/var/svscan or whatever) directory.".
I can't get this work at all, I symlinked /usr/qpsmtpd (the directory where I installed Qpsmtpd) to /service (ln -s /usr/qpsmtpd /service), but when i type "service qpsmtpd start" I get "qpsmtpd: unrecognized service".
When the README says the "supervise tools" it is referring to Dan Bernstein's daemontools distribution:
http://cr.yp.to/daemontools.html
which is a completely different way to start and maintain daemons. It is not installed by default on any *nix distros (though I believe in the *BSD world it is available using the ports). If you had installed daemontools, the simple act of linking the directory into /service would have started both Qpsmtpd and it's matching logging process.
Visit the link above and install the software and you should be good to go...
