It works great; I took a few step to achieve the main goal (I'm using 
Debian etch) without disturbing the running system

1) Install clamav related packages: clamav, clamav-base, 
clamav-freshclam, libclamav3 -using volatile repository-
2) Add the newly created user clamav to the kolab-r group
3) Stop and disable clamav from the /kolab tree
4) Install clamav-daemon -from volatile repository- and check it is running

At this fase the system is already using the newly installed clamav from 
Debian

5) Install razor, pyzor, dcc and dspam (amavisd-new Debian package seems 
to use dspam even if spamassassin doesn't)
6) Install spamassassin -using the volatile repository- configure it to 
run the cron job included in the Debian package 
(etc/default/spamassassin) and to enable pyzor, razor and dcc 
(/etc/spamassasin/local.cf) and any other configuration for your own site
7) Stop and disable both spamassassin and amavis from the /kolab tree
8) Install amavisd-new -from volatile repository- and immediately change 
the port amavisd-new uses to give the message back to postfix from port 
10025 to port 10026 (edit /etc/amavisd-new/conf.d/50-user and add the 
following two lines
$notify_method  = 'smtp:[127.0.0.1]:10026';
$forward_method = 'smtp:[127.0.0.1]:10026';
This is needed because port 10025 is used to inject back mail to postfix 
from the kolabfilter
9) check amavisd-new is running and test your system!

Hope this helps

Cheers
Luca
