I said "realm" not "host." From the list to all of our in-boxes, the
envelope return address was politely changed to
"asrg-bounces at irtf.org" by Mailman version 2.1.9.

Figure 1 in rfc821 is the SMTP model, and it does not involve
intermediate hops.  Complex multi-host systems one one side or the
other collapse into "Sender SMTP" and "Receiver SMTP" in that diagram.

gmail realm <-> irtf realm <-> nortel realm

Two transmissions between realms.

I meant "realm" not "host" which is what I said.  If there's a better
term for what I mean by "realm" I am open to changing my terminology.

In arguing to drop store-and-forward as a requirement, the internal of
operations of a realm are considered a black box outside the FUSSP's
scope.
