How-to Blacklist & Whitelist email addresses using Spam Filters in cPanel

We describe how you can blacklist and whitelist email addresses and domain names using Spam Filters (powered by SpamAssassin™) in cPanel.

Blacklisting an email address will block emails from the sender from reaching your inbox.

Whitelisting and email address will mean emails will bypass the Spam Filters and will be delivered to your email account inbox.
