cPanel email-can't send from other mail server but can send email?!?

[trungstormsix]

Hello,

I created some email on cpanel of domain ocodereducation.com ex jeff@ocodereducation.com

In the past, I can sent and received the email.

But NOW, I CANT NOT receive email send from other mail server (Ex: gmail) but I can sent email to out side (Ex: send mail to Gmail is ok)

Could you please help me this problem?

Thanks!

Hi @trungstormsix,

Welcome to the Community!

An external lookup of you DNS indicates that you may be missing one or more required records for the cPanel email to function. Check to see that all the required records are in place. 

A Record: host= @  Points to= Your account's IP address
A Record: host= mail  Points to= Your account's IP address
CNAME: host= www  Points to= @
MX: host= @   Points to= mail.[your domain name]
