Amavis doesn´t tag messages

[Christian Hügel]

Hi,

I´ve setup amavis like described here [1] and so far I everything works 
except tagging the message like [SPAM]
In my maillog I can see that amavis recognizes the mail as spam:

kolab amavis[13640]: (13640-01) Passed SPAM 
{RelayedOpenRelay,Quarantined},

And here is my amavisd.conf lines

$sa_tag_level_deflt  = -999;  # add spam info headers if at, or above 
that level
$sa_tag2_level_deflt = 6.2;  # add 'spam detected' headers at that level
$sa_kill_level_deflt = 6.9;  # triggers spam evasive actions (e.g. 
blocks mail)
$sa_spam_subject_tag = '[Spam]';

In the mail header there should be something like this:

X-Spam-Flag: NO
X-Spam-Score: 5.558
X-Spam-Level: *****
X-Spam-Status: No, score=5.558 tagged_above=2 required=6.2 
tests=[AWL=-0.256,
      DNS_FROM_OPENWHOIS=2.431, FH_DATE_PAST_20XX=3.384, 
NO_RELAYS=-0.001]
      autolearn=no

but the spam part is missing all.
The only thing I can see what looks like amavis is:

X-Sieve: CMU Sieve 2.4
X-Virus-Scanned: amavisd-new at example.com


Do I need to change any other configuration file to get the messages 
tagged?

Thank you

Christian
