Enforcing SSO and subscription options
by dlb-ml＠anl.gov July 21, 2025

July 21, 2025

Contrary to the messages I found in the archive, rather trying to delete or remove the social login portion of the sign in page, I'm looking to see if there's any way to isolate the third-party login section and prevent local account sign in and sign up. This way, we can ensure that the people within our organization are using a stronger auth method that prioritizes MFA, rather than just username/password. To do this, our plan is to block signups using "ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter'" and to remove the portions of the login template such that the username/password/forgot password fields are removed, leaving just the button to our SSO instance. I'm anticipating that this should be sufficient to block username/password sign ins, and is resistant to page manipulation due to CSRF tokens, but I wanted to ask to see if there was a better way, like an official configuration (which I have not found yet). I did see that there is the SOCALACCOUNT_ONLY option, as provided by allauth (https://docs.allauth.org/en/latest/socialaccount/configuration.html) but that broke any attempt to display the sign in page, and I'm assuming is not supported with the current version of MM3. Is my plan to modify the templates viable? Additionally, because external users would not have access to their own dashboards within the web UI, and since we are planning on disabling anonymous subscriptions with "SHOW_ANONYMOUS_SUBSCRIBE_FORM=False", the only two viable ways to subscribe to a list for them would be: 1) Send a request directly to the list owner or a superadmin to subscribe/unsubscribe the address 2) Allow email commands to subcribe/unsubscribe users (i.e. $LISTNAME-join@$DOMAIN) Given the discussions on disabling the anonymous subscription form, are the email commands a less spam-susceptible solution or are they just as vulnerable as the form? Thanks

redirecting -bounces replies
by Hirayama, Pat June 26, 2025

June 26, 2025

Greetings, Is it possible to redirect the -bounces alias of a specific list so that it also goes to a person, in addition to the normal bounces processing for that list? In Mailman2, I know that I could do that by modifying the aliases table. I've been poking around in Mailman3, but haven't managed to figure out which container I need to be looking at. And rather than keep spinning, I figured that I'd ask the hive mind, since I'm sure one of you can quickly point me to the correct location. Thanks! -p Pat Hirayama Pronouns: he/him/his Systems Engineer IT | Systems Engineering - Infrastructure Fred Hutch Cancer Center O 206.667.4856 phirayam(a)fredhutch.org<mailto:phirayam@fredhutch.org>

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

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

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

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.

mailman3 on new Debian 12 installation, got ssl apache working on all URLs except /mailman3
by Philip Bondi April 1, 2025

April 1, 2025

Hello to all: Giant thank you to the community, Mark, Stephen, everyone. I have a lot of follow-up tasks in previous posts. Blazing forward on critical path flaws, first. I require a Debian 12 VM that supports: - Subversion - Let's Encrypt and required challenges - IMAP server - mailman3 - DKIM server I found this post helpful. https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… I think I've noticed that posters avoid less than sign and express as html. I hacked it into this, which I tried to anonymize. My alias /static/ had to point to different location for my installation. I have ssl working for Subversion and my Let's Encrypt challenges. And 6 of those ProxyPass seem to work through ssl, except for /mailman3. That fails. Surfing to example.com/mailman3 gets. Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. <IfModule mod_ssl.c> <VirtualHost *:80> ServerName example.com Redirect permanent / https://example.com/ DocumentRoot /var/www/html/example.com/ </VirtualHost> <VirtualHost *:443> SSLEngine on ServerAdmin pjbondi(a)systemdatabase.com ServerName example.com ServerAlias www.example.com DocumentRoot /var/www/html/example.com/ ErrorLog ${APACHE_LOG_DIR}/example.com_error.log CustomLog ${APACHE_LOG_DIR}/example.com_access.log combined Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/example.com-0001/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.com-0001/privkey.pem Alias /static/ /opt/mailman/web/static/ <Directory "/opt/mailman/web/static/"> Require all granted </Directory> <IfModule mod_headers.c> RequestHeader unset X-Forwarded-Proto <If "%{HTTPS} =~ /on/"> RequestHeader set X-Forwarded-Proto "https" </If> </IfModule> <IfModule mod_proxy.c> ProxyPreserveHost On ProxyPass "/postorius" "http://127.0.0.1:8000/postorius" ProxyPass "/hyperkitty" "http://127.0.0.1:8000/hyperkitty" ProxyPass "/accounts" "http://127.0.0.1:8000/accounts" ProxyPass "/admin" "http://127.0.0.1:8000/admin" ProxyPass "/user-profile" "http://127.0.0.1:8000/user-profile" ProxyPass "/mailman3" "http://127.0.0.1:8000/mailman3" ProxyPass "/archives" "http://127.0.0.1:8000/archives" # https://github.com/maxking/docker-mailman/issues/525 #ProxyPass / unix:/run/mailman3-web/uwsgi.sock|uwsgi://localhost/ #ProxyPassReverse / unix:/run/mailman3-web/uwsgi.sock|uwsgi://localhost/ #ProxyPassMatch "^/$" "http://127.0.0.1:8000/mailman3" </IfModule> </VirtualHost> </IfModule> I was noticing that there's no mailman3 sub-dir, here.

