Testing the name server lookup

Use the Name Server Lookup test to determine whether you can look up a system using the domain name servers assigned on the Network Configuration Web page. If the system can look up domains, the system can also deliver messages to these domains.

Run the Name Server Lookup test for the Messaging server and the mail gateway.

Procedure

On the Administration menu, click Messaging > Diagnostics > Name Server Lookup.
The system displays the Test Name Server Lookup Web page.
Enter the Internet host name or IP address of the system for which you want to run the test.
In the Select DNS Server field, select a DNS server.
In the Record Type field, select the type of information that you want to retrieve.
Click Run Test.
The system displays the test results.
