One-click unsubscribe?
by Jered Floyd Dec. 6, 2025

Dec. 6, 2025

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

Internal Server Error: /mailman3/accounts/fedora/login/
by Alain D D Williams Nov. 20, 2025

Nov. 20, 2025

Twice today I have received many (50+) emails like the one below. Many at about 1pm, then it stopped now I am getting them again. An Internet search does not bring up anything useful. The domain at the start of 'Request URL' varies as does the name of the list (in this example 'announce(a)leavesden.org') The domain of the list is not necessarily the same as the domain at the start of the URL. I can receive several in a minute. Anyone any idea ? ----- Forwarded message from root(a)bf2024.phcomp.co.uk ----- Date: Mon, 02 Dec 2024 22:19:12 -0000 From: root(a)bf2024.phcomp.co.uk To: root@localhost Subject: [Django] ERROR

Block members from sending cc's and bcc's
by Cathryn McGuire Nov. 15, 2025

Nov. 15, 2025

Hi everyone, Using Mailman 3 with Affinity web interface and we want to stop our members from sending to cc: or bcc: We've found the Header Filter and cc and bcc appear in it. Tried to configure it to "hold for moderation," but it hasn't worked. Partly because we don't understand what to put in the Pattern input box. I put in cc: because it requires something. Can anyone advise? Cheers, Cathryn

Xapian alternatives

Nov. 11, 2025

Are there alternative search engines to Xapian that can be used for Mailman 3? I have come to understand that Xapian development stalled in the v2.0 attempt.

Sendgrid experiences
by Andrew Hodgson Oct. 6, 2025

Oct. 6, 2025

Hi. I am temporarily using Sendgrid now on my Mailman instance. Initial observations have been positive. A list with 100 users is racking up email delivers though, I am on the basic paid account which gives me 50k emails per month. I was hoping to use a cheaper provider and pay overage costs per email on the assumption that I'm seeing a spike in traffic today because people have started getting the messages again. Sendgrid is maintaining the Message-Id header which is good for archiving. It is re-writing the Return-Path header though which means that bounce handling in Mailman won't work, but I think all the services do this in some way so I am happy to live with that for the moment. Hope this helps. Andrew.

Login confusion
by Markus Grandpré Oct. 2, 2025

Oct. 2, 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

The MAILMAN_ARCHIVER_KEY was not sent as the Authorization HTTP header.
by Marco Marinello Sept. 23, 2025

Sept. 23, 2025

Hi everybody, as per subject, I'm getting this error in the hyperkitty log when mailman daemon tries to archive a mail. I've setup the hyperkitty.cfg file with api_key = MAILMAN_ARCHIVER_KEY in settings_local.py but still nothing. I've seen here and in GitLab issues some errors concerning a wrong api key but here it says that it wasn't sent at all. All packages installed via pip install + latest .zip release, including mailman-hyperkitty. Currently running on apache with mod_wsgi_py3 without https. Any clue? All the best, Marco Marinello

HSTS Missing from HTTPS Server
by jkoral＠luc.edu Sept. 17, 2025

Sept. 17, 2025

In my configuration, I am using Apache to reverse proxy the requests to a uwsgi. After our security office scanned the server, it was shown that HSTS is missing from the HTTPS server. The instructions say to add some lines to /etc/apache2/sites-enabled/. The only file in there is 000-default.conf that holds the configuration, but the VirtualHost is port 80. I am using an F5 to to automatically redirect port 80 to port 443, but it is still showing this vulnerability. My question is, how can enable the Virtual Host for 443 on the server? Or can that configuration be located somewhere else? Or can I just create a new Virtual Host with the added configuration for mailman? Thanks, Joe Koral

(venv) [mailman@gw ~/mm]$ Should I take it that the import was successful, or what should I do next? PS: This is the 1st run after installing MM3 on this server and the MM3 list hasn't gone live. So if anything, I am okay with doing what needs to be done and rerun the import.
