For performance reasons I need to deploy 2 zimbras server on 2 different sites for the same mail domain name, so I need to distribute the address book accordingly.
So How can I route messages between both servers to deliver mails correctly?
Do I need to create 2 virtual domain names and map each real email address accordingly?
Can I tell Zimbra to route unresolved email address to a "master" smtp server (even for the mail domain name zimbra serves)?
Thanks for your help.
