the x-spam-status headers should always be present Spam or not. So what you are 
saying is that the x-spam-status headers are not present when email goes 
through normally or when they are run manually?

Can you paste your amavis config here?

Subject: [SUSPECTED SPAM]RE: different spamassassin behaviours

The x-spam-status headers on that cases are not present, because the score is 
too low, and is considered non-spam.
Is there any way I can force the injection of the x-spam-status header even for 
low scores? This may help.

I meant that all the cf files (the rules files) are taken from the same place 
by spamassassin, both manually and automatically during postfix injection, as I 
can see it from the spam taken.

And finally, yes, I can find the logs you say, where the mail (that manually 
scores 18.0+) passes as "CLEAN" in amavis and back into postfix.

I attach an example email, and here is the relative log while passing in:

Can you provide the x-spam-status headers for the same email when run through 
Postfix normally and then manually so we can see the differences?


Also, I'm a little confused, what do you mean when you say " All the files are 
taken from /sonicle/etc/mail/spamassassin and /sonicle/share/spamassassin"?

Also, in your mail log, do you say a lines similar to below? The first one is 
Amavis passing the message as CLEAN and then re-injecting it back to Postfix on 
port 10025 for delivery. Your port config may vary.

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,
HTML_FONT_LOW_CONTRAST,HTML_MESSAGE,MIME_HTML_ONLY,RCVD_IN_DNSBL_INPS_DE,
RCVD_IN_HOSTKARMA_BL,RCVD_IN_MSPIKE_H2,RCVD_IN_UCEPROTECT2,
RCVD_IN_UCEPROTECT3,RCVD_IN_WPBL,SPF_HELO_PASS,TVD_RCVD_SPACE_BRACKET,
T_REMOTE_IMAGE,UNPARSEABLE_RELAY,URIBL_ABUSE_SURBL,URIBL_DBL_SPAM
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@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@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,
Gabriele

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?

Subject: different spamassassin behaviours

Hi,

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

Gabriele
