As this was previously running I guess the Installation forum isn't the correct one, I'll move it for you. Did you search the forums for any similar problems and if so, what did you try to fix the problem?

Have you tried shutting down Zimbra (and killing any remaining processes, if there are any) and running zmfixperms (as root)?
Code:
/opt/zimbra/libexec/zmfixperms -extended

Well, for a start you hosts file is incorrect. Check the Quick Start Installation Guide for details of what you should have in there. Do you also have valid DNS A & MX records pointing to this server? Is it on the internet or is it behind a Firewall and/or a NAT router? I assume that the loopback IP address is a typing error?

You should put that information in your forum profile.
