qmail-conf is a collection of tools for setting up various qmail services. They are like *-conf programs in djbdns. With qmail-conf, for example, setting up a minimal SMTP service takes the following four steps: # qmail-smtpd-conf qmaild qmaill /var/qmail/service/smtpd # cd /var/qmail/service/smtpd # make # ln -s /var/qmail/service/smtpd /service qmail-conf assumes that (recent versions of) daemontools and ucspi-tcp have already been installed. It also assumes that svscan is already running. qmail-conf tries to provide reasonable defaults: it avoids DNS reverse lookups; it avoids IDENT lookups; it lets TCP connection attempts be logged with multilog; and for POP3 and QMQP, connection attempts are denied unless you explicitly authorize your clients.
