Testing emails can sometimes be a bit challenging. smtp4dev is a small program that intercepts all received emails so you can quickly send and view emails from any application that uses it as the SMTP server.
For a .NET application just add this to the config file.
<mailSettings>
<smtp>
<network host="localhost"/>
</smtp>
</mailSettings>
Now all emails that the application sends will appear for your viewing pleasure in the email list (pictured below).
