It is improper to rewrite any field, except perhaps the "envelope". Just
pass the message as it is: if the originating MUA used proper domain
addresses, everything will work nicely; any other combination is bound to
fail anyhow.

The recipient fields in the envelope should only be rewritten if they
contain source routes: one should indeed remove references to the local site.
