this is not quite right, the hosts file binds canonical names to an ip address, such that short names and fqdns can be added on the same line, eg:
192.168.1.1 host host.example.com
adding a domain name here would just create a mapping to the @ A record for the domain
assuming your nsswitch resolves file before dns (/etc/nsswitch.conf), and zimbra honours nsswitch resolv order you should be ok. |
