You need to do the DKIM signing in filter_wrapup, a filter callback function
introduced in MIMEDefang version 2.76.  It gets passed the final MIME::Entity
with all your modifications.  You need to write this out to a temporary file
and use that file (not INPUTMSG) as the input for DKIM signing.
Use $entity->stringify() to get the message that you need to sign.
