Orginal mail has the following Content-type
Content-type: text/html
Outlook and Outlook Express does not like the format below after been sanitized
Content-Type: multipart/mixed; boundary="=?iso-8859-1?B?I0RNLTE2ODMwNDkwNjIj?="
Outlook Express therefore do not show the body of the message, and outlook does not show the mail in this original html format.
