MX

MX stands for Mail Exchange, which refers to the part of an email system responsible for directing email messages to the correct server for delivery. When someone sends an email, the MX records in the domain’s DNS settings tell other mail servers where to send the message. Think of MX records as a mailing address for digital mail; they ensure your emails reach the right destination by specifying the servers that handle incoming mail for a domain. Proper configuration of MX records is essential for reliable email communication.
