I do think STARTLS might have a role to play in antispam if
there were some scalable way to do the authorization.


The problem is advertising the fact you support STARTTLS in
the DNS.

it is not an authorization problem.

The SMTP clients and servers exchange that information during the EHLO session of the SMTP transaction. Why do you need to advertise that via DNS?

Leaving all of this aside, how will the use of TLS with SMTP help resolve the spam problem?
