Hi, We’re currently hosted by EMWD who upgraded the Mailman 2 cPanel/Python and have been unable to resolve the issues we’re experiencing. We would like to join a Mailman 3 list to see how it all looks and works. Do you have any recommendation? Best, Cathryn McGuire

Threads by month dropdown
by Sam Darwin June 7, 2025

June 7, 2025

Hi, After running hyperkitty_import to import thousands of emails from mailman2 (the years 2013-2025) I then ran another import for years 2004-2013 from another mbox file. It was an entirely earlier timeframe, which may be relevant. After the first import, the "Threads by month" dropdown showed 2013-2025. After the second import, the "Threads by month" dropdown showed 2013-2025. That is, 2004-2013 are missing. I have tried various things, including the mailman3-web cron maintenance tasks, waiting a day, and rebooting the server to clear memory. All messages were imported, and can be seen in "All threads". The messages are there. The only problem is the "Threads by month" dropdown. Beyond the dropdown, everything seems fine. Could it be a bug? Should I open an issue? Or, what should I try next? Is there a "refresh all threads by month" specific task? Deleting all archives and importing the older messages first... that worked correctly. It is a large destructive actions though, should that count as the official solution? Detour: While debugging it seemed to be an interesting question whether the mailman3-web periodic cron tasks had been running, and if those tasks affected the hyperkitty import. Referring to "Cron Jobs for Mailman Web" https://docs.mailman3.org/en/latest/install/virtualenv.html#cron-jobs-for-m… Those instructions are not dumping stdout/stderr to a log file, nor rotating the log files. What is your opinion if I sent a pull request that adds "Method 2 - Advanced", and include logging for the crons. Or maybe I am missing something. Is the output of the cron tasks getting logged in your environment?

What is the best practice creating lists triggered by a another / second system?
by Christian Schneider June 6, 2025

Dear MM-Users, after reading a lot in the projects documentation of mailman3 I am not sure how to set up a "connection" between another system/server (running a self-service portal for our users) and the mailman3 server (venv-installation) for creating lists (giving a list owner's email address and a customized list style, given by name). On our old mailman-2.1 instance I used an ssh-tunnel and triggered the newlist-command with appropriate parameters. This seems a little bit outdated to me - nowadays... ;-) So I read about the rest api of mailman3 and thought, I might give it a go... On the other hand the rest api should not be exposed externally (localhost-only) as said here: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… Running an nginx reverse proxy (and a firewall for the complete subnet) I am able to give dedicated access to the api but nevertheless I have no good feeling going this way... So my question is: What would be the best way to trigger creation of lists using a second system? Thank you for any suggestions! Chris

Recently active discussions - Hyperkitty
by Sam Darwin 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
