Re: Python 3.13 compatibility

Hi gang, On mailman import21, I hit the error TypeError: 'pathlib._local.PosixPath' object does not support the context manager protocol I found the earlier thread, where Mark wrote > This is https://gitlab.com/mailman/mailman/-/issues/1190 fixed for > Mailman 3.3.11 by https://gitlab.com/mailman/mailman/-/merge_requests/1309 I have (venv) mailman@darni:~$ mailman version GNU Mailman 3.3.9 (Tom Sawyer) I tried (venv) mailman@darni:~$ pip install -U mailman postorius django-mailman3 hyperkitty mailman-web to no avail, the TypeError is not fixed and the version is the same. ok, so I need to spell out a version. Trying pip install -U mailman==3.3.11 postorius django-mailman3 hyperkitty mailman-web 3.3.11 appears not to be available pip install -U mailman==3.3.10 postorius django-mailman3 hyperkitty mailman-web yields the familiar problem with the nntplib.

But the 3.3.10 version may have no verbiage to say that the nntlib is replaced by standard-nntplib Now I seem to have managed to hose my environment.

Delimiter problems
by Christian H. Kuhn March 30, 2026

March 30, 2026

Hi all, i used - as recipient_delimiter for a long time. Now it was brought to my attention that + is the current default, so i changed in the main.cfg of all postfix instances to recipient_delimiter = +- Now of course confirmaiton mails for mailing list qtest to qtest-request@domain fail, because the recipient qtest is unknown. I changed [mailman] listname_chars: [_.0-9a-z] [mta] verp_delimiter: +- but still the generated address is qtest-request@domain. Is it possible to generate emails as qtest_request@domain? If not, would the owner_request_special of postfix help? Kind regards, QNo

Reject with notification not working
by MegaBrutal March 28, 2026

March 28, 2026

I'm creating a newsletter style mailing list where only one address is allowed to send e-mails, members just receive them, but they shouldn't be able to post to the list. Still I want to send a friendly notification if members accidentally try to post to the list, so I set "Reject (with notification)" as "Default action to take when a member posts to the list", but it doesn't work: my test address didn't receive any notification when I tried to send a message to the list. I tried to define the "list:user:notice:rejected" template for the list, but to no avail.

