What is a forwarding address?
A forwarding addresses delivers email to some other email address. You can deliver mail to an account that you have with another service such as Yahoo or Gmail. You can also use forwarding aliases to deliver copies of mail to multiple recipients, so that mail to sales@yourdomain.com (for example) goes to all members of your sales team. If your employees already have email accounts elsewhere, you can use forwarding addresses instead of purchasing additional user accounts.
