Postfix uses different processes for various pickups and
deliveries, so what you describe would have to be done by a
different MTA. If the smptd accepts the message, it is stored in
the queue, then later the lmtp client picks it up and hands it off

My guess is that you won't be able to do this with Sieve. I think
even with Sendmail (it's been a while for me) it's going to queue
the message before initiating the LMTP connection you describe.
