Hello 
Are you attempting to limit email access globally for the entire server or limit access to a single account?
Thank you.

The following options might be of help to you if you want to block access for all IP addresses except for your own:
"WHM Home » Security Center » Host Access Control"
"WHM Home » Security Center » cPHulk Brute Force Protection"
Thank you.

Thank you cPanelMichael,
I already done that long time ago but that didnt stop the spammer from hijacking my email account password.
If I already configured /etc/hosts.deny to ALL:ALL and etc/hosts.allow to allow ONLY my Ip adress, how the spammer was able access my email account with different IP adress than mine?

We need more information about the emails that were sent out to address that question. For instance, what information were you able to obtain from the mail headers or logs in /var/log/exim_mainlog?
Thank you.
Thank you.
There is no doubts the spam emails were sent from my server, when I checked (mail queue manager) in WHM there were hundreds of those emails listed and waiting to be sent as shown in the attached image.
what info do I need from mail headers or logs in /var/log/exim_mainlog? from the attachement its is obvious the spam is sent from my server and it stopped after I changed the email account password (strong one this time)

The mail headers and logs in /var/log/exim_mainlog might help explain "how" the messages were sent out (e.g. authentication or through a PHP script).
Thank you.
Thank you.
Is that a header of a message that you see in the mail queue? If you search for "determine spam source" on our forums you will see several threads that will help you through the process of how to identify the source of a SPAM message. EX:
