The message actually means "I can't receive messages for that host
(from you)". In other words, that recipient host isn't local, and
qmail isn't configured to allow the client to relay messages to it.
There are three hosts involved here: the client (sender) host, your
qmail server (relay), and the receiving (recipient) host. Back in the
good ol' days, before rampant spam, open relays were common. They'd
accept anything submitted via SMTP and either deliver it locally or
forward it on to the recipient host. By default, qmail's SMTP daemon
only accepts messages it can deliver locally or to certain
preconfigured domains. The list of hosts it'll accept mail for is
"rcpthosts".
You want to allow a small set of local hosts to use your server as a
relay for arbitrary recipient hosts. This is accomplished by following
the example in the FAQ.

The question is "How can I limit who uses my mailserver to relay to
non-local domains?" The answer in the FAQ describes how to specify
which systems can connect to your server and use it to relay to
non-rcpthosts domains.
