The sentence is a bit > ambiguous. Are you really saying any host that sends mail (is an SMTP > client) MUST also host an listed SMTP server? I can't testify to what he meant, but I think what he is actually saying is that if you have a machine that says "EHLO some.name" then there should be both a MX record for some.name and a SRV record for _client._smtp.some.name (i.e. a CSV/CSA record). That doesn't mean requiring inbound SMTP on every outbound, it means requiring an affirmation in DNS that a name can be used in EHLO by a particular IP address and a way to get mail to the responsible party for the machine(s) using that name in EHLO. This is an admirable goal. A weaker goal would be to get people running non-spamming mail servers to follow the existing accepted standard of using a valid resolvable FQDN in EHLO.
