PowerMail

http://www.powerdns.com/powermail/
PowerMail is a redundant and distributed system for receiving,storing, and forwarding email. It is particularly well suited for installations that handle an extremely large amount of mailboxes and/or forwards. PowerMail uses a central database to store all information about mailboxes and email forwards that you host. Mailboxes do not need system accounts. There is no central storage point of failure. Mailboxes can span multiple machines or disks and individual messages can be present redundantly - on more storage nodes than one. This means that even if part of the storage subsystem fails, there is no downtime or loss of mail. Mail is delivered straight into mailboxes; there is no intermediate copying, which greatly improves incoming performance (typically the bottleneck for large scale email systems). A side benefit is that messages with many recipients are delivered only once. Identical copies are stored as 'hard links'.
