dog: Specify a specific DNS server to query (e.g. Cloudflare).

$ dog ${example-com} MX @${1-1-1-1}

try on your machine

This command is using the dog command-line tool to query the MX (Mail Exchanger) records for a specific domain. Let's break down each part of the command:

dog: The dog command is a DNS (Domain Name System) lookup tool that allows you to query DNS records.
${example-com}: This is a placeholder for the domain name you want to query the MX records for. You would replace ${example-com} with the actual domain name you want to check, for example, example.com.
MX: This argument specifies that you want to query the MX records specifically, which are responsible for indicating the mail servers responsible for accepting incoming email for a domain.
@${1-1-1-1}: This is another placeholder, but it represents the DNS resolver you want to use for the lookup. The IP address 1.1.1.1 is a popular public DNS resolver provided by Cloudflare, but you can replace it with any DNS resolver of your choice.

So, when you execute this command with the appropriate replacements, you will receive the MX records for the specified domain, using the specified DNS resolver.
