I am having a little difficulty in understanding your email set up. Check whether the domain is present in /etc/localdomains.

There are so many reasons for this issue to happen. Same issue appeared to one of my client and I found that the domain was not in /etc/localdomains which the MX was pointing locally.

I added the domain name to /etc/localdomains and it has been worked
thanks for your support

This problem also happened to me on WHM 11.28.64 and the workaround provided above fixed the problem. Is this a cPanel bug?

Hello,

It is not a cPanel bug. If your domain has MX on the same server, it should be in /etc/localdomains. If the domain is having a remote MX, it should be placed in /etc/remotedomains.

Make sure that the e-mail routing setting for the domain is correct. In the WebHost Manager, click Main >> DNS Functions >> Edit DNS Zone and select the domain in question. At the bottom of the page will be a setting labeled "Email Routing for". Automatically Detect Configuration is the default, but you may need to select Local Mail Exchanger.
