I've just trapped one that has alot of similarities in the headers...but its
not exact:

Content-Type: multipart/related;

     boundary="====_ABC1234567890DEF_===="

Okay, quotes around that bit, and a slightly different boundary signature...

X-Content-Security: [mercury.motleypc.com] original Content-Type was
audio/x-wav;
Content-Type: application/octet-stream;
name="Sorry_about_yesterday.MP3.9061DEFANGED-pif"
Content-ID: <EA4DMGBP9p>
Content-Transfer-Encoding: base64

Content-ID looks the same. Two minor changes, then.

  In 1998 more than three times as many people in the US were killed
  by incompetent physicians than were killed by handguns, yet the
  President of the A.M.A. is adopting "gun safety" as his platform.
