One of the destinations fails and the report goes back to the sender not to the intermediary who is looking after the destination list. The same issue arises with mailing lists in that individual contributors learn of delivery failures whereas it is in really a matter for the list owner to deal with. the back-scatter issue relates to accepting email via a chain of intermediaries and being unable to generate a delivery failure report because of the risk of forgery... (so related, but a different balance of good and evil). However the risk of backscatter also means that you cannot accept email and change your mind thereafter as to whether it is acceptable. It is often the case that people would like to revisit past decisions to accept email or merely wish to avoid keeping links open for extended periods whilst decisions are made. Some people use greylisting for just this purpose -- which is wasteful of resources and can result in very extended delivery times... viz making greylisting unnecessary would be a good outcome for the WG - -- richard Richard Clayton Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
