Subscription Request asking for Confirmation instead of Moderation
by Henry Hartley Aug. 29, 2025

Aug. 29, 2025

We have a list where the Subscription Policy (Settings -> Member Policy -> Subscription Policy) is set to "Moderate" and when I send a message to LISTNAME-join(a)example.com<mailto:LISTNAME-join@example.com> (not the real domain, obviously) everything works as expected and the user shows up in the Pending Approval list. We have a Drupal website that allows users to submit a form that, among other things, sends a subscription request to our Mailman3 'join' address. When that happens, however, instead of going to the Pending Approval list, the name is shows on the Pending Confirmation page. We don't send a Welcome message so as far as I can tell, they do not get an email asking them to confirm their email address. Two questions: 1. Are there particular headers that are causing the email to go to the Confirmation page instead of the Approval page? Or are there particular headers we can add that will help with this? 2. Is there any way for us to move an address from the Confirmation Pending page to confirmed on the backend (preferably through the web interface, but on the server itself, if necessary)? Here are the headers sent with the subscriber's email address changed to FirstLast(a)SCHOOL.edu<mailto:FirstLast@SCHOOL.edu> and our BCC mailbox domain changed to COMPANY.com. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8; format=flowed; delsp=yes Content-Transfer-Encoding: 8Bit X-Mailer: Drupal Return-Path: FirstLast(a)SCHOOL.edu<mailto:FirstLast@SCHOOL.edu> Sender: FirstLast(a)SCHOOL.edu<mailto:FirstLast@SCHOOL.edu> From: FirstLast(a)SCHOOL.edu<mailto:FirstLast@SCHOOL.edu> Bcc: mailman-noreply(a)COMPANY.com<mailto:mailman-noreply@COMPANY.com> -- Henry Hartley Westat RB 2151

Today no question, but my toolbox: set "global" user preferences; list or delete held messages
by Wikinaut Aug. 27, 2025

Aug. 27, 2025

After some (sorry for bothering you) questions here, I was able to set up a mailman3 system which I regard as perfect for my use. Perhaps, you had similar problems with your installation, especially when coming from mailman2 and, like me, from majordomo...... I collected a lot of information which was presented in this mailling list archive here and also answers of my questions (thanks Mark and others) News: https://github.com/Wikinaut/mailman3-tools has all of these tools. README says: Scripts for maintenance or setting-up of modern mailman3 instances set preferences for all users list held messages delete held messages older n days My setting is strictly as described in the documentation: mailman3 + postorius/hyperkitty are installed via pip in an (venv) /opt/mailman/ My user scripts and a huge mailing list generator (not published here) are in a directory apart from that: user maillistgen home directory /home/maillistgen user maillistgen has some sudo rights set uo in /etc/sudoers a wrapper script is /home/maillistgen/run_mailman.sh which sets the correct path for Python, mailman3 and the (venv). I hope, you like my tiny part of contribution and attribution back to Mark.

Internal Server Error: /mailman3/postorius/lists/.../held_messages - humanize: where to put?
by Flo Aug. 26, 2025

Aug. 26, 2025

Hi, I have setup in Debian Trixie mailman3-full and came that far, that I have created a mailing list. I can sent emails to the members. However when I send from an email which is non-member the message is held. If I want to accept this message as list admin, I get: `An error occurred while processing your request.` And I get an email: `Internal Server Error: /mailman3/postorius/.../held_messages TemplateSyntaxError at /postorius/lists/.../held_messages 'humanize' is not a registered tag library.

In this file I I configured Django. However it's not in the Python path as written in the error email above. So maybe I have to find a different settings file. Can anyone advise me where I can find the error I have in my configuration? Thanks in advance. Flo

How can i suppress sending moderation mail to all owners?
by Markus Grandpré Aug. 25, 2025

Aug. 25, 2025

Dear list members, How can I configure the list settings the way that emails intended for moderators are delivered only to them, and not to the owners/administrators of the list?

Python backtrace from `mailman -h`

Hi Folks, I'm running the Debian-packaged mailman3 (yes I know ...) and running: sudo -u list mailman -h gives a python backtrace (which I've appended the tail end of). Can someone who has the upstream installed version (using venv) please check that `mailman -h` works there before I waste too much time investigating in the wrong places? ...

Why are moderation mails sent to list moderator (if there are any) _and_ then also to the list owner?
by Wikinaut Aug. 24, 2025

Aug. 24, 2025

Dear all, I am quity puzzled to receive a bunch of mails which are moderators works - I just set up one person as a list moderator - but I do receive the moderation request as well. How can this be stopped? I just tested the behaviour and I can't see any switch in the list settings (at the moment) to avoid sending moderations to the owner for such lists, where moderator(s) are defined. A Bug?

[Bug] Someone not a member of list is treated as member - strange
by Wikinaut Aug. 24, 2025

Aug. 24, 2025

In my list test I have my address1 as member (only this one member). I definitely send a mail from my address2[sic] to ml test. The list settings are: 1. accept mails from members (address2 is not a member) 2. discard mails from non-members (address2 is not a member of ml test) When sending from address2, my mail is accepted. When I, for sake of completeness switch 1. to moderate mails from member[sic], my mail from address2 gets moderated. Please explain. It looks like a bug. I double-checked the field "accept from non-members" to be empty, yes, is empty, where I otherwise add all members by adding the internal ml whitelist in form of the entry @whitelist@mydomain.com .

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.

particular list member seems unmanageable from CLI
by Stephan Aug. 22, 2025

Aug. 22, 2025

We have a list member that got disabled due to bounces, but that should be fixed after we implemented DMARC and SPF. So as I don't know how to access the disabled status from the CLI (we have no GUI), I tried to delete and re-subscribe them. But although they are listed as a member, they cannot be deleted: # sudo -u list mailman members list(a)domain.tld | grep "$x" M... <M....@web...> # sudo -u list mailman delmembers -m "$x" -l list(a)domain.tld Member not subscribed (skipping): M... <M....@web...> How can I fix this from the command line? Either by restoring their "disabled" status, or deleting and re-subscribing them?
