This guide explains how to block spam email using cPanel security settings.
Spam email can quickly clutter inboxes, consume mailbox storage, and negatively affect productivity. In more serious situations, spam emails may contain phishing links, malware, or fraudulent content designed to compromise user accounts or steal sensitive information.
cPanel includes built-in spam filtering and email security tools that help block unwanted emails before they reach your inbox. Properly configuring these settings improves email reliability, enhances security, and reduces the risk of malicious messages reaching users within your domain.
