I am building a server for my company. The hardware consists of dual opteron quad core processors, 8 gigs of ram, 3 one terabyte drives, dual gigabit Ethernet interfaces. Our connection is 20 megs down 6 megs up. I want a web server and mail server to host 3 or 4 customers (20 to 50 e-mail accounts each) to start with plus a file server for internal company use. What would be the recommended software configuration and which howtos to use. Many thanks in advance for any help and guidance.
For the file server you could use this setup: http://www.howtoforge.com/debian-lenny-standalone-server-with-tdbsam-backend For the rest, try this: http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-courier-ispconfig-3
