Unable to recieve emails.

 Zoho says- the MX Records of your domain fairfield.lk are not pointed to Zoho and you may not receive emails in Zoho.

However my host shows the currently set mx record as mx.zoho.com

when i look it up on  http://mxtoolbox.com/, it shows as:

Sorry, we couldn't find any name servers for 'fairfield.lk'.


Please help
