The Spam Assassin Spam Box is a separate mail folder called "spam". If enabled, all e-mail that Spam Assassin flags as spam is automatically delivered to the "spam" folder.
Note: You need an IMAP e-mail client, such as Horde, to view the Spam Box (refer to Webmail - Horde for more information).
To enable or disable the Spam Box:
Click on the Spam Assassin link in the Mail area.
Click on the Enable Spam Box or Disable Spam Box as required.
