Other forum software has a nice feature for this scenario: If I post to a subject, I am automatically subscribed to that subject. I then get an e-mail for any new posts with the same subject.
The "topic" feature in Mailman is different. Very few people use it. I need something based on the e-mail subject.
Is there any way to achieve that with Mailman?
Systers Mailman has a 'dlist' (dynamic sublists) feature which may be what you want. This is mentioned at <https://mail.python.org/pipermail/mailman-users/2010-August/070057.html>. That post is old and the repo at <https://launchpad.net/systers> mentioned therein is also old, but it still exists although the documentation links in the post and the README files in the repo are all broken.
We have been looking at dlists or something similar for Mailman 3, and Systers also has done Mailman 3 work (see <https://github.com/systers>).
You may be able to port the changes from <https://launchpad.net/systers> to more current Mailman, or perhaps contact Systers for more information. It appears they are still using a Mailman 2.1.12 version with their changes. I.e., see <http://systers.org/mailman/listinfo/>.
