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 had never heard of AYK Solutions before, but they had an awesome deal I couldn't pass up on WHT. So far the service has been exceptional, and the server is rock solid. I'll be moving my other servers here soon!
Even though I only have a shared hosting plan, their technical support team responded to my tech support request within the hour, and correctly to boot. (I needed to have a subdomain point to a Tumblr blog by changing the CNAME.)
good service/support We have been with AYK for years. Good pricing/support. No complaints.
