I’ve a multipart mail, i parse it creating a Tmail object.  
In the body i have “—start—” “—end—” marks that indicates a part  
of  
the text to delete.  
If i read the email and then deliver it without touching the body, it  
sends  
the correct mail (html format, attachments and so on)  
If i do someting like:  
mail.body=mail.body[0,mail.index("—start—")]+mail.body[mail.body.index("—end—",mail.body.length]  
when i send that mail i lost every html format and multipart data.

How modify the body without loosing the rest?
