if it's maildir at both sides, the simple thing is to copy the files
(cp, scp, rync, ... etc.)

if you believe smtp is the right transport, then:
- you'll need to make sure the "Delivered-To" header does not match the
next destination address (otherwise, Mr postfix will "think" this is a loop)
- get the MAIL FROM address from the "Return-Path" header. with this you
can do: sendmail -f $returnpath yourdestinationemail
