Mail Not Delivered to .ng domain

Mail Not Delivered to .ng domain

Hello,

I recently migrated my mail client to zoho. I am able to receive and send emails except for sending to .ng.

All mails sent to .ng are not delivered though I am able to receive from the same .ng.

Please help and advise on a solution as I would like to know if I should make plans to go back to GoDaddy.
