Oh yes, quite a few: * Do it on delivery (by configuring your MTA to deliver to two places at once) * Use a tool like imapsync to replicate the mailboxes using IMAP periodically * Use filesystem-level replication (e.g. rsync/unison, ZFS mirroring) * Use block-level replication (e.g. drbd, Netapp snap-mirror) Which you use will depend partly on what the replica is being used for, e.g. just for archive/audit; how quickly it has to be in sync; what happens when the remote replica is unreachable; and whether you want to be able to failover to the replica for 'live' use, and fail back again.
