You can also just customize the Received: header to include that info.
I've been trying:
-------
received_header_text = Received: \
${if def:sender_rcvhost {from $sender_rcvhost\n\t}\
{${if def:sender_ident {from $sender_ident }}\
${if def:sender_helo_name {(helo=$sender_helo_name)\n\t}}}}\
by $primary_hostname \
${if def:received_protocol {with $received_protocol}} \
${if def:authenticated_id {(userid:$authenticated_id)}}\
${if def:tls_cipher {($tls_cipher)\n\t}}\
(Exim $version_number)\n\t\
id $message_id\
${if def:received_for {\n\tfor $received_for}}
---------
So you end up having something like
.... with asmtp (userid:barryp)(TLSv1:RC4-SHA:128) ....
included in that header entry.
