pyzor checks are not in mailheader

[Ralf K. <ra...@lx...>]

Hello,

I dont know if pyzor works fine. There are no checks visible in mailheader.
Here my local.cf:
++++++++++++++++++++++++
use_pyzor 1
pyzor_path /usr/bin/pyzor
pyzor_options --homedir /var/lib/amavis/.pyzor
add_header all Pyzor _PYZOR_
score PYZOR_CHECK 4.8
++++++++++++++++++++++++

But there are no checks in mailheader:
X-Virus-Scanned: Debian amavisd-new at domain
X-Spam-Flag: NO
X-Spam-Score: -4.619
X-Spam-Level:
X-Spam-Status: No, score=-4.619 tagged_above=-999 required=5
	tests=[AWL=-0.619, RCVD_IN_DNSWL_MED=-4]

But I see no DCC Checks, but in logfile.
What I am doing wrong?
My system is debian lenny 64 bit.
I use postfix, amavis, spamassassin, pyzor, dcc.

with kind regards
Ralf
