Shows total scans, auto-protect scans and Spam scans number increasing, but Premium Anti-spam numbers are all 0.

Did all the steps in doc 2007020615531854 - it worked for 20 messages, then stopped filtering spam again.

No event log errors from Symantec.
Starting having the issue out of the blue on 6.0.4.something - upgraded to Version 6.0.9.286 in troubleshooting.

Ideas?
