title: Ruby on Rails: How to Configure the Devise Mailer?
body: <p>I have made an application on Ruby on Rails. I'm using Devise and I need to use the recoverable password feature.
  I found these configurations on development.rb:</p>
  
  <pre><code>config.action_mailer.default_url_options = { :host =&gt; 'localhost:3000' }
  
    config.action_mailer.delivery_method = :smtp
    config.action_mailer.perform_deliveries = true
    config.action_mailer.raise_delivery_errors = false
    config.action_mailer.default :charset =&gt; "utf-8"
  
    config.action_mailer.smtp_settings = {
      address: "smtp.gmail.com",
      port: 2525,
      domain: "gmail.com",
      authentication: "plain",
      enable_starttls_auto: true,
      user_name: "MY_EMAIL",
      password: "MY_PASS"
    }
  </code></pre>
  
  <p>When I test it, it looks okay, It doesn't throw any exception on the application, but the email never comes. Please, how can I configure this?</p>
