If you’ve ever written an application that sends out email you may have written the code and executed it numerous times to check that the logic works and that the email appears as you hope. This obviously means you have to hit your SMTP server each time, open your email client and check your emails each time.
Reading through my Twitter timeline I saw @TheCodeJunkie asking about the app that you can use to test sending emails from your application.
Intrigued, I kept an eye on my timeline and found that the application in question was Papercut
In simple terms you put Papercut on a machine (most likely your development machine) and in your code set the SMTP host to be the IP Address of where Papercut is running and fire up your application and watch Papercut notify you from the system tray that it’s recevied a message.
