关于Relay Test

AndyDavis

我在 http://www.abuse.net/relay.html 做的Relay test，使用匿名测试我的IMAIL server
前14个测试均通过，但第15个测试返回的结果是：

Relay test 15>>> RSET
<<< 250 ok its reset
>>> MAIL FROM:<spamtest@xxx.net>
<<< 250 ok
>>> RCPT TO:<abuse.net!securitytest>
<<< 250 ok deliver to alternate

Relay test resultHmmn, at first glance, host appeared to accept a message for relay.
THIS MAY OR MAY NOT MEAN THAT IT'S AN OPEN RELAY. 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. 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.

其中的xxx.net是我的IMAIL SERVER的域名。

不知道这第15个测试是什么意思？ 我的IMAIL SERVER有Open relay的漏洞吗？  我已经打开了No mail relay, 并开启了SMTP认证。

这个测试只能证明你的服务器接受了这封邮件，没有立刻拒绝接受转发请求
仅此不能证明你的服务器就是openrelay

所以它的信息中也是这个意思
