MX
MX (Mail Exchange) records tell other email servers which servers are responsible for accepting incoming email for your domain. These records are essential for receiving email at your domain.
When someone sends an email to your domain (e.g., user@yourdomain.com), their email server looks up your domain's MX records to determine where to deliver the message. MX records include the hostnames of the mail servers that will accept email for your domain listed in a priority order.
If you want to receive email through Mailcast, you'll need to update your MX records to point to our mail servers. This ensures all incoming email is properly routed through our system for processing.
