I am not receiving emails from GMAIL or AOL.

Hi there, 

I recently set up Zoho Mail through domain connection. I have all green checkmarks saying everything is connected but there I am still not receiving those emails. The domain that I have tried to set up is grandeurmedia.co. 

The email that bounces back to gmail is as follows.
