To make a little how to for other users:
apt-get install poppassd (courierpassd, is not necessary)
probally openbsd-inetd will be installed too
/etc/init.d/openbsd-inetd restart
Now check if the deamon is there
root@server:/etc# netstat -lnpt | grep 106
tcp 0 0 0.0.0.0:106 0.0.0.0:* LISTEN 15716/inetd
