The term email forwarding refers to an e-mail being forwarded from a receiving address to a third-party address which is not mentioned as a receiver. For example, a client sends an email from their personal mail box to firstname.lastname@example.org and as much as they're involved, this is actually the single receiver. If there is an active forwarding, the message can be forwarded to email@example.com, for instance, even though the customer in no way intended the e-mail to be sent there and might not be aware of the existence of this mailbox. There are numerous purposes for applying such forwarding. For instance, if you've got various e-mail addresses it is possible to forward all of them to a one email address, which can make monitoring e-mails easier and allows you to collect e-mails and respond timely. The feature could also be used in case a number of people should get a copy of an e-mail message sent to a standard email address.
