DOMAIN_NOT_RESOLVED and MX

DOMAIN_NOT_RESOLVED and MX

Hi, 

When someone is trying to send emails to empower{at}alpashah.in it gives the error as  DOMAIN_NOT_RESOLVED

Few of the emails get through, also I keep getting the prompt that my mx is not configured correctly, it is created and visible when checked through a third party website.

Kindly take a look.

Thanks
