Restricting Access to Address Book and Sending
Functions
3JX3-07H
Some cases of information leakage can be prevented by limiting the available fax and e-mail destinations to those
registered in the Address Book or LDAP servers, or by setting a PIN for the Address Book so that unauthorized users
cannot add or edit Address Book entries. You can also avoid sending documents to unintended recipients if the
machine is set to ask you to enter the fax number twice for confirmation.
