MX record
An MX record, which stands for Mail Exchange record, is a type of DNS record that specifies the mail server responsible for receiving email messages on behalf of a domain. In other words, MX records help route emails to the correct mail servers based on the recipient's domain.
MX records play a crucial role in the email delivery process by directing incoming emails to the appropriate mail server. When someone sends an email to an address within a specific domain, the sender's mail server queries the DNS system to find the MX record associated with that domain. The MX record contains information about the priority of the mail servers that can receive emails for that domain. The sender's mail server then uses this information to deliver the email to the correct mail server.
MX records can be configured with multiple entries, each with a different priority level. This allows for redundancy and failover in case one mail server is unavailable. The priority level determines the order in which mail servers should be contacted - the lower the priority number, the higher the priority. If the highest-priority mail server is unreachable, the sender's mail server will attempt to deliver the email to the next highest-priority mail server.
