Our exchange 2000 mail server is in LAN, SMTP gateway/IIS5.0 is in DMZ behind the Cisco Firewall/PIX525

The Excahnge 2000 server is sending out the NDR notice to sender, but sender never receive the NDR notice (the exchange server will issue a NDR to sender, if the recipient is an invalid email address). I found that the NDR messages have been moved to \inetpub\mailroot\badmail all the time, is this related to any configuration in the PIX or related to SMTP setting inIIS5? IS there any solution for this issue?

Messages sit in the badmail folder if they cannot be delivered.  Are you sure the recipients of the NDRs are also valid?  A lot of times, spammers will send email both FROM and TO bogus addresses.  So, when your mail server tries to send an NDR back to the bogus FROM address, it can't because it's bogus.  The NDR sits in badmail.

Yes, I tested it with my vaild hotmail and earthlink smtp mail account, the valid path and vaild recipient are in the copy of smtp header.

By default, the local server as a default domain in the domain section of smtp virtual server of iis, I add the my_corp.com as a remote domain. Should I need to change it as " *.com "? It seems that the NDR is unabled to get authention/validation.

Check the following:

Global Settings > Internet Message Formats > right click Default (or whatever) and select Properties > Click the Advanced Tab >

is the box for "Allow Non Delivery Reports" checked?
