[Mimedefang] OT: Quoted text detection

[Amit Gupta]

In my mimedefang-filter, I'm trying to segment quoted text from an
original email  I realize this question is more to do with actual
email processing, but is there any trick within MD, MIME Tools or
another library that can help me out?  I realize there is no 100%
accurate way to do it. I'm just trying to get to 80%+.  There are just
a variety of different ways email clients mark quoted sections within
HTML and Text parts.