broken route to accounts
by Thomas Krichel March 28, 2026

March 28, 2026

I am using apache to run the web interface, and my Postel port, and I have the proxy routs ProxyPass "/mailman3" "http://127.0.0.1:4386/mailman3" works ProxyPass "/archives" "http://127.0.0.1:4386/archives" works ProxyPass "/accounts" "http://127.0.0.1:4386/accounts" is broken ProxyPass "/admin" "http://127.0.0.1:4386/admin" works ProxyPass "/user-profile" "http://127.0.0.1:4386/user-profile" works What does "is broken" mean here? Well, since I have debug on, GET "http://127.0.0.1:4386/accounts" yields something like (shortened to cut to the salient matter) | <body> | <p> | Using the URLconf defined in <code>mailman_web.urls</code>, | Django tried these URL patterns, in this order: | </p> | <ol> | <li>postorius/</li> | <li>hyperkitty/</li> | <li>mailman3/</li> | <li>archives/</li> | <li>^user-profile/delete$ | [name='mm_user_account_delete']</li> | <li>^user-profile/$ | [name='mm_user_profile']</li> | <li>accounts/</li> | <li>admin/</li> | </ol> | <p> | The current path, <code>accounts</code>, didn’t match any of these. | </p> | </body> Sure I have accounts/ rather than accounts, but neither are working routes endowed with a trailing slash. Digging for mailman_web.urls, I am lead to believe this is related to my settings, and as I inspect them, I am reminded that I appended del ACCOUNT_AUTHENTICATION_METHOD ACCOUNT_LOGIN_METHODS = {'email', 'username'} del ACCOUNT_EMAIL_REQUIRED ACCOUNT_SIGNUP_FIELDS = ['email*', 'username*', 'password1*', 'password2*'] to my settings file. Commenting these lines out, restarting mailmanweb, still the same error. Ideally an error like this should be shown to the user. Instead it leads to a endlessly repeated requests for users to verify their email address, as seen in my live system at say https://lists.repec.info/accounts/confirm-email/ These have no CSS, pointing to an apache missconfiguration For what it's worth, here is my current apache configuration | <VirtualHost *:443> | ServerName lists.repec.info | ServerAlias www.lists.repec.info | ServerAlias list.repec.info | ServerAlias www.list.repec.info | ServerAdmin webmaster@localhost | | RewriteEngine On | RewriteRule "^/?$" "https://lists.repec.info/mailman3/lists/" [R] | | Alias /static "/usr/local/mailman/web/static" | <Directory "/usr/local/mailman/web/static"> | Require all granted | </Directory> | | Alias /favicon.ico "/usr/local/mailman/web/static/postorius/img/favicon.ico" | | <IfModule mod_headers.c> | RequestHeader unset X-Forwarded-Proto | <If "%{HTTPS} =~ /on/"> | RequestHeader set X-Forwarded-Proto "https" | </If> | </IfModule> | | <IfModule mod_proxy.c> | ProxyPreserveHost On | ProxyPassMatch ^/static/ ! | ProxyPass "/mailman3" "http://127.0.0.1:4386/mailman3" | ProxyPass "/archives" "http://127.0.0.1:4386/archives" | ProxyPass "/accounts" "http://127.0.0.1:4386/accounts" | ProxyPass "/admin" "http://127.0.0.1:4386/admin" | ProxyPass "/user-profile" "http://127.0.0.1:4386/user-profile" | </IfModule> | | LogLevel debug | ErrorLog /var/log/apache2/lists.repec.info_error.log | | CustomLog /var/log/apache2/lists.repec.info_access.log combined | ServerSignature On | | Include /etc/letsencrypt/options-ssl-apache.conf | SSLCertificateFile /etc/letsencrypt/opt/live/repec.info/fullchain.pem | SSLCertificateKeyFile /etc/letsencrypt/opt/live/repec.info/privkey.pem | | </VirtualHost> -- Written by Thomas Krichel http://openlib.org/home/krichel on his 22209th day.

Django 5.2 LTS and mailman 3
by dlb-ml＠anl.gov March 27, 2026

March 27, 2026

I noticed that Django 4.2 is nearing EOL status in April (no specific day in April is given): https://www.djangoproject.com/download/ I also noticed that there's a planned update to add support for 5.2 to mailman-web: https://gitlab.com/mailman/mailman-web/-/blob/master/README.rst Is this expected to be released before 4.2 goes EOL? Is there a rough time line? Thanks!

Internal server error instead of web interface
by Christian H. Kuhn March 22, 2026

March 22, 2026

Hi all, https://lists.qno.de/mailman3 shows an internal server error. I followed https://docs.mailman3.org/en/latest/install/virtualenv.html with MariaDB instead of PostgreSQL. Python 3.13.0 pip 25.3 mailman 3.3.11b mailman-web 0.0.10.dev14?g0997bd postorius 1.3.13 Services mailman3, mailmanweb, apache2, uwsgi up and running. uwsgi listens on [::1]:8000, apache2 is configured accordingly. Ports show up in netstat. No errors show in logs. If /mailman3 was a directory, i would have thought of user permission problems. But not with TCP ports. As :8000 is available, i would have thought that there is a problem with uwsgi. Requests arrive there and are processed: [pid: 3185672|app: 0|req: 10/17] ::1 () {28 vars in 409 bytes} [Mon Nov 3 13:24:05 2025] GET /mailman3/ => generated 5038 bytes in 28 msecs (HTTP/1.0 200) 8 headers in 261 bytes (1 switches on core 0) So uwsgi gets the request and delivers data. The problem seems that apache2 does not get the result, and i cannot find any reason. Any help? TIA QNo

list not found
by Thomas Krichel March 18, 2026

March 18, 2026

I am very sorry to you folks for not getting back on the problems I am having to install on Debian testing. There are two reasons. One is that I have been much offline for personal reasons. The other is that I have another machine called tagol where I have been running Mailman3 for about three years, using the Debian packet on Debian testing. As testing move to 3.13 this installation could not run. I replaced mailman-core with a 3.12 venv install, but left the mailman3-web package of Debian. This half-arsed job held up for a long time but two weeks ago collapsed. No email went through. I have been trying to switch to a full venv version, still staying with 3.12. Tagol hosts a single list mailman@tagol:~$ mailman lists 1 matching mailing lists found: bibnez(a)folks.email I have some bad queue files.

