Relay test

[Paco Martinez]

Hi all !!!!   I have put Qmail in my PC and I'd like to know how to avoid my PC from spammers.   Imagine that IP address is 192.168.1.1   I have checked PC using URL: http://www.abuse.net/cgi-bin/relaytest?ADDR=192.168.1.1&ALIAS=YES   and I have obtained this message:   Relay test 8 >>> RSET <<< 250 flushed >>> MAIL FROM:<spamtest@[192.168.1.1]> <<< 250 ok >>> RCPT TO:<"[EMAIL PROTECTED]"> <<< 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)   Relay test 9 >>> RSET <<< 250 flushed >>> MAIL FROM:<spamtest@[192.168.1.1]> <<< 250 ok >>> RCPT TO:<"relaytest%abuse.net"> <<< 250 ok   Relay test result Hmmn, at first glance, host appeared to accept a message for relay. THIS MAY OR MAY NOT MEAN THAT IT'S AN OPEN RELAY.   As you see "Test 9" shows that my PC has a security hole !!!! How can I avoid PC from that unsecurity case ???   Thank you very much !!!
