Problem with spam quarantine

Hello list,
I have a mail gateway server running
Postfix/Amavisd-new/clamav/spamassassin. It's a VM (on KVM host) running
Centos 5.8 with:
postfix-2.9.1-1.pcre.sasl2.dovecot.rhel5
amavisd-new-2.4.5-1.el5
clamav-0.97.5-1.el5
clamav-db-0.97.5-1.el5
spamassassin-3.3.1-2.el5
My problem is I want to quarantine spam mail rather than totally discard
it, however, although (I think) I have followed directions/manual, spam
is not being quarantined.
My config is at the end of this message (as well the server
initialization log). As you can see, I am using:
$final_spam_destiny = D_DISCARD;
and:
$spam_quarantine_method = "local:spam/spam-%n-%m-%i" ;
without success.
I had also tried:
$spam_quarantine_method = "local:/var/blockedmail/spam/%n-%m-%i" ;
(and other things) also without success.
What am I doing wrong?
Here is the session of a test spam mail (with the well-known
spam-designation content: "XJ...34X"), as logged in /var/log/amavisd.log:
