spamassassin: hosting service/cpanel problems user_prefs partially ignored -updated-

[Dennis German <DG...@Real-World-Systems.com>]

Updated, Thought you all might be interested  ( see ++++ updates)

My intention is to observe false negatives (i.e. spam seen as ham) and
increase the score of one or more of the tests in an effort to cause  
additional spam to be detected.

I am using a hosting service where spamassassin configuration 
is  updatable by the cPanel system.
I can also modify ~/.spamassassin/user_perfs directly.
When I list /etc there is no mail directory 
(however I believe I am not looking at the true /etc )
...
When I modify ~/.spamassassin/user_prefs to include:

	report_contact Postmaster@Real-World-Systems.com
	report_hostname Real-World-Systems.com
	required_score 4
	score URIBL_JP_SURBL 5 #was 1.5 ++++
	score URIBL_SBL 5      #was 1.5 ++++
	score URIBL_SC_SURBL 5 #was 1.5 ++++
	score URIBL_WS_SURBL 5 #was 1.5 ++++
	

spam messages subject are correctly modified to indicate *SPAM* and
the X-SPAM-Report is correctly inserted with the revised hostname and  
contact and
scores for URIBL_* are increased to 5 ++++ 
and
includes the message preview and  ((note 4.0 required))

              ...
      X-Spam-Flag: YES

The report is preceded by:
	X-Spam-Status: Yes, score=4.0
	X-Spam-Score: 40
	X-Spam-Bar: ++++

There is no X-Spam-Checker-Version header which the documentation at
http://spamassassin.apache.org/full/3.1.x/doc/Mail_SpamAssassin_Conf.html
says cannot be removed.

THE PROBLEMS:

1)Messages that are not flagged as spam have
	X-Spam-Status: No, score=-0.7
	X-Spam-Score: -6
	X-Spam-Bar: /
	X-Spam-Flag: NO

++++
Aparently these messages are added by a module in cpanel which uses
spamassassin API's to process the email.

2) adding
	 add_header all _TESTS(,)_
  has no effect on ham or spam.


3) adding
	add_header all  DGG DGG
	add_header ham  DGG DGG
	add_header spam DGG DGG
has no effect on either spam or ham

++++
Attempting to add headers via cpanel produces only
	add_header all
	add_header ham
	add_header spam

Is my syntax for 3) correct?
