domain that I recently got with email accounts that is configured in CPanel. The problem is when I send an email from my  email@mycurrentdomain.com to  email@mycurrentdomain.in id, it bounces saying 

email@mycurrentdomain.in Invalid Address, ERROR_CODE :550, ERROR_CODE :Verification failed for <email@mycurrentdomain.com> 
            No Such User Here 
            Sender verify failed 

Also the reverse sending (from .in to .com) fails saying no such account on .com!!!

However, I am able to send emails from any other domains like gmail/yahoo etc. to my .in account. Can you help me?
