While I agree with exchange 2k being very good compared with 5.x, check your systems. It seems MS decided that the no open relay thing was a bug, if you install SP3 it will turn you back into an open relay untill you explicetly close it.Quote:

Microsoft exchange has come a long way since version 5 for instance it is no longer an open relay by default. (w00t). it offers shared phonebooks, messaging service, IM, shared appointment calander, directory services and much more. It requires 2000 server (which you have), active directory, DNS (which you also have) and the knowledge to manage them. Its not a walk in the park if you don’t know what your doing. Its also pretty expensive as is the virus software that works with it.
