This part is wrong.  The boundary line "--====-=-=" needs to be moved
after the rfc822 headers, like this:

 --=-=-=
 Content-Type: message/rfc822
 Content-Disposition: inline

 Content-Disposition: inline
 MIME-Version: 1.0
 Content-Type: multipart/mixed; boundary="====-=-="


 --====-=-=
 Foo

 --====-=-=--

Andreas.
