autolearn problem

[David Jiménez Domínguez <dj...@correo.seguridad.unam.mx>]

Hi lists!!

I'm using Amavis-New with SA and Postfix. When I check the Spam in the
quarantine directory, all the messages doesn't have the autolearn label in the
headers (Neither autolearn=no, nor autolearn=SPAM / HAM). This is my local.cf:

require_version         2.63
required_hits           5.0
rewrite_subject         0
subject_tag             *****SPAM*****
report_safe             1
use_terse_report        0
use_bayes               1
bayes_auto_learn        1
bayes_auto_learn_threshold_nonspam      0.1
bayes_auto_learn_threshold_spam         10.0
bayes_min_ham_num       200
bayes_min_spam_num      200
bayes_path      /var/amavis/.spamassassin/bayes
bayes_file_mode 0770
auto_learn              1
rbl_timeout             8
use_razor2              0
use_dcc                 0
use_pyzor               0
ok_languages            en es
ok_locales              en

and this is an Spam header...

X-Spam-Status: Yes, hits=11.8 tag1=-999.0 tag2=3.0 kill=5.0 tests=ALL_NATURAL,
 BANG_GUARANTEE, BAYES_99, HTML_FONTCOLOR_RED, HTML_FONTCOLOR_UNSAFE,
 HTML_FONT_BIG, HTML_MESSAGE, MIME_HTML_ONLY, MONEY_BACK
X-Spam-Level: ***********

What is wrong??? Please help me

The pre-Bayes score is not over 10.0, which is your threshold for 
autolearning.  Without parsing the individual scores, keep in mind you 
have to have a certain number of points from header and body tests also 
- it looks like you have 0.0 from headers.

Under amavis spamassassin does NOT generate the message headers or tagging, 
this is ENTIRELY done by amavis itself, which only uses information that SA 
provides.

Thus, the inclusion or not of an autolearn header is an amavis feature.

Also, for reference the example message in question would not have been 
autolearned. The autolearn threshold is 10, the TOTAL message score was 
11.8, but the pre-bayes score was substantially lower. Autolearning is done 
based on calculating the message score as if bayes was entirely disabled 
(no BAYES_* rules, and the appropriate change to using scoreset 0 or 1 is 
made). This score can be vastly different from the total score.

Autolearning as spam also requires at least 3 points from header tests, and 
this message had 0, so it wouldn't have learned for that reason as well.
