That was my guess. So you need a custom persistence manager and methods
to break down, store, reassemble a MimeMessage, manage UIDs and perform
the requests from the IMAP server.
That's not so far away from a completely custom, optimized
implementation. 

Okay, okay, I'm already convinced that having a backend implementation
that stores the mails into jackrabbit could be a desirable goal. :-)
