Do you need replication for load spreading or redundancy?
Both.
If the former, Cyrus IMAP is pretty good at spreading mailboxes across multiple servers while retaining a single IMAP namespace.
Perdition gives the same result and is a lot easier to manage.
If the latter then I recommend looking at DRBD, although of course that is limited to 2 node clusters unless you run iscsi on top of it...
DRBD has some big down-sides. It loses performance and it will reboot nodes if it thinks that there is a split-brain. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