No emails distributed after mail received for a new list following https://docs.list.org/en/latest/install/virtualenv.html on new mailman3 Debian 12 installation
by Philip Bondi March 27, 2025

March 27, 2025

Hello to all: I require a Debian 12 VM that supports: - Subversion - Let's Encrypt and required challenges - IMAP server - mailman3 - DKIM server I'm currently running same on a CentOS 7.x VM. So that needs to be retired/migrated sooner rather than later because CentOS is out-of-support. On the Debian 12 VM other services appear to be setup and working. mailman3 is the 2nd last service that I'm standing up. In this moment, I've been able to follow https://docs.list.org/en/latest/install/virtualenv.html and https://docs.list.org/en/latest/config-web.html I have mailman3 and mailmanweb services running successfully. I have not yet been able to integrate mailmanweb into Apache (probably because of the Subversion and Let's Encrypt requirements). But I'm able to access local Postorius instance and configure a superuser and a list with web browser running locally on Debian 12 VM. My list is named ebill. An email was received for the DL, but not distributed. Can you advise how to troubleshoot from here?

remove website 'example.com' via django interface or "how to rush jourself off your feet" **Disclaimer: don't try this at home** in believe to replace the display of 'example.com' in the postorius-webinterface i logged into django-interface, under 'website' (very bottom of the left menu) i added my new website and then deleted 'example.com'. Result: i can't access my webinterfaces any more, neither django nor postorius. Questions: 1. Does somebody know about the correct approach to change the displayed url in the postorius-webinterface? 2. does somebody perhaps know how to revert those removal via CLI or other ways? greetings aiz

How to change the showed URL/Domain of archives navbar?
by Ulf R. March 18, 2025

March 18, 2025

Hello, our first Domain was lists-test.mydomain.de. After this we added our real domain lists.mydomain.de and our migration from mailman2.1 has finished :-) When you go to lists-test.mydomain.de/archives/ in the the navbar only the name of our first test-domain is shown (lists-test.mydomain.de). How can we set the other domain there? I have tried to change the order of our two domains in the settings.py - without success. Our domains are: lists-test.mydomain.de has SITE_ID = 1 lists.mydomain.de has SITE_ID = 2 Thank you and regards, Ulf

Postorius Suggestion: Give owner a view of all users of all owned lists
by Stephen J. Turnbull March 14, 2025

March 14, 2025

Andreas Vetter writes: > A list of all addresses subscribed to all lists owned by the logged > in person. This is starting to take a better form. It's still very specialized, so I'm starting to wonder if trying to add it to Postorius is a great idea. Of course if people are coming in over the network, you don't want to reproduce all the authentication and authorization logic implemented in Django and Postorius. That may as well be done in Django, and if you're doing Django it may as well be Postorius too. But if you're in a single sign-on environment so presence in the network implies strong authentication, you will get more flexibility from local scripts using mailmanclient, or if you're confident in security access to the REST API directly. Just putting that out for your consideration, since implementing what is taking shape here would take quite some time as the folks skilled with Postorius are not so active these days. > Owner is the primary target group for that.

