Hope this helps http://www.isaserver.org/shinder/tutorials/publishing_a_mail_Server_with _isa_server.htm The exchange server must not have the firewall client installed. It must be configured as a secure nat client.

We have a NT 4.0 with SVPK 6.0 running MS Exchange Server 5.5. We have a W2000 SVPK 2 running ISA SERVER. I did the configuration to exchange email thru the ISA Server (all configuration needs was did). The problem is that we can send email using ISA Server but we can't receive email from ISA. I'm not sure if the problem is at the ISA or W2000 DNS (I did some tests with our DNS and it appears is ok), or Exchage Server Configuration. Anybody have any idea what can be happing? Anybody knows where I can find any paper or other kind of information that can help us? I waiting hear anything about that!
