Cannot receive email

Cannot receive email

Hello, I can send emails from my account fperalta@translingual.es, BUT I can NOT receive emails from other emails.
I've configured MX in my hosting, also I've cheked it with mxtools and it appears to be fine. DKIM is validated. But I still have the problem, I CAN NOT receive emails.

Please, may you help with this issue.
