Forward mail to Zoho

Forward mail to Zoho

I have a domain mydomain.com, the domain hosting company (Binero) has free forwarding of mail for that domain without having to create a box at Binero. I am trying to forward that mail to my mail here at Zoho (it works forwarding to Gmail for example).

I keep getting the error:
<user@myzohodomain.com> (expanded from <user@mydomain>): user unknown
How does one fix this?
