The Cyrus Murder provides the ability to horizontally scale your Cyrus IMAP environment across multiple servers. It is similar in nature to various proxy solutions such as nginx or perdition with the difference being that Murder offers a uniform namespace. Those not currently using shared mailboxes and who don't intend to use shared mailboxes in the future, should probably just consider using a simple proxy solution.
