header_checks hell

I'm having trouble with a simple header check running in a pre-queue amavis
setup.
The filter should DISCARD any Subject that begins with "SPAM-Verdacht
CUSTOMERNAME:"
# Pattern Aktion
/^Subject:\ (SPAM-Verdacht CUSTOMERNAME:\ .*)$/ DISCARD $1
Postfix may read the pcre-table:
# ls -l /etc/postfix/header.chk
-rw-r----- 1 root postfix 69 25. Apr 09:20 /etc/postfix/header.chk
cleanup is running non-chrooted:
# cat /etc/postfix/master.cf | grep cleanup
cleanup unix n - n - 0 cleanup
postmap filters as expected:
# postmap -q "Subject: SPAM-Verdacht CUSTOMERNAME: Test" pcre:/etc/postfix/header.chk
DISCARD SPAM-Verdacht CUSTOMERNAME: Test
Postfix has been configured to run header_checks:
# postconf -n header_checks
header_checks = pcre:$config_directory/header.chk
Still my testmails pass the filter. When I look at the received message
everything looks as expected:
To: recipient@example.com
Subject: SPAM-Verdacht CUSTOMERNAME: Test
Message-ID: <20120425075309.GF23440@state-of-mind.de>
What is it I am missing?
# postconf mail_version
mail_version = 2.6.6
# rpm -qa | grep pcre
pcre-7.8-3.1.el6.x86_64
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.2 (Santiago)
