What does Email forwarding mean?
Email forwarding is actually a feature that various DNS providers supply. Its main purpose is to redirect the incoming traffic of one email address to another. The interesting part is that it is performing that on a domain level, and there is no need for additional special software.
It is important to understand that it is a separate feature. Moreover, it is different from an email user that transfers a message to someone else or the email forwarding element of Gmail and Outlook.
In case you are administrating the domain name, you are able to redirect the incoming emails from one of the email addresses using the domain name and transfer them to an individual email address.