[...] > Ah, I see the problem and agree: So, the presentation should have a > sorted and searchable list of addresses and a Button next to each > address, maybe labeled "Subscriptions". Looking at your description above, for superusers that is basically the Users tab, though. Users are identified by primary address, and you'd not see alternate addresses in the list. But presumably your internal users use their @your.org addresses as primary. Can you make clear what could be more streamlined for your use cases as superuser? I give one example below, maybe that's what you're mostly interested in. The caveats about access to User objects still apply for owners, so even if they look the same (which is a good UX idea if owner functionality is a subset of superuser functionality, also they might even be able to share the basic page templates), the implementation is going to be rather different. I suspect you superusers would be quite frustrated if using the "subscribe all these lists" functionality meant you couldn't get at the User object without going to a different page. I do see one weird thing: you can't manipulate subscription itself from the User page as seen by the superuser from that list, only toggle moderation and delivery mode. I guess that's reasonable for a lot of use cases, though. I've never wanted to do a subscribe or unsubscribe from there. I always have a long list of users to subscribe to specific lists, never a list of lists a specific user should belong to, > The presentation given when above "Subscriptions" Button is clicked > should contain the address as kind of Headline. Then a table of > all lists of the logged in owner and next to each mailing list an > indication, if the address is subscribed or not and a Button to > toggle subscription/unsubscription. May be a single Toggle Button > or (maybe better) two buttons, a suscribe and a unsubscribe button, > where one is greyed out. This would not work with the current User page as presented to a superuser, that's true. The current presentation is quite suited to its purpose, with sections for Addresses, Subscriptions, Ownership, and Delete User in that order. But especially for superusers, there are plenty of sites with thousands, even tens of thousands of lists, and even a paged or scrollable presentation would be awful UI, and the potential for a disastrous mistake using "do all" is high. > In addition my owners would like to have a "unsubscribe from all my > lists" button. And a "subscribe to all my lists" button. This might > be visually nicer, when having the two-button approach above. I wonder if your owners really want "subscribe all". "Unsubscribe all" does make sense for separations, of course, and they wouldn't necessarily be terminations. It would be useful in an internal transfer where "delete user" is not a solution. But in my experience specialized channels tend to proliferate but the same people are likely to be running them as run the department-wide lisst. > In our case we would want to (un-)subscribe the address in a "do > it, don't ask anyone" fashion, but maybe this is not a good idea in > general. What do you think? I think we would implement it similarly to the mass subscribe for multiple addresses case, where the list owner can decide how much bureaucracy to require of the subscriber. You'd want to be careful to make sure address verification is done at most once (for your use case, probably not at all). And there would be some things that could be done to arrange that most lists would have sensible defaults. > Yes, I agree, but policy here is to get rid of subdomains, and that > falls on our feet now. Well, once we figure out how to implement domain ownership, it wouldn't be hard to adapt that technology to "departments" that are administratively distinct but share mail and/or web domains. The main problem would be deciding whether and how to nest them. Superuser > domain owner > list owner > moderator is pretty obvious, but how "department owner" would fit in is less so.

