title: A good, free, simple, non-"trial" local SMTP server for development?
body: <p>I'm running Windows Vista on my development machine... tried four SMTP servers so far (2 crashed, 2 turned out to be trial ware after being promoted as "free"). So I don't have IIS6 SMTP available.</p>
  
  <p>Do you know any simple, hassle-free SMTP server that I can use? I need absolutely no bells and whistles. All it needs to do is listen on port 25 and send off emails.</p>
  
  <p>Help?</p>
