problems loading a mail message who is forwarded as attachment

Hello,

Indy 9.0.10.
If I open a rawMessage by IdMessage.LoadFromFile and save the textparts to
disk via SaveToFile I have a problem if the mail if forwarded as attachment.
In this case the body is ok but the second text part contains some header
lines. These header lines are from Date to Content-Disposition.
Whats wrong in this case? Outlook Displays the message correct.

Here the mail with the problem.
