mjesec installation of dspam

sudo apt-get install dspam libdspam7-drv-pgsql

Automatic installation using PostgreSQL doesn't really work, so we will do it manually:

createuser dspam
createdb --owner dspam --encoding utf-8 dspam

cd /usr/share/doc/libdspam7-drv-pgsql
psql dspam dspam < pgsql_objects.sql
psql dspam dspam < virtual_users.sql
