I'm dropping my hosting and email service with GoDaddy. I will maintain them as my registrar and DNS. I have setup an Ubuntu Linux 14.04.3 Apache2 web server and it is working. I just need to open the port and point my domain to my IP address. In addition I have another server running the same OS and Postfix/Dovecot.
My issue is with naming my email server and pointing the GoDaddy MX record to it. At this point the email server hostname is 'server' and the web server hostnamed is 'devrod.com'. I've read so much online I'm thoroughly confused. Will someone please guide me through the process of getting my MX record configured properly?
