Yes, *if* milter-ns runs first.  See
http://www.sendmail.org/doc/sendmail-current/libmilter/docs/smfi_addheader.html

"For smfi_addheader, filter order is important. Later filters will see
 the header changes made by earlier ones."

(Note that there's really no need to use milter-ns.  You can do the same
thing in Perl with Net::DNS directly in your MIMEDefang filter.)
