Re: [ietf-smtp] SMTP Over TLS on Port 26 - Implicit TLS Proposal

There are people out there who has personal websites like and email address like me(_at_)firstnamelastname(_dot_)com

They are the only users of that domain and they probably need privacy. i.e.
If someone log the outgoing mails of, then the
privacy is being breached here. So those users don't want any traces.
Implicit TLS offers that.

To be clear, this is the problem with Opportunistic TLS.

A guy who sends an email to AshleyMadison support team probably cheating
his wife. He can protect the real conversation by upgrading the connection
to a secure connection with the help of STARTTLS. But the handshake before
the upgrade goes like this in plain text.

220 AshleyMadison ESMTP Service Ready

Ah, right, I misunderstood your use case.   However, who is it who needs
privacy here?   The end user is never going to connect to
