Yep. That's how the hardlinks work. Users' quota would be updated
whenever the user himself unlinks the mail.

This could be problematic with filesystem quota though, since no user
actually owns the file so the quota isn't tracked for anyone (except
possibly for that dummy share user). That could even be abused by Ccing
a huge mail to yourself and some other user. No-one's quota gets
increased..
