What are MX Records?
MX (Mail Exchange) records are DNS entries that specify which servers handle incoming email for your domain. When someone sends you an email, their server queries your MX records to find out where to deliver it. Without properly configured MX records, email sent to your domain will bounce.
Each MX record has a priority number — lower numbers are tried first. PTR (reverse DNS) records verify that your mail server IPs map back to your hostname, which many spam filters require for email delivery.
