You'll not get good solutions if you hide part of the problem. Anyway, do you mean that the attachment is the complete original message, i.e. the attachment contains the original headers and body including all MIME parts? If so, it should be fairly easy to extract the original message with the aid of FOSS mail processing libraries. It would be pretty straight-forward to implement in Java with the JavaMail extension (and mstor if the messages must be read from mbox files).
