I made some notes for myself last time I installed the combo you
mention. Maybe you can use some of it, maybe you can't. The patch I
refer to is a slightly edited version of the courier patch that is
included in the amavisd-new Debian package. I had to slighty adjust the
pacth here and there - otherwise it would not apply cleanly (maybe this
has changed since I did my install?).

I hope to have gotten everything written down, but I haven't yet
followed/verified my written down instructions myself yet, so there may
in fact be bits of pieces missing in this 'recipe'. Anyhow, here goes:

# Install amavisd-new with all dependencies
sudo apt-get install amavisd-new
update-rc.d -f amavis remove
update-rc.d amavis defaults 21 21

# Now fetch sources, courier patch, and rebuild
sudo apt-get source amavisd-new
sudo apt-get build-dep amavisd-new
chown -R frederik:frederik amavisd-new* (as root)
cd amavisd-new-20030616p10
cp debian/etc/amavisd.conf .
wget \
http://sentinel.dk/linux/debian/patches/amavisd-new-courier-debian.patch
cat amavisd-new-courier-debian.patch | patch -p0
cp amavisd.conf debian/etc/amavisd.conf
dpkg-buildpackage -rfakeroot -us -uc

# Install new patched package to replace the unpatched one
sudo dpkg -i amavisd-new_20030616p10-3_all.deb

## Configuration notes
# Run amavisd-new via manual start/stop (and not via courierfilter).

# In amavisd.conf:
$mydomain = 'sentinel.dk';
$daemon_user = 'amavis';
$daemon_group = 'daemon';
$pid_file = "/var/run/amavis/amavisd.pid";
$lock_file = "/var/run/amavis/amavisd.lock";
$forward_method = undef;
$notify_method = 'pipe:flags=q argv=/usr/sbin/sendmail -f \
 ${sender} -- ${recipient}';
$unix_socketname = "/var/lib/courier/allfilters/amavisd";
$unix_socket_protocol = 'courier';

# Set various file ownership and permissions.
touch /var/log/amavis.log
chown amavis:daemon /var/log/amavis.log
chmod 640 /var/log/amavis.log

chown -R amavis:daemon /var/lib/amavis
find /var/lib/amavis -type d -exec chmod 750 {} \;
find /var/lib/amavis -type f -exec chmod 640 {} \;

# Activate amavisd-new as a filter through courierfilter/filterctl.
ln -sf /usr/sbin/amavisd-new /usr/lib/courier/filters/amavisd
chmod 755 /var/lib/courier/allfilters

# Ensure that /etc/courier/enablefiltering exists and contains "esmtp".
# This is default for Debian installations, btw.

# Restart amavisd-new
/etc/init.d/amavis restart

# If clamav is not already member of secondary groups daemon and
# amavis, add it manually and restart clamav for changes to take effect.
adduser clamav daemon
adduser clamav amavis
/etc/init.d/clamav-daemon restart
