I plan on running zimbra in a school division with a 5000+ userbase. Because the users are students protection of the childs identity is a huge issue. Currently when you send an email from Zimbra the display name on the recievers end is the users full name. I need to be able to change this to display the email address instead and still keep the first name and last name in the LDAP description info. How can I go about changing this?
