用户确认电子邮件不发送到生产中。 Rails，Heroku，Gmail

Question

我已经遍布谷歌和stackoverflow寻找答案，但一直无法找到任何解决方案。我正在尝试设置smtp电子邮件，以便在注册后进行用户确认。它在开发中工作正常。即使使用MailCatcher，它也会以某种方式绕过它并从我指定的Gmail发送到正确的电子邮件。

config.action_mailer.raise_deliver_errors = true
config.action_mailer.perform_deliveries = true
config.assets.raise_runtime_errors = false
config.assets.quiet = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
 :address        => "smtp.gmail.com",
 :enable_starttls_auto => true, 
 :domain => 'hieu-vo.herokuapp.com',
 :port           => 587 ,
 :user_name      => '[email protected]',
 :password       => 'xxxxxx',
 :authentication => 'plain',
 :openssl_verify_mode  => 'none' }
config.action_mailer.default_url_options = { host: 'hieu-vo.herokuapp.com' }

这是我使用heroku logs --tail时的日志

我想知道我的配置是否错误，但在我的本地机器上它仍然可以正常工作。因此它可能是heroku的用户问题。多谢！

我更喜欢使用mandrill app而不是gmail https://mandrillapp.com/login/?referrer=%2F

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      :address => "smtp.mandrillapp.com",
      :port => 587,
      :domain => 'www.xyz.com',
      :user_name => 'xyz',
      :password => 'xxx',
      :authentication => :plain,
      :enable_starttls_auto => true 
  }
