Message-ID perhaps? :-)

That may still leave identical messages not hard-linked thus wasting space.
Eg. if they come from MTA's that do recipient splitting, or messages that
are routed via different systems. The Received headers will be different
but the body generally identical.
I think a better solution is what was suggested here before, ie. to keep
the (unique) message headers in a Maildir-like format, containing links to
(single-instance stored) message bodies in a a separate location.
