How to Create Blacklists in cPanel

An email blacklist contains domains and IP addresses identified as sources of spam. By using Spam Filters, you can create your own blacklist to block unwanted messages before they reach your inbox. This feature allows you to flag and filter spam as incoming emails arrive on the server.

Follow the steps below to configure Spam Filters in cPanel:

1. Log in to your Bluehost Portal.
2. Click Hosting in the left-hand menu.
3. In the hosting details page, click the cPanel button.

   
    

4. Your cPanel will open in a new tab.

   
    

5. Navigate to the Email section and click the Spam Filters icon.

   
    

6. On the Spam Filters page, locate and expand Additional Configurations.

   

7. Scroll down to the Blacklist section.

   
    

8. Click the Edit Spam Blacklist Settings link.
9. Select Add a New “blacklist_from” Item.

   
    

10. Enter the domain name or IP address you want to block. Replace the example values (such as 123.45.67.80 or [email protected]) with the appropriate details.

    
     

11. Click the Update Blacklist (blacklist_from) button.