Find a smtp server to send out emails
by Leon March 12, 2025

March 12, 2025

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman3. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. -- Best wishes, Leon

Help! Duplicate DKIM key
by Jose Bernal March 11, 2025

March 11, 2025

Hi all, I'm having *sudden* issues with our SMTP server (Amazon SES) erroring out while trying to send from our most active Mailman3 mailing list (~1,000 subscribers; modest Mailman3 (v 3.3.3) installation (10+ lists, Ubuntu). Here is the message. We've got several thousand log entries like this now: *554 Transaction failed: Duplicate header 'DKIM-Signature'* Mar 10 08:31:10 mail1 postfix/smtp[217753]: 738B53F15E: to=< brian(a)brianmichaelslaw.com>, relay=xxx.org[44.225.xxx.xx]:587, delay=37, delays=2/35/0.16/0.13, dsn=5.0.0, status=bounced (host said: 554 Transaction failed: Duplicate header 'DKIM-Signature'. (in reply to end of DATA command)) As we don't do any DKIM key signing on the related Postfix machine I've opened up a case with Amazon. However, if there is a troubleshooting I should adopt on this issue with regard to Postfix/Mailman I'd like to know what your recommendations are, or what steps I can follow to better help the vendor ensure that this issue isn't coming from either the Postfix machine or the Mailman machine. Much thanks, --------------------- José Bernal Web/Application Engineer

How to process emails with Mailman3?
by Kyle Lahnakoski March 11, 2025

March 11, 2025

Good day! I am setting up an email list for my local community (just myself right now). Being a nerd, I am using Amazon SES to send and receive emails. I have mailman installed on ec2 (using "pip install mailman") and it is working well enough to send an email to the list with /opt/mailman/venv/bin/mailman inject -f <somefile>all(a)mymaillist.org SES is putting incoming mail into an S3 bucket, one file per email. Using a small python program, I use the above command to send them to the list. When I add a user (like myself) I get a welcome email from all-request(a)mymaillist.org. When I respond, the mail arrives in the S3 bucket, but I do not know how to give it to mailman3. The "inject" command will not work because there is no "all-request" mailing list. How do I feed these administrative mails to mailman3? Thank you. ----- I have tried netcat the email to the ?LMTP? port, but it fails: (venv) [ec2-user@ip-10-0-3-253 mailman]$ nc localhost 8024 < /tmp/pbTw1oqmV1rZtHXV707Jcov264hr 220 ip-10-0-3-253.ec2.internal GNU Mailman LMTP runner 2.0 500 Error: command "RECEIVED-SPF:" not recognized 500 Error: command "AUTHENTICATION-RESULTS:" not recognized 500 Error: command "" not recognized 500 Error: command "" not recognized 502 5.5.1 Too many unrecognized commands, goodbye. here is what the first few lines of an email file look like.

Moderation of held emails vs. spam
by David Krantz March 11, 2025

March 11, 2025

Hi, I now run Mailman 3.3.1, installed from pip. Is there now any way to prevent Mailman from forwarding the contents of the held message when notifying moderators of held messages? In my case these messages often are spam messages and if the entire contents are forwarded it triggers spam handling in the recipient address(es) which over time risks classifying all moderation emails as spam or even classifying the list domain or server as a spam source. Even my own outgoing filter classifies it as spam, which I will fix. I currently run rspamd for spam filtering, graylisting and DKIM and ARC verification/signing. Someone on this recommended it, thank you for that as it removes the need for other milters. I guess that this would be a simple change to make as a kludge but a proper implementation as a setting would be a lot better. I'd like it as a global setting but that might be too coarse. Cheers // David

Postorius Suggestion: Give owner a view of all users of all owned lists
by Andreas Vetter March 10, 2025

March 10, 2025

Hi, it would be real great if owners that own several lists, but are not superusers, can see all users of all *their* lists and manage them. A down-"selected" version of the superusers view. Use case is an organisation (here are the superusers) with sub-organisations (here are the owners, e.g finance, research, production) having lists for the very sub-org itself and its sub-sub-orgs (e.g. research-all, research-solar, research-wind, research-battery). Would that be possible? -- Mit freundlichen Gruessen, Andreas Vetter

Bad Request 400 error with nginx/uwsgi install of venv
by zachr＠mta.ca March 10, 2025

