SMTP/IIS5 : NDR is dropping to \inetpub\mailroot\badmail
Posted on 2004-04-01
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?
