Siteworx vs. Horde - Spam

Which takes precedence?

If I have Spam Score Threshold set to 4 in Siteworx, and one of my mailboxes is set to 10 within the Spam setting of Horde, the mail headers always show a X-Spam-Status of required=10.0

Does it always use the Horde setting? If so, how would I go about turning it off within Horde? … seems you can’t do a save with the setting being blank.
