When I forward an incoming email to other email accounts, be it yahoo, hotmail, or gmail, I list all recipient email addresses in "cc" and "bcc". But the recipient not only can see the forwarded email but can also see other email addresses as well. How can I prevent the recipient to see other email addresses other than the email address of himself or herself? In other words, how can the recipient only see his or her email without any other email addresses disclosed as if he or she is the only recipient?
