Not able to receive emails: MX suddenly not configured properly!

I just received this email:

Dear Admin,
Mail Domain hikemtshasta.com has been disabled by our MXLookup-Task
Reason : MX not configured properly
Implications : Mails may not be fetched in your users Zoho Account
Current MX Records : smtp.secureserver.net. [72.167.238.29, ] | mailstore1.secureserver.net. [72.167.238.201, ] |
Valid Zoho MX Records : mx.zohocorp.com[72.5.230.114, ] | mx2.zohocorp.com[72.5.230.119, ] | mx.zohomail.com[72.5.230.114, ] | mx2.zohomail.com[74.201.154.202, ] | mx3.zohomail.com[74.201.155.79, ] |

Now I can't receive any emails. I can send them but anything sent to my account is not delivered. I have tested this with a few different account and nothing is received.

There were no notifications or warnings of any updates or necessary modifications. I simply go the email out of the blue and things stopped working.

Thanks for any help!
