Hi every one We are planning to start ISP with basic service like Mailing,CHAT,NEWS and WEB based on Linux Redhat 6.1 . We have decided to go for Qmail Mailing system. Our setup will have 5 centres (Initially) and each centre will have a minimum of 25,000 users and can grow up to 1,00,000 users. ( not concurrent ) . We need information on scalling in terms of Hardware. What is the hardware recommended? What storage solution is recoommended? Is it a good idea to link qmail with LDAP ? if so what LDAP? (We came to know that OpenLDAP can handle 50 requests per sec , We require Powerful LDAP) Please suggest us regarding the above Thanks in advance N.Saravanan Unix System Administrator DSQ Software Limited Nandhanam Chennai 600 035
