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've been a client of AYK Solutions for about six months now. They have provided the best overall experience I have had in over 10 years. I've tried iWeb, SingleHop, and a few others supposed to be the so-called best. Specifically, you are dealing with personal, professionals with AYK Solutions, and they are willing to help when all others want to charge you $** for this and $**/hr for that. I'm happy, and have no plans of going anywhere else; ever.
I recently switched to AYK Solutions from Softlayer for my dedicated server requirements. I received a much better specification server at significantly reduced cost from what Softlayer could offer me, with many of the previously 'extra' features at Softlayer included in the base price offered by AYK. The support was second to none, and they were extremely helpful in transferring all of my old server accounts over for no additional fee whatsoever.
