Mopher is a milter (or mail filter) and the original mail never
described it as being anything else than a milter (e.g. an MTA).

It was a rhetorical question since I wasn't sure what you were saying.

In that particular case, mopher doesn't need to do any lookups but uses
whatever libmilter provides as sender hostname (which, at least in case
of Postfix, should be a PTR RR that matches with the according A RR).
It then extracts the registered part with the help of the PSL rule-set.
The default greylisting is therefore based on the following triplet:
sender domain (the registered part), envelope from and recipient.
