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

Re: Postorius Suggestion: Give owner a view of all users of all owned lists

[Forgot reply to list] ---------- Forwarded Message ---------- Thank you Stephen for your questions. I have to admit that I thought about a quick and dirty solution, but you are right, it would not be optimal. Lets see: Stephen J.

Owners can manage subscriptions to the lists they > own. Agreed, "manage subscriptions" is what owners would need.

Owner is the primary target group for that. But since it should be a tool for managing subscriptions in a simple way, it might also be of interest for superusers. For me as a superuser it would make life easier. > Then you'd iterate over the logged-in owner's lists and collect all of > the subscriptions.

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". > Without a more complete specification of what your users need, and the > presentation they'd want to see, I personally am unwilling to go > farther than those comments. Maybe one of the other devs feels > differently. 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.b In our case Delivery Status and Delivery Mode are not interesting, but others might appreciate it. 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. 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? > Also, "domain owner" is way under-implemented currently. For the > hierarchical situation you outline, all the problems go away for > domain owners.

Yes, I agree, but policy here is to get rid of subdomains, and that falls on our feet now. -- Mit freundlichen Gruessen, Andreas Vetter

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!

Migration of the e-mail templates
by Markus Grandpré March 6, 2025

March 6, 2025

Dear list, When migrating the lists and archives from Mailman 2.1 to Mailman 3, the e-mail templates were obviously not migrated. Is there a way to make up for this?

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
