url above) I create a user (including password) that appears in the PostgreSQL database. (And this user is visible on the User-URL (https://example.com/mailman3/users)) Even when I (via WebUI) set the user as "approved" this user is not able to log in... I assume this restriction is in accordance to the fact that there is not equivalent Django user. (There was a mail in the archive of the MM3 user group...stating that one has to use the Django RestAPI to create the appropriate user) When I create the user using the WebUI (https://example.com/accounts/signup/?next=/mailman3/lists/) the new user is created in the right (complete) way...appearing in the PostgreSQL database and as a user in Django. How is this sync between the two databases realized? (The Django user also has the correct status (no staff status / no superuser status / just active status) how is this realized?) As I am not very familiar with python programming (I know Perl/Java/C++ and have an (maybe outdated) concept of OOP), is there a quick way to implement this kind of sync by copying the register logic from mailman's python action script for registering? Other questions: Will there be a create_admin_user-script that is callable via CLI (like createsuperuser or create_list)? (This script ought create a user in PostgreSQL and as Django user) How will a social account provider (like oidc) linkage (in Django) fit in this concept? Will oidc-accounts be copied to the Django's user database (or PostgreSQL db) or is it an on-the-fly check against the oidc-provider? (I assume second option) What are the status-flags (staff status/superuser status/active status) of the linked oidc-accounts? (Can I specify the status flags?) A conceptual thought: When "user1" (with email user1(a)example.com) is known to django via oidc linkage and I create "user1" (also with email user1(a)example.com) via RestAPI calls (following the url https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/…) do I have a "complete" user then? I mean a user who is able to login and who can be assigned to a list as admin (e.g.) (In this case I would not have to care about the Django user database... ;-)) Thank you for some clarifying hints... :-) Chris

two signatures on sent mail?
by STR June 20, 2025

June 20, 2025

Hi, I am a very non-savvy mailman list user. I am trying to set up a list via cPanel but when I send emails there are two signatures. One is my usual signature and the other, below, is appended by Mailman and includes an http link to a non-existent page on my website. How do I strip the auto signature, just leaving my own? I use Mailman via cPanel on two separate hosting accounts. One works fine and this new one attaches the list address. I can't see what I did differently with the first! any help gratefully received Kate

footer template priority
by Sam Darwin June 20, 2025

June 20, 2025

It seems templates can be configured in the filesystem or via postorius. When I place a footer template in the filesystem it worked fine. Then without adjusting any configuration, without removing that, I tried to use the postorius control panel to add a footer template, which ends up in the database, both the core and web databases. But emails stop getting sent out. Emails were posted into Hyperkitty, but not mailed out via postfix. Whatever system logs I have access to, I have checked. There are no apparent errors anyplace. Perhaps I didn't look in the right places. The problematic email arrives, is posted to Hyperkitty, but isn't emailed out to subscribers. As if the template broke something. I remove the template from the postorius UI. Those queued emails are instantly sent! The template said "test content". No variables. I checked on the server for "queued emails" and did not find those either, in postfix or mailman. Mysterious. The phenomenon is repeatable on this server. Add a footer template, emails stop.

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.

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 ...

"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

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?

What is the best practice creating lists triggered by a another / second system?
by Christian Schneider June 6, 2025

June 6, 2025

Dear MM-Users, after reading a lot in the projects documentation of mailman3 I am not sure how to set up a "connection" between another system/server (running a self-service portal for our users) and the mailman3 server (venv-installation) for creating lists (giving a list owner's email address and a customized list style, given by name). On our old mailman-2.1 instance I used an ssh-tunnel and triggered the newlist-command with appropriate parameters. This seems a little bit outdated to me - nowadays... ;-) So I read about the rest api of mailman3 and thought, I might give it a go... On the other hand the rest api should not be exposed externally (localhost-only) as said here: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… Running an nginx reverse proxy (and a firewall for the complete subnet) I am able to give dedicated access to the api but nevertheless I have no good feeling going this way... So my question is: What would be the best way to trigger creation of lists using a second system? Thank you for any suggestions! Chris

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

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)

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

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

Place holders
by Mark May 28, 2025

May 28, 2025

Hi, The place holders listed as available on the "Add new template" page are: $hyperkitty_url $listname $list_id: $display_name $short_listname: $domain $info $request_email $owner_email $site_email $language The only one that seems to sort of work on my template is $list_id - which displays as "testlist". (I was expecting to see "testlist(a)example.com"). The others just get displayed as a variable. Eg. $owner_email Have I missed a setting somewhere?

