RE: Another false negative

2007-03-19 Thread Rocco Scappatura
  what it can be the reason of the different score assigned?
  why the second system doesn't assign an AWL score?
 
 They give different Bayes scores so the Bayes databases have 
 been trained with different messages.  Do you have autolearn 
 switched on?

#   Bayesian classifier auto-learning (default: 1)
#
# bayes_auto_learn 1

Do I have to set it to 0?

But Then how I have to instruct Spamassassin? What is the best way? Do I
have a spam folder to instruct SA?

 And you must understand that the Bayes system is not a one 
 shot and you have if fixed kind of system.  Just training a 
 single message will alter the scoring, but you may also need 
 to train it with a few similar messages for it to 
 significantly change its scoring.

You're saying right. Now I understand. 

Thank you,

No, but that may explain why the two servers have different Bayes scores 
for similar messages.  If they receive different message streams they 
will be learning a different view of the email world.



But Then how I have to instruct Spamassassin? What is the best way? Do I

I don't think you need to turn off autolearn, you may want to adjust 
your threshholds, mine are set to this:


bayes_auto_learn_threshold_nonspam -0.1
bayes_auto_learn_threshold_spam 12.0

I have autolearn switched on, but I also manually train with false 
negatives, and I occasionally train a bunch of recent ham as ham.

shot and you have if fixed kind of system.  Just training a

 If you can post the full email (headers and body), I'll run it over my
 system which has lots and lots of third party add on rules from
 www.rulesemporium.com and others and see if I can make SA 
 score it high
 enough for Amavisd-new to block the email..

Thanks.

Assuming this is your score line:

 X-Spam-Status: No, score=2.5 required=5.0
 tests=AWL,BAYES_50,HTML_30_40,
 HTML_MESSAGE,HTML_TEXT_AFTER_BODY,MIME_HTML_ONLY,SARE_PROLOSTOCK_SYM3
 autolearn=no version=3.1.8

Then the biggest difference is that my Bayesian scoring gives it a 
BAYES_99 score and your's gives it a BAYES_50 score.

 Assuming this is your score line:
 
   X-Spam-Status: No, score=2.5 required=5.0   
 tests=AWL,BAYES_50,HTML_30_40,   
 HTML_MESSAGE,HTML_TEXT_AFTER_BODY,MIME_HTML_ONLY,SARE_PROLOSTOCK_SYM3
   autolearn=no version=3.1.8
 
 Then the biggest difference is that my Bayesian scoring gives it a
 BAYES_99 score and your's gives it a BAYES_50 score.

So you are saying that I have to train SA?

That would be how you would improve your Bayes accuracy, yes.

I have trained SA on my server but I still get a score lower than 5.0..

what it can be the reason of the different score assigned?
why the second system doesn't assign an AWL score?
