i have the similar questions on these two clauses: reject_unknown_reverse_client_hostname reject_unknown_client_hostname
I know the first one require the sender IP has a valid PTR. but for the second one, what's unknown client hostname? does it mean the PTR hostname must point to the sender IP as well?
