Question

Can I leave spam email in my email account INBOX?

Answer

Yes.

The "SpamBox" feature work alongside the "Spam Filter" feature. 

cPanel: Home -> Email -> Spam Filters

Option: Move New Spam to a Separate Folder (Spam Box)  (Can be enabled or disabled)

Enabled: marked email goes to the "spam" folder

Disabled: marked email stays in the "INBOX"

From inside the cPanel account, leaving "SpamBox" off will put the marked spam email in the INBOX.

To enable "SpamBox" for use server-wide, enable it in Tweak Settings. 

WHM: Home  -> Server Configuration  -> Tweak Settings

Enable Apache SpamAssassin™ Spam Box delivery for messages marked as spam (user configurable) (Turn on here)

The "SpamBox" feature is enabled by default.
