Were running ZCS 6.04 Open source for two years now on Ubuntu 8.04 guest in Win2k3 host (both 32bit). Its a single server install.
Our zimbra server uses a public IP and is also the single mx in our domain. I would like to setup two mx for failover in case one of the two ISP's were using suddenly cuts-off or a server fails.
I would like the two zcs server to have the same message content. That is either one of them is updating one another with the latest email received/delivered.
Is it possible? How can I do this? I'm not good at scripts but I can follow directions.
