Trouble Installing Mailman3
by Henry Hartley June 6, 2025

June 6, 2025

I'm having problems installing mailman3 following the instructions on https://docs.mailman3.org/en/latest/install/virtualenv.html Everything goes well until I get to the Installing Mailman Core<https://docs.mailman3.org/en/latest/install/virtualenv.html#installing-mail…> step, which has me do the following in my venv environment: (venv)$ pip install wheel mailman psycopg2-binary Ubuntu 24.04.02 LTS Python 3.12.3 pip version 24.0 First, I was getting problems because my company firewall was blocking outbound traffic. I got that taken care of. Next, I was seeing certificate errors, saying there was a self-signed certificate: WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1000)'))': /simple/wheel/ Could not fetch URL https://pypi.org/simple/wheel/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/wheel/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain (_ssl.c:1000)'))) - skipping When I added --trusted-host pypi.org that error went away but I'm still unable to install anything: (venv) mailman@wz-prd-tpmd-1:~$ pip -v --trusted-host pypi.org install wheel mailman psycopg2-binary Using pip 24.0 from /opt/mailman/venv/lib/python3.12/site-packages/pip (python 3.12) ERROR: Could not find a version that satisfies the requirement wheel (from versions: none) ERROR: No matching distribution found for wheel The same error shows up if I try to install just mailman or psycopg2-binary, except the word "wheel" is replace with whichever package I've requested. I've rerun the apt install of python3-dev and python3-venv to make sure those are present and up to date. Any help you can provide will be greatly appreciated. -- Henry Hartley Westat

Threads by month dropdown
by Sam Darwin June 5, 2025

June 5, 2025

Hi, After running hyperkitty_import to import thousands of emails from mailman2 (the years 2013-2025) I then ran another import for years 2004-2013 from another mbox file. It was an entirely earlier timeframe, which may be relevant. After the first import, the "Threads by month" dropdown showed 2013-2025. After the second import, the "Threads by month" dropdown showed 2013-2025. That is, 2004-2013 are missing. I have tried various things, including the mailman3-web cron maintenance tasks, waiting a day, and rebooting the server to clear memory. All messages were imported, and can be seen in "All threads". The messages are there. The only problem is the "Threads by month" dropdown. Beyond the dropdown, everything seems fine. Could it be a bug? Should I open an issue? Or, what should I try next? Is there a "refresh all threads by month" specific task? Deleting all archives and importing the older messages first... that worked correctly. It is a large destructive actions though, should that count as the official solution? Detour: While debugging it seemed to be an interesting question whether the mailman3-web periodic cron tasks had been running, and if those tasks affected the hyperkitty import. Referring to "Cron Jobs for Mailman Web" https://docs.mailman3.org/en/latest/install/virtualenv.html#cron-jobs-for-m… Those instructions are not dumping stdout/stderr to a log file, nor rotating the log files. What is your opinion if I sent a pull request that adds "Method 2 - Advanced", and include logging for the crons. Or maybe I am missing something. Is the output of the cron tasks getting logged in your environment?

Recently active discussions - Hyperkitty
by Sam Darwin June 5, 2025

June 5, 2025

Hi, Sometimes not sure if it's preferable to open a gitlab issue, or chat on the mailing list. I have run a large archive import into mailman3/hyperkitty. After that's done, waited a day, for scheduled cron jobs to complete. In "All Threads", all the email archives are present. The import worked. In "RECENTLY ACTIVE DISCUSSIONS" on the main page, it says: RECENTLY ACTIVE DISCUSSIONS No discussions this month (yet). Nothing there. That means if I direct users to visit the site, the page, it appears empty. That's too bad. :-) It should display recent emails. What would affect this feature during an archive import? Is it a problem with the import script itself, or with a scheduled cron job, or something else? Would you expect "Recently active discussions" be empty when very recent archives do exist? Thanks, Sam

CPU usage when idle
by roughnecks May 29, 2025

May 29, 2025

Hello, if you look at this graph you'll notice how my VPS "reacted" after mailman3 install. It's a Debian stable host, and I installed packages via apt. I mean, isn't this a bit too much for a software that is idle, because no lists are currently in use? RED is my VPS, the other colors are other machines.

