These headers don't provide any useful information, can you please forward such a message (attached to another one) to my personal address which can be retrieved via clicking the Contact ... link in IERenderer's About ... dialog accessible via it's menu (click the rightmost button on Pegasus Mail's toolbar)? The most significant header with regard to contents is the Content-type header (if any) which will most probably look something like Content-type: multipart/something ...
