How To Install Mailman 3 on Debian 10 (Complete Guide)
by Brian Carpenter Feb. 25, 2025

Feb. 25, 2025

I have finished my how-to install Mailman 3 on Debian 10 completed to the point where you can use it to get a fully functional Mailman 3 environment up and running. This is a comprehensive guide that walks you through installing EVERYTHING (currently!) that Mailman 3 needs to run. It also makes updating Mailman 3/Postorius/Hyperkitty very easy. I have not added the update directions yet but will very soon. I also plan on adding a section on setting up DKIM and Xapian with Mailman 3. I hope this helps those who wish to get a Mailman 3 server up and running quickly and brings a sense of sanity to the confusion regarding the various documentation out there concerning the installation of Mailman 3/Postorius/Hyperkitty. I intend to add a How-to for Ubuntu 20 at some point. Without further ado: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 I am sure the above guide can use improvements. Feel free to contact me off-list to point out mistakes/improvements, etc. -- Brian Carpenter Harmonylists.com Emwd.com

Speed up importing mailman2 lists
by t.maintz＠fz-juelich.de Feb. 24, 2025

Feb. 24, 2025

We are currently planning to migrate from mailman2 to mailman3 as a container, have around 1500 lists and would like to complete the migration ideally in a few hours. We would like to switch off mailman2 to have a defined state of the lists and import them to mailman3. The import of all lists via script takes about 3 days. Parallelizing the imports does not work due to lockings in the database. However, we cannot accept a downtime of 3 days. Does anyone have tips on how we can speed up the procedure or are there best practices for larger environments? Thanks and best regards, Thomas

clean up spambot generated accounts
by Johannes Rohr Feb. 23, 2025

Feb. 23, 2025

Dear all, I'm trying to find a way to clean up hundreds of spambot generated accounts on my system. I was pointed to this script that should be capable of doing the task: https://www.msapiro.net/scripts/clean_users.py However, it seems outdated. First, the path to the interpreter is not what I find on my mailman3 installation. It says: #! /opt/mailman/mm/venv/bin/python However, the python command is located in /opt/mailman/venv/bin/python instead, no "mm" After fixing this, the script still throws an error: (venv) mailman@ida:~$ clean_users.py Traceback (most recent call last): File "/usr/local/bin/clean_users.py", line 55, in <module> django.setup() File "/opt/mailman/venv/lib/python3.10/site-packages/django/__init__.py", line 19, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "/opt/mailman/venv/lib/python3.10/site-packages/django/conf/__init__.py", line 102, in __getattr__ self._setup(name) File "/opt/mailman/venv/lib/python3.10/site-packages/django/conf/__init__.py", line 89, in _setup self._wrapped = Settings(settings_module) File "/opt/mailman/venv/lib/python3.10/site-packages/django/conf/__init__.py", line 217, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1004, in _find_and_load_unlocked ModuleNotFoundError: No module named 'settings' Can somebody explain to me, why this module is not found and what I can do to fix it, if anything?

Hyperkitty performance problem
by Tobias Diekershoff Feb. 20, 2025

Feb. 20, 2025

Hey all, last week we caught some AI bots causing high LOAD on our mailman3 servers archive, that we blocked with nginx rules. I'm not sure if it is related to this incident, but we noticed this when analyzing the log files at the time. In the mailman.log hyperkitty is listed 10k times and more to archive a single mail over the time of 2h, seemingly all with the same process ID > (1186) HyperKitty archived message [...] The mailman3-web.log has matching log entries that the mail was archived > hyperkitty.views.mailman Archived message every 0.5 seconds. In the web interface to the archive, the mail is only listed once though. My suspicion is, that these archiving processes are now overloading the system, preventing a timely catching up work of the queued messages. I could not find anything in the Mailman3 nor Hyperkitty documentation to better distribute the system resources to the Mailman runner or prevent Hyperkitty to restart archiving a mail over and over again. Any hint about where to look for the reason of this is highly appreciated.

Mailman Core: REST API: Member Subscription Invitation
by Peter Knowles Feb. 20, 2025

Feb. 20, 2025

Product: Mailman Core Version: 3.3.10 When I post an "invite" to the REST API: http://localhost:8001/3.1/members Params: list_id = list.domain.tld subscriber = some(a)email.address display_name = Some Name invitation = true Should Mailman Core be attempting to send an "invitation" email to the "subscriber" address, or is this the job of the "client" calling the API? I understand the API does return "token", and "token_owner" on success, which I assume the "token" would be used for a subsequent "verification" process. I'm developing my own "frontend" for "subscribers", "moderators", "list admins", and "system admins" respectively. Sort of working through understanding what Core does and does not do itself.

REST API: potential bug
by Peter Knowles Feb. 16, 2025

Feb. 16, 2025

I'm starting to develop against the REST API and found what might be a bug in the validation process. Sending a POST request with an "empty" payload returns 201 (created): http://localhost:8001/3.1/domains Since "mail_host" should be required at minimum to create a domain, this seems like there may be a bug with the REST API. The workaround for the moment is to add validation at the application layer, but the API should really be returning a 4xx code and error respectively.

