There seems to be an inordinate amount of misinformation on the list lately.
None of the qmail programs that depend on listening for network connections
(qmail-smtpd, qmail-pop3d, qmail-qmqpd, qmail-qmtpd) can run as a standalone
daemon. They don't know anything about packets, sockets, TCP/IP, etc. All they
can do is read from standard input and write to standard output and standard
error. They must be run from inetd, tcpserver, or the like.
The qmail programs that are long-running daemons (qmail-send, qmail-lspawn,
qmail-rspawn) it wouldn't make any sense to run under tcpserver.
