The "Aliases" function allows you to view all your Alias accounts and associated "forward to" email addresses.
Alias accounts are email accounts that do not have a physical mailbox and must be forwarded to a regular existing account.
To view the email account(s) your Alias account is forwarded to, select the Alias account from the "Alias Accounts" list. The "forward to" account(s) will be displayed in the "Forward To" textbox.
