My company has one Exch 2000 server(SvrEx2K) which located in private LAN and has one internal IP.
I try to relay outgoing email though a smart host.
So, I setup a “IIS SMTP service” in ISA server(SvrFW). And let this ISA server to be a smart host.
Until now, I can receive incoming mail from internet, but outgoing. All of outbound mail always queue in smart host.
I am sure the External NIC of ISA server was the first order of network connections.
I got a lot error messages like as below..===============================================
