What is MX?

MX stands for "Mail Exchanger." It's a type of DNS record used to specify the mail servers responsible for receiving email messages on behalf of a specific domain. In simpler terms, it helps direct email traffic for a domain.

There can be multiple MX records, each with a priority value like 10, 20, and so on, indicating their order.

For instance, when sending an email to a user, the server associated with the MX record having a priority value of 10 is initially checked. If it cannot be reached, servers with priority values like 20 are then verified.

In order to ensure uninterrupted communication, when the email server with a priority value of 10 fails to respond, other servers will take over.

Frequently Asked Questions

The MX priority value is to specify which MX server should be accessed first for incoming emails. For both records, MX Layer sets the priority value to "10" to evenly balance the load between the two servers.

TTL, short for Time to Live, indicates how long the defined DNS record should be cached in seconds. Having this value helps prevent your server from causing extra load from queries coming from other servers.

You can check MX records using tools like 'dig' on Mac or 'nslookup' on Windows. On Mac, open Terminal and type dig mx. On Windows, open Command Prompt and type nslookup -q=mx

An MX lookup involves querying a domain's DNS to find its Mail Exchange (MX) records. These records specify the mail server responsible for accepting emails on behalf of the domain.

Open Terminal on your Mac, then type dig mx to obtain the MX records for the domain ''.

On Windows, open Command Prompt, type nslookup -q=mx, and hit enter to get the MX records for the domain ''.

A DNS lookup asks a DNS server for details about a domain or subdomain, like IP addresses (A or AAAA records) and mail servers (MX records). An MX lookup specifically finds Mail Exchange records, ensuring emails reach the correct mail server for a domain.
