              Every full fledged mail client supports filtering rules,
              as do many webmail clients.<br>
              <br>
              The In-Reply-To field was defined for email in RFC822 way
              way back in 1982, allowing mail clients to track a
              conversation across multiple replies, enabling threading,
              so you can view or ignore entire topics as a whole. &nbsp;This
              "next cool super tool" is built-in functionality, rather
              than the lack there of, and over 30 years old.

            <div>Raymond: &nbsp;I've seen&nbsp;a few replies, scattered out over
              several years, where you have made statements regarding
              certain mail clients and how they should honor the
              'In-Reply-To' field, but I never have seen a list of
              popular clients that do/don't honor this field. &nbsp;Can spout
              off a few for us? &nbsp;How do we tell if our client does this
              right or not?</div>

    Check the headers of your email when it gets bounced back from
    mailman.&nbsp; Thunderbird, Outlook, iOS mail, Squirrelmail, and
    RoundCubeMail all populate this (admittedly optional) header field.&nbsp;
    I've not actually found a client that doesn't, although I haven't
    been intentionally looking, and emails to the list that are lacking
    that field typically do not report a client.<br>
