I've been watching this thread with interest. Assume I have a domain with DNSSEC and inbound mail servers behind a (load-balanced) MX which support TLS.
If I've been following along correctly, if I publish a DNS record of the form: _25._tcp.*mx.mydomain.org <http://mx.mydomain.org>*. IN TLSA 3 1 1 *<sha2-256 digest of DER leaf public key in X.509 SPKI format>* this will make some (currently smallish?) set of mail servers sending to me have a better assurance they are really talking to me. Is this correct? And does "*leaf public key" *refer to the public key associated with the cert used for STARTTLS or ...something else...?
