The most common type of mailmap you would be entering is a simple forwarding of one email alias to one email account. To do this you enter the alias you want under your domain name on the left side, such a "me@easydns-example.com", and the destination account you want the email forwarded to on the right, such as "example@isp.com". With this mailmap in place, any email sent to the alias will be forwarded by our servers to the address you specify.
