標題: 關于163.com的MX記錄不能獲取的問題！ [打印本頁]

標題: 關于163.com的MX記錄不能獲取的問題！
本周一開始，公司的郵件服務器投遞到163.com的郵件都被退回，仔細分析了一下，發(fā)現(xiàn)不能獲取163.com的MX記錄。用nslookup查看，信息如下：
[root@redhat-mail root]# nslookup
> set q=mx
> 163.com
;; connection timed out; no servers could be reached

我如果直接指到深圳電信的DNS服務器上，則可以正常獲取。

除了163.com和126.com，其它的都正常。
何解？

建議用DIG測試

應該是你使用的DNS有問題！

用DNS要選大品牌……

最郁悶的問題就在這里，能夠拿到域名，但是拿不到IP地址。

正常的情況下，應該是這樣吧：
