Setting Threshold

[Jerry Malcolm]

I am setting up SA on an AWS Linux EC2.  I am trying to change the 
results threshold from 5.0 to 4.0.  I went to 
/usr/share/spamassassin/local.cf, uncommented and changed: 
"required_score 4.0".  But when I stop and start the service and process 
an email through it, headers still say 5.0 as the threshold.  What am I 
doing wrong?  Is there some other place I need to change it as well?

Thx.
