The Problem: You have a brand new Windows 2008 server and you are testing your web application and trying to send an email. Every time you try to send an email via the web application you get the following error
“System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:25”
The Cause: SMTP services are not installed on the server, they do not seem to be installed by default.
The Solution: SMTP is not configured on the server. Go ahead and add in SMTP (it is not installed by default). It will take about 60 seconds to install. You will then get the error “Mailbox unavailable. The server response was: 5.7.1 Unable to relay for email@example.com”. You then must run on the SMTP relaying services via the IIS 6 interface (for some reason) in start/control panel/administrative tools/internet information services and add the current account from there.
