OK, so you want your qmail system to relay for the web server (and
maybe other systems in your domain) but not for everyone on the
net. By default, qmail doesn't relay: it delivers mail from or to
local addresses, but rejects attempts by remote hosts to submit mail
for other remote hosts.
Using tcpserver to set the RELAYCLIENT environment variable for
qmail-smtpd *only* for connections from hosts designated as relay
clients (like your web server) will cause qmail-smtpd to ignore the
control/rcphosts file and, therefore, act as a relay.
