I cant recive mails - MX problem

I have set up my MX mail server with appropiate values but Zoho continues without receiving emails and shows a message "The MX Records of your domain are not pointed to Zoho. You may not receive emails in Zoho. "
I had waited for 48 hour since I set the MX values in my sever.

Please how can I get my email work fine to recive emails.
Thanks in advance.
