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.
Dedicated Semi-Managed Server Review I've been using AYKSolutions for about 2 years now and their support and servers have been great. They assisted me with the transition of all my websites and databases from my old server onto their system with no problem. If I ever need them for support or a change they respond fast and always keep me up to date with the status of my support ticket. I highly recommend using this company especially if you're looking for someone to assist with server management. Best of all their cost is great!
Great host, have tried many they're certainly a top choice for me. Premium bandwidth, great prices, 100% stable, and great support.