Subscription confirmation email
by Eric Broens March 15, 2026

March 15, 2026

While doing some tests I subscribed to a mailinglist by sending an email to <list>-join@<domain> Mailman correctly emailed the confirmation request, and the mail was accepted by my ISP. For some reason the confirmation mail did not arrive in my mailbox nor in my spam folder, it seems to have been silently dropped. A day later, I again sent a subscription request to <list>-join@<domain>, and I received a mail from <list>-bounces@<domain> with subject "The results of your email commands" saying that I have a pending subscription for that mailinglist. However, no confirmation link is included, nor instructions to visit the website to confirm the subscription. Am I missing something in the configuration? I would expect that a confirmation request is mailed again to the subscriber. Most subscribers don't use the web interface to manage their subscriptions. The versions running with Maxking's docker-mailman and postfix are: Mailman Core versie GNU Mailman 3.3.10 (Tom Sawyer) Mailman Core API versie 3.1 Mailman Core Python versie 3.12.7 (main, Oct 7 2024, 11:30:19) [GCC 13.2.1 20240309] Best regards, Eric

[GSoC 2026] [Feature Proposal] Per-List Backup and Restore Support
by sonika gutha March 14, 2026

March 14, 2026

*Introduction: * My name is *Sonika Chowdary Gutha*, and I am a *second-year Computer Science undergraduate at BITS Pilani, India*. I recently completed a *6-month internship in Backend Development using Python and Django*, where I gained experience in building backend systems and working with REST APIs.I am also familiar with the *MERN stack and the Flutter framework*, and I have experience developing both web and mobile applications. In addition I have been introduced to the fundamentals of several programming languages, including *Python, C++, and JavaScript*. I am exploring the possibility of implementing a *per-list backup and restore feature* for Mailman. The goal of this feature is to allow list administrators or owners to *export the configuration and membership data of a specific mailing list into a portable backup file and restore it later when needed*. This could be useful in situations such as: - Migrating lists between servers - Recovering from configuration mistakes - Replicating list setups across environments *Implementation:* The following diagram provides a visual representation of the proposed backup and restore workflow <https://excalidraw.com/#json=PhUB9tdMrupMfpx7O6_i6,OLBUtBJjL5_sCR-UokrNHw> .: I plan to implement this feature in two parts. The main backup and restore logic should live in *Mailman Core*, since that is where the actual list configuration and membership data are stored. My idea is to define a *versioned JSON format* that captures the important per-list data such as list settings, members, owners, moderators, and relevant subscription preferences. On the export side, Core would gather this data and write it into a portable backup file. On the restore side, it would read the file, validate its contents, recreate the list if necessary, and restore the saved settings and memberships. On the *Postorius* side, I would implement the user-facing workflow for this feature. This would include an option for list owners or administrators to download a backup file for a specific list, as well as a page where they can upload and restore that file when needed. For the initial version, I plan to keep the feature focused and reliable by covering configuration and membership data first, while leaving more complex areas such as archives or other external components out of scope unless they are explicitly expected. *Questions:* 1. For the first version, what exactly should be included in the per-list backup: only settings and memberships, or also items like templates, ban lists, and member preferences? 2. Should the main export and restore implementation live in Mailman Core, with Postorius mainly responsible for the UI and workflow? 3. Is a *versioned JSON format* the preferred choice for the backup file? 4. Should restore only support creating or recreating a list from backup, or should it also support restoring into an already existing list?Thank you for your time and feedback.

venv and upgrade from python 3.11 to 3.13 because of OS-upgrade
by Andreas Vetter March 13, 2026

