Below is the announcement of a draft I just submitted that may be of
interest to this list. The approach here is complementary to the other
proposals I have seen along these lines (e.g., smtp-sts).

Thoughts, reviews, etc. welcomed.

A new version of I-D, draft-fenton-smtp-require-tls-00.txt
has been successfully submitted by Jim Fenton and posted to the
IETF repository.

Name:           draft-fenton-smtp-require-tls
Revision:       00
Title:          SMTP Require TLS Option
Document date:  2016-01-10
Group:          Individual Submission
Pages:          7

   The SMTP STARTTLS option, used in negotiating transport-level
   encryption of SMTP connections, is not as useful from a security
   standpoint as it might be because of its opportunistic nature;
   message delivery is prioritized over security.  This document
   describes a complementary option, REQUIRETLS, which causes message
   delivery to fail if a TLS connection with the required security
   characteristics cannot be negotiated with the next hop MTA or if that
   MTA does not also support REQUIRETLS.  Message originators may
   therefore expect transport security for messages sent with this


Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at
