How to Adjust Spam Threshold Score using Spam Filters in cPanel
Introduction
This Knowledge Base article provides a concise, step-by-step guide on How to Adjust the Spam Threshold Score using Spam Filters in cPanel. The Spam Threshold Score determines how aggressively Apache SpamAssassin identifies and marks emails as spam. A lower threshold score (such as 1) is more aggressive and may label legitimate emails as spam, while a higher score (such as 10) is more passive and only flags obvious spam messages. Adjusting this score helps you fine-tune spam detection to match your specific needs and reduce false positives or negatives.
