I'm wondering how others have their multi-server installs setup and if they've run into any problems or wished they had done things differently from the start.
We've been testing with a single server for a few months without any issues. Now we're moving all of our test users over to a multi-server setup and then I'm going to start migrating everyone else over. We're using 4 total servers: two mailbox servers, one ldap, and one imap/pop proxy with an mta.
One thing in particular that I'm interested in is how others configured them to look like one server. What I'm trying right now is I have two A records of zimbra.domain.com pointing back to the two IP addresses of the hosts. There are also A records for the hostnames themselves. I've set the virtual host and zimbraPublicServiceHostnameup for our primary domain to zimbra.domain.com.
