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