I'd need the exact full source code of such "bad" message -- mail headers and content, the whole thing.
You can obtain it in a desktop mail app, in web mail, look for "show original", "view message source" etc.
If you can get this, please save to a plain text file (not Word) and email as attachment to kmansoft / gmail.
Or you can forward the message as an ".eml" attachment in Outlook.
