DNS/NAMESERVERS Setup

[kilburn]

Do you have the server in your home, behind a NAT router?

If this is the case, then you have to use godaddy's DNS service (TotalDNS if I recall correctly). You can find it somewhere among all the mess that their panel has. Once open, create the following records:

Type: A Name: (empty) IP: your.public.ip.addr
Type: A Name: www IP: your.public.ip.addr
Type: A Name: mail IP: your.public.ip.addr
Type: CNAME Name: pop3 Value: mail
Type: CNAME Name: smtp Value: mail
Type: MX Priority: 10 Name: (empty) Value: mail

This should be enough to get you running (don't forget to click the "save" button and wait a few minutes).

If the server is NOT behind a NAT router (it's in a datacenter), you can actually use ispcp's DNS service. To do that, just go to the "nameservers" section and setup {ns1,ns2}.yourdomain.com as the nameservers, both pointing to your public address. Wait some time and that's it too.
