DNS Error: 32985845 DNS type 'mx' - e-mails not delivered

Hello,

I have a domain polskabrasil.pl registered at OVH.com and tried to create e-mail via Zoho website. I managed to create the e-mail and every test message I have sent from new e-mail address ( agata@polskabrasil.pl) was successfully delivered so far.

The problem is that no messages are being delivered to the new e-mail. I keep recieving the following error message:  DNS Error: 32985845 DNS type 'mx' lookup of polskabrasil.com responded with code NXDOMAIN Domain name not found: polskabrasil.com

I am pretty sure I followed all of the Zoho's instructions and set the DNS information on OVH's website as advised (please see the attachment) . Could anyone advise what I did wrongly or what could be the solution?

Many thanks!
