MX records are for identifying where email for your domain should be delivered. For example, if your domain name is example.org and you want to receive email at the address me@example.org, you have to create 3 MX records for the domain example.org.
An MX record has several parts:
example.org). In the May First control panel, this is referred to as the "fully qualified domain name" or FQDN for short. Some DNS providers (like Cloudflare) just have an @ sign to represent the domai name. Always use your root domain - e.g. example.org, you do not need an MX record for www.example.org.a.mx.mayfirst.org, b.mx.mayfirst.org. and c.mx.mayfirst.org (a separate MX record for each server). NOTE: If your MX record is currently pointing to a May First server that is not a.mx.mayfirst.org, b.mx.mayfirst.org org, and c.mx.mayfirst.org, please check with support before changing it.Follow our guide for more information about adding DNS records via the May First control panel..
