OK. That sort of rewrite happens just at/after message acceptance :-
http://exim.org/exim-html-current/doc/html/spec_html/ch-how_exim_receives_and_delivers_mail.html#SECID14
The headers are available in the data ACL, which has the option of
denying acceptance - hence much be before that point. You could
copy a header into an acl variable there.
