My suggestion is as follows: Manually test by configuring an email client (any client) in such a way as to violate the rules you have written. Then try to send email to an account you control on another server (I use my hotmail account for this). If it relays, then you know you made a mistake so

ISA's not a bad product. That being said, it is not the end-all-and-be-all of security solutions either. If security is important, you can run a filtering router behind your ISA server (on a non-MS OS for added defence in depth) and this is what I would do. You could use a Cisco solution, a

First of all, I agree that RPC is wonderfully extensible and that has been a strong benefit of the NFS architecture, when combined with NIS, etc. My own preference however, is to begin substituting AFS for NFS where possible. It is more scalable, more secure, and easier to access from a user pers
