I have three mailbox servers runnging SLES 10.1 and Zimbra 5.0.4. The servers are the following:
I have a virtual domain called mail and under the virtual host tab I have the three servers above listed.
In the DNS server I created the mail virtual host as A record pointing to all three of the mailbox server's IPs. I also install the proxy on all three mailbox servers. Is this the correct setup?
