I've correctly configured a Microsoft SMTP server for IIS 5.0, but the mail stays in the Queue folder and isn't delivered. The error message an internal DNS error caused a failure to find the remote server is appearing in Event Viewer. All the NTFS permissions are correct, and I've configured the SMTP service to use the correct NIC. When I use Telnet to access port 25 on the SMTP server, the server responds, so I know the SMTP service is working. I'm not using a smart host, and I can ping the DNS server as well as use the Microsoft Windows 2000 Resource Kit's nslookup.exe tool to resolve the domain names for the mail. Why isn't the server delivering mail?

Anyone have any suggestions where I might look to solve this problem?

Not sure if this will help or not

Could just be reverse DNS ... but i'm no expert.

Thank you ......... it did not solve the problem

Can you post some of the log file?

In order for cdonts to function the web site application needs to be set to low protection (runs in process). But why not use cdosys which can run with medium protection!

Theoretically it can be done with medium protection if the correct permissions can be set onto mailroot. Before cdosys I spent quite a bit of frustration trying to get those right.

Just give the IUSR and IWAM user permission. That should allow you to run it out of process.
