2 Months have past since I am trying to configure email service without success.

First with Google Suite, some emails were not received. After 1 month I changed the service with zoho.

3 Weeks after, the same problem. We don't receive some mails. DKIM and SPF registers are not recognized by zoho. The domain provider tells me to change the NS to zoho ones. Is it possible?

Any suggestions?
