Problem with parsing email message with extraneous MIMEinformation

[Steven Allport]

Thanks for the response.

The section of the email is an actual message fragment. The first blank line 
that
appears in the message is immediately after the 1st

' boundary="------------m.182DA3C.BE6A21A3"'

There are no blank line prior to this in the message.

In the example that was snipped from an actual exported message there
is a set of 5 _NextPart_ lines followed by the message header for the 1st
attached message then a set of 7 _NextPart_ lines followed by the messge
header for the 2nd attached message. Comprising in total 6 set of _NextPart_
lines. As some of the attached messages also contained messages as
attachments.

Unfortunately it is not possible for me to post or leave the message 
anywhere
for you and so far I have been unable to recreate a test message of similar
format. I will endeavour to do so and will if I can will let you know where 
it
is.
