pc1 does not retain any messages. Repeated readings of the same
message require repeated retrievals from srv1.
srv1 - MDA
messages - MS
pc1 - MUA
line between MTA and srv1 - SMTP
line between messages and pc1 - POP or IMAP or local access
This would make for an amazingly stupid POP client, a somewhat stupid
IMAP client, and a use of a local access client that would piss-off
some sys admins.
2. How do we model the components and downstream interactions of srv2 and pc2:

MTA

Messages are retained on pc1 and not on srv1.
srv1 - MDA
messages under srv1 - MS
pc1 - MUA
messages under pc1 - MUA's local cache of messages (same for
/bin/mail messages in ~/Mail, POP client's mailboxes, or IMAP
client's cached data)
line between MTA and srv1 - SMTP
line between messages and pc1 - POP or IMAP or local access
These two implementations/configurations are not architecturally different.
