MX

Mail Exchanger

A type of resource record in the Domain Name System (DNS) that specifies a mail server responsible for accepting email messages on behalf of a recipient’s domain. A domain may have multiple MX records, typically arranged with a priority ranking indicating the order in which the mail servers should be tried. Key Points about MX Records:

• Priority: MX records have a priority number (or preference). Lower numbers denote higher priority, guiding the order in which servers should be contacted.
• Server Identification: They identify the server’s hostname that will handle the emails for the domain.
• Redundancy and Load Balancing: Multiple MX records allow for redundancy and distribution of email delivery load.

Updating your MX records may cause email delivery issues, and should only be done with great caution.
