The term e-mail forwarding refers to an e-mail message being forwarded from a receiving address to a third-party address which is not mentioned as a recipient. For example, a client sends an email from their personal mail box to email@example.com and as far as they're involved, this is the single receiver. If there is an active forwarding, the message can be forwarded to firstname.lastname@example.org, for example, although the customer in no way meant the message to be sent there and might not be aware of the existence of this mail box. There are various purposes for using such forwarding. For example, if you have many emails it is possible to forward them all to a single mail box, which will make keeping track of e-mails easier and allows you to receive emails and respond on time. The function can also be used if a number of people should receive a copy of an e mail message sent to a standard email address.
