Yes. It comes with the distribution. There's also several useful links at
www.qmail.org.
For your smtp-accepting qmail host not to be an open relay, you must meet
(at least) the following conditions:
1. control/percenthack is empty and/or does not exist
2. control/rcpthosts exists.
3. In your tcprules file for the tcpserver you use for rblsmtpd or
qmail-smtpd, you have RELAYCLIENT="" *only* for IP addresses which are
supposed to relay through your server.
If you do not meet any of these, your server will relay. If you do not
understand the statements above, you should go back to the documentation
and ask for clarification on the specific statements you do not understand.
Vince.
