nslookup解析是好的。


最近我的服务器出现比较多的退信，退信内容如下：
This Message was undeliverable due to the following reason:

Your message was not delivered because the Domain Name System
(DNS) for the destination computer is not configured correctly.
The following is a list of reasons why this error message could
have been generated. If you do not understand the explanations
listed here, please contact your system administrator for help.

- The host does not have any mail exchanger (MX) or
address (A) records in the DNS.

- The host has valid MX records, but none of the mail
exchangers listed have valid A records.

- There was a transient error with the DNS that caused
one of the above to appear to be true.

You may want to try sending your message again to see if the
problem was only temporary.

请问能不能告诉我怎么解决？

你服务器上面能正常解析吗？

我前面已经说了，我用NSLOOK测试是好的

你用nslookup能看到他的MX记录吗？

这是liebert.com 的信息

liebert.com     nameserver = AUTH40.NS.UU.NET
liebert.com     nameserver = NS1.liebert.com
liebert.com     internet address = 65.209.187.222

liebert.com     nameserver = AUTH40.NS.UU.NET
liebert.com     nameserver = NS1.liebert.com
AUTH40.NS.UU.NET        internet address = 198.6.1.18
NS1.liebert.com internet address = 65.209.187.63

偶没有看到MX记录~~~~~~~
肯定是不行的了呀~~~~~

我是执行命令nslookup -q=mx liebert.com  202.96.134.133
执行的结果是MX记录是全的。

#nslookup
    #set type=mx
    #not resolution domain name
    结果不可解析，就想办法通知它的网管。
   这个问题挺常见的，以前的dns server 版本比较低的，写的时候不规范，对会和高版的nds server不兼容，会出现为题的。
