Not to throw a damp towel on this discussion, but isn't this really an
administrative problem rather than a technical one? I.e. shouldn't the
system administrator set up a version control system or even something
like dropbox for file sharing rather than using email for this situation?

My users frequently mail documents to the person in the office next door
(never mind that both their home directories are on the same server!);
however this content is almost always different for each attached file;
i.e. without re-implementing a version control system under IMAP, as
you're suggesting, there would be little benefit in keeping and hard
linking to a single copy of each file. However, that seems like it
fails the UNIX "do one thing, and do it well" test pretty badly.
