This feature will allow all mail sent to a domain to be forwarded to another domain. Adding a domain forwarder will override the default address for the selected domain.
To add a domain forwarder:
Note: Domain forwarding takes place only when a delivery is not successful. For example, a user sends an email to john@example1.com. If john@example1.com is an existing email address or auto responder, then the email will not be forwarded. The email will be forwarded if john@example1.com is not an existing email address or auto responder.
