title: Automatically logging email sent through Rails
body: <p>We send out many emails through Rails (and then through Amazon SES). I'd like to now log all of those emails in our database so we know exactly which emails were sent where and all the details. I'd also love to know which class/method sent those emails or some way to tag them.</p>
  
  <p>This must be an extremely common need, so I'm curious if there's a mechanism with Rails to automatically handle this?</p>