I'd like to install Mailman v3.3.11. Are there instructions for installing from pip? If not, is there an alternate way to install this latest version? When executing: pip install mailman==3.3.11 I get: ERROR: No matching distribution found for mailman==3.3.11 Thank you,

Re: Moderation action "None" is misleading
by Stephen J. Turnbull Feb. 13, 2025

Feb. 13, 2025

Adding mailman-users(a)mailman3.org. Technical suggestions should go to distro channels or to Mailman's issue tracker: https://gitlab.com/mailman/mailman/-/issues/1176. Further discussion of technical details is best done there. Thomas Krichel writes: > Stephen J. Turnbull writes > > Debian has traditionally been quite slow to update Mailman, > > And now it has the addition issue that Debian testing python > standard it 3.13, so the nntplib is no longer supported. > Thus the current Mailman debian testing appears broken. That's Debian's problem, as we currently don't support Python 3.13, although of course we intend to. This is the only issue that came up in a quick search of Mailman's issue tracker for Python 3.13 (but I did not check the other subprojects such as Postorius). I conclude that not a lot of work has been done on supporting Python 3.13 (rather than the optimistic "there's nothing to be done"). From Mailman's point of view, users have two excellent options for the forseeable future: (1) don't gateway list <-> newsgroups (2) install Mailman into a Python 3.9--3.12 virtual environment. I'm sympathetic to the needs of the Debian developers, and at this point for 99% of software it's perfectly reasonable to aim to use 3.13 in the next Debian release. Unfortunately for Mailman users on Debian hosts that's not high on our list of priorities since we recommend a virtual environment installation in any case. At present there seem to be three ways forward for Debian packaging: 1. Remove NNTP support. (In honor of larsi, I'd rather not.) 2. Add nntplib.py from the Python 3.12 nntplib, as a stopgap until option 3 can be implemented. I can't speak for other developers but we might be willing to add it as a contrib module, especially if that might make life easier for distro packagers. It's suboptimal though since that absolutely has to be considered techical debt that will need to be paid someday. 3. Port Mailman to pynntp (that may need to be Debian packaged, too), which has seen a revival of activity and two feature releases since 2023. My inclination as a Mailman core developer is not to participate actively in development of NNTP support in Mailman for Python 3.13+ unless we see an outpouring of support from site admins. However, I would be happy to answer questions and work on Mailman-side issues that are blocking or inconvenient for the NNTP work. Mark and Abhilash would undoubtedly contribute as well, on a time-available basis. > I certainly would love to build an alternative Mailman Debian > package that would be more up-to-date, but I don't want > to do it on my own. Debian and Python are compatible free software; just take the existing package metadata, in a recent Mailman (presumably the most recent release) drop in the most recent nntplib, and change all the import statements. mailman/src/mailman/mta/nntplib.py seems like a plausible location. IWBNI you could keep all Mailmanisms out of nntplib (because of the GPL) so any bugfixes or improvements could be available to the Python community. I think you could probably be up and running VERY quickly with that approach. Of course it wouldn't just slot into the next iteration of Debian because they have stringent QA (or maybe that could go into unstable?). I'm pretty sure it would be useful right away to a whole lot of people who are willing to use a PPA. Regards, Steve

Pck files stuck in out queue
by Lieuallen, Thomas Otis Feb. 10, 2025

Feb. 10, 2025

Running Mailman 3.3.10 I have 11x pck files stuck in my out queue. There tends to always be a .bak file as well. If I run ‘ls -l’, the files are continually updated and rotated through, just as fast as I can look. The out runner is consuming copious CPU time. I was hoping this would help: [logging.runner] level: DEBUG But, if so, I don’t see the logs anywhere. I believe they’re all for one list. When I use ‘strings’ on one to get a hint of what’s inside, I see the list members at the bottom (recipients). One of them consistently has ‘!’ before their email address. Not sure if that’s a clue. Just no other reason to suspect that, though. Ideas on where/how to track down the status of these files and fix whatever’s broken? Thank you Tom Lieuallen Oregon State University

How to limit numbers of outgoing emails per connection
by Alain D D Williams Feb. 10, 2025

Feb. 10, 2025

Exim tells me "no immediate delivery: more than 30 messages received in one connection" The emails then sit in the exim queue until a queue runner kicks in - which happens once every 30 minutes. The result is considerable delays which makes list email conversations bouncy. Question: how do I tell MM3 to send no more than 30 emails in one connection to exim (via SMTP to localhost port 25) ? If that is not possible, how do I find the number that MM3 batches outgoing emails so that I can configure exim to match (as I did with MM2) ? I see documentation pages like the following. They are useless to me, incomprehensible without a lot of learning. I program in several languages but only a little Python. What I am looking for is a setting in a config file. https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/runners/do… -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

User with abo to list can not set to another moderation flag
by Chris Feb. 8, 2025

Feb. 8, 2025

Hi again, I've one weird problem. I've some lists and a user which is a moderator on both lists. Steps to reproduce Postorius -> Users -> search for the user to change -> manage Both Lists are shown Moderarion Flag on a newer List was changed from standard to accept -> On the older list I've tried from Standard to Accept -> click on the button to accept changes result in reverting to "standard" (the setting which I want to change). Any hints on that? (can't find any difference between those lists except name und descriptions. )

