Able to send out mail, but unable to receive.

Able to send out mail, but unable to receive.

I checked out my MX records in my domain settings and everything checks out. However, when I check with mxtoolbox.com nothing pops up.

I have link the account to my gmail account. I can use my OWN gmail account to send and receive mail to my email at zoho, but am unable to receive any other mails other than myself. I've ensured that my configuration in gmail are all correct as well.

Please help? Thanks!
