would you try the OpenDedup File System? (http://www.opendedup.org) If your problem is (only) the message size, this will works like a charm to you.
Well, for me it's not a matter of size (I use FreeBSD ZFS which can do dedup by the way), but simply same message showing up on same inbox for twice, for IMAP, this can be quite annoying.
Also I don't think filesystem level dedup would work well for mail servers even using a filesystem that is capable for doing dedup (not to mention it's sometimes slow), because we store the message header together with the bodies, and they are likely to differ slightly (someone@ vs someoneelse@domainname), causing an offset in the message and thus make block-level dedup useless, so in order to efficiently use dedup (for speed and space), one have to migrate to a new storage format.
I'll take a look at the code and see if I can do that myself when I have some spare time, and thanks for everyone who replied.
Cheers,