How to add new Domain?
by c.benner＠apd-it.eu Feb. 7, 2025

Feb. 7, 2025

Hello, i'm really new to mailman3 and I've been using mm2.1 couple of years. It's really hardto understand documentation. But I'll do one in german language next time. I've got it installed ob Debian12 and it's working now. It takes a little more time to understand all settings and also the difference between postorius and django and what is when used for. But what I do not understand 'til now is how to add a new domain. My running config has one domain (e.g.) testdomain1.org and everything is working fine. The Domain has a virtualhost which listens on *:443 (with LE cert) Postfix works like a charm. The interface of the machine is bound to one IP Address public but for example here written as: 192.168.200.15 Id like to add a new Domain. My first step would be to add another IP Address to the interface: (e.g.) 192.168.200.16 Then I'll change the virtual host settings in apache conf from first domain which is actually listeing to *:443 to 192.168.200.15:443 And add a second site with 192.168.200.16:443 So the "physical" part is done Is that right 'til now? After that I'll go to the admin page xxxx/mailman3/admin which brings django admin page up. On that page I'll add "websites" and add testdomain2.net Last step is adding "mail domain" site: testdomain2.net mail domain: testdomain2.net After that I can add lists to that domain and mails to any list @testdomain2,net should be routed right? Maybe I'm to old (56yrs) but I've read a lot of documentation and everything was clear and understandable. It was never a question of linux or windows OS but on who'S writing the doc. I can't find any doc about the web part? What about Users having no acces to the shell but the Web-Frontend? Some pictures and a "How to" and "what if" would be great! But it's alos possible that I'm not finding it and it's somewhere out there. Thanks in advance.

Error while mass operation, no progress display while mass operation is running
by Markus Grandpré Feb. 7, 2025

Feb. 7, 2025

Dear List, At the University of Konstanz we have mailing list administrators who frequently add and remove up to 10000 (and sometimes more) list members. I have therefore tested the “Mass subscription” and “Mass removal” operations and found that both the “Remove ALL members” operation and the “Mass subscription” operation report an internal server error on the website, but continue to run in the background until all new members have been successfully added or deleted. Unfortunately, I have not found any error message in the log files. I also tested that mass operations “Remove listed users” and “Remove Selected” ran successfully and without any errors. Regardless of whether a mass operation process runs without errors or continues to run despite an error, I find it hard that Postorius does not display the progress of such a mass operation in order to monitor the process, as mass operations with more than 1000 members are very time-consuming. Perhaps this could be changed in a future version of Postorius?

Which folder should I share between pods with kubernetees persistentVolumeClaim ?
by antoine.depoisier＠ikmail.com Feb. 7, 2025

Feb. 7, 2025

I use mailman with kubernetees, and I have four pods. I currently use persistentVolumeClaim for two folders in the mailman configuration "cache" and "messages". I share these folders, as mailman needs to be consistent for these two folders, but I'm wondering if I should share other folders as well, like locks and such. There are all the folders in mailman archives cache data etc lists locks logs master.pid messages queue templates I ask this question because I often have a problem when creating a mailing list. I think I have a problem with the locks, but I'm not sure if the problem is due to the fact that the locks folder is not shared. If you want more details, here's the trace I sometimes get, when someone tries to create a mailing list: File "falcon/app.py", line 365, in falcon.app.App.__call__ File "/usr/lib/python3.12/site-packages/mailman/rest/lists.py", line 322, in on_post mlist = create_list(**validator(request)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/mailman/app/lifecycle.py", line 102, in create_list call_name(config.mta.incoming).create(mlist) File "/usr/lib/python3.12/site-packages/mailman/mta/postfix.py", line 96, in create self.regenerate() File "/usr/lib/python3.12/site-packages/mailman/mta/postfix.py", line 106, in regenerate with Lock(lock_file): ^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/flufl/lock/_lockfile.py", line 467, in __exit__ self.unlock() File "/usr/lib/python3.12/site-packages/flufl/lock/_lockfile.py", line 417, in unlock raise NotLockedError('Already unlocked') flufl.lock._lockfile.NotLockedError: Already unlocked When I check the lock folder, I have these two files, and I'm wondering if I should delete these two files : -rw-rw---- 2 mailman nogroup 97 Feb 6 2025 master.lck -rw-rw---- 2 mailman nogroup 97 Feb 6 2025 master.lck|mailman-core-deployment-5f59557b66-bkkf4|16|4268829230172994873 Do you have any answer for me ?

One-click unsubscribe?
by Jered Floyd Feb. 5, 2025

Feb. 5, 2025

I'm having a lot of problems with GMail delivery due to lack of "one-click unsubscribe" -- however that is quantified, which is not clear. In particular, there is an issue with the fact that Google ignores dots in email addresses. So I have many (MANY!) subscribers who try to use the List-Unsubscribe header target, but because they are subscribed as "idiotsubscriber(a)gmail.com" rather than "idiot.subscriber(a)gmail.com" (which they have since changed their sender to) they get a reject that they are not subscribed. These people are also far too unobservant to read the footer of every message that reads "You are subscribed as idiotsubscriber(a)gmail.com". Is there any way to provide personalized List-Unsubscribe header links, or have Mailman ignore dots in gmail.com addresses... or... anything? I'm finding reported spam percentages in the Google Postmaster Dashboard exceeding 0.1%, which causes massive delivery blocking to GMail-based subscribers. While I would gladly ban everyone who uses gmail, that sadly accounts for about half of the Internet today and would be incredibly unproductive. Thanks, --Jered

Moderation action "None" is misleading
by Markus Grandpré Feb. 5, 2025

Feb. 5, 2025

Dear List, I find the use of the term 'None' (or 'Kein' in the German translation; see attachments) in the 'Moderation action' column of the member list misleading, as the term suggests that no moderation action is applied to the respective member. However, this is not necessarily the case. If you check a member’s "Administration options / Moderation" setting, a moderation action, such as "Moderation" or "List default", may be in effect. I suggest that the 'Moderation action' column should display the currently set value of the 'Administration options / Moderation' setting for each member. Since some of our mailing lists frequently add and remove thousands of members, manually adjusting this setting for each member would not be practical.

