Introduction
SpamAssassin is the tool used by the mail server to check if a message is spam or not. It scans each message and checks it against hundreds of rules. Each rule is assigned a "score" (also known as the rules "weight"). The score tells SpamAssassin how important that rule is. Sometimes the default scores fail to provide the correct results. SpamAssassin may assign a "spam" result to a non-spam (ham) message, or vice-versa, if the default rules are not appropriate for a user. Fortunately, each cPanel user can adjust the weight of each rule for themselves. The cPanel user can make the changes in the cPanel account. Those changes will affect all the email accounts associated with that cPanel account.
Procedure
- Log in to the user's cPanel interface.
- In the Email section, click on Spam Filters.
- At the bottom of the page, there is a link to "Show Additional Configurations". Click it.
- The last of the newly expanded options is "Calculated Spam Score Settings". Click on the link that says "Configure Calculated Spam Score Settings".
- The link will take you to a new interface, where there are instructions and a link to 'Add a new "scores" item'.
- When you click the option to add a new score item, new boxes will appear on the page.
- The first item is a drop-down list with a list of the hundreds of rules that SpamAssassin consults. Fortunately, there is a search box. Start entering the name of the rule you want to change, and the list will narrow down until there is only one rule left so that you can click on it.
- The second item is a box with a number in it. Use the arrow keys to adjust the score, or type the new score into the box.
- Click the "Update Scoring Options" button at the bottom of the page.
