Forwarding Mail In CPanel And Not Keeping It At The Original Account

I'd like to create a forwarding address, and not have the original account keep the mail - but without having to delete the original account, since I'd like to keep my existing emails.

For instance if the old account is apples@domain.com, I'd like to forward new emails to oranges@new.com, where apples doesn't keep the new emails. Currently in cPanel when I create a forwarder apples@domain.com=>oranges@new.com, new emails are sent to both accounts.
