I am so sorry to be reminded that I am the only person in the world who actually reads the fricking RFCs. Would everyone who's planning to continue this discussion please stop right now and read the relevant RFCs rather than guessing wrong? RFC 5321 section 4.4 describes the syntax of a Received header. RFC 8314 section 7.4 defines the "tls" and "group" clauses. To show that you read it, please include the first word in the text on page 50 or RFC 5321 in your reply. >Received: from mail.ietf.org (mail.ietf.org >[IPv6:2001:1900:3001:11:0:0:0:2c]) > by tncsrv06.tnetconsulting.net (8.15.2/8.15.2/Debian-3) with ESMTPS id >x0EJn9u3003563 > (version=TLSv1.2 cipher=ECDHE-RSA-AES256-GCM-SHA384 bits=256 verify=NO > ***Wouldn't*SNI*information*go*here?***) As anyone who has looked at RFC 5321 should know, that's a comment. You can put anything in a comment, but downstream code can't parse it reliably.