Unable to update templates
by Mark May 29, 2025

May 29, 2025

Hi, I'm unable to update the custom welcome template (list:user:notice:welcome) after it's initial creation. When the custom welcome template is created (in Postorius), and a user then subscribed by the list-owner (using mass subscribe), the welcome message is received as expected. However when I update the template, the databases are updated correctly but the Welcome message is still sent with the old template content. mailman.templates mailmanweb.postorius_emailtemplate Additionally, if I delete the template and create a new one the old content still gets sent. I cannot find where this content is written or is being cached. Any clues on tracking this bugbear down gratefully received.

Re: MM broken after proxy migration (Nginx -> Caddy)

Hi Stephen, thanks for the comprehensive explanations and sorry for initially not answering to the list (I expected this to be the default behaviour). Afterall it turned out that my mailman.db was somehow broken, even though I couldn't find any fishy / strange things in Postorius. Since anyhow just a few lists are hosted on the server and subscriptions for most of them being managed fron another program, I decided to remove MM3 completely and start with a fresh configuration.

Hyperkitty archive: date format in thread overview of list does not honor DATETIME_FORMAT of settings.py
by Christian Schneider May 28, 2025

May 28, 2025

Dear mailman community, with the help of you I was able to set up a new mailman3 environment (a big THANK YOU!!! :-)): OS: Ubuntu 24.04-LTS mailman: GNU Mailman 3.3.10 (Tom Sawyer) Python: 3.12.3 (main, Feb 4 2025, 14:48:35) [GCC 13.3.0] Method: Python Virtual Environment Installation My configuration files are placed in the following directory: /etc/mailman3 - gunicorn.py - mailman.cfg - settings.py The environment is up and running: A list for testing is set up and mails are transfered (and archived) using the test-list - successfully... :-) Looking at the thread overview of the list (in Hyperkitty archives) I realized that the shown date format is unusual (for Germany), like: Do Mai 22, 3:57 nachm. (meaning: Thu May 22, 3:57 p.m.) I would prefer a format like: 22-05-2025 15:57:24 So I tried to reconfigure this setting in settings.py according to this URL: https://docs.mailman3.org/en/latest/config-web.html#configure-postorius-hyp… In settings.py I set DATETIME_FORMAT to 'd-m-Y H:i:s' but the format did not change. (After changing settings.py I initiated a restart of mailman3 and mailmanweb) I also set USE_L10N to False as suggested in Django-Docs: https://docs.djangoproject.com/en/3.1/ref/settings/#std:setting-DATETIME_FO… My /etc/mailman3/settings.py is parsed - as far as I can say because changing USE_I18N to false (in /etc/mailman3/settings.py) switches date to English as this is my locales-setting on Ubuntu... Nevertheless the format stays the same (in this case: Thu May 22, 3:57 p.m.) How can I adjust the date format (in the discussion boxes) at the thread overview page (url: https://my-domain.de/archives/list/test-list@lists.my-domain.de/)? Any hint is appreciated! Thank you very much and kind regards Christian

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

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

May 27, 2025

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

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

May 27, 2025

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

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

May 24, 2025

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

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

May 15, 2025

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

Django-allauth compatibility (ACCOUNT_AUTHENTICATION_METHOD and ACCOUNT_EMAIL_REQUIRED)
by Jan Eden May 14, 2025

