anyone have experience for setup Postfix Cluster ??? i think it is a good idea because it provide fault tolerance.
i am working on just that at the moment, trying both a cisco css 11500 load balancer and round robin dns load balancing. multiple postfix servers, connecting to a nas for centralised storage and mysql replication to keep all the databases the same for usernames and passwords, still in it's infancy stage though but work is being done on it daily!!
This will be very interesting Howto if this gets done. Hope this will materialized. But it has been more that a 2 years.
