Introduction

Effectively managing email communication is critical in maintaining a secure and clutter-free inbox, especially for web hosting environments. In cPanel, administrators and users can leverage built-in spam filtering tools to control which email addresses are allowed (whitelisted) and which are blocked (blacklisted). This feature helps ensure that essential communications are not mistakenly marked as spam while preventing malicious or unwanted emails from reaching user inboxes.

This guide will walk you through the process of configuring both whitelisting and blacklisting rules directly within cPanel’s Spam Filters section. The steps outlined here are suitable for website owners, administrators, and users who manage their email settings in cPanel.

Prerequisites

• Access to cPanel with administrative or user-level privileges.
• Basic understanding of how email whitelisting and blacklisting functions.
• A list of specific email addresses or domains you intend to whitelist or blacklist.
