And when the message turns out to be addressed to an alias or forward
which points outside that MX'es domain? Or the system that handles mail
spooling (final delivery) is not the same as the recipient MX (almost
always the case for corporates), and reponse time from the spool machine
may exceed an hour (seen this quite commonly during mail bursts)?
Consider AOL's case for starters. From what I can tell they have a
three-level setup, with a first line of simple receivers, a middle area
of message routers and analysers (eg where the silent discards happen),
and then a set of back end storage servers handling the LDA business.
