If "rich text" formatted email is sent to the email 
gateway from outlook express, and the email also has 
attachments, the actual text of the message is dropped.

Outlook express does something like this:

Content-Type: multipart/mixed;
        Content-Type: multipart/alternative;
                Content-Type: text/plain;
                Content-Type: text/html;
        Content-Type: 4whatevers/attached;
