Correction:

They need to pull themselves out of the loop on this and allow DNS
to work as intended.

We are interested in feedback on the best way within the SMTP protocol
to definitively reject mail at these servers.

You need to:

 1) fatally reject mail for domains that are not delegated with 5xx

 -and-

 2) softly reject mail for domains that are delegated with 4xx so
    the messages are requeed and may get to an authorized server on
    the next run

Used to be able to use DNS for this.
