One-to-one email mapping, also known as domain-to-domain email forwarding, provides a simple, easy-to-configure mechanism to forward all email addresses at one domain to the same email addresses at some other domain. The destination domain need not reside on easyDNS, it can be anywhere.
When setting this up the mapping will be quite straight-forward, here we show the mechanism mapping email destined for easydns.co to their corresponding addresses on easydns.com
This is handy when migrating between domain names or when you want to guard against lost email inadvertently sent to typos of your main production domain (provided you have registered those names, .co is a good one to grab in this respect).
