The term email forwarding describes an email message being forwarded from a recipient address to a third-party address that's not listed as a receiver. For instance, a customer sends an e-mail from their personal mail box to email@example.com and as much as they are concerned, this is the only recipient. If there's an active forwarding, the message can be sent to firstname.lastname@example.org, for example, although the customer never intended the message to be sent there and may not be aware about the existence of this mailbox. There are various purposes for applying such forwarding. For instance, if you've a number of e-mail addresses it is easy to forward them all to a single email address, which will make monitoring email messages easier and will permit you to receive emails and respond to them timely. The function could also be used in case a number of people should receive a copy of an electronic message sent to a standard mailbox.
