If you have your own server or VPS then you really should consider installing CSF firewall.
Once CSF firewall is installed, blocking an IP is really simple.

You can block specific domains in cPanel>>Email>>Spam Filters by adding the domain to the blacklist (you need to have SpamAssassin enabled for this)

In v84 cPanel/WHM we are introducing a server-wide domain block in WHM>>Service Configuration>>Exim Configuration Manager -> Blocked Domains
