<p>How can I test sending email from my application without flooding my inbox? </p>

<p>Is there a way to tell IIS/ASP.NET how to deliver email to a local folder for inspection?</p>

Yes there is a way.
You can alter web.config like this so
  that when you send email it will
  instead be created as an .EML file in
  c:\LocalDir.
```
```
<configuration>  
     <system.net>    
      <mailSettings>      
       <smtp deliveryMethod="SpecifiedPickupDirectory">        
        <specifiedPickupDirectory pickupDirectoryLocation="c:\LocalDir"/>      
       </smtp>    
      </mailSettings>  
     </system.net>
    </configuration>
```
```
You can also create an instance of the
```
SmtpClient
```
class with these same settings, if you don't want to/can't change the web.config.  In C# that looks something like this:
```
```
var smtpClient = new SmtpClient();
smtpClient.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
var emailPickupDirectory = HostingEnvironment.MapPath("~/EmailPickup");
if (!Directory.Exists(emailPickupDirectory)) { 
    Directory.CreateDirectory(emailPickupDirectory)
}
smtpClient.PickupDirectoryLocation = emailPickupDirectory;
```
```
