qconfirm-conf -i dir dot local host [mailbox]
qconfirm-conf’s output gives instructions on how to enable qconfirm using the directory dir in a .qmail file.
qconfirm-conf with the option -i modifies a previously created qconfirm directory dir for the use with qconfirm-inject(1) and qconfirm-notice(1). local-qnotice-ext@host is the mail address qconfirm uses to handle delivery notifications, and dot is the .qmail file that handles the address local@host.
