hey friends, I am using postfix on Centos4.0 as mailserver. I am looking for a global address book solution means every email client in my network whether outlook, outlookexpress, thunderbird, kmail, evolution etc. can find the user's email ids from that address book. LDAP has such feature but I am not able to find any good howto or Is there any other solution ? Please let me know if you need any further inputs. Thanks & Regards Ankush Grover
