What if we had something like an MX record published for the IP
address(es) in reverse DNS / <d>.<c>.<b>.<a>.in-addr.arpa for
<a>.<b>.<c>.<d> and configure those MX records to route to a mail server
of the owners / administrators of the IP (space) in question?
Do reverse DNS entries support the TXT structure? Why not just create a
special, specific TXT record for a contact email address?
This might be a good time to review the RP DNS record. See RFC 1183.
As far as I can tell, I am the only person in the world that still
publishes them.
I agree with this assessment.
