cannot receive email

What's the MX record look like? If one exists, it is probably pointing to some other host. If one does not exist, that can be problematic [although you'd still receive mail].

Example: your mailserver IP is 1.2.3.4

You should have DNS records similar to these:

Code:

mail.yourdomain.com.    IN    A    1.2.3.4
yourdomain.com.         IN    MX   10 mail.yourdomain.com.

And, on the cPanel server where your mail is actually hosted, you should log into the /cpanel account, click on MX Entry, and make sure that the server is set as the Local Mail Exchanger.

Ok, on the remote server where the nameservice is being performed you have the MX record listed as mx.mydomain.com.

But do you have an A-record for mx.mydomain.com that resolves to the IP address of cPanel server that is handling mail?

If so, then at this point I think you need to contact the support staff for the server that is acting as your mailserver. You'll need to have them look in the logs to see what's going on. If you have root access to the cPanel server that is handling your mail, then you need to look at the mail logs -- /var/log/exim_mainlog, /var/log/exim_rejectlog, /var/log/exim_rejectlog and check and see what is happening with mail that is coming in for your domain.
