Problem to receive emails generated by a contact form of another domain.

Dear all,

I have been experiencing problem to receive emails from a contact form in a Wordpress Website. 

Basically, we have a website www.hydrogenhorizon.com. And we set Contact Form 7, a plugin to send a copy of the submitted forms to horizoneducational.com emails. However, we cannot receive it.

I already checked the MX fo www.hydrogenhorizon.com, and it is pointing to Zoho (mx2.zohomail.com, mx.zohomail.com).

I look forward to a solution to my problem.

Kind regards,

Matheus
