For the record Cyrus also [can] dedup messages via the Message-ID. 
Within the mail-store inbound messages with the same Message-ID are
stored as hard-linked files;  this can dramatically reduce storage &
I/O, particularly if your site has large distribution lists.

This can have some side-effects if you use mail in some very strange
ways [solution, IMO: don't do that].
