All I am in need of some urgent help please. I have a windows 2000 server with exchange 2000 (both SP2). I have enabled the SMTP Virtual Server so that it does not relay. However, my ISP is telling me that it is still open. I have published the server through ISA 2000 SP1. Is ISA causing the problem by opening it up??? Once I have the relaying issue sorted, I need to install Norton for Gateways. Has anyone else had any problems with installing this. I have stopped all the exchange and SMTP services to make port 25 available when I install. However, after the install, I am unable to telnet to port 25. Your help would be much appreciated.
