In cPanel, email accounts which forward to another address are known as forwarders.

How to create a forwarder in your cPanel interface:

Log into your cPanel interface via a web browser.

Once logged in, click on “Mail.” then you will be taken to the Mail Manager Main Menu.

In the new screen, click on “Forwarders” and then again on the "Add Forwarder" link.

In the "name" field, enter the address which you wish to forward elsewhere. For example, enter "sales" to forward emails sent to "sales@yourdomain.com" to another address.

You can enter names for which a POP account already exists and in that case, emails sent to it will be stored in the POP account and forwarded to the address of your choice. You can also forward emails to multiple addresses by listing them in the forwarding address field, separated by a comma. (address1,address2)

In the "forwarding address" field, enter the address to which you wish to forward emails. This address can be an account on the same server (for example sales@yourdomain.com forwarding to support@yourdomain.com), or it can be on a different server (your ISP, AOL, a different domain, etc).

Some people prefer to add multiple address by simply repeating the process of creating a forwarder, using the same name every time, but a different forwarding address.

Finally, click the "Add Forwarder" button. Your forwarding account has been created.
