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.
