Announcing mails_viewer - easiest way to test mails in Rails app (opens in new tab)

  python -m smtpd -n -c DebuggingServer localhost:25

Edit: you need root permission to listen on port 25. Otherwise you can use a different port > 1024.

1. I don't want to send out emails in dev mode. At all. (mailsafe) 2. I want an easier way of looking at the emails my server does send out (letter_opener, mailcatcher, mails_viewer) 3. I want to be able to preview an email without having to do the action that triggers it (mail_view)

I usually do this with a dummy controller rigged up to show them in the browser and fire them at whitelisted test inboxes, but always nice to see more ways people handle these challenges.

I think it would be better if you also put the screenshot in your blog into the README.md.
