Opinions wanted.

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

How to upgrade to 3.10

March 8, 2026

I installed 3.9 with pip last week, but i want to upgrade to 3.10. But pip install -U mailman postorius django-mailman3 hyperkitty mailman-web doesn't upgrade it. Requirement already satisfied: mailman in ./venv/lib/python3.13/site-packages (3.3.9) Collecting mailman Using cached mailman-3.3.10-py3-none-any.whl.metadata (2.4 kB) Requirement already satisfied: postorius in ./venv/lib/python3.13/site-packages (1.3.13) ... a bunch of these ...

Accept these non-members
by Lars Bjørndal March 6, 2026

March 6, 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

I need to set some nonmembers to a list as these members send message to the list, but don't need to receive any message from the list. I've used list_name.settings['accept_these_nonmembers'].append to add members to the list, but it gets discarded once I run list_name.settings.save().

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.

Debian upgrade Hyperkitty not archiving
by Phil Steel-Wilson March 1, 2026

March 1, 2026

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. Is there any way the code could just return a 403 or 418 instead of getting a python error? -- Paul Tomblin

Documentation errors
by Paul Tomblin Feb. 23, 2026

Feb. 23, 2026

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?

Can't import from Mailman 2.1
by Paul Tomblin Feb. 23, 2026

Feb. 23, 2026

I set up a new Mailman site using 3.3.10, and copied over my files from my old mailman site (using 2.1.34). 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.

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

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.

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

Expire non-members
by John Price Feb. 8, 2026

Feb. 8, 2026

Is there a way to expire and delete (in mailman3 or via cron) non-members? I've been running mailman3 for a couple of weeks now on a few mailing lists, and on my big list specifically I'm seeing lots of spam to the gcfl-join(a)gcfl.net email alias, which creates these non-members, but they never confirm their subscription, so they remain in non-member limbo. Thank you, John -- Is it my imagination, or do buffalo wings taste like chicken?

Please explain why you think that. Note: The sender address that is changed is the envelope address. You won't see it in the message headers in most cases.

Permissions Error on /var/mail/mailman
by dap1＠bellsouth.net Feb. 5, 2026

Feb. 5, 2026

I am going in circles between postfix issues and mailman. However, before I continue with postfix debugging I want to resolve this first as it may be related for all I know. I'm getting this error in the postfix mail log: 2026-02-01T11:00:10.106626-05:00 dap002 postfix/local[113730]: 01623500076: to=<mailman(a)myhost.localdomain>, orig_to=<mailman>, relay=local, delay=0.16, de lays=0.11/0.01/0/0.04, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/mailman for user mailman. cannot open file: Permission denied) I'm not sure why mailman is trying to write to that file but it is owned by root:mail. It is obvious why permission is denied to mailman. Is that directory really part of mailman3 and if so what should ownership and permissions be? If not then why is mailman trying to write to it? That path does not appear in any of the files in /etc/mailman3.

Is there an option to "disable" a list temporarily? (feature request?!)
by Christian Schneider Feb. 4, 2026

Feb. 4, 2026

Hello dear Mailman Team, I scanned through the web interface of my mailman instance... and I did not find an option to disable a list temporarily ("sending" and "access to web interface")... This might come in handy when a list is abused for sending spams or when a list owner wants his/her list to be removed... Instead of removing the list instantly I would disable it for three months first... (You never know with users... ;-) ) Preferably I would backup the list (settings and members) and the archives, but as seen in the discussion there is actually no backup mechanism for lists... Is there an option to disable a list (except from resetting passwords and remove/disable mail aliases)? If not I'd like to hand this in as a feature request... xD Thank you very much and kind regards Christian

Request for ideas and mentors for Summer of Code 2026
by Stephen J. Turnbull Feb. 3, 2026

Feb. 3, 2026

Hi all, The GNU Mailman Project is applying for Google Summer of Code 2026[1]. Our Ideas Page[2] has been updated. We're still open for mentors, of course, and ideas. There's no deadline, but to be most useful it would be helpful to have these suggestions by February 19 when Google announces selected organizations. Summer of Code projects must involve substantial amounts of new code. The effort involved should be 150 to 200 hours (although programmers' skills may be anywhere from "novice" to "10x", so the amount of code can vary more than that!) Projects which are primarily documentation, user interface skinning, or tests are usually ineligible. Please send those to me by email or on this list if you think the idea would be of interest to other Mailman users, or might trigger suggestions for improvement from them. We are also interested in "tiny" tasks which are suitable for demonstrating interest and making the applicant familiar with our review process. If you have some minor annoyance (whether bug or missing feature) that you think might take an experienced Mailman dev an hour, this is a good chance to get some eyes on it. For these it would be most helpful if you file an issue on the relevant project (usually core[3], Postorius[4], or HyperKitty[5]), and mark it "easy" and "GSoC", and "beginner-friendly" if appropriate. (The difference between "easy" and "beginner-friendly" is "easy" means low effort, while "beginner-friendly" means it does not require prior knowledge of Mailman internals or non-stdlib Python modules such as SQLAlchemy, Zope, or Django.) Documentation and testing tasks are welcome here. Looking forward to your ideas!

