Dear Oleg,

Thanks for the examples - things are looking clearer.  However, in
version 3, on my system the subpart is still given a MIME-Version
header.  Is this not incorrect?

Also, according to the documentation "A MIME-Version: header will also
be added" to the MIMEMultipart class, even though it actually seems to
be added by the MIMEBase class, and therefore to all subclasses.

Best wishes,

Nicholas
