References: is for Usenet news, not email. Email uses In-Reply-To.
In fact, on my local server, mail messages from the centos list are
fed through a filter that changes In-Reply-To to References and then
fed into my local INN news server, so I can read it with a threaded
news reader instead of a mail program. The group is set to be moderated,
so when I post, it gets emailed to the list address. Before doing so,
it goes through another filter that changes the References: header
back to an In-Reply-To with the mode recent message-ID.
