Implementing such changes in hypermail would probably not be too difficult, although scanning the body for message-ids could reduce performance.

The real problem with this proposal is to get users to include message-ids. My guess is that it just won't be possible to force users to not forget to do that.

The In-Reply-To header is already included in the URI behind the 'Respond' link on the html version of the page, at least in the setup for W3C lists (lists.w3.org). The question may be whether this header is included by the mail software then the user clicks on that link. The answer may differ for different mailers.

Regards, Martin.