The paradox of VERP probe messages
by Jeremy Stanley Feb. 2, 2025

Feb. 2, 2025

tl;dr: Is there a way to have VERP probe messages not include copies of the bounce message that triggered them? Longer form... Some months ago I turned on bounce processing for a fairly large list with a long history, because I could see from the MTA logs that there were easily hundreds of old subscribers whose addresses had become defunct and this seemed like a great way to clean that up and make the server more conscientious at not repeatedly trying to deliver messages to sites that were just going to reject them. This worked really well. Until legitimate subscribers also started to get removed, that is, due primarily to false positives from overzealous spam filters. I had previously read about MM3's VERP probe message feature, which seemed to solve the main reason I had kept bounce processing disabled in the MM2 days, and thought it was on by default but clearly it wasn't. So I found the necessary config option and switched that on. This worked really well. Until legitimate subscribers started to get removed again, that is, due primarily to false positives from overzealous spam filters. See, I realized that the VERP probes were helpfully including copies of the most recent bounce for that user, and those NDRs quite often helpfully included their own copies of the messages which had been bounced. So if a subscriber's MTA was rejecting a message because the content looked like spam, then there was a good chance it would also reject the VERP probe message because it included the same content which had caused the earlier rejection. The VERP probe feature was essentially defeating its own purpose as a neutral confirmation that the subscriber hadn't been rejecting messages due to their content. This behavior raises a more significant concern as well. The MTA on the Mailman server in this case (Exim if it matters) wants to perform batch deliveries when there are multiple subscribers who all share the same remote MTAs. If multiples of those reject a list post, then the NDR back to Mailman aggregates those multiple rejections into a single message. If that incident triggers a VERP probe, the bulk NDR enumerating the addresses of all the subscribers who were rejected gets forwarded along as part of the VERP probe, disclosing a potentially sensitive litany of random subscriber addresses to other subscribers within that batch. I don't know whether this is a misconfiguration, or an unintended consequence of the intersection of Mailman and MTA features. While I understand that the inclusion of a bounce sample within a VERP probe may be a way to take some workload off list admins in that users can possibly see a message/rejection to explain the reason for the probe, the downsides of that choice make the feature unfortunately unusable for some lists that could otherwise have benefited from it. Am I possibly missing an existing switch that could make VERP probe messages *not* include copies of the bounces that triggered them? This is in some ways similar to the problems I've noticed with message hold notifications to moderators including copies of the held messages, since these are (at least in the case of the lists I manage) often spam, so has a tendency to cause the mail providers for the list moderators to start considering the mailing list server a spam source. If there were a switch to make message hold notifications to moderators *not* include copies of the messages themselves, I'd start allowing moderator notifications again. Suggestions welcome! Also willing to try to submit patches to enable some of these solutions if they don't already exist. And thanks to anyone who read this far! -- Jeremy Stanley

Outgoing runner lockup? + "slice inspector" tool
by Stephen J. Turnbull Feb. 1, 2025

Feb. 1, 2025

Hi, I'm advising a user on a system which experiences occasional lockups in an outgoing runner. The runner contacts a remote smarthost, and occasionally locks up with the smtp connection still open according to "lsof -i :25". This state seems to be permanent: the backlog for that slice starts to grow without bound, for at least an hour. When this was happening once a month, they would just restart Mailman core, and the backlog would clear in minutes. But recently it's been happening daily which is distracting their staff, and worries me. Another thing that is strange about this site is that it should be possible to hit that runner with a SIGUSR1 and restart it. This works for me, but on that system the stuck runner exits, but does not restart. Since normally it only happens to one runner of several, I wanted to identify the runner and process. I attach the tool I developed, for anyone who might have configured multiple runners and is interested to see the distribution across runners. Has anybody seen an outgoing runner lock up with an open smtp session? Any ideas on why? My analysis so far: - Because a restart works every time, I'm pretty sure it doesn't have anything to do with message content. - I believe both the Mailman host and the outgoing smarthost are Linodes, in the same datacenter. The problematic Mailman system is Mailman 3.3.6, Python 3.10 on Ubuntu 16.xx LTS. I believe the smarthost is a more recent Ubuntu LTS, probably running Postfix 3.7 as the MTA. (Yes, they have sufficiently paranoid security and QA teams. ;-) - We're using smtplib, which as far as I can tell basically has a 60s timeout for each command. Thus you'd think it would time out. I guess it could be inflooping on timeout, retry, timeout, retry, but I don't know how to check that. Maybe ss(8) will serve? - My system where SIGUSR1 works as documented is Python 3.11.2 on a Digital Ocean droplet with Debian 12.9, Linux 6.1.0. - I haven't tried to reproduce the Python 3.10 + Mailman 3.3.6 configuration and test SIGUSR1 in that configuration yet. Seems unlikely, waiting for the proverbial "round tuit". - It has occurred to us to use the local Postfix as the relay MTA. I'm waiting on a report whether that alleviates the problem. Even if so, I want to fix the underlying defect if possible. Any ideas would be welcome, including general debugging advice. Here's the promised slice_inspector tool. (Patches and suggestions welcome, though I don't promise to implement any time soon.) The tool imports some files from Mailman core, click, and psutil (not psutils!) I believe the latter modules are required by Mailman, so you should be able to run it as is under the 'mailman' user (or perhaps 'list' on Debian) in the environment Mailman itself uses. It defaults to assuming that mailman.cfg is /etc/mailman3/mailman.cfg. You'll probably need to fix the shebang if you want to chmod +x. The '--help' should be pretty self-explanatory. Steve

