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.
3. Go back to the Editor and click the Advanced Editor button.
4. Do a search for sender/callout.
5. When you find it, delete 'callout' and leave only 'sender'. Save.
I have been with ayksolutions for around 5 years and have been thoroughly impressed with them. All support tickets are answered within minutes, regardless of the time of day. Prices are very reasonable, especially considering the support and services they provide. They are constantly doing crazy deals for servers as well. If you're looking for someone good and reliable to host with, from shared hosting to dedicated servers, I easily recommend ayksolutions.
I have never experienced a more professional and personal client-based service such as I am enjoying from AYKSolutions. This is no plotted statement either. I'm not a guru by no means, and they have been unbelievably superb in helping me promptly, professionally, courteously, and completely. Thank you Artyom & team.
Great prices and service! Truly is painless, professional and polite (That's their slogan).
