Hello. Is it somehow possible to improve the interaction in between addressverification on the local, and greylisting on the remote side? I have very good experience with "AV" except for certain "AV"<->"AV" well "locks" that i have seen once or twice but of which i have forgotten anything, and its interaction with greylisting.
Actually, i do not truly understand why, in the below, things are finished. It seems to me the other side gets no sign that should make it think that there is no way to not succeed at a later time? Yet, it does not (well, *that* could, but i know it will not, i have seen this pattern in the past from that host, yet with another domain name). Only to be very clear about it for myself -- postfix does not indicate a permanent error in the below? It gives 450 (4.1.7 RFC 3463). *Could* it make any sense to "pass through" a 451 condition instead if address verification gets such a response? For now all i (think i) can do i whitelisting also this domain.
