Testing SharePoint outgoing email with Papercut

I found a very cool utility this week that has saved me some precious time.  I'm working on a SharePoint 2007 project running on Windows 2003 Server and I needed to adjust a feature of the application to send some confirmation emails.  My first inclination was to setup an SMTP server for testing.   As usual, I started with a search on Google and fortunately for me I accidentally stumbled across Papercut as an alternative to doing my email testing.  No need to setup an SMTP server.  No need to constantly jump into my email and check for the confirmation.  For those times when you do need to see the email in an email client (when you need to check HTML rendering) you can forward captured emails.
