Which address is the recipient? The one in the To: header? What if you
received it because you were CC'd? What if there are Resent-* headers?

If you had "envelope_to_add" and return_path_add" on the relevant
delivery router when the mail was received, then I'd use formail(1) from
the procmail suite to process the mail folder, extracting each mail in
turn and passing it to an external command ("formail -s") and then have
the relevant command be a short script which extracts the "Envelope_to:"
header, splits on the '@', extracts "Return-Path:", and then invokes
Exim for testing.
