REFUGEES DO NOT RECEIVE EMAIL FROM THE WEBSITE WITH EMAIL SPECIFIC DOMAIN NAME

In the tutorial to create your own domain name email with Zoho Mail service, you see many of you are having a problem that if you send email directly to the address with the domain name is received, Use some form of contact on the website and set up email at your own domain to receive mail is not received.

It is weird because if you use cPanel as the host control panel (usually found in Shared Host services), the server will connect to the domain through the DNS records in the device. of cPanel, and will encounter if you use the intermediate DNS service because the server will not actually find the record for the email you have set up.
To fix this, visit cPanel -> MX Entry. Then add the MX records of your email service provider. That's it. Actually, I did not think about this cause, but just happened to configure a website on cPanel to find out, so I hope if you have the same situation will know where and why. fix it.
