You can set a number of specific mail forwarding options, as email sent to an alias email address (e.g. webmaster@yourname.com, sales@yourname.com, etc.), email will be forwarded to a preset POP mailbox that may be associatedd with your domain, external email address or even web mail address.
Unlimited Email Forwarding:
By default, all mail sent to alias addresses associated with your domain name (e.g. webmaster@yourname.com, sales@yourname.com, etc.), but not specifically forwarded; will be automatically forwarded to the email address that was provided when your account was set up. This email address is called the "default" mail forwarding address. This address can be changed in Email Settings within an ease-to-use web based Control Panel.
