Paul,
PHI> The mail-ng transport protocol should be designed to only know about
PHI> a single hop, from sender to recipient. The sender may have multiple
PHI> hops to a designated transport agent, and the receiving transport
PHI> agent may have multiple hops to a mailstore, but the transport
PHI> protocol should not make any accommodation for these additional hops
PHI> other than to allow them to add metadata to the transit stream. These
PHI> requirements are to make the protocol more sensible and to limit the
PHI> responsibility of operators to just what they control.
How is this different from the current SMTP model?
