But I still want the future of email to adopt Implicit TLS. So someday we can kill Opportunistic TLS. I already lost the case for security. So my smtps part of the proposal not gonna fly. I'm just here to learn whether Implicit TLS can offer anything better than Opportunistic TLS that's worth wasting a port.
Well, the summary on the ietf-smtp list was that the new port doesn't actually buy you anything unless you have DANE, and once you have DANE, the new port doesn't add anything. The conclusion is that we should be deploying DANE more rather than burning a port. Not sure why you expect to hear much differently from NANOG.