messages with attachments, without text discarded silently
by Schulz Feb. 1, 2025

Feb. 1, 2025

Using the current mailman version, I can reproduce the following: - send a text-formatted email with attachment but without text body to a list. - the msg will be received by mailman - the msg shows up in shunt, the log shows: ile "/usr/lib/python3.12/email/message.py", line 343, in set_payload payload = payload.encode(charset.output_charset, 'surrogateescape') ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ UnicodeEncodeError: 'ascii' codec can't encode characters in position 10-17: ordinal not in range(128) an attempt to unpickle the file leads to the same error. I know it's uncommon to send emails without txt but with attachments - but it may happen; at least we would welcome an error message.

Hello, occasionally we face the problem "The content of this message was lost." when handling a message on hold.

I have tried to find an equal issue, but could not find it. If so, sorry for the doubling... I have recently setup a fresh mailman3 installation on my debian12 box. It works fine.

Adding Mass Subscribe custom template error
by Arte Chambers Jan. 29, 2025

Jan. 29, 2025

I am trying to test some different templates however after adding a new template I get an error when adding new list members. The member is added to the list however the welcome message isn't sent to the user. I'm getting the following error when using mass subscription on a testing list with a custom template loaded for [list:user:notice:welcome] ``` HTTP Error 400: HTTPConnectionPool(host='localhost', port=8000): Read timed out. (read timeout=5) ``` The template has the text "Testing Template" I'm not sure why it's timing out but when I remove the custom template it works as expected. The user is added to the list however doesn't get the custom welcome message. mailman.log: ``` [28/Jan/2025:20:22:47 +0000] "GET /3.1/lists/ testing.list.louisvillecommunitygrocery.com HTTP/1.1" 200 482 "-" "GNU Mailman REST client v3.3.5" Jan 28 20:22:52 2025 (1977989) deque: Traceback (most recent call last): File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/connectionpool.py", line 536, in _make_request response = conn.getresponse() ^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/connection.py", line 507, in getresponse httplib_response = super().getresponse() ^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/http/client.py", line 1428, in getresponse response.begin() File "/usr/lib/python3.12/http/client.py", line 331, in begin version, status, reason = self._read_status() ^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/http/client.py", line 292, in _read_status line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/socket.py", line 707, in readinto return self._sock.recv_into(b) ^^^^^^^^^^^^^^^^^^^^^^^ TimeoutError: timed out The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/opt/mailman/venv/lib/python3.12/site-packages/requests/adapters.py", line 667, in send resp = conn.urlopen( ^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/connectionpool.py", line 843, in urlopen retries = retries.increment( ^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/util/retry.py", line 474, in increment raise reraise(type(error), error, _stacktrace) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/util/util.py", line 39, in reraise raise value File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/connectionpool.py", line 789, in urlopen response = self._make_request( ^^^^^^^^^^^^^^^^^^^ File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/connectionpool.py", line 538, in _make_request self._raise_timeout(err=e, url=url, timeout_value=read_timeout) File "/opt/mailman/venv/lib/python3.12/site-packages/urllib3/connectionpool.py", line 369, in _raise_timeout raise ReadTimeoutError( urllib3.exceptions.ReadTimeoutError: HTTPConnectionPool(host='localhost', port=8000): Read timed out.

mailman3-web postorious error "invalid request block size: 14056 (max 4096)...skip"
by Frederik Jan. 28, 2025

