Hello John, are you willing to share what direction you/IETF are working towards? What I am really missing is clear statements like SMTP-DANE, SPF, DKIM, DMARC are mandatory unless you don´t use SMTP at all. While some public providers support these, many German organizations do not. Just checked my own SMTP server implementation, it replies "214 Don't expect help". Thanks, Joachim

The current spec says that it is mandatory to implment it. Most MTAs implement it by returning a fixed string, or something close to fixed, e.g., gmail's answer appears to include a code that tells you which instance you're talking to. Unlike every other MTA I've looked at, Postfix doesn't implement it at alll and returns an error code. You don't have to tell me that it's not useful, but why not? It's in the spec, the work to return the string is trivial.
