In the single-server install manual, it is stated under RHEL customizations that
"Network Configuration>Network Devices>Hostname should be configured manually with the fully
qualified hostname [mailhost.example.com] of the Zimbra server"
Is this absolutely necessary, since I am going to be entering a domain when I do the install?
i.e.: I want to keep the name fred.thisplace.ext (not the real server name), and enter the actual "main" domain name during the install.
Does this work, or will I bork my install?
