Email suffix mx stands

The MX (Mail Exchanger) record is a type of DNS (Domain Name System) record that specifies the mail server responsible for accepting email messages on behalf of a domain.

In other words, the MX record tells the world which mail server is responsible for receiving and processing email messages sent to a particular domain.

Here's a breakdown of the MX record:

For example, if you have a domain called example.com, your MX record might look like this:

MX IN 10 mail.example.com MX IN 20 mail2.example.com

In this example:

When an email is sent to example.com, the sending mail server will look up the MX record for example.com and try to deliver the email to the mail server with the lowest preference value (in this case, mail.example.com). If that mail server is unavailable, the sending mail server will try the next mail server with the next lowest preference value (in this case, mail2.example.com).

I hope that helps!
