Actually, I wasn't proposing to use Auto-Submitted for autoforwarding.
I'd say that Auto-Submitted should be used iff the message sent is a
new message, with a new message-id etc. If the sieve script reinjects
the received message (same subject, same header fields generally, same
bodies) IMO the existing Received fields should be preserved and one
added.
