邮件被退回的问题

royzhang

我有好几封邮件被对方的邮件服务器退回。<br>
我从exchange上看到被发送出去了。<br>
提示我的错误代码是：<br>
1。 The message cannot be delivered due to a configuration error on the server. Please contact your Administrator.<br>< mail7.gconnect.net #5.3.0 X-Unix; 73><br>
2。 Sent <<< HELO server_gw<br>
Received >>> 501 syntactically invalid helo argument(s)<br>
3。 Sent <<< RCPT TO:<cairb@asp168.com><br>
Received >>> 550 5.7.1 unable to relay for cairb@asp168.com<br>
4。 Sent <<< .<br>
Received >>> 553 5.5.4 host name(server_gw) is not match with your ip(xxx.xxx.xxx.xx), maybe it's bogus.<br>
<br>
请高手指点！在线急等！<br>

你得在exchange的smtp里的FDNS名改名为server_gw.youdomain.com<br>
在DNS服务器里加一条记录server_gw.youdomain.com,对应IP为xxx.xxxx.xxxx.xxx