March 10, 2025

Hello, and thanks in advance for any assistance. I followed the installation guide at: https://docs.mailman3.org/en/latest/install/virtualenv.html# I opted to use nginx and uwsgi. I can access mailman in the browser at https://SERVER_IP/mailman3 but when I try to use the hostname I get an nginx 400 bad request error. It seems like there is an issue with the nginx proxy. I used the example config and updated the required information: --------------------- server { listen 443 ssl default_server; listen [::]:443 ssl default_server; server_name HOSTNAME_OF_SERVER; location /static/ { alias /opt/mailman/web/static/; } location / { proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $remote_addr; } ssl_certificate /etc/pki/tls/certs/our_certificate.crt; ssl_certificate_key /etc/pki/tls/private/our_key.key; } --------------------- I thought maybe that because Im using uwsgi I should try the ngx_http_uwsgi_module and uwsgi_params in the nginx config, but that did not work, or I didnt use the correct syntax. Not sure what to try next!

Bug Report - REST API
by Peter Knowles March 6, 2025

March 6, 2025

OS: Debian 12 Mailman Core: 3.3.10 Install Method: venv When I apply the "count" and/or "page" param on: /3.1/lists/name.sub.domain.tld/requests This resulted in a "404 Not Found" error from the REST API. If I remove the params, the API returns results. From what I read in the docs, pagination should be possible on this type of endpoint as it returns "entries", "start" and "total_size". Tests against: /3.1/domains /3.1/lists Works fine with the "count" and "page" param as expected.

Hyperkitty Replies showing up as new posts
by Arte Chambers March 6, 2025

March 6, 2025

Hello, my Hyperkitty is creating a new post for each reply in a thread. I would expect that new posts to a list would show up in the archive and once you click on that thread you would see all replies. However in my Hyperkitty each reply to a thread shows up as its own post usually with the subject line saying RE: Original Message. How can I set up Hyperkitty to behave more like the lists.mailman3.org archives where replies to topics are filed under their respective threads? Thank you, Paul 'Arte Chambers' Robey 502-408-6922

Using clean_users.py
by Odhiambo Washington March 6, 2025

March 6, 2025

I have run clean_users.py with: DELETE_MAILMAN_USER = True DELETE_DJANGO_IF_MAILMAN = True However, when I go to https://mm3-site/mm/lists/listname.mm3-site/members/nonmember/ I still have hundreds of users listed despite the script having run and it showed hundreds of addresses removed. What might be the issue? I expect to NOT find anything listed as nonmembers. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 In an Internet failure case, the #1 suspect is a constant: DNS.

Set member.moderation_action via REST API as part of message approval?
by Andy Matthews March 5, 2025

March 5, 2025

We're using Mailman 3.3.9. My team and I have written a simple UI for displaying and approving/rejecting held messages from non list members. When an email receives an "always accept" flag from the UI we call the API to pass in the requested information: ``` Form form = new Form(); form.param("action", "accept"); Entity<Form> data = Entity.entity(form, MediaType.APPLICATION_FORM_URLENCODED_TYPE); String safePath = UriBuilder.fromPath("lists/{listId}/held/{messageId}").build(listId, messageId).toString(); response = getTarget().path(safePath).request().post(data); ``` If that request is successful we update the `accept_these_nonmembers` property of the mailing list with the user's email. ``` Form form = new Form(); if (fieldValue.getClass().isArray()) { for (String val : (String[])fieldValue) { form.param(property, String.valueOf(val)); } } else { form.param(property, String.valueOf(fieldValue)); } Entity<Form> data = Entity.entity(form, MediaType.APPLICATION_FORM_URLENCODED_TYPE); response = getTarget().path("lists/" + listId + "/config").request().method("PATCH", data); ``` The result of these two API calls is that both the subscribers and nonmembers properties of the mailing list are updated to include the new email (let's call it abc(a)123.com) The user can immediately send another email which is not held for moderation. The issue comes when a different nonmember sends an email and is approved (let's call it xyz(a)789.com) For some reason this blows out the "always accept" status of user abc(a)123.com and requires their email to be approved again. After some research I believe this is because the `accept_these_nonmembers` property has been deprecated (which seems valid because that property remains an empty array). Additional reading seems to indicate that we can now set `moderation_action` on each individual user which supercedes the mailing list's `default_nonmember_action` property (in our case it is `Action.hold`). The docs indicate that I should be able to submit a patch request to update the moderation action for any user: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/… But it requires the user ID. And when trying to get the user_id for a nonmember it appears that it is not returned by the API. The following call: `/3.0/addresses/abc(a)123.com` returns ``` { "email": "abc(a)123.com", "original_email": "abc(a)123.com", "registered_on": "2025-03-03T19:18:35.169703", "self_link": "https://0.0.0.0:8001/3.0/addresses/abc@123.com", "http_etag": "\"92c44d0b3b323450f3576e6352acb59b4cc5d6f0a\"" } ``` So I'm not sure how I would be able to update this particular record without a member or user id. So, all that said, I'm looking for information on how to do one of the following. 1. When submitting a user's email to the `accept_these_nonmembers`, is there a way to indicate that the `member.moderation_action` should be a specific value? 2. Retrieve a nonmember record and have it include a member or user id that I can use to explicitly update the `member.moderation_action` value? There may of course be additional approaches that I'm not considering, but that's about the gist of it. Thoughts?

