Hi, I'm nobody :-) Our mail servers populate the BY clause like
BY servername (servicename [ipaddr])
The servers have different service personalities (e.g. MX vs submission)
depending on the IP address the client connects to. In Exim terms, the
ACLs vary per interface address, but the message routing after that point
is always the same.
Can you give some examples of "servicename"?
Are you suggesting that we add a new Received header field clause for
recording TLS SNI (instead of [ab]using BY)?
Thank you,
Alexey
