Is your NAVGW machine have a public or private IP Address? If it is a private IP address, where SMTP traffic will flow through the ISA server first, this is what I have configured: Create a server publishing mail wizard rule for SMTP Inbound. The external address is the ISA address, the internal address is your NAVGW machine. In this setup our A host record is the external address for our ISA server.
