Subject: [ietf-clear] Getting CSV ready for prime time
.
One thing that became blindingly clear is that if we want people to take
CSV seriously, we need some hack to say that the rest of a domain doesn't
have any mail clients. That lets domains mark big swaths of their name
space as bad, which would be a significant reason for people to start
looking for CSV records even when there aren't a whole lot of them to
find.
I concur. It would be very useful (and popular) to blanket entire domains
with "not authorized to send". The administrative burden to set/maintain
millions of negative SRV records will inhibit (or prevent) significant
deployment of CSV.
While I am not happy with traversing down or up the DNS tree, it's better
than the alternative: (failure to deploy CSV).
