http://notmuchmail.org/ by Carl Worth and others is another candidate. It is based on the idea of indexing mails with Xapian, then doing all of the normal operations via tagging and fast searches.
Actually receiving and sending mail has to be handled separately. There's a command line and Emacs interface. It is clearly not something for normal users, but looks promising.
