Mail format transfer

Hello, when a MIME mail reach to the mail.box, The domino mail server has transferred the mail to a ‘note’ format document and store to the mail.box, Is there any API or method that we can tranfer this kind of ‘note’ format document to the original raw format MIME message(without any parse)?

Thanks in advance.
