I have a virtual machine on Azure that is hosting a company product website.
We have a domain name (www.example123.com) at Godaddy.com with SSL certification bound to our virtual machine.
We are using Cynet Cpanel for email services, using mail.example123.com.
Problem
Godaddy: www.example123.com
Cynet: example123.com
1) When people search www.example123.com (godaddy) it is clashing with example123.com (cynet host)
2) How to make both domain names work?
i. Godaddy domain will point to Virtual Machine IIS webhost
ii. Godaddy will point only MX Record to Cynet mail.example123.com
3) How to avoid these DNS clashing into each other?
4) Can we permanently redirect example123.com (Cynet) to www.example123.com (Godaddy)?