How to follow up to a question on a Mailing List
by Odhiambo Washington March 4, 2025

March 4, 2025

Hello listers, I always find some members' posts to MM3 lists breaking threads to an extent no one can easily figure out what portion of the discussion they were responding to. In a way, they end up creating a loosely-attached thread of their own. I have a suggestion for you that can help improve this. Please refer to http://www.lemis.com/questions.html#answer/ The guide was written decades ago by a very respectable member of the FOSS community for freebsd-questions ML, but it's a guide that is pretty standard for every ML. Thank you for your understanding and consideration of the advice. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 In an Internet failure case, the #1 suspect is a constant: DNS.

Issues with a DMARC record leading to message being shunted

Something with DMARC and tags. So I checked the DMARC record for the sending domain somenet.org. It is "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;mailto:postmaster@somenet.org;ri=3600;fo=1;" which is syntactically incorrect. The extra ";mailto:postmaster@somenet.org" is wrong, I guess the tag "ruf=" is missing here! It should probably read "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;ruf=mailto:postmaster@somenet.org;ri=3600;fo=1;" So, should mm3 somehow "catch" this error somehow? According to the DMARC specs, an syntactically incorrect DMARC record should be ignored / handled as if none were present. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Archive download - unexpected end of file
by Mark March 2, 2025

March 2, 2025

Hi, I have a MM3 list to whose archive I recently added an mbox file of older emails. Viewing/searching the archive (Hyperkitty) is working fine. Downloading archives "for the month" or "last 30 days" delivers the expected ".mbox.gz" file and those are fine. However, when I download the "Entire archive" and attempt to gunzip that ".mbox.gz" file I get the error: " ... unexpected end of file". Or using Gnome desktop's "Extract", I get the error "..truncated gzip input" Any tips on resolving this would be gratefully received. Best, Mark

Hyperkitty django.request forbidden

Postorius extremely slow on some of the mailinglists
by Eric Broens March 1, 2025

March 1, 2025

Hi, Postorius became extremely slow recently on some of our mailinglists, but not on all of them. Postorius even times out when opening some of them (https://<hostname>/postorius/lists/<mailing_list>.<domain>/) and shows the message "Mailman REST API not available. Please start Mailman core." This only happens when I am logged in (as administrator), but not when I am not logged in. It seems to be independent on the number of subscribers on the particular mailing list. Below you'll find an extract from the logs for a case where it timed out, and for a case where the page showed up after a long time. Mainly "GET /3.1/lists/<mailing_list>@<domain>/requests HTTP/1.1" takes a long time. There is nothing unusual going on regarding database queries, and mails are delivered normally. Any idea why this happens and how it can be solved?
