Would not "sendmail -G" suppress local modification?
-G Gateway (relay) submission, as opposed to initial user submis-
sion. Either do not rewrite addresses at all, or update incom-
plete addresses with the domain information specified with
remote_header_rewrite_domain.
This is the recommended setting for post-filter re-injection. With
this, Postfix pretends that the mail is from a remote origin.
