一个客户,发信给我,他收到的退信内容:<br>
<br>
Hi. This is the qmail-send program at smtp1.hksmtp.com.<br>
I'm afraid I wasn't able to deliver your message to the following<br>
addresses.<br>
This is a permanent error; I've given up. Sorry it didn't work out.<br>
<br>
<sales5@XXX.com>:<br>
Connected to 210.51.172.140 but greeting failed.<br>
Remote host said: 451 Audit system deny remote ip<br>
I'm not going to try again; this message has been in the queue too long.<br>
<br>

这个问题给那邮件服务代理商,解决了半天,没回音!<br>
不知那位仁兄知道的!<br>
