Remove SA Header for non SPAM

Hello,

i run SA v 2.60, and sa-exim as
local_scan_path = /usr/local/exim/lib/sa-exim.so

i want to exclude the SA header from non SPAM mails.
I tested some configurations, but didn't succeed.

Thank you

Torsten

My current config:

SA -> local.cf

skip_rbl_checks         	1
use_razor2              	0
use_dcc                 	0
use_pyzor               	0
report_header                   1
use_terse_report                1
always_add_report               0
rewrite_subject                 0
report_safe                     0
