By default, mail isn’t sent while in development. Instead, ActionMailer uses a sort of “test mode” where the email appears in the development log. We would need another email handler. I’m sure there are gems available to handle this very issue. I’ll look into it, but in the meantime I will go ahead and remove the production config from development.rb