Jan. 28, 2025

Until about one month ago, I had mailman3 and mailman3-web successfully running on Debian 12. However, when I access any page such as https://example.com/mailman3/postorius/lists/ now, I just get a 500 server error. /var/log/mailman3/web/mailman-web.log logs this at every request: invalid request block size: 14056 (max 4096)...skip I read somewhere that adding buffer-size = 65536 to uwsgi.ini might help. It indeed makes a difference, but unfortunately I just get another error instead: [pid: 4067215|app: -1|req: -1/1] () {256 vars in 14055 bytes} [Tue Jan 28 18:06:30 2025] => generated 0 bytes in 0 msecs ( 500) 0 headers in 0 bytes (1 switches on core 0) There are no other errors in the logs. I proxy mailman in Apache like this: Alias /mailman3/favicon.ico /var/lib/mailman3/web/static/postorius/img/favicon.ico Alias /mailman3/static /var/lib/mailman3/web/static <Directory "/var/lib/mailman3/web/static"> Require all granted </Directory> <IfModule mod_proxy_uwsgi.c> ProxyPass /mailman3/favicon.ico ! ProxyPass /mailman3/static ! ProxyPass /mailman3 unix:/run/mailman3-web/uwsgi.sock|uwsgi://localhost-mailman3/ </IfModule> and mailman3's uwsgi.ini looks like this: [uwsgi] uwsgi-socket = /run/mailman3-web/uwsgi.sock enable-threads = true chdir = /usr/share/mailman3-web wsgi-file = wsgi.py master = true process = 2 threads = 2 uid = www-data gid = www-data env = HOME=/tmp plugins = python3 attach-daemon = python3 manage.py qcluster logto = /var/log/mailman3/web/mailman-web.log buffer-size = 65536 Any idea what could be wrong or how to debug this further? I'm using mailman3-full 3.3.8-2~deb12u2 and mailman3-web 0+20240312-1 packages.

Filter response from Mailman3 held messages queue.
by Andy Matthews Jan. 28, 2025

Jan. 28, 2025

I'm working on an update to a portion of my team's application. It retrieves the held messages from Mailman and returns them to the client so that our admins can approve/reject them. At the moment it works as intended, but displays far too much information because Mailman is returning the entire email, with headers (see below). I've found some libraries which can parse the message property and extract the relevant bits, but I'd rather pass some sort of flag or filter to the initial Mailman 3 API call and get back less information. I've looked through the documentation but I'm not finding anything of the sort. Would this be useful? ``` { "request_id": "1", "original_size": 855, "sender": "dev(a)email.org", "subject": "Testing one two three", "hold_date": new Date(), "msg": "Received: from [127.0.0.1] (localhost [127.0.0.1])\n\t(using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits)\n\t key-exchange X25519 server-signature RSA-PSS (2048 bits) server-digest SHA256)\n\t(No client certificate requested)\n\t(Authenticated sender: dev(a)email.org)\n\tby mailman.default.svc.cluster.local (Postfix) with ESMTPSA id A48A33E9849\n\tfor <abc-announce(a)email.org>; Thu, 23 Jan 2025 21:24:11 +0000 (UTC)\nMessage-ID: <3ecbaccf-f65a-4ce5-bdfa-e08b5659dc32(a)email.org>\nDate: Thu, 23 Jan 2025 15:24:11 -0600\nMIME-Version: 1.0\nUser-Agent: Mozilla Thunderbird\nContent-Language: en-US\nTo: abc-announce(a)email.org\nFrom: Dev Tester <dev(a)email.org>\nSubject: Testing one two three\nContent-Type: text/plain; charset=UTF-8; format=flowed\nContent-Transfer-Encoding: 7bit\nX-MailFrom: dev(a)email.org\nX-Mailman-Rule-Hits: nonmember-moderation\nX-Mailman-Rule-Misses: dmarc-mitigation; no-senders; approved; emergency; loop; banned-address; member-moderation\nMessage-ID-Hash: XM4OS47LU7DRYIO74WB5K4W345NPZ37O\nX-Message-ID-Hash: XM4OS47LU7DRYIO74WB5K4W345NPZ37O\n\nThis is a single line message body.\n\n" } ```

Mailman3 breaking DKIM signatures
by Jef Driesen Jan. 24, 2025

Jan. 24, 2025

Hi, I have configured a mailman3 mailinglist to not modify the headers and body (e.g. no footer, no subject prefix, etc) to avoid breaking DKIM signatures. This worked well, until I encountered an email where the DKIM signature was still broken. After some debugging, the problem is caused by an attachment, where the mime header is changed by mailman3. The original mail contains this: --------------nYYjj8vJ8CNKuoHJZKVOQh20 Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; name="filename.xlsx" Content-Disposition: attachment; filename="filename.xlsx" Content-Transfer-Encoding: base64 Mailman3 modified these into this: --------------nYYjj8vJ8CNKuoHJZKVOQh20 Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; name="filename.xlsx" Content-Disposition: attachment; filename="filename.xlsx" Content-Transfer-Encoding: base64 The Content-Type header is modified (word-wrapped), and this breaks the DKIM signature. How can I prevent this from happening and configure mailman to not modify the email? Jef

Python 3.13 compatibility
by peter＠chubb.wattle.id.au Jan. 24, 2025

Jan. 24, 2025

Hi Folks, I'm running the Debian-packaged mailman3 (version 3.8) which is a little behind the current 3.9 release ... Debian is now shipping Python 3.13 in 'sid'. https://docs.python.org/3/whatsnew/3.13.html#id4 says: Remove the ability to use Path objects as context managers. This functionality was deprecated and has had no effect since Python 3.9. (Contributed by Barney Gale in gh-83863.) As a result, I'm hitting tracebacks from many operations where pathlib.Path objects are used as context managers, like this one: path, fp = find(default_uri, mlist, code) ~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/mailman/utilities/i18n.py", line 157, in find for search_path in raw_search_order: ^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-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 Given that the python3.13 change is only to move a noop to an exception, it may be that this is a bug for python 3.9 and up as well.

