Pop clients (such as Outlook): Your mail program has a way to subscribe to your new folders. Please refer to the help section of your program.
Note: The SpamAssassin feature SpamBox recognizes the folder name 'spam' in all lowercase, and not 'Spam'. If the folder name is 'Spam', the intended mail will not be delivered to the correct folder.
If a spam folder does not already exist, you will need to create and subscribe to it.
Visit the cPanel webmail interface and choose SquirrelMail.
Click on the Folders link at the top of the page.
Under Create Folder, enter the name 'spam' for the new folder.
If the folder does not automatically list itself in the Subscribe list under the Unsubscribe/Subscribe area, you will need to manually subscribe to the folder by selecting the spam folder and clicking Subscribe.
In Horde, at the top, click on the gear icon and then hover over Preferences and click on Mail.
