DNS yes, but why SMTP? SMTP is not the problem. It is DNS that is
(possibly) a problem. DKIM already relies on DNS, so I see no reason why
ADSP should differ.
It would be utterly stupid if someone invented a naming space with the
same syntax as domain names but using something other than DNS, and then
let those names wander around freely on the internet. At the very least,
any such scheme MUST use some TLD(s) distinct from any that is approved
for DNS usage by ICANN.
