One of our Cpanel server can’t restart EXIM on WHM giving the error
Waiting for exim to restart…. . . . . . . . . . . finished.
Service: [exim] has been disabled by the sys admin
This issue arises as the exim service is disabled in WHM>> Service Manager >> Exim.
So if you face the above error login to the WHM of the server and enable the service from the Service Manager. Now when you try to restart the service you should not face any error.
