Distribute address book beetween 2 zimbra servers

[ded001]

Hi all,

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.

Best regards.

I'm really sorry but I have found what I need on the forum (Mail Routing Issues)...
Thank you.
