I have a registered domain, call it xxx.com. I it is setup with nameserver ns1everydns.com ns2everydns.com My router is set to DNS 18.104.22.168 and 22.214.171.124 The Dell computer I am trying to set up Ubunto is named "mailserver". During installation I use mailserver.xxx.com I have searched google for detailed instructions to have a domain FQDN- can not find anything but bits and pieces. There is a thread here on how to do a domain registered with godaddy. Very detailed. I just might need a new domain and register it with godaddy. BUT, I sure would like to know how to do it with any other registrar. I am brand new and need help.
