title: Way to intercept emails on smtp docker (namshi/smtp)
body: <p>I am looking for a way to test the email sending feature of our app. I have configured namshi/smtp docker image to act as an smtp server and our app is using this smtp server to send emails. We currently have a system that reads the email on the client side once its delivered, to verify we are formatting the email correctly. This is a bit unreliable since it involves an actual email being delivered.</p>
  <p>So, I wanted to see if there is a way to intercept or read emails being delivered through this local smtp server. I checked the logs of the smtp server but as expected, it doesn't have any details of the email body or subject. Anyone knows anyway I could intercept these smtp requests somehow?</p>
  <p>Or if there is a better way to verify email formatting as part of integration testing?</p>
