remote server is misconfigured

Hi there, 

I recently set up domain connection email through ZOHO mail and I am not receiving emails from other email providers.I have tried to trouble shoot everything and I have all green checkmarks but nothing seems to still be working. The domain I am trying to connect is paitngo.org

The error message I am receiving from the Mail Delivery Subsystem through gmail is as follows.