MM broken after proxy migration (Nginx -> Caddy)
by Andreas Kemper May 27, 2025

May 27, 2025

Hi, I've been running MM 3 for quite some time, with a couple of lists including members managed via the REST-API from an external program. After some issues with LetsEncrypt certificates, I migrated the HTTPs proxy from previous Nginx now to Caddy with the following Caddyfile: https://listen.dlc-aachen.de { header Strict-Transport-Security max-age=31536000; # Disable access to archive and registration redir /hyperkitty* https://listen.dlc-aachen.de redir /accounts/signup* https://listen.dlc-aachen.de reverse_proxy localhost:8000 { header_up X-Forwarded-Proto {scheme} header_up X-Forwarded-Host {host} } handle_path /static/* { file_server { root /var/lib/mailman3/web/static } } } Following this change, list continued operation as usual, but after a few days it seemed to be attacked via it's GUI, according to the attached Django error message. Since then mailman doesn't send out anymore mails and I have a persistent master.lck file. Furthermore, during mailman start smtp.log always shows a "Connection lost during _handle_client()". I guess the connection loss is related to the master.lck file, hence how can I get rid of it / "reset" mailman? In addion, should I include further directives in my Caddyfile in order to protect mailman from coming attacks? Thx a lot Andreas

Django: An error occurred while processing your request.
by Florian Sukup May 27, 2025

May 27, 2025

Hi, I running Debian bookworm and have installed mailman3-full (+ postfix). I am new to mailman3 (using mailman2 now) and about exploring how to migrate. I had 3 sites or domains: example.com and two real ones. When I received emails from postorius, then it came from example.com which is nonsense as I worked with the real lists. So I deleted example.com. When I call https://.../mailman3/admin or any of the lists, the result is: Server error An error occurred while processing your request. How can I get out of it? This is only a test environment, so no heart attack. Thank you for any help. Florian.

Moderation -- implicit destination behavior
by Steve Bachinsky May 24, 2025

May 24, 2025

Hi. We have noticed some posts being held for moderation (even though user has permission to post to list) and Mailman reports: moderation_reasons: ['Message has implicit destination’] The lists are configured for “require_explicit_destination”. However, the email address of the list is clearly in the CC: header of the email (no alias or subdomain). Is there some other reason why Mailman would hold an email for moderation with the reason of “implicit destination”? This moderation is not consistent for same list and poster. The emails come from a large domain with multiple load-balancing email servers. I suspect that it may be something with one or more of the servers being misconfigured, but unable to see anything obvious from the headers and confused why Mailman states the reason to be implicit destination when that does not seem to be the cause. Thanks, Steve

Execute assorted Mailman functions via Mailman shell terminal
by Andy Matthews May 15, 2025

May 15, 2025

When my company migrated from MM2 to MM3, they discovered there were things that didn't work as expected (don't get me started). So they developed a set of Python functions which allowed then to fill in the missing functionality. However, they've discovered that some of those functions either never worked properly, or no longer work. For example, ``` def list_nonmembers(mlist): for accepted in mlist.accept_these_nonmembers: print("Accepted: ",accepted) for held in mlist.hold_these_nonmembers: print("Held: ",held) ``` They're run by shelling into the machine which hosts mailman and executed like so (where scripts is `scripts.py`) ``` sudo -iu mailman mailman shell -l MAILING_LIST_ID --run scripts.list_nonmembers ``` I'm recommending that we install Postorius, as I suspect many of the functions they've written are already present in that UI, but it's not as simple as that. Instead they're wanting a handful of these functions (including the one listed above) replaced sooner than we could get Postorius up and running. I've gotten this far: ``` from mailman.interfaces.listmanager import IListManager from zope.component import getUtility mylist_id = 'bravo-open1(a)tena-sda.org' list_manager = getUtility(IListManager) mylist = list_manager.get(mylist_id) ``` The mylist variable is of type `mailman.model.mailinglist.MailingList`, and includes an Attributes for nonmembers: ``` mylist.nonmembers <mailman.model.roster.NonmemberRoster object at 0x7ffffa3e65b0> ``` But this nonmembers property doesn't output any users/addresses when printed, and throws a TypeError when I try to iterate over it: ``` Traceback (most recent call last): File "<console>", line 1, in <module> TypeError: 'NonmemberRoster' object is not iterable ``` So, given a mailing list instance, retrieved via `list_manager.get(mylist_id)`, how would I go about printing all nonmembers and their current roles in a list (held, accepted, etc.)? Alternately, is there a different question I should be asking in order to retrieve that information?