March 13, 2026

Hi, I have a venv installation (mailman postorius django-mailman3 hyperkitty mailman-web) with python 3.11 from the Linux distribution. Since distribution EOL nears, I checked python version in next distribution and it is python 3.13. So my guess is, after distro upgrade, this will stop working. How should I upgrade? -- Mit freundlichen Gruessen, Andreas Vetter

Where to start looking?
by Paul Tomblin March 12, 2026

March 12, 2026

So I imported all our mailman2 lists into mailman3, and it appears it didn't preserve passwords. So my wife (who administers 3 lists of her own) tried to use the reset password link (multiple times) but she never gets the email. I don't see any outgoing email to her in mail.log, or any of the mailman logs. I do the exact same thing as her and I get the email. Any suggestions on what I should be looking for? -- Paul Tomblin

Accept these non-members
by Lars Bjørndal March 10, 2026

March 10, 2026

Hi, list! I have an announce only Mailman3 list. When I log into the web interface as an admin user, and go to the specified list, and choose Settings, I find the Message Acceptance tab. There, I find the edit field Accept these non-members. But this field is empty, although I know that some people have permissions and are able to post to this list. How can I find the list of these non-members and add more people or delete someone? I'm running Mailman version 3.3.10, and mailman-web version 4.2.21. Any hints? Thanks, Lars

Additional info/tags on Members
by mkoerber＠akamai.com March 9, 2026

March 9, 2026

I am managing a few mailing lists which are hosted on a mailman3 instance. None of these are allowing self-subscription, but I have a need to be able to search the membership by association, ie whether they belong to any of a number of named groups Currently there does not seem to be any means for attaching a comment field, tag or such to group members, which would allow keeping such metadata and using it for searching members. (and no, the email addresses of members of one or more groups may not be similar, hence searching by @domain or such will not work) Also, the group-association info should *not* be exposed externally (ie to the member in question or any others), which makes adding the tag/group info as part of the full name impossible. Is there any way to do this in mailman3? If not can this be counted as a feature request: - in mailman3 itself: + add a facility that allows storing additional info to each member , either as a (largish) comment field or an array of tags ++ if tags, it should support managing thousands of them (but each member is likely to only need a few associated) + if tags are used, each list should have its own set of tags (though a means to designate a list to participate in a global tag collection might be useful). - in postorious: + allow modifying the comment field, or adding/removing/modifying one or more tags to each list-member + allow searching a group's membership by tags (or substring in the comment field), ++ following which mass-operations (deletion, setting moderation flags etc) should be possible based on individual selection of the found fields mailman3 really only would need to support storing the additional data for each member, as (at least in my use case) that data is not actually required for mail forwarding. However, it seems to be desirable to store the info in the mailman3 database rather than an external system (to reduce chances that these might get out of sync).

Opinions wanted.
by Mark Sapiro March 9, 2026

March 9, 2026

There is currently a merge request at <https://gitlab.com/mailman/django-mailman3/-/merge_requests/345> to hide the "Results per page:" dropdown from some Postorius and HyperKitty pages when the full list of items (lists) is on the page. I.e. when the number of items is <=10 and the "Results per page:" is the default 10, don't display the dropdown. However there is some controversy over whether this should also apply say when the number of items is > 10 but still is on one page. So the question is if we are going to hide the dropdown when "Results per page:" is the default 10 and there are <= 10 items so all are on the page, should we also hide it when say "Results per page:" is 25 and there are 22 items all on the page. Your opinion on this is requested via a reply in this thread. See the merge request (link above) for arguments pro and con. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

Debian bug report
by Paul Tomblin March 3, 2026

March 3, 2026

So I went to submit a bug report to Debian about the fact that the mailman3-web page drags in nginx for no reason. Turns out that the bug had been reported in 2021 and nobody who worked on it who understood mailman understood apache and nobody who worked on it who understood apache understood mailman[1]. So I submitted an update. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1002795 [1] Literally, one of the developers said Thanks, I admit initially I had no plan on supporting apache2 as I don't use it. Jonas did that part and therefore I did not follow at all. -- Paul Tomblin

