CentOS 6.4, clean install. Zimbra 8.0.3 I am behind a PfSense box using a virtual IP. So the IP of the box is 192.168.1.27 I entered this in /etc/hosts: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.27 mail mail.meowbox.me meowbox.me but `hostname -f` says: $ hostname -f hostname: Unknown host Do I need to put the public IP for where this record resolves? Since PFSense is forwarding traffic from it to the virtual IP? Jason
