I can send email but I can't receive with zoho email.

Hello, 

I added my domain www.verydrone.com to zoho and I wanted to create different email such as contact@verydrone.com and support@verydrone.com

I can send email but I can't receive it. 

I checked the status on  http://mxtoolbox.com/ and it seems I have the god settings.

I dont understand, could you help me ? 

Regards.

Ben