What depends on libapache2-mod-proxy-uwsgi? Mailman core doesn't depend on that at all. It always uses gunicorn as the WSGI server for the REST API, and the Apache config uses ProxyPass on port localhost:8001. And sez who? Are you asking apt or dpkg? I thought you have installed via pip into a virtual environment -- what apt and dpkg think about Mailman dependencies is irrelevant. > > > Is it possible to upgrade to 3.10 with pip? If you installed using Debian, you can't upgrade with pip -- that's a Debian restriction. You have to remove the Debian package(s), and create a virtual environment, typically under /opt/mailman, to install the Mailman suite into. Then, if you have already working lists, you have to either (1) "very carefully" move all the /var/lib/mailman data from your working Debian install into /opt/mailman in appropriate places, or (2) configure the new Mailman to look for data where Debian put it (if you're lucky you can re-use Debian's /etc/mailman3/mailman.cfg for that, although they may have patched the source). The /var data is the queues (mostly bad and shunt, but you may have orphaned qfiles in out, and very very rarely in other queues), the logs, and any in-progress digests being accumulated. The list configurations, user profiles, and most volatile data (eg, pending confirmations) will be in your database. You can use the Debian packaged database, just point the new Mailman at that. > > Yes: see https://pypi.org/project/mailman/. > > Use python3 -m pip install --upgrade mailman. > > Nope, that doesn't work. > python3 -m pip install --upgrade mailman 2>&1 | tee bar > Requirement already satisfied: mailman in ./venv/lib/python3.13/site-packages (3.3.9) Where is '.'? If it's under /var/lib or /var/share, you've got Debian's mailman and you can't upgrade with pip. You want it to be under /usr/local (ugh) or /opt/mailman (happy face). > Collecting mailman > Using cached mailman-3.3.10-py3-none-any.whl.metadata (2.4 kB) [...] > Requirement already satisfied: zope.schema>=4.9 in ./venv/lib/python3.13/site-packages (from zope.configuration->mailman) (8.1) Are you saying pip returns to the shell prompt without doing anything after that? > If I'm reading that right, I have to guess which requirements I > need to force an update on before it will upgrade mailman. No, that's saying all requirements are satisfied for mailman-3.3.10 as far as I can tell. Are you working as the right user? (If you've previously used Debian packages and have working lists, you probably want to continue using Debian's preferred 'list' user, otherwise you may create a 'mailman' user.) If it's not lacking write permissions to the virtual environment, I have no idea why this isn't working. The only thing I can suggest is the same as Mark, force version 3.3.10 with python3 -m pip install --upgrade mailman==3.3.10 and see what happens.

Hi List, I may be in the wrong place so bear with me. I'm working at a volunteer organization with around a dozen mailing lists that were previously on mm2 that have been upgraded to mm3 with the upgrade to debian trixie. Mailman is running and the lists all work ok but i found 1800 mails in the shunt queue. Hyperkitty also shows all the old archives pre 2020 the same as in the django console. When i tried to unshunt the mails they moved to the bad queue. How do i find whats wrong here?

message duplication and an NNTP related error
by Laurens Kils-Huetten Feb. 28, 2026

Feb. 28, 2026

Good day, I have recently installed mailman3 on a Debian trixie system. While I managed to set up most of it (the mailing lists, postorius and also a working gateway to our inn2 news server) I'm seeing a weird duplication of messages, that seems to be related to the error messages posted below. When I switch off gating to nntp the duplication stops. Also only mail messages are duplicated, not the postings on the news server. Any pointers as to what to look into, or how to remedy this problem are greatly appreciated :) Thanks, Laurens here come the error logs: Feb 23 20:39:08 2026 (2776528) ACCEPT: <e4938b85cbd75c0b04867514fc0b8ad9(a)betola.de> Feb 23 20:39:10 2026 (2776528) ACCEPT: <e4938b85cbd75c0b04867514fc0b8ad9(a)betola.de> Feb 23 20:39:12 2026 (2776530) <e4938b85cbd75c0b04867514fc0b8ad9(a)betola.de> NNTP error for test(a)grenzland.club Traceback (most recent call last): File "/usr/lib/python3/dist-packages/mailman/runners/nntp.py", line 94, in _dispose conn.post(fp) ~~~~~~~~~^^^^ File "/usr/lib/python3/dist-packages/nntplib/__init__.py", line 916, in post return self._post('POST', data) ~~~~~~~~~~^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/nntplib/__init__.py", line 909, in _post return self._getresp() ~~~~~~~~~~~~~^^ File "/usr/lib/python3/dist-packages/nntplib/__init__.py", line 492, in _getresp raise NNTPTemporaryError(resp) nntplib.NNTPTemporaryError: 441 Can't set system Injection-Info header field

