When you create your mailbox you need to provide a factory function, 
otherwise you get rfc822.Message objects.

It's not obvious to me what that facory should be: I'm guessing you 
could get away with something like

mymailbox = mailbox.UnixMailbox(fp, email.parser.Parser().parse)

but I am far from convinced that will work, and have no time for testing 
right now.
