Capable opensource embeddable html email control

Question

Does an opensource web control exist that can read raw mime-encoded email (stored in a mysql db) and reliably render it to the browser? Something along the lines of fckeditor but email focussed?

The control only needs to be able to render the email (and preferably expose APIs for working with the email header, attachments and contents). We have no need to edit or send emails.

Thanks!
