What Are MX Records?
MX (Mail Exchange) records are DNS records that specify which servers handle email for a domain. When someone sends an email to user@example.com, their mail server looks up the MX records for example.com to find where to deliver it.
MX Record Priority
Each MX record has a priority number (lower = higher priority). Mail servers try the highest-priority (lowest number) server first and fall back to others if it's unavailable.
