To ensure email routing to your mail server, query the DNS server for the primary IP address of the corpnet.xyz domain and the mail server's IP address. Confirm the mail server information by querying an external DNS server.

Step-by-step explanation:

To ensure that email is routed from the internet to your mail server, you need to know the mail server address for corpnet.xyz. There are multiple ways to find this information:

1. You can query the default DNS server for the primary IP address of the corpnet.xyz domain. This will provide you with the main IP address associated with the domain.
2. You can also query the default DNS server for the corpnet.xyz mail server. This will give you the mail server's IP address, which is essential for routing email.
