I'd need to see a sample message -- original message text, as seen by the app itself.
Fairly easy to do:
- If you use Outlook of Thunderbird, then do "Forward as attachment" (.eml). My address is kmansoft / gmail
OR
- Use web mail, and look for "View Original Message" or similar (in Gmail / web, it's next to the reply icon). Save to a plain text file (no Microsoft Word / WordPad / Apple Works etc). Send as an attachment.
