How to use the spam system:

If the system has determined that an email is spam, it will alter the subject to include “***Spam***”. These messages will arrive in your inbox. Using your favorite email program, you may be able to create a rule to move these to a different folder so they can reviewed at a later time.

You can also change how aggressive the filter will be as well as if spam should automatically be deleted instead of delivered to your inbox, all in cPanel.
