www.abuse.net test and mail Qmail server - Help

[Roberto Samarone Araujo \(RSA\)]

        Hi,

            I was testing my qmail server against relay ... I went to
www.abuse.net/relay.html and asked to test. The test returned me that my
email server is  accepting relay :( . Look at the last result of the test :

Relay test 6

>>> RSET
<<< 250 flushed
>>> MAIL FROM:<[EMAIL PROTECTED]>
<<< 250 ok
>>> RCPT TO:<[EMAIL PROTECTED]>
<<< 250 ok

Relay test result
Hmmn, at first glance, host appeared to accept a message for relay.

                Does anyone could please help me to set up my qmail in order
to block this ?

                                    thanks
