Suddenly can't receive emails

Suddenly can't receive emails

Hello.

I have a problem since this morning, where I can't receive emails to my address: richard@stillorgancarpets.com

I can still send messages from that email address.

I sent a test message from another email account, and received back the following warning message:

    ----- The following addresses had fatal errors -----    
   [Status: DOMAIN_NOT_RESOLVED, Address: < richard@stillorgancarpets.com >, DOMAIN_NOT_RESOLVED]

...With the advice that the server will continue to attempt delivery.

Do I need to take any steps to fix this, or is it some kind of temporary error in Zoho's system which will be rectified shortly? I really need to be up and running again by tomorrow morning.

Thanks for any help!

Richard.