May 14, 2025

Hi, after installing Mailman 3 in a new virtual environment, I ran into the compatibility issues with django-allauth discussed by Andreas Vetter and Mark Sapira on this list in February[1] and in March[2] – WARNINGS: settings.ACCOUNT_AUTHENTICATION_METHOD is deprecated, use: settings.ACCOUNT_LOGIN_METHODS = {'email', 'username'} settings.ACCOUNT_EMAIL_REQUIRED is deprecated, use: settings.ACCOUNT_SIGNUP_FIELDS = ['email*', 'username*', 'password1*', 'password2*'] – and solved them with the additions to /etc/mailman3/settings.py suggested by Mark: del ACCOUNT_AUTHENTICATION_METHOD ACCOUNT_LOGIN_METHODS = {'email', 'username'} del ACCOUNT_EMAIL_REQUIRED ACCOUNT_SIGNUP_FIELDS = ['email*', 'username*', 'password1*', 'password2*'] In the second list thread, Mark linked to the current (patched) version of mailman-web's mailman.py[3], which addresses the deprecation of ACCOUNT_AUTHENTICATION_METHOD, but not of ACCOUNT_EMAIL_REQUIRED. Is there any reason why the patch fixes only one of the two issues? - Jan [1] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [2] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [3] https://gitlab.com/mailman/mailman-web/-/blob/c8b9aef1704b75b1cb6d0c925855a…

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

May 14, 2025

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

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

May 5, 2025

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

acceptable_aliases not updating venv/data/postfix_lmtp
by Stefan Bauer May 5, 2025

May 5, 2025

Dear Users, I'm trying to use acceptable_aliases for a specific list; Setting is also active; # curl -s -q --user restadmin:..... http://localhost:8001/3.1/lists/postmaster@domain/config | jq { "acceptable_aliases": [ "abuse@domain" ], However venv/data/postfix_lmtp does not contain abuse@domain, so postfix rejects the mail. What am i doing wrong? Mailman 3.3.9 Thanks in advance Stefan

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

May 1, 2025

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

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

April 28, 2025

I made a snapshot of my mailman3 VM before running a script to modify a bunch of lists. I stupidly did not turn the VM off before I made the snapshot, so Im almost certain this is a corrupted DB problem from doing a snapshot restore. The issue is now that the mailman service will not start automatically. Im able to get to the web interface but I see the error "Mailman REST API not available. Please start Mailman core." I can su to the mailman user and run 'mailman start -f' which seems to get things going again and shows the lists as they were before the snapshot, which is good, but I would like to get the issue fixed so that services start normally. Any help is appreciated. Here is some terminal output: ===================== ''' root@mlist3:~# systemctl status mailman3 × mailman3.service - GNU Mailing List Manager Loaded: loaded (/etc/systemd/system/mailman3.service; enabled; preset: enabled) Active: failed (Result: exit-code) since Mon 2025-04-28 13:24:43 UTC; 1min 39s ago Process: 1873 ExecStart=/opt/mailman/venv/bin/mailman start (code=exited, status=2) CPU: 776ms Apr 28 13:24:42 mlist3 systemd[1]: Starting mailman3.service - GNU Mailing List Manager...

Login confusion
by Markus Grandpré April 22, 2025

April 22, 2025

Dear list, We've encountered an issue with Postorius after migrating from Mailman 2.1. It appears that Postorius is treating email addresses with differing capitalization as distinct user accounts. For example, <markus.grandpre(a)uni-konstanz.de> and <Markus.Grandpre(a)uni-konstanz.de> are being recognized as separate identities. This is causing significant confusion. Users registered with one capitalization pattern are not seeing the list subscriptions and settings that were previously associated with their account (imported from Mailman v2.1) which used a different capitalization. Is there a known configuration option or method within Postorius (or Mailman 3 itself) to normalize or unify account identification, effectively treating email addresses as case-insensitive for account matching? We need a solution that ensures users see their correct list memberships regardless of the capitalization they use when logging in or that was used during the original Mailman 2.1 import. Thank you in advance Markus -- Markus Ludwig Grandpré Universität Konstanz Kommunikations-, Informations-, Medienzentrum (KIM) Abteilung IT-Dienste Forschung und Lehre, B803, Tel: ++49 7531 88 4342

