Actually, this is puzzling indeed–I notice there's no 'List-Unsubscribe' header in the messages that reach my Gmail inbox, but it _is_ present in the message that gets archived at e.g. https://inbox.ocaml.org/caml-list/CAH=h3gEOoMUBezUb3NoXvksX34ke3etP8=aScYeCzRc9p-ehrg@mail.gmail.com/raw

And in fact Gmail is not showing the 'unsubscribe' UI that it normally would if it found the 'List-Unsubscribe' header. Looks like something is stripping out the 'List-*' and perhaps other headers before delivering them to Gmail.

Perhaps this mailing list can be configured to automatically add (to each message) instructions for unsubscribing? I.e. go to https://sympa.inria.fr/sympa/signoff/caml-list , enter your email address, and click to unsubscribe.

This used to be the case, but such rewriting of messages was causing problems with DKIM and other email integrity checking scheme.

So, currently, we're just relying on subscribers to not be stupid and not send "unsubscribe" messages to the whole list.

The proper "List-Unsubscribe" header is added to every message, and a working e-mail client should take advantage of it to offer an "unsubscribe from this mailing-list" option.
