I am super confused on how this all ties in. Basically I'm confused what name needs to match where or if it does not
Lets say I have a Exchange email server with the domain @arrowhead.com
I name my Exchange server SantaClaus (FQDN is SantaClaus.arrowhead.com) IP address 192.168.0.20
The Public IP of the router is 10.0.0.20 which forwards port 25 192.168.0.20
Now I go to godaddy.com and configure DNS
I need to create MX record for that.
Can I use anything I want for the MX?
then when I create the A record does it need to match the mx record? Do I point the host to the Public IP
back at @arrowhead.com. Would I need to create a MX record on the DNS server
would that be Santaclaus.arrowhead.com or should that match the mx record on godaddy.
I get messed up because everyone uses, smtp, or mail, or exchange in their examples.