Hello Everybody, i have set up a fresh mailman3 installation with maxkings Docker compose image (https://github.com/maxking/docker-mailman) I've got it working except i get a very strange hyperkitty error: Each time i'm sending a post to the list, it gets distributed to the emailadresses of the list, and at the same time i'm geting a bunch of error Mails. And: There are no Mails visible in the Archive. The directory under core/var/archive/hyperkitty/spool/ listst the mails....though... Hyperkitty-Api-Key in the docker-compose.yml is set via .env Variabel, so it should be identical. That ist the error Mail i receive: Can annybody hint me where to search further, what is wrong?

API web hook for subscribe and remove user
by Tibor Molnar Jan. 22, 2025

Jan. 22, 2025

Hi there, I'm looking to find out if there is any way of deleting a user over API and what config needs to be done. Also if I can subscribe user/ users over API to lists. I'm aware that I can remove users in cli mailman shell, so I want to do the same thing over the web. I'm also aware that mailman3 is already query API on localhost and that's how it's generating the output for system information but if I was going to configure it for remote where else other than mailman.cfg do I need to configure this? My current version is: Mailman Core Version GNU Mailman 3.3.8 (Tom Sawyer) Mailman Core API Version 3.1 Related conf in mailman.cfg: [webservice] hostname: localhost port: 8001 use_https: no admin_user: restadmin admin_pass: Thank you for your help

I can use email to get a list of members: To: mylist-request(a)lists.theserver.org Subject: who (password) Any chance that a sync_members could be accomplished in a similar fashion? Looks like it's only available from the console, but I'm asking anyway to be sure. Thanks.

Fix, kind of, of 'Internal Server Error'
by Alain D D Williams Jan. 20, 2025

Jan. 20, 2025

I was getting several thousand error messages a day complaining about this. I would also find that the web interface would time-out/die - going away to make a cup of tea was the only things to do -- ie just wait. I am getting far fewer of these today after I tweaked by robots.txt. The problem was search engines (and maybe AI monsters) crawling the site and over loading it. The machine has 1.5GB of RAM & plenty of fast (SSD) swap. It copes well enough except when the crawlers come in. So, 2 fixes: Crawl-delay: 10 Do not visit more frequently than every 10 seconds. Google ignores this as it expects you to waste time on their search console. Disallow: /mailman3/ Do not visit at all. However if you do this then archives will not be indexed. All that I can say is: works for me, I have 1% of the errors that I had previously. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

Hi, is there a way to search lists in Postorius' Lists overview https://lists.example.com/mailman3/lists/?all-lists Well, one can change "results on page" to 200 and then use the search function of the browser, but that is some more clicks. -- Mit freundlichen Gruessen, Andreas Vetter

Random lmtp Timeout and Long Message Processing times
by Taber, Douglas R Jan. 9, 2025

Jan. 9, 2025

Hello- We’re seeing a seemingly random issue with message acceptance on our mailman instance where some messages sent from postfix to the lmtp listener timeout. It’s not consistent to any specific list or time of day, and messages are accepted on the next attempt by postfix to deliver the message to the lmtp. Additionally, there seems to be a similarly random delay in accepting and processing messages before they are sent to the list moderators or list members.

Feature request, hyperkitty, low volume lists
by Alain D D Williams Jan. 9, 2025

Jan. 9, 2025

I host several low volume mail lists. Typically these are announcement lists where low volume is deliberate -- too many emails and people might unsubscribe. These lists are archived but most months there are not any postings. Browsing the archives can mean much clicking to find content, this is done better with mailman2. My request is to make finding content easier. Possibilities: • On the summary (left hand side) put the number of posts after the month name • Only show months (left hand side) where there are any posts For an example see: https://fridayfolk.phcomp.co.uk/mailman3/hyperkitty/list/announce@fridayfol… (There is one post in November) Regards -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

Jan. 6, 2025

Hi As a moderator I receive an email each day for "Held Unsubscriptions" for a subscriber that was unsubscribed by the Owner sometime ago (using "Mass operations"). +++++++++++++++++++++++++++++++ The listname(a)domain.com list has 1 moderation requests waiting. Held Unsubscriptions: User: bart(a)example.com Please attend to this at your earliest convenience. +++++++++++++++++++++++++++++++ There is nothing showing under "Subscription requests > Pending approval". Could anyone tell me how I can stop these email notifications? I have access to the mailman shell and the databases. Thanks, Mark

