title: Dummy SMTP server for development purposes
body: <p>I've been using a dummy smtp server called DevNull SMTP so that I can test my app which sends out notification emails.  It has a nice simple GUI, very helpful, but can't be scripted easily.  I can't even start it listening to port 25.  I have to run the app and then click on the start button...</p>
  
  <p>Is there a similar app that can be scripted easily?  Scripted in the sense that I can control it from a bash script or windows batch file and possibly even query the emails from my unit/functional tests.</p>
