HALP! New user don't understand!

Hello! I'm new to this whole self-hosting stuff and am very confused with the mailserver. Will the domain auto manage the MX nameserver or will I have to program one? If I need to create an MX nameserver what do I need to do? 

Thanks!

You say "MX nameserver ". There is no such in DNS we create an MX DNS ENTRY pointing to a A Record that will point to server IP.

Let's say server ip: 1.1.1.1 and domain : google.Com

you should create an MX @ ( mean google.com MX entry) pointing to : mail.google.com
then add an A Entry mail.google.com that would point to 1.1.1.1

All zpanel tutorials mostly apply to sentora and we did not change so much the process. If you check you will see that.

You must understand what an MX entry and every kind of DNS.dns. This why I pointed you should learn more over DNS.

Adding records is easy thru interface and defaults are already there to help you.
