Hi folks. I've got about 120 users on my network with email being done on a FC5 system using a combination of exim and dovecot. Email address -> mailserver user conversion is done through /etc/aliases. I'm looking at options to provide a corporate email address book that can be maintained on the mail server and used by the users using Outlook and Outlook express. Anyone got any ideas how best to do this, preferrably with pointers on how to set it up.
