An MX record ( Mail Exchanger Record ) is a record in the Domain Name System (DNS) that specifies which mail servers are responsible for accepting and processing email for a particular domain. MX records determine where email messages addressed to a particular domain should be sent. MX records ensure that emails are delivered to the correct mail servers for processing by recipients.
When a sender sends an email to an email address, the sender's system uses DNS to determine the MX records of the recipient's domain. The email is then sent to one of the mail servers specified in the MX records. The mail server that receives the email processes it and delivers it to the recipient's mailbox.
Preference is a numeric value that indicates the priority czech republic email list of each mail server in the MX record. The lower the number, the higher the priority. If there are multiple MX records with the same priority, the sender will try to deliver the message to all of these servers equally.
Address (Exchange) is the domain name of the mail server that should handle mail for this domain. Typically, the address is a fully qualified domain name (FQDN) in the format "mail.example.com" or "smtp.example.com".
Example of MX record:example.com. IN MX 10 mail.example.com.
In this example, the domain " example.com " has one MX record with a priority of 10 , indicating that the mail servers responsible for handling mail for this domain are located at " mail.example.com ".
MX records are configured by domain administrators using the DNS control panel or hosting provider and are an integral part of setting up email for a domain.
