Your domain’s MX or Mail Record controls where email that is sent to your domain will go.
If MX0 has the value "mail.yourdomainnamehere.com," this tells all email addressed to your domain to go to your domain’s mail server where you can pick it up.
You may have multiple MX records assigned to your domain. For example MX10, MX20 and MX30, may also be assigned a mail server. This is a fail-safe measure you can use in the event your default mail server is down. The alternate mail servers will store your email messages until your default server is back online. This prevents loss of email during your main mail server’s downtime. This is called MX Priority. The lowest number MX record is the first one attempted for delivery.
