The MX Records of your domain are not pointed to Zoho.

The MX Records of your domain are not pointed to Zoho.

   Hello I have moved the emails for bebegiminlistesi.com and I have arranged the DNS records. I can see that the DNS changes are reflected by checking it at  http://mxtoolbox.com. On the other hand, I see the error " The MX Records of your domain are not pointed to Zoho. You may not receive emails in Zoho. ". I can receive some emails but some of them still go to previous mail host. I also cannot send email to this domain using Zoho. What can be the reason? Is it still about DNS delay?
