Hi Qusai, It was one of the articles that discussed configuring the ISA firewall as a filtering SMTP relay. There are two of them, but I don't recall which one. The key is to install an SMTP relay on the ISA firewall, then configure remote domains on the SMTP relay for domains under your administrative control. Then for each remote domain, configure a different Smart Host to forward to. This allows a single IP address on the external interface of the ISA firewall to accept mail for multiple SMTP servers on the internal network. HTH, Tom -----Original Message----- From: Qusai A.

Make sure the new Exch server is SecureNAT to the ISA or much pain will ensue...
