Doesn't this mean that DMP [...] require a minimum of 2
DNS queries?
More like a maximum of two, minimum of one[1].
Ok, so DMP doesn't require you to fetch *both* the TXT record and the
A record? Doesn't the TXT just say that "yes, this domain uses DMP"?
There's no A RR used at all in DMP.
Ooops, I was confused with FSV. But, that doesn't change my point much.
So a receiver queries the IP+domain first, and if it gives NXDOMAIN only then
What is this "IP+domain" thing? That is two queries, right? One for
the _smtp-client.$FQDN and one for the $REV-ADDRESS....$FQDN.
