If there are problems like

1) "cy@vip.163.com: domain [vip.163.com] MX/IP resolved failed"

2) "domain [day.com.cn] MX/IP resolved failed"

But the MX was resolved correctly. Then it may because that the DNS can't find the MX/IP. The solution is as follows.

In the "Local Area Connection" dialog box, modify the DNS address. It can be modified as

8.8.8.8

8.8.4.4

4.2.2.1
