Relay test 6<br>
>>> RSET<br>
<<< 220 OK<br>
>>> MAIL FROM:<spamtest@anscom.com.cn><br>
<<< 250 OK<br>
>>> RCPT TO:<securitytest%abuse.net@anscom.com.cn><br>
<<< 250 OK, recipient accepted<br>
<br>
Relay test result<br>
Hmmn, at first glance, host appeared to accept a message for relay.<br>
THIS MAY OR MAY NOT MEAN THAT IT'S AN OPEN RELAY.<br>
<br>
Some systems appear to accept relay mail, but then reject messages internally rather than delivering them, but you cannot tell at this point whether the message will be relayed or not.<br>
<br>
You cannot tell if it is really an open relay without sending a test message; this anonymous user test DID NOT send a test message.<br>
