Problem with parsing email message with extraneous MIME information

[sandipm]

I think I faced same problem quite sometime back...
but in our case, due to some settings in Microsoft outlook , forwarded
emails were  also coming as an attachment to email.

so That attachement itself has same format as email's format, so to
get information from attachment we needed to treat attachment as a
email to parse it.
can you send me some full email file? it will help to analyze
problem..
