Verifying DNS Configuration
To verify that the DNS server is properly configured for UMS:
1 On a PC where you run the e-mail client, open a command window.
2 Enter this command:
nslookup umsemail
The output from the command should look something like this:
E:\UMS>nslookup umsemail
Server: galaxy.vcx.wan.3com.com
Address: 192.168.126.1
Name: umsemail.vcx.wan.3com.com
Addresses: 192.168.126.1 192.168.126.2
In this example, the domain name is resolved to two IP addresses, one for
the primary server and one for the secondary server.
3 Enter this command:
ping umsemail
Continuing with the information in this example, you would see replies
from umsemail.vcx.wan.3com.com.
