An access name may have many e-mail names. Generally, an access account user can check mail for anyone anywhere in the world assuming the access user has the mail name and password. Access passwords and e-mail passwords may be the same or different. To protect the rest of the world from SPAM, most operators of mail servers will not relay a message unless the identify of the sender is known. Operators who permit SPAM may find that everyone else in the world will block all mail from their site, SPAM or not.
Identity is known only to the operator of the access server.