Mass subscription and Delivery mode/status
by Andreas Vetter May 14, 2025

May 14, 2025

Hello all, we run a venv installation of "mailman postorius django-mailman3 hyperkitty mailman-web". When I mass subscribe (pre-verified) a new mail address into a list, the Delivery mode appears as Regular in /mailman3/lists/somelist.example.com/members/member/ That is what I expect. When I click on the new mail address from there, i.e. mailman3/lists/somelist.example.com/members/options/eimer@mail.org?role=mem… the Delivery status is ----- instead of Enabled and the Delivery mode is ----- instead of Regular. In fact, all yes/no radio buttons are unset. This is unexpected. What does ----- mean in that case? Is it unset and some default (from the list?) is used? After thinking another round about it: Is the view mailman3/lists/somelist.example.com/members/options/eimer@mail.org?role=mem… only filled with values, when somebody (member, list owner or admin) actively set values and unfilled otherwise? -- Mit freundlichen Gruessen, Andreas Vetter

configuring postfix local recipient table
by Alexander Inzinger-Zrock May 5, 2025

May 5, 2025

**System Key Data** OS: Debian 12 mailman: GNU Mailman 3.3.10 (Tom Sawyer) Python: Python 3.11.2 (main, Nov 30 2024, 21:22:50) [GCC 12.2.0] Method: Python Virtual Environment Installation Ahoi, i am trying to configure a mailman3 instance to replace a mailman2 installation (both on different hosts). The mm3 instance is actually not reachable (Incoming) but can send (Outgoing), as is the desired state to be (we intend to swap IPs during change of systems). A. Verify Incoming To verify that emails send to the MTA (postfix) get properly handled and handed over to the mm3-instance i tried to substitute incoming email by a) swaks utility [1] (fail) b) telnet utility [2] (fail) c) command ''mailman inject'' [3] (success) With c) i copied a former generate testmail-file to the mm3-host and injected it directly to my testlist (leaving out the MTA). With a) and b) i tried to hand over a testmail via CLI to the MTA (postfix) what resulted in the error: "Recipient address rejected: User unknown in local recipient table" B. /etc/postfix/main.cfg A search in mailman-users(a)mailman3.org archives [4] pointed me to the configuration of postfix as MTA [5], especially settings with the 'local_recipients_maps' parameter that should be set like [5]: local_recipient_maps = proxy:unix:passwd.byname $alias_maps hash:/path-to-mailman/var/data/postfix_lmtp what i did / already had done. C. aliasing, restarting services and test without , I then restarted postfix, rebuilt the postfix aliases (command ''newaliases'') and rebuilt the mailman aliases (command ''mailman aliases''), even tried with space-separation instead of coma-separation [6], testet again with same result. D. empty /opt/mailman/mm/var/data/postfix_lmtp and then i just found out that my postfix_lmpt file was empty (that i believe to be the the place from where the hastables take their input). Questions: 1. could somebody suggest a way, an entry should occur in postfix_lmtp? 2. What would be the appropriate order to manually generate aliases? first: postfix-command ''newaliases'' and second: mailman-command ''mailman aliases'' or reverse? 3. finding traces [7] of a file called postfix.cfg i can't find it (anymore) in the official installation instructions. Is that file (still?) necessary regarding: 3.1 parameter for default lookup table type 3.2 pointing to command ''postmap'' 4. to what user should the command ''postmap'' be available [8]? Any pointer to manuals or examples i may have missed or ideas on any of those 4 questions would be greatly appreciated. lg alexander Sources: [1] swaks utility https://jetmore.org/john/code/swaks/ [2] telnet utility https://de.wikipedia.org/wiki/Telnet [3] command ''mailman inject'' https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/commands/d… [4] search mailman-users(a)mailman3.org archives 'user unknown in local recipient table' https://lists.mailman3.org/archives/search?q=user+unknown+in+local+recipien… [5] docs mm3: 'Hooking up your mail server' https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h… [6] docs postfix: local_recipient_maps https://www.postfix.org/postconf.5.html#local_recipient_maps [7] traces of postfix.cfg + https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… + https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/NEWS.… [8] docs mm3: transport maps (regarding command ''postmap'') https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h…

Log Owner/Moderator actions ban address matching.
by Hitashi mancho May 1, 2025

May 1, 2025

Dear All, In Mailman 3, is there any way we can log the Owner/Moderator actions like moderator "x" approved the posting on list(a)example.com? Also, I have configured some local ban lists and some global ban lists as per my organization's policy. In my setup, I observed that when someone from the ban list posts to the list, that posting goes into a blackhole without leaving any trace. I may have made some configuration mistakes, but can we log the ban list matching or generate a notification if some postings match the ban list? Regards, Hitachi.

