In article <CAOEezJQ0mJYvKW=SdbbE4ZC2Vx6_9FD5Z0SpkF2840r580vZ5w () mail gmail com> you write:
What IETF Mailing list thinks? - "Implicit TLS doesn't offer any additional security than a downgrade protected STARTTLS. Let's not waste a port."
He's forum shopping. He's already take this to two IETF lists and we've explained to him why it's not a good idea. If you want to say that all your mail servers use TLS, we already have DANE for people who can deal with DNSSEC and MTA-STS for people who can't (or don't want to for whatever reason.) We do not need yet another hack, particularly one which attempts to reserve string patterns in DNS names. R's, John
