How to Use Nslookup to Verify MX record configuration

Basically:

C:\>nslookup

Default Server: contoso.com

Address: 10.0.0.112

> set q=MX

> microsoft.com --> domain to be searched

Server: contoso.com

Address: 10.0.0.112

Non-authoritative answer:

microsoft.com MX preference = 10, mail exchanger = mail.messaging.microsoft.com

mail.messaging.microsoft.com internet address = 216.32.180.22
