Actually, no it could not. The protocol spoken by the pipe(8) daemon is
the internal queue-manager <-> delivery-agent protocol. The pipe(8) daemon
is is a delivery agent, not an SMTP proxy. I think you are confusing pipe(8)
with spawn(8).

You *can* use spawn(8), but the proxy will be respawned for each
connection. Persistent daemons are more efficient.
