Another MS fix...

  - Strip <outbind://> tags out. This is a Microsoft only protocol and
    references files local to the sending machine.  This causes issues
    with Internet Explorer.
  - Replace <img src="outbind://"> links with clean images to stop
    issues with Internet Explorer not being able to track down the image.
