Using Visual Studio 2010; .NET 4.0, Windows 7 Professional, w/Service Pack 1. [32-bit OS]

I have the smtp set to localhost in the code with port 25.

In the Options tab, I have the Domain Name set to localhost, the ListenInterface set to, and the Port Number set to 25. 

Also, there is no Session log being written.

When my app tries to send an email I get following problem details:
