Hi. This is the mailer daemon at mxvip20.hichina.com.<br>
I'm afraid I wasn't able to deliver your message to the following addresses.<br>
This is a permanent error; I've given up. Sorry it didn't work out.<br>
<br>
<carrie@aol.com>: I'm not going to try again; this message has been in the queue too long.<br>

下面是NY OFFICE给我们的邮件，似乎是要向电信申请反向域名解析 服务，公司用的是ADSL<br>
Recently NY office is having trouble in receiving e-mails from Sha Hoza office to our AOL address. I finally found out from AOL today that they are taking several new procedures in order to filter spams from normal e-mails. One of this procedure requests that the Domain Host or ISP (Internet Service Provider) of the e-mail sender must enable "Reverse DNS Record" in their MX Record. So please contact your ISP to have that record set up or enable, otherwise all mails sent from Hoza Sha will always be treated as spam and rejected for delivery.

动态ＩＰ吗？建议不要使用这种方式。因为国外把中国大部分ＡＤＳＬ的ＩＰ段列为了垃圾邮件地址

你的MX记录没有做好吧<br>
