CAN SEND EMAIL BUT I CANT RECEIVE EMAIL

Hi Support,

Kindly help. I can send email but I can't receive emails. 

Upon sending email, I receive feedback in this format:

"Address not found
Your message wasn't delivered to  (email) because the address couldn't be found or is unable to receive email."

I sent an email to (support@zohomail.com) but no response was sent.
