Hi Brajesh, Yes, its possible. You can install the SMTP Message Screener on the ISA firewall and it will apply the filters you configure for both inbound and outbound mail. The key is to configure the relay configuration to make sure that it is not open, and that only the appropriate machines and perform outbound relay, and only the appropriate domains are allowed for inbound relay. I've doc'd the procedure in details for ISA 2004, and I think I may have doc'd it in ISA 2000 in the ISA Server 2000 Exchange 2000/2003 Deployment Kit, which you can find on the ISAserver.org Web site.
