You are pointing to email.  Some MTAs will use SMTP over TLS, but many others do not.  It would be great if they all do, especially for the authentication.  In your response you are talking about an email system that has been using plaintext for ages, and you are trying to apply hop-by-hop a mechanism to the delivery.  Then, you are saying that the sender and receiver have confidentiality expectations that are being violated.  I do not buy it.
