Unable to receive emails

Unable to receive emails

I have made sure my MX records are correct. 

10 mx.zoho.com 165.254.167.50 120 sec Blacklist Check      SMTP Test
20 mx2.zoho.com 74.201.155.220 120 sec Blacklist Check      SMTP Test
30 mx3.zoho.com 74.201.155.79 5 min Blacklist Check      SMTP Test

Yet, I am not receiving emails, but I can still send them. I have looked through the forums, and was unable to find a solution for a person with the correct MX records.