Moderator e-mails only going out once a day
by jkoral＠luc.edu April 22, 2025

April 22, 2025

Hi, I have just got done migrating from MM2 to MM3 and the users are experiencing issues with their moderated messages. After the message is sent, the moderator does not know about the message until the next day. I checked the maillogs and all those messages are being sent at the same time around midnight. I also noticed the messages are being sent from user(a)example.com, which I switched in /etc/mailman3/mailman.cfg to a generic e-mail address. Is there a way to change those moderator e-mails to send right away? Does having user(a)example.com in the config affect that? Thank you in advance, Joe

Upgrade docker-mailman to v0.5.2
by Christopher April 21, 2025

April 21, 2025

Hi Abhilash, I checkout the v0.5.2 for testing my upgrade from 0.4.6 and noticed, that the docker-image-version is still set to 0.4 in docker-compose.yaml. Is there any reason for it or should it be set to 0.5? I´m still using my good old mariadb. I did not find any upgrade-informations about breaking-changes. Do you have any experience with migrating from 0.4.6 to 0.5.2 on mariadb? Best regards Chrclaus

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

April 21, 2025

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

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

April 21, 2025

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

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

April 20, 2025

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

Disabling "delete account" option
by Hitashi mancho April 19, 2025

April 19, 2025

Dear all, Recently, I have migrated from Mailman2 to Mailman3 GNU Mailman 3.3.10 (Tom Sawyer) Python 3.11.9 Some of the list users logged into Postorius and went to profile settings. Over there, they found an option "Delete Account". Without any discussion, they deleted their account and all their list membership. How can we prevent this from happening? Is it possible to disable this "Delete Account" option, or can we add some admin approval? Regards, Hitachi. ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Do you struggle with message rejected. AUP#CDRBL while using mailman with your ISP email relay?
by Michael Richardson April 18, 2025

April 18, 2025

I'm impressed by Philip Bondi's use of mailman[23] for home financial automation. ("Take off Eh!") ... It seems like a ticketing system would be a better system for such a use... maybe the IETF SML WG will further help with this.. (I find most Canadian financial institutions are so far behind the curve) I think that your email is hosted by hostedemail.com? I'm guessing that "eshop" is the mailbox you use for these common notices, and maybe you retrieve that into your mailman3 with fetchmail or something? Or does your ISP turn around and SMTP to you directly? Is it your MTA, their MTA, or mailman that is doing the rejection? My problem, on lists.sandelman.ca aka lists.tcpdump.org, is messages that appear to have been processed by my MTA (according to postfix logs), but which are never delivered, nor held. Lost somewhere in mailman3 queue. Sometimes they show up after a host reboot.

Do you struggle with message rejected. AUP#CDRBL while using mailman with your ISP email relay?
by Philip Bondi April 17, 2025

April 17, 2025

Hello to all: mailman3 is phenomenal upgrade from mailman2. Very nice. Thank you to the team. In our family, we use mailman to provide redundancy on important financial emails. In this manner, emails from banks, government, ecommerce or other important providers are distributed to multiple family members. And we can ask family members if they paid the credit card bill, received their delivery, saw their tax liability or refund notification, etc. Does anyone else use mailman for such a purpose? Do you struggle with "message rejected. AUP#CDRBL" while using mailman with your ISP email relay? For example, when receiving email from a Bank or the Government of Canada on a mailman2 list, sometimes my ISP would not relay the email and I would get message rejected. AUP#CDRBL On mailman2, I mitigated by stripping headers, wrapping message and DKIM signing. Here is a mailman2 message that is stripped, wrapped and signed. https://freeimage.host/i/30O5EXe Do you have this problem with your ISP with certain senders? What are your mitigation strategies on mailman3?

makemigrations --merge error after Debian upgrade
by Chupin Maxime April 16, 2025

