Amongst the headers of messages from this list is one for unsubscribing that says sending mail to systemd-devel-requ...@lists.freedesktop.org with the subject of unsubscribe will do the trick. This does not work, and error message (550???) is returned saying the user systemd-devel-request was not found in the user tables. I tried twice.
Going to https://lists.freedesktop.org/mailman/listinfo/systemd-devel is says that subscribing is not available by email, only by the web interface. It would appear the same is so for unsubscribing. You may want to think about changing the unsubscibe headers you send out with every message to reflect the fact the mail to -request does not work. All the best, -- Znoteer znot...@mailbox.org
