cPanel email offers two options for email forwarding:
Forwarders send a copy of every email received at an address to another address. For example, setting up a Forwarder for [email protected], forwarding to [email protected], Jane will receive a copy of every message sent to John.
Forwarders in cPanel work even if the forwarding email address doesn't exist. In the example above, even if [email protected] didn't exist as its own email account, [email protected] would still receive emails sent to John.
Forward All Email for a Domain forwards any email sent to a domain name to the same email address at another domain name. For example, if you forward all email for coolexample.com to coolexample.net, all email sent to [email protected] gets forwarded to [email protected]. For more information, see cPanel's documentation.
If you Forward All Email for a Domain, that domain's email addresses do not receive email.