April 16, 2025

Hi, I upgraded my debian version, and since, it seems that I have a problem. I tried `mailman-web migrate` (and `mailman-web collectstatic` etc.) and I get the error message: ``` CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0010_auto_20220618_2315, 0014_schedule_cluster in django_q; 0014_auto_20220618_2315, 0018_alter_emailtemplate_language in postorius). To fix them run 'python manage.py makemigrations --merge' ``` So I tried `mailman-web makemigrations --merge` that ended with ``` PermissionError: [Errno 13] Permission denied: '/usr/lib/python3/dist-packages/postorius/migrations/0019_merge_20240930_1159.py' ``` There is no such a file in the migration directory. Any idea ? Thanks in advance, All the best Maxime Chupin

how should I implement multiple domains for receiving emails to a list
by Philip Bondi April 16, 2025

April 16, 2025

Hello to all: I think I have resolved almost all of my issues. Thank you for your coaching. You are all super heroes. I have two domains: systemdatabase.ca, systemdatabase.homelinux.com All my lists should be on both domains. So h(a)systemdatabase.ca is the same list as h(a)systemdatabase.homelinux.com. I found this was the mailman2 behaviour on my old CentOS 7 installation and I am accustomed to it. I edited /opt/mailman/venv_mm/var/data/postfix_lmtp directly. Duplicated and edited all the lines. And compiled with postmap /opt/mailman/venv_mm/var/data/postfix_lmtp I sent a test email. This appears to work. Is this the best method to achieve this goal? What would you recommend?

Hi I can't seem to be able to add bans via mailman-shell: # mailman-wrapper shell Welcome to the GNU Mailman shell >>> from mailman.testing.documentation import dump_json >>> from mailman.interfaces.mailinglist import IMailingList >>> from zope.component import getUtility >>> list_manager = getUtility(IListManager) >>> mlist = list_manager.get('x2go-commits(a)lists.x2go.org') >>> bans = IBanManager(mlist) >>> new_bans = ["really", "long", "list", "with", "addresses", "I'd", "like", "to", "ban"] >>> for new_ban in new_bans: ... bans.ban(new_ban) ... >>> for ban in bans: ... print('{0}: {1}'.format(ban.list_id,ban.email)) ... [long list of bans] >>> exit() # mailman-wrapper shell Welcome to the GNU Mailman shell >>> from mailman.testing.documentation import dump_json >>> from mailman.interfaces.mailinglist import IMailingList >>> from zope.component import getUtility >>> list_manager = getUtility(IListManager) >>> mlist = list_manager.get('x2go-commits(a)lists.x2go.org') >>> bans = IBanManager(mlist) >>> for ban in bans: ... print('{0}: {1}'.format(ban.list_id,ban.email)) ... >>> exit() GNU Mailman 3.3.8 (Tom Sawyer), installed on Ubuntu 24.04 via distro packages (yes, they are completely broken; yes, I had to backport fixes from your Gitlab instance to even get this properly installed and working; yes, I think I can handle this) What could possibly be the cause of this? I don't even see any calls to the REST API for each bans.ban() call. Should I see those? Or is bans.ban() directly modifying the database? I skimmed the source code and it looks like as if IBanManager and the concrete BanManager model seem to work directly on a DB connection, so I assume that it's not going through REST. If that is the case (I'm using sqlite3, nothing fancy), why doesn't it stick? Do I have to commit changes somehow? Mihai

CSS Hyperkitty ERROR
by Johan Alsina April 12, 2025

April 12, 2025

Hi, i installed mailman3 with virtualenv, all is working fine, the admin site works fine, the mailman(postorious) site works fine, but when im in hyperkitty the site shows without the css style.. in my web browser dev tool it shows like they loaded ok.. Here you can see what i see when loading hyperkitty https://freeimage.host/i/3n6kXKQ and mailman(postorius) https://freeimage.host/i/mailman.3n6kVix When i run my server with verbosity it shows like all is loading ok: https://freeimage.host/i/3n6SViG Any ideas? :/ My static files are loading from /static/CACHE/css/output.a0f71925131b.css and /static/hyperkitty/libs/fonts/font-awesome/css/font-awesome.min.css It seems like the real error are in the /static/CACHE files, because hyperkitty is the only one who load files from this directory.. postorius uses /static/postorius and all the css files are working fine. I checked permissions for the directory, cleared cache, etc.. i dont know what to do. This is my config for staticfiles: STATIC_URL = 'static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), '/opt/mailman/projectes/mailman3web/static/CACHE', Thank you so much in advance.

