I've asked the same question a few months ago and was looking at having multiple mail_replicas or using round robin DNS for the mail_replica. Here's how I "solved" it: Server A, B, C A -> B on A set mail_replica = B Mail arrives at A, syncs to B B -> C on B set mail_replica = C Mail arrives at B, syncs to C C -> A on C set mail_replica = A Mail arrives at C, syncs to A The more you add the higher the delays. Not the best solution but it works. Timo please add multiple mail_replicas and maybe priorities for high latency links. HTH B.
