I received a message that one of our smtp servers in our dmz may be an
open relay.

I have a plethora of IP addresses in the field
Allow messages only from the following internet hosts to be sent to
external internet domains:
Samples may be the IP addresses for multifunction devices used to scan
documents and email them to employees.

This scanning device is not in this list.

I know that using Configuration Documents has been deprecated for cipher
lists. Has Configuration documents also been deprecated for controlling
relay?
Is there some matching companion field that I need to have turned on also?
Like
Deny messages from the following internet hosts to be sent to external
internet domains:(* means all)
which is currently blank?
