What command finds only mail server records

To find only mail server records (also known as MX records) using the dig command, you can use the following syntax:

dig +short mx example.com

This will return only the MX records for the domain example.com.

Here's a breakdown of the options used:

• +short: This option tells dig to display only the answer section of the DNS response, which contains the actual record data. By default, dig displays the entire DNS response, including the header and additional sections.
• mx: This specifies the type of record to query for. In this case, we're looking for MX records.
• example.com: This is the domain name for which we want to retrieve the MX records.

You can also use the -t option to specify the record type explicitly:

dig -t mx example.com +short

This will achieve the same result as the previous command.

Note that if you want to retrieve all DNS records for a domain, including MX records, you can use the following command:

dig +short example.com

This will return all DNS records for the domain, including A records, NS records, SOA records, and more.
