ruby-on-rails – 无法使用gmail stmp服务器发送邮件(在话语中)

我昨天注册了一个新的Gmail帐户,我可以登录浏览器和电子邮件客户端软件.

然后我在config / environments / production.rb文件中配置话语：

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  :address   => "smtp.gmail.com",:port      => "587",:user_name => "smtp4shuzu@gmail.com",:password  => "12345678",:authentication => :plain,:domain => "shuzhu.org",:enable_starttls_auto => true
}

启动用于在后台发送邮件的sidekiq：

nohup bundle exec sidekiq > log/sidekiq.log 2>&1 &

然后在生产模式中开始讨论：

rails server -e production -d

但它不起作用.我可以在sidekiq.log中看到一些错误：

2013-03-01T03:06:02Z 30687 TID-qib28 WARN: {“retry”=>true,“queue”=>”default”,“class”=>”Jobs::UserEmail”,“args”=>[{“type”=>”signup”,“user_id”=>42,“email_token”=>”b40a21ece2b14586e346abfd96685975”,“current_site_id”=>”default”}],“jid”=>”558bb6bd5aa36cfc8d3d1e91”,“error_message”=>”Connection refused – connect(2)”,“error_class”=>”Errno::ECONNREFUSED”,“failed_at”=>2013-03-01 03:06:02 UTC,“retry_count”=>0}

/home/discourse/.rvm/rubies/ruby-1.9.3-p385/lib/ruby/1.9.1/net/smtp.rb:540:in `tcp_socket’

我尝试过各种smtp设置,但没有一个能够正常工作.

更新：

Per @ Basil的答案,我刚试过：

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  :address   => "smtp.gmail.com",:port      => 587,:user_name => "smtp4shuzu",:authentication => "plain",:enable_starttls_auto => true
}

但它有同样的错误.域shuzu.org是我的网站的域名,我在想我应该将它传递给smtp.现在我删除了它,但仍然无法正常工作.