Phantom Email Address in Nonmember List
by Steve Brown Jan. 31, 2026

Jan. 31, 2026

Have an issue that is more of a puzzle than a problem. No real harm done. So don't spend much time on it if you don't recognize the issue. I am administrator for a small list, radg(a)lists.radg.us, hosted by Mailmanlists.net. They are trying hard to figure it out but so far unsuccessful. Looking at the headers of emails sent from steve(a)stevebrown.us to the list and boomeranged back to me, I see a line “X-MailFrom: bounce+66273f.99dcd9c-radg=lists.radg.us(a)stevebrown.xn--us-02t. I gather that it is designating the return path where a message would be sent if there was a delivery problem. From its position in the header, I suspect it is added as they pass through Mailgun, maybe related to DKIM. I am hoping you might know why that bounce address is recognized by Mailman 3 as a real address for my emails, but not for others, even from my wife’s computer traversing the same path from our home to the Mailman 3 server. The Mailman installation does get and process the post, but also puts the “bounce+,,,” address in its list of nonmembers. Mailmanlists.net hasn’t figured out the behavior. I can provide full header information if that would help. My understanding of how headers work is very limited. Steve Brown

Domain defaults for new lists
by Peter Chubb Jan. 30, 2026

Jan. 30, 2026

Hi Folks, Is there a simple way to set up the defaults for any newly created lists? We've had a few cases recently where in the time between creating a mass-populated list and making it private it's been inundated with spam. I'd like to change the defaults so newly-created lists are private and have private archives, new members are moderated, etc., to give time for the list to be set up completely before announcing it to the world.

Disabling Mass operations
by iMark Jan. 24, 2026

Jan. 24, 2026

Hi All, Can anyone give me a pointer on disabling "Mass operations" (subscribe/removal) in Postorius. Just removing the menu link from the list-owners administration pages would be a good start. On "list-by-list" would be brilliant, but even server-wide would do the job. Cheers, Mark

Change Member's Address
by dap1＠bellsouth.net Jan. 15, 2026

Jan. 15, 2026

How do I manually change a member's address? I can't find any way to do that from the mailman-web pages. Do I need to do it within MySQL somewhere? TIA.

Any known cases of "non-members" who aren't explicitly allowed to send to the list with a default rule of "discard" on a list getting through?
by Thomas Ward Jan. 10, 2026

Jan. 10, 2026

We just noticed an oddness in a client's system. Someone sent to a members-only list and it 'got past' moderation controls. The list is set to not allow non-members to send to the list, but somehow it got through the default rule of "discard (no notification)" for a non-member and got to the list. The only oddness I can tell is that there was an emoji (unicode) in the subject line but as I understand how Mailman works, this should NOT have impacted anything, as the sender filter bits happen earlier in message processing. Has *anyone* seen any cases like this before? If this is repeatable or a known issue, it deserves a CVE security bug because this is a **severe** problem.

Unadvertised lists accessible even if not signed in
by Peter Chubb Jan. 5, 2026

Jan. 5, 2026

Hi folks, I'm running Mailman3 3.3.10, with postorius and hyperkitty. I want unadvertised lists to be visible only to the people who are subscribed to them and to site administrators. Right now, anyone who has the name of a list can construct a URL to the signup page, even for unadvertised lists. So, I can go to: https://site.name/postorius/lists/test.site.name/ and get to the test list, even if it is unadvertised. I see people scanning URLs like this in the NGINX logs, looking for lists. How can I prevent anyone not logged in, and not a member of an unadvertised list, from seeing it? Peter C

Getting original message headers
by Peter Chubb Jan. 5, 2026

Jan. 5, 2026

We've been seeing some particularly pernicious spammers recently. They're using gmail accounts; I'd like to report them to Google. To do that I need to find the original message headers. By the time the message gets to the archive, or to the mailing list recipients, all the Received: headers seem to have been deleted, leaving only the ones from my list server outwards. Is there a way to access the original incoming emai, before DMARC mitigation etc., has changed the headers? Peter C

Confirmation Email Not Sent
by dap1＠bellsouth.net Dec. 31, 2025

Dec. 31, 2025

While waiting for the Django problem to be resolved, I am able to make it accept a specific host login to get around the CSRF error. So I am now trying to add a member to my list using the ...join address. I get back a message saying the request is pending. I can also see it on the pending user confirmation page. However, there is nothing showing up on the pending approval page nor is there anything in the mail.log showing an outgoing confirmation email or email to the list admin about a pending approval. There is nothing in the mailq either, Looking through the logs I see nothing helpful. Where is the confirmation email?

Cannot Run Web Frontend
by dap1＠bellsouth.net Dec. 27, 2025

Dec. 27, 2025

I'm having trouble getting my web frontend working. When I try to access http://localhost/mailman3 I get a 503 error and the following in the apache2 error.log: [Tue Dec 23 13:08:41.584412 2025] [proxy:error] [pid 132768] (111)Connection refused: AH00957: http: attempt to connect to 127.0.0.1:8000 (127.0.0.1:8000) failed [Tue Dec 23 13:08:41.584578 2025] [proxy_http:error] [pid 132768] [client 2600:1700:5cac:4600:fc36:9a27:6e66:44b:49658] AH01114: HTTP: failed to make connection to backend: 127.0.0.1 This is the relevant part of apache2's 000-default.conf: <IfModule mod_proxy.c> ProxyPreserveHost On ProxyPass "/mailman3" "http://127.0.0.1:8000/mailman3" ProxyPass "/archives" "http://127.0.0.1:8000/archives" ProxyPass "/accounts" "http://127.0.0.1:8000/accounts" ProxyPass "/admin" "http://127.0.0.1:8000/admin" ProxyPass "/user-profile" "http://127.0.0.1:8000/user-profile" </IfModule> What is a bit confusing but probably unrelated is this is in the virtual section for port 80 rather than port 443. I don't see any errors anywhere else.
