I have a Windows Server 2008 box with IIS7. I have added the SMTP role/feature in Server Manager. I have an asp web page that sends mail from the server to 1 or 2 support addresses over the internet.
This worked fine on our 2003 box. We have upgraded to 2008 and now mail is stuck in the queue folder.
If I go into IIS 6.0 Manger I see that the SMTP Virtual Server is started. Any ideas?
