Mail Exchange (MX) records

Mail Exchange (MX) records are a type of DNS record that directs email traffic to the appropriate mail server for a domain. When someone sends an email, the sender's email server looks up the MX records of the recipient's domain to find out where to deliver the message. These records specify the priority and address of mail servers responsible for handling incoming emails, ensuring messages are routed correctly and efficiently. Essentially, MX records act as a directory that guides emails to the right destination within a domain's network infrastructure.