Weird emails
by Paul Tomblin Feb. 26, 2026

Feb. 26, 2026

I've got my server set up correctly (I hope) and on an https connection, and I *think* I've got it set up so mailman-web will only respond on localhost:8000, but I occasionally get a flood of emails like this: > Internal Server Error: /admin/login/ > > DoesNotExist at /admin/login/ > Site matching query does not exist. Followed by a bunch of Django stuff, followed by > HTTP__X__CLIENT_IP = '127.0.0.1' > HTTP__X__FORWARDED_FOR = '127.0.0.1, 185.177.72.38' > HTTP__X__FORWARDED_HOST = '96.126.110.20' > HTTP__X__FORWARDED_SERVER = 'list.xcski.com' > HTTP__X__FORWARED = '127.0.0.1' > HTTP__X__HOST = '127.0.0.1' > HTTP__X__ORIGINATING_IP = '127.0.0.1' > HTTP__X__REAL_IP = '127.0.0.1' > PATH_INFO = '/admin/login/' > QUERY_STRING = 'next=/admin/' > REMOTE_ADDR = '127.0.0.1' The HTTP_X_FORWARDED_FOR was a clue where it was coming from, and grepping through my apache access logs shows a script kiddie at 185.177.72.38 hammering a miliion urls, 99% of them 404s.

Documentation errors

On the documentation about migration at https://docs.mailman3.org/en/latest/migration.html, there are two commands that start `python manage.py hyper kitty_import|update_index_on_list`, but there is no manage.py installed if you install Mailman and Mailman web following the instructions. Instead, I was able to run them using `mailman-web hyperkitty_import|update_index_one_list` instead. What is the correct method for reporting these errors?

I created a new domain, and a new list, and tried to import the settings from the old pickle file using mailman import21 pt-test(a)browncroftna.org /var/tmp/var.lib.mailman/lists/pt-test/config.pck (in the virtual environment shell) but I get the following error ``` File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/utilities/importer.py", line 512, in import_config_pck default_value = getUtility(ITemplateLoader).get(newvar, mlist) File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/model/template.py", line 211, in get path, fp = find(default_uri, mlist, code) ~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/utilities/i18n.py", line 157, in find for search_path in raw_search_order: ^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.13/site-packages/mailman/utilities/i18n.py", line 117, in search templates_dir = str(resources.enter_context( ~~~~~~~~~~~~~~~~~~~~~~~^ files('mailman').joinpath('templates'))) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/contextlib.py", line 528, in enter_context raise TypeError(f"'{cls.__module__}.{cls.__qualname__}' object does " f"not support the context manager protocol") from None TypeError: 'pathlib._local.PosixPath' object does not support the context manager protocol ``` All I can find on Google is a suggestion that I have a non-empty `bounce_info`, but `dumpdb` shows it as empty.

Customizing Postorios web templates
by Stefan Bethke Feb. 23, 2026

Feb. 23, 2026

Hi, I have two list servers that I would like customize the web pages for, specifically I need to add some legal information to the footer, and I might want to apply some light branding to the site. I can't find any hints on how to do that, maybe I'm looking in the wrong place? If Postorious does not currently allow that outright, it seems I would need to fork mailman/postorious, replace templates like https://gitlab.com/mailman/postorius/-/blob/master/src/postorius/templates/…, and build the package myself. Is this assessment correct? If so, would there be interest in adding a feature to define some blocks that can be overridden more easily, especially during deployment and without having to build custom Python packages?

