"It would be good to see the excellent work of Dukhovni and Parsons extended to include authentication of sending servers (clients) to support federation. " Why?

After <date>, we require them to use Secure X, Secure Y, and Secure Z, and traffic originated by the IETF sites shall use such protocols." Dear Fred, XMPP provides an interesting feature called server federation. It would be good to see the excellent work of Dukhovni and Parsons extended to include authentication of sending servers (clients) to support federation. This is something TLS supports but is rarely used. Such a feature could significantly improve overall security especially in the wake of RTF messages exposing users to remote code execution. DKIM only covers message fragments and is unrelated to the actual sender by design. A malicious link might be found in the Subject line that can be followed with user clicks which may not have been signed or users might see prepended From header fields which don't impact DKIM signature validity.
