Unable to receive emails in my Zoho email

Unable to receive emails in my Zoho email

Hi there, I am unable to receive email although I am able to send out. This is the reply I get when i send a test email to Zoho email from my gmail account.

Delivery to the following recipient failed permanently:


      info@agapehomeschool.org

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain  agapehomeschool.org  by  smtp.secureserver.net . [68.178.213.203].

The error that the other server returned was:
550 5.1.1 < info@agapehomeschool.org > Recipient not found.  < http://x.co/irbounce >

ALL MX records point to Zoho already, so we are not sure what the problem is.
Please respond

Please help.
Thanks, Mellisa