Digestion debugging
by John Price Feb. 21, 2026

Feb. 21, 2026

I'm having trouble getting digests to work. When I try to manually send one, it does nothing, and then the digest gets deleted (I guess?). I would love it if the documentation explained a bit more how the process works. How are the files gathered? What file can I backup and later restore if I'm debugging it? Also, how are the digest issue and volume numbers work? Is there any way to control that? Since I've been running digests for decades, can I set the volume and issue to what I want so that the numbering continues from where the other installation left off? Thanks, John -- Why do they lock gas station bathrooms? Are they afraid someone will clean them?

Hello, On my new MM3 that I just installed, I testing unsubscribe user from mailing list. User received email for the unsubscribe in subject line as 'You have been unsubscribed from the Test1 mailing list' with email address 'test1-bounces@domain'. It should receive from test1-unsubscribe@domain instead. Where should I look into this? or configure it. Thanks, Marin

Reply to Confirmation Email During Subscribe Process Receiving ListName-Bounce@Domain
by msok＠lalawlibrary.org Feb. 16, 2026

Feb. 16, 2026

I'm new to MM3. I just finished install it. I setup a test list with default settings as test1@domain. I added a user to the list via Mass Subscription with Pre confirm check and Pre approved check. Inside the user inbox in GMail account received email from address test1-confirm@domain ( I added this erp_confirm_format: $address to [mta] in /etc/mailman3/mailman.cfg) with Your confirmation is needed to join the test1@domain mailing list. I replied to the email and I received another email as test1-bounce@domain. I went to my mailing test1@domain. I found a user that I tried to add list in 'Subscription request' under 'Pending Confirmation'. Could you help me to troubleshooting on this? Why I received a list-bounce@domain instead of successfully added or something. Thanks, Marin

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

Mailman and Postfix Conflicting Information
by dap1＠bellsouth.net Feb. 9, 2026

Feb. 9, 2026

I've been going in circles between mailman and postfix trying to get things working. My current condition is that either mailman is putting incoming mail in the bit bucket or postfix is not sending incoming mail to mailman. According to the postfix forum my mailman configuration is messed up but it was auto generated by the installer. Supposedly these entries should not be in /opt/mailman/mm/var/data/postfix_lmtp or rather transport_maps and/or local_recipient_maps. # Aliases which are visible only in the @gmail.com domain. lllllllllll(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-bounces(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-confirm(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-join(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-leave(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-owner(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-request(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-subscribe(a)gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-unsubscribe(a)gmail.com lmtp:[127.0.0.1]:8024 And relay_domains shouldn't have this entry either in /opt/mailman/mm/var/data/postfix_domains in relay_domains: gmail.com gmail.com Clearly my postfix configuration is messed up but since this was all auto generated I don't know what to do.

Maybe until they confirm the user > record is not created yet? If the address was just added from a nonmember post, it won't have a user record. As I said before, there is no pending confirmation for the nonmember. The address has been added as a nonmember and that's it. They won't be added as a member unless they request subscription at which point they will have to confirm if the list's subscription policy requires it. > Anyway, I'd love a subscribe timestamp so I could calculate how long it > has been, but I can rig something up with a daily cron job and a simple > DB of emails and the date it noticed them on the non-members list and > delete them after a few days. Thanks for the info! For the nonmember, nonmember.address.registered_on is probably the timestamp you are looking for. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

The User object is created. User records don't get confirmed, the addresses that are attached to them get confirmed. > Anyway, I'd love a subscribe timestamp so I could calculate how > long it has been Some of the object records have creation timestamps in the SQL database, but they are not exposed in the web UI. They're not very interesting to human beings and take up a lot of UI space, even if you only display the date. Also, I'm not sure whether the core database records timestamps, although I'm pretty sure Django does for both creation and confirmation. -- GNU Mailman consultant (installation, migration, customization) Sirius Open Source https://www.siriusopensource.com/ Software systems consulting in Europe, North America, and Japan
