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.

Regarding nested mailing lists in mailman 3
by Chandrakant Pandey April 2, 2025

April 2, 2025

Hi, I want to know whether we can setup nested mailing lists in mailman 3 which we used to do in mailman 2. like ep2021@iitb.ac.in,ep2022@iitb.ac.in,ep2023@iitb.ac.in mailing lists exist and we add all this mailing lists as member in ep(a)iitb.ac.in. Whether this kind of nested mailing lists work ? --chandrakant

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
by Alexander Inzinger-Zrock March 27, 2025

March 27, 2025

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

Hello, after switching from mailman2.1 to mailman3 mails with HCL Notes invitations are failing.

Is it a problem of the python code or the format of the HCL Notes Server? In the .eml file I see 25 header fields calles "X-Notes-Item". May be it is an overflow? Any ideas?

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.

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

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

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

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.

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
by Arpad Horvath March 1, 2025

March 1, 2025

Hi, I moved from mailman to mailman3 in 2021. I hadn't have the time to fix the archiving. I can see the emails older then that in Hyperkitty, but none of the once still there is mailman3. What can be the problem? It's a Debian 12, I use the packages from the repo. In the mailman-web.log I can see this: [pid: 861|app: 0|req: 8277/8277] xxx.xxx.xxx.xxx () {40 vars in 636 bytes} [Wed Feb 26 06:47:31 2025] GET /hyperkitty/api/mailman/urls?mlist=korus%40lists.somewhere.xx = > generated 221 bytes in 33 msecs (HTTP/1.1 403) 7 headers in 211 bytes (1 switches on core 1) ERROR 2025-02-26 06:47:31,705 861 hyperkitty.views.mailman Access to the archiving API endpoint was forbidden from IP xxx.xxx.xxx.xxx, your MAILMAN_ARCHIVER_FROM setting may be misconfigured WARNING 2025-02-26 06:47:31,705 861 django.request Forbidden: /hyperkitty/api/mailman/urls WARNING 2025-02-26 06:47:31,705 861 django.request Forbidden: /hyperkitty/api/mailman/urls I have this line in /etc/mailman3/mailman-web.py MAILMAN_ARCHIVER_FROM = ('https://lists.somewhere.xx/hyperkitty', '::1') I have the Archiving settings: Archive policy is Private archives At Active archivers hyperkitty's checkbox is checked Archive rendering mode is Plain text I have these packages installed right now: ii mailman3 3.3.8-2~deb12u2 ii mailman3-full 3.3.8-2~deb12u2 ii mailman3-web 0+20200530-2.1 ii python3-django-mailman3 1.3.9-1 ii python3-mailman-hyperkitty 1.2.1-1 ii python3-mailmanclient 3.3.5-1 Thanks, Árpád

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?

Postfix + MariaDB + Mailman 3 Core
by Peter Knowles Feb. 28, 2025

Feb. 28, 2025

== ENVIRONMENT == OS: Debian 12 Mailman Core: 3.11.2 Install Mode: venv == QUESTION == I'd like to do a more advanced setup with regards to my MTA setup. *** I have mastered the art of setting up Mailman 3 Core to use MariaDB vs PostgreSQL *** What I'm after is the ability to make use of MariaDB with: transport_maps local_recipient_maps relay_domains In particular, with regards to Mailman 3 Core generated content. So instead of referencing a postmap generated file which MM3 presently generates, but have MM3 add and/or remove those records to/from a MariaDB table. Appreciate any insights on this task.

Postorius custom web forms?
by Johannes Rohr Feb. 28, 2025

Feb. 28, 2025

Dear all, I am trying to understand how to replace a web template used by postorius by a custom version. I need to replace /accounts/signup by a version with a captcha (using django-simple-captcha) because my instance is being overrun by spambots. Can anyone point me to the correct instructions? I've tried to get instructions for chatgpt and co, but that's totally hopeless. Most of what they say is made up and doesn't work.. Cheers, thanks so much in advance, Johannes

Easy way to integrate captcha/reduce subscription spam?
by Johannes Rohr Feb. 25, 2025

Feb. 25, 2025

Dear all, my mailman3 instance is flooded with subscription spam, yet I haven't found any canonical method of integrating a captcha in to the subscription form. Is there really none at all? Perplexity.ai says I should install the python package django-simple-captcha but is unclear about the steps needed to actually make the captcha appear. Are there other ways? Is there any method that is robust and survives upgrades? Also, would there be a way of batch-deleting all those thousands of spam registrations that have accumulated (what they have in common is that their email is unconfirmed) Thanks in advance for any suggestion! Johannes

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? Thanks a lot in advance! Johannes

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

Feb. 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

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.
