So I've downloaded the Open Source version of Zimbra and I'm rolling up my sleeves to start setting up. I've read the docs on setting up multiple servers and just this morning fired up a box with LDAP, logging and zimbra-store. In that process I note that it asks me for the name of my smtp host. Since it looks like I can only enter 1 server name here, how does that impact having multiple mta's? What would be the correct entry? Right now my plan for testing is to setup 3 servers that should be able to handle about 500 accounts. 1 server for ldap, zimbra-store, & zimbra-logger and 2 servers for zimbra-mta's.