Mailman not starting after restoring from snapshot
by zachr＠mta.ca April 28, 2025

April 28, 2025

I made a snapshot of my mailman3 VM before running a script to modify a bunch of lists. I stupidly did not turn the VM off before I made the snapshot, so Im almost certain this is a corrupted DB problem from doing a snapshot restore. The issue is now that the mailman service will not start automatically. Im able to get to the web interface but I see the error "Mailman REST API not available. Please start Mailman core." I can su to the mailman user and run 'mailman start -f' which seems to get things going again and shows the lists as they were before the snapshot, which is good, but I would like to get the issue fixed so that services start normally.

Hello, mails to list owners with subjects like <Mailaddress>'s bounce score incremented on <MyListName> comes from "user(a)example.com". Where is the right place to change this? We never defined this mail address anywhere. Thank you very much!

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

posting bounced with 501 Message has defects
by Hitashi mancho April 21, 2025

April 21, 2025

Dear All, One of our users posted an email using a Bluemail Desktop client on one of the mailing lists. This email bounced with the reason "501 Message has defects". However, it gets accepted if the same user posts the same email on the same mailing list using Webmail (RoundCube) or Thunderbird. There is nothing in mailman.log and bounce.log, even in debug mode. Following is the SMTP log for the same email posting and the email header. Any guidance in debugging this will be highly appreciated.

Setup Question: Disk-Layout (Migrating from Mailman 2.1)
by christian.schneider＠tu-dortmund.de April 21, 2025

April 21, 2025

Hello, actually I am running the latest available Mailman-2 Version on Ubuntu 20.04! Now it is really time to move on! :-) I want to set up a new server (Ubuntu-24.04) and install Mailman-3 with the Virtualenv setup method: https://docs.mailman3.org/en/latest/install/virtualenv.html As I know from my old Mailman-2.1 the archives could get quite big... ;-) So it seems very important to provide enough (expandable) disk space at the right place. (I plan to use a seperate partition with LVM for the path in question) But I could find no information about the location where hyperkitty stores the archives on an Ubuntu-/Linux-system. I assume the archives are stored underneath "/var/..." this is only a guess. But is this guess right? Another question is: How much space do I have to plan (roughly) for the "/opt"-partition for the mailman install if the archives are stored under "/var/..."? Any guidance ist very much appreciated! Thank you very much Chris

moving from sqlite3 to postgresql
by Michael Richardson April 20, 2025

April 20, 2025

Hi, I installed mailman3 a few years ago on lists.sandelman.ca aka lists.tcpdump.org. My upgrade was in part a response to the HTTP based attacks that used the signup form on mailman2 to attack people via SMTP with DOS. I know the IETF mailman2 install {now gone} had some kind of delay implemented in the web form before you could submit. I didn't understand why. I installed via debian packages, and I'd really prefer to stay with that. (Not what many maintainers would say, I know. Essential that it work if mailman3 is going to take over) There were problems, probably with the hyperkitty integration with subsequent updates seemed to solve. I installed with sqlite3, since it seemed if all work was going to go through the mailman3 daemon, that it would handle all the concurrency issues. This has not been the case. I get weekly complaints about the database being locked. Sometimes this goes way on it's own, but sometimes it does not. A good way to tickle this is to go the web interface, go to a list with 200 held messages, and then having told it to show me 100+ messages per page, to then tell it to discard them all. So slow. Before I realized what was going on, I'd open multiple tabs to try to make this concurrent. So I tried to switch last week from sqlite3 to postgresql. I used pgloader with a configuration file attached below. This seemed easier than a sqlite3 dump/psql, as the SQL requires some massaging that seeemed to require more brainpower than I had at the time. I then edited /etc/mailman3/mailman.cfg to suit. I had set up the postgresql database under the "list" owner, so unix-domain socket permissions, and restarted. I then saw some errors: lists not found! I visited the web interface. NO LISTS. DAMN. I put it back. I haven't figured out what went wrong yet. I will clone the VM and try again. I will report whatever I find here. === load database from '/var/lib/mailman3/mailman.db' into postgresql:///mailman3 with include drop, create tables, create indexes, reset sequences set work_mem to '16MB', maintenance_work_mem to '512 MB'; === ps: I'd pay some $$ money for email support consulting.
