How to enable SpamAssassin in cPanel/WHM

Spam filters are a very important part of any mail server. ServInt VPS accounts using the cPanel/WHM control panel come with SpamAssassin as part of the standard installation. The default configuration has SpamAssassin enabled.

If you need to reenable SpamAssassin:

• In WHM, under Server Configuration on the top of the left-hand navigation bar, click on Tweak Settings.
• Click the Mail tab. 
• Select On for "Enable SpamAssassin spam filter."

Note: ServInt recommends leaving "Enable BoxTrapper spam trap" set to Off.

To force all the users on your VPS to use SpamAssassin:

• Scroll down the left left hand navigation bar in WHM to Service Configuration and click on Exim Configuration Manager.
• Select the SpamAssassin tab.
• Set "Spam Assassin: Forced Global ON" to On. 

This will filter all of your email for spam.  It will not, however, force your users to do anything with it after it's filtered. It will simply mark spam as spam, nothing more.
