带有gmail smtp的Rails 4邮件程序

Question

我想在我设置的开发文件中使用Rails 4的Mailer 4和Gmail的smtp配置：

  config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      :address              => "smtp.gmail.com",
      :port                 => 587,
      :domain               => "gmail.com",
      :user_name            => "mymail@gmail.com",
      :password             => "mygmailpassword",
      :authentication       => :plain,
      :enable_starttls_auto => true
  }

但我没有收到任何邮件。这是终端的输出：

To: antonioni.giovanni9@gmail.com
Message-ID: <55ffb56da9e91_aa929362303435c@pc-rails.mail>
Subject: Conferma ordine
Mime-Version: 1.0
Content-Type: multipart/alternative;
 boundary="--==_mimepart_55ffb56da807b_aa92936230342e1";

Content-Transfer-Encoding: 7bit


----==_mimepart_55ffb56da807b_aa92936230342e1
Content-Type: text/plain;
 charset=UTF-8
Content-Transfer-Encoding: quoted-printable

因此，我的应用程序试图发送电子邮件，但这没有出现在我的gmail仪表板上。有解决这个麻烦的办法吗？

Gmail服务需要一个应用程序密码才能从gmail帐户发送邮件(更多信息请访问此链接)。生成密码后，必须更改开发文件的配置：

  config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      :address              => "smtp.gmail.com",
      :port                 => 587,
      :domain               => "gmail.com",
      :user_name            => "mymail@gmail.com",
      :password             => "GENERATEDPASSWORD",
      :authentication       => :plain,
      :enable_starttls_auto => true
  }

然后重新启动服务器。为了捕捉我设置的错误：config.action_mailer.raise_delivery_errors = true (感谢Dipak的提示)
