In the /etc/hosts file leave the first line alone. On the line below that you'll put your internal ip address, your hostname and then server name. For example.
192.168.0.111 example.com SERVER
You don't need to run your own DNS server if your machine is specifying a DNS server to look at. Mine just looks at my router and then my router has a DNS server it looks at.
So yeah, add that line to the hosts file and make sure an MX is set up at DynDns. |
