When procmail runs/calls SA, it calls it as the user to which the mail is 
being delivered, not as root.  As a result, the root bayes database 
doesn't enter into play.

Instead, your cron job should be run either A) as the user for whom you 
wish to train the database or B) call the sa-learn through something like:

su user "-c sa-learn --ham/spam/etc /path/to/ham-spam-etc.file
