Postfix, with "smtpd_tls_received_header = yes", decorates the Received
header with TLS protocol information:
Received: from sbh17.songbird.com (sbh17.songbird.com [72.52.113.17])
(using TLSv1.1 with cipher DHE-RSA-AES256-SHA (256/256 bits))
by amnesiac.example.com (Postfix) with ESMTPS id 0609B2AA9FF
...
Is something like this supported by Exim? Are you specifically
looking for a separate header? Or would decorating the top-most
Received header (prepended by the receiving MTA) in a similar manner
be enough?
