Hi. A book that covers both the OS and the services into real detail would be like a a few thousand pages - there is no such thing. For DNS, you need the Cricket Book (DNS and BIND), for other services you need other books. However, a combination of the FreeBSD handbook and the usually excellent man pages takes you a long way! For the mail server, if you need connectivity from outside, yes, you need to expose it, if not, mail can just be routed to the insisde. Properly set up there should not be a problem exposing it though - most mail servers are built to do just that. As the administrator it's your obligation to keep the stuff updated so that any security holes are fixed before too late. Just my SEK0.02 Per olof
