different spamassassin behaviours

Hi, thanks for your response.
There are a lot of things rising the score manually:
X-Spam-Status: Yes, score=18.1 required=5.0 tests=BAYES_50,CUSTOM_MANY_BL,
autolearn=spam autolearn_force=no version=3.4.1
All the files are taken from /sonicle/etc/mail/spamassassin and /sonicle/share/spamassassin, and they looks to be read both manually and during postfix run, as many of the mails are caught and contains X-Spam-Status with tags taken from there (sare cf files, kam file, fili_br file etc).
Also, many of the auto-learnt mails get spammed after being trained.
The bayes is configured as :
use_bayes 1
bayes_auto_learn 1
bayes_path /sonicle/var/spamassassin/bayes_db/bayes
bayes_file_mode 0777
and here are the files:
sonicle at www:~$ ls -l /sonicle/var/spamassassin/bayes_db
total 12699
-rw-rw-rw- 1 snclamav snclamav 25680 Jun 27 08:28 bayes_journal
-rw-rw-rw- 1 snclamav snclamav 10567680 Jun 27 07:58 bayes_seen
-rw-rw-rw- 1 snclamav snclamav 5128192 Jun 27 07:58 bayes_toks
here are the amavis processes:
sonicle at www:~$ ps -ef | grep amavisd
snclamav 23517 20393 0 07:43:58 ? 0:04 /sonicle/bin/perl -T /sonicle/sbin/amavisd -u snclamav -c /sonicle/etc/amavis/a...
snclamav 20393 6278 0 May 12 ? 0:49 /sonicle/bin/perl -T /sonicle/sbin/amavisd -u snclamav -c /sonicle/etc/amavis/a...
snclamav 29614 20393 0 08:28:49 ? 0:00 /sonicle/bin/perl -T /sonicle/sbin/amavisd -u snclamav -c /sonicle/etc/amavis/a...
is there any way I can run amavisd manually exactly as postfix would do during an incoming email?
I bet I need debugging output, but enabling it live may fill my mail logs, and I would have to wait for some spam to get in.
Thanks again,

RE: different spamassassin behaviours
Do you know for a fact that the bayes database is making those scores get higher when you run it in debug? If so, where is your bayes database stored and who is the owner of that path? Do you know for a fact that Amavis calls Spamassassin to scan emails?

different spamassassin behaviours
I have some installation of amavis+postfix, where I discovered that some spam is coming in with a very low score, but if I run spamassassin in debug mode on the same emails they get a very high score.
On my installations, amavisd runs under the "snclamav" user, while the smtp-amavis postfix daemons run under the "snclmail" user.
I run the bayes learn using the snclamav user, and also run spamassassin debug mode using the same user, that stores the bayes database in a specific path.
Any idea what may happen in amavisd spawn spamassassin that does not happen in manual debug mode?
Thanks for any help