possible backscatter attack using Mailman3 servers
by David Newman Jan. 5, 2025

Jan. 5, 2025

Greetings. On a system running Mailman 3.3.9 and Postfix, I'm seeing about 20-30 entries per day in the Postfix queue where it appears a Gmail user signs up for a mailing list that requires confirmation, and Gmail responds that the user is too busy to handle requests. There are no publicly advertised email lists on this server, and I don't ever see anything in the Mailman logs indicating the user ever tried signing up. I've pasted the mail.log transaction below, with only slight obfuscation: - "mail10.example1.com" is this server's canonical hostname - lists are hosted on "lists.example2.com" and "mail.example3.com" - "someuser9413(a)gmail.com" is the user supposedly signing up Thanks in advance for clues on determining where these requests are coming from, and how I might block them. I have a strong interest in having my server not amplifying backscatter traffic like this. Alternatively, if this is a Postfix problem, please let me know that too. dn Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: CONNECT from [::1]:55274 to [::1]:25 Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: WHITELISTED [::1]:55274 Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: using backwards-compatible default setting respectful_logging=no for client [::1]:55274 Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: connect from localhost[::1] Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: discarding EHLO keywords: CHUNKING Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: 4YPsYG1X2xzHQfw: client=localhost[::1] Jan 3 10:29:22 mail10 postfix/cleanup[4052628]: 4YPsYG1X2xzHQfw: message-id=<173592896219.2314.15515568084960961396(a)mail10.example1.com> Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: disconnect from localhost[::1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG1X2xzHQfw: from=<postmaster(a)example2.com>, size=901, nrcpt=1 (queue active) Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: connect from localhost[127.0.0.1] Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: discarding EHLO keywords: CHUNKING Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: 4YPsYG33SkzHSdN: client=localhost[127.0.0.1] Jan 3 10:29:22 mail10 postfix/cleanup[4052628]: 4YPsYG33SkzHSdN: message-id=<173592896219.2314.15515568084960961396(a)mail10.example1.com> Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG33SkzHSdN: from=<postmaster(a)example2.com>, size=1939, nrcpt=1 (queue active) Jan 3 10:29:22 mail10 amavis[4017234]: (4017234-09) Passed CLEAN {RelayedInternal}, MYNETS/MYUSERS LOCAL [::1]:55274 ESMTP/ESMTP <postmaster(a)example2.com> -> <someuser9413(a)gmail.com>, (), Queue-ID: 4YPsYG1X2xzHQfw, Message-ID: <173592896219.2314.15515568084960961396(a)mail10.example1.com>, mail_id: P9P7GnranpAW, b: Zp0DirpBL, Hits: -, size: 900, queued_as: 4YPsYG33SkzHSdN, Subject: "[mail.example3.com] Please Confirm Your Email Address", From: <postmaster(a)example2.com>, helo=mail10.example1.com, dkim_new=dkim:example1.com, 217 ms Jan 3 10:29:22 mail10 postfix/amavis/smtp[4052633]: 4YPsYG1X2xzHQfw: to=<someuser9413(a)gmail.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.24, delays=0.02/0/0.01/0.21, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 4YPsYG33SkzHSdN) Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG1X2xzHQfw: removed Jan 3 10:29:22 mail10 postfix/smtp[4052642]: Trusted TLS connection established to gmail-smtp-in.l.google.com[2607:f8b0:4023:c0d::1b]:25: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature ECDSA (prime256v1) server-digest SHA256 Jan 3 10:29:22 mail10 postfix/smtp[4052642]: 4YPsYG33SkzHSdN: host gmail-smtp-in.l.google.com[2607:f8b0:4023:c0d::1b] said: 450-4.2.1 The user you are trying to contact is receiving mail at a rate that 450-4.2.1 prevents additional messages from being delivered.

mailman transfer from 2to3
by Daniel Germer Dec. 28, 2024

Dec. 28, 2024

Hello all, I am new to mailman3, once upon a time I had mailman installed on my server, but had trouble with many things, especially virtual hosts not possible in mailman2... However on https://docs.mailman3.org/en/latest/pre-installation-guide.html#what-do-i-n… are no system requirements for the installation. I assume, that I cannot just install mailman3 on a regular webhoster, but there is no section: You need to have root access to a Linux system with at least 8/16/31/64GB RAM and at least 1/2/5/7 GB of free diskspace (ssl or hard-disk?) You need so and so much for 100/1000 Lists with 10/100/1000 Users each and 5/50/500 Mailings per day... where do I find that information? what is the smallest possible machine to run mailman3 on? Can I run it on a raspberry pi? regards, Daniel

Dears, I am currently cleaning up a huge list of non-members. In contrast to the members list where I can select multiple entries and delete them at once, this is not possible in the list of non-members? Can this be enabled in a future release? Thank you and kind regards Torge

I've got a new installation of Mailman 3 setup, however I am having some issues I'm not sure how to troubleshoot.

Suggestion on Mailing Lists page
by Alain D D Williams Dec. 24, 2024

Dec. 24, 2024

This is the page that lists the mailing lists that I have. It would be really useful if there was an indication next to each list if that list required attention, eg an email awaiting moderation. Have a good Xmas everyone. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

MM2 to MM3 Archives Loading
by Joshua Bushe Dec. 22, 2024

Dec. 22, 2024

Hi everyone, I’ve successfully converted a list from Mailman 2 to Mailman 3, and most things are working smoothly. However, I’m encountering an issue with the archives in the GUI: Problem: The archives don’t load on the overview page. Odd Behavior: If I use the search function, the archives appear as expected, but they remain invisible on the main overview. Has anyone encountered this issue or have suggestions for troubleshooting? Thanks in advance for your help!

Flooded non-members with "prvs=<number>=<mail>"
by Torge Riedel Dec. 22, 2024

Dec. 22, 2024

Dears, I checked the non-members list of all my mailman3 lists and found a lot entries like "prvs=<number>=<mail>", the <mail> is always an address from @freenet.de A quick research mentions something related to bouncing and that such mails should be blocked/filtered. But no further details. Can you give a hint where I need to change what to block such mails and avoid that such entries floods the non-members list? Thank you and kind regards Torge
