Today's question: I would like to log the SNI in the Received header. Where should I put it?

Wouldn't it go in with the rest of the TLS information?

For example, here's the Received: header for the message that I'm replying to.

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?***)
        for <REDACTED>; Mon, 14 Jan 2019 13:49:11 -0600

I'd think that you would add the SNI information in the parentesis with the rest of the TLS information. As opposed to modifying the by line.
