Please note that you have just installed qmail-sf on /var/qmail/bin/qmail-sf Before using it you need to properly create the MySQL database. A customized SQL sample was installed on /usr/local/share/doc/softfail/softfail.sql You can use this sample as root user for MySQL: mysql -uroot -p < /usr/local/share/doc/softfail/softfail.sql To use it you should configure SMTPEXTFORK's enviroment variable on qmail according to the instructions available on /usr/local/share/doc/softfail/README You are also suggested to add the following entries to /etc/crontab: @daily root /usr/local/bin/rotate-softfail-db @daily root /usr/local/bin/rotate-softfail.sh I can do it for you. Just type `make crontab-entry' if you wish me to add it.
