When you've got an e-mail and you enable forwarding for it, all of the inbound emails will be sent to a third-party email address of your choosing. The e-mail sender won't be aware of this and he will be sending the message to the first address. This type of feature is useful in case you have several sites, each one with a different e-mail address for contact, for example. By forwarding all messages to one email address, it will be easier for you to keep a record and not overlook a message because you have neglected to check on a certain email address. For those who run an enterprise, you’ll be able to employ this function to watch the emails received by different departments. A further benefit is the fact that you can make use of an official e-mail address for a number of needs, let’s say admin@your-domain.com, and you can now get all of the e-mails sent to it inside your private mailbox. It's also possible to forward email messages from a single e-mail to numerous ones, if a number of people should be involved with the email communication.
