    Today after the latest cpanel update I was unable to send mail. I spent several hours on this and finally found the root cause.

    Appearently, when cpanel did the update the /etc/ file was deleted and not replaced with a new file.

    I simply copied /etc/ from another cpanel server and was able to send mail instantly. This might help you and might not but it was the solution that did it for me!
