title: ActionMailer and development mode, can it write to a file or something?
body: <p>I want to test my registration process locally (development mode), how can I test how emails will be sent out and rendered etc?</p>
  
  <p>I am not referring to a unit-test or integration test, but just while developing my app and going on the register page etc. I want it to send out the emails but to a file not using smtp.</p>
  
  <p>Is this possible?</p>
  
  <p>What options do I have?</p>
