One way to fix this is as follows:
1. Login to your WHM as root and click on Exim Configuration Editor on your left.
2. Uncheck the box that says: Use callouts to verify the existence of email senders and Save.

4. Do a search for sender/callout.
5. When you find it, delete 'callout' and leave only 'sender'. Save.

AYK Solutions has been the server for my website for 8 or 9 years, and in all that time I have gotten nothing but expeditious, professional, friendly, and excellent service from them. I am being honest about this. They have my highest recommendations.
Best customer service I've encountered anywhere. Great product at a great price.