Can't post to my own list from HyperKitty
by megabrutal＠gmail.com April 11, 2025

April 11, 2025

Hi Everyone, I've recently installed Mailman3 and still testing it. I tried to reply to a topic on my own list while also being a superuser from HyperKitty, but I got this error message: "This list is moderated, please subscribe to it before posting." Then why I even see the archive of the private list? What might be wrong? One thing that might confuse the system is that I added a secondary e-mail to my account. I thought it would allow me to post from any of my addresses, but it seems like it's not the case, looks like I can only subscribe with one of the addresses. It also looks like HyperKitty has trouble matching up the addresses, as it lists 4 participants for the conversation, while 2 of them is my account, the other 2 is my test address. In reality, it should list 2 posters. Best regards, MegaBrutal

Missing styling on select pages
by grodriguez＠usra.edu April 9, 2025

April 9, 2025

Hello all, I installed mailman3 on Rocky Linux 9 via the Virtualenv Installation installation guide. I configured Apache httpd to proxy gunicorn. For the most part, everything is looking good except for some select pages that do not contain the styling like all other pages. When a user sees the "Verify Your Email Address" screen, it's without any of the styling. /accounts/confirm-email/ Same for when a user tries to reset their password. The initial screen looks good (with styling), but after entering the email address and clicking "Reset My Password", the following screen is bare. /accounts/password/reset/done/ I have Mailman 3.3.10, Postorius Version 1.3.13, and HyperKitty version 1.3.12. Any suggestions?

Debian 12 postfix errors: "warning: connect to transport private/lmtp: Connection refused" and "status=deferred (mail transport unavailable)"
by Philip Bondi April 8, 2025

Hello to all: My apache2 issues are resolved. My xapian issues are not yet resolved, but this transport error is more important. I have de-configured lmtp within dovecot.

April 7, 2025

Hi team, Our Mailman3 server crashes with OOM and high CPU usage. As soon as we start the mailmanweb service (uwsgi process), the system crashes. It was working fine, but this issue started recently. We haven't changed any recently. Any idea how to fix this? or any suggestions? Look forward to hearing from you soon. Kind regards, Prasanth Nair

bypassing rules on an individual basis
by dlb-ml＠anl.gov April 4, 2025

April 4, 2025

I have a mailing list that, due to specific circumstances, has a requirement to allow messages from a user that sends messages with no subject. I've added the address to the "Accept these non-members" collection, but messages from that address still get held for moderation, due to the no-subect rule. https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rules/docs… https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rules/docs… I went through the list's interface, and I wasn't able to find a mechanism to disable the rule, aside from editing the code itself. I also added header filters to immediately accept the message, but they still get held. Specifically, the rules I defined are: Header, Pattern, Action subject, ^Subject:\s*([[{(]?no[_ ]subject[]})]?)?\s*$, Accept Immediately subject, ^Subject:, Accept Immediately subject, ^, Accept Immediately Did I configure this correctly and/or is this the right course of action? Is there a better way to bypass this rule? Thanks

Change delivery_status in bulk
by Hitashi mancho April 4, 2025

April 4, 2025

Dear All, We have a Mailman3 instance with around 500 mailing lists. Most of the mailing lists have 5000 subscribers. Because of some misconfiguration in the postfix, posting for 1000 users has been bounced. Until we realized what happened, the mailman had set delivery_status to "disabled_by_bounces." for many subscribers. Now, I am unable to locate any command or an API call through which I can change the delivery_status back to enabled for 1000+ users. Can you please guide me on how I can do this programmatically using cli (I will write a bash script) or using an API call? Regards, Hitachi.
