I will experiment with this and post my results.
The user .procmailrc file is in the /home/e-smith/files/users/[username] directory.
I used WinSCP to browse to this file and edit it.
Scroll down to the bottom of this file and add just above the last entry (all else goes to inbox)

* ^X-Spam-Status: No

This worked fine for me right away, without having to reboot etc.
There are other rules in this .procmaailrc that can be changed like what to do with positive spam hits or spam hits over 15 score.
These changes only apply to the user of whatever the .procmailrc file you have just changed.
