Can you tell us how you tried to set up the port filtering on this server? Did you configure it by TCP, UDP or IP Protocol? Also, remember that internally, if your clients are connecting via Outlook, they will be using different ports. Do you have 2 NIC's in this server? More info on your exact setup please. Ports 25, 80 and 110 sound like the ports you want open to the outside world. Inside, I wouldn't restrict ports. It would get really messy.

Thanks for the reply.
Not for relay, but we do not have any firewall as yet, and i would like to close unecessary ports. Its a fresh installtion NT server PDC, Exchange 5.5. So all the ports are open. I just want 25, 110, 80 to be open.
I tried that on TCP/IP security and nobody could connect to mail server ....
