If you get repeated spam from any particular email address, such as a mailing list you cannot unsubscribe from, you can blacklist that domain.


Step 1: Click the ‘Spam Filters’ link on the main cPanel dashboard


Step 2: Toggle the ‘Additional Configurations (for Advanced Users)’.expand the list by clicking the “Show Additional Configurations” link.


Step 3: Click the ‘Edit Spam Blacklist Settings’ Link.


Step 4: Add a New Blacklist From Item (blacklist_from)

When configuring the blacklist_from setting, you are allowed to use wildcards such as “*” and “?”. For example:

user@example.com — Blacklists a single specified email address

*@example.com — Blacklists all of the email addresses at example.com

?ser@example.com — Blacklists a single character in the email address. So in this example, user@example.com would be allowed, but thisuser@example.com would not.


Once you have entered your Blacklists_from item, you can either add more or click the “Update Blacklist (blacklist_from)” button
