Hello everyone.

I just a beginner for ISA and MS product, I try to setup in test
environment with exchange 5.5 and ISA 2000 on W2K as following:

    Router -------------ISA Server----------+-----Lan (10.0.0.xxx)
xxx.xx5.6.225       xxx.xx5.6.251 (Ext.)    |
                    10.0.0.1 (Int.)         |
                                            |
                                        Exchange Serv. (10.0.0.250)

After setup clients can browse outside web and can send mail ,but cann't
receive mail from the outside, I try to check from the outside with
Email-Validation from www.network-tools.com the result is fail the error
message say about the email address has been rejected by ISA

I have no idea about DNS setting up that I think that is a problem in this
case.

I will apreciate if anyone give me the idea or the example of DNS setup
for local and where I should put DNS (I used ISP's DNS at External IP in
ISA server).

Best Regards, and thank you inadvance.

PS. - My Exchange Server is a DC.
    - My ISA is not a member in domain and no Active directory
