我使用Ruby 2.0.0 MRI和Ubuntu的12.04 TLS VPS的Rails 3.2.12，并试图设置电子邮件通知我的应用程序。 这是工作的罚款前几天，但现在不是了。 我的虚拟主机是OVH。
我的SMTP设置：
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => 'sender@gmail.com',
:password => 'secret',
:authentication => 'plain',
:enable_starttls_auto => true
}
使用RAILS_ENV=production rails console ：
class MyMailer < ActionMailer::Base
def test_email
sender = "sender@gmail.com"
receiver = "receiver@example.com"
mail from: sender, to: receiver, subject: "Hello!", body: "World!!"
end
end
=> nil
MyMailer.test_email.deliver
输出：
Net::OpenTimeout: execution expired

我试过如下：
- 该
exception_notification宝石加入到设置在几天前。 我试图评论它的线Gemfile以及与其相配套的配置，并运行bundle install。 重新启动服务器后，问题仍然存在，即使我删除并重新创建宝石。 - 测试它在虚拟机上（完全相同的设置作为VPS包括iptables规则）： 作品
- 禁用iptables规则： 不工作
- 使用OpenSSL的从VPS手动连接到Gmail： 作品 （所以这不是一个防火墙的问题-在这里看到： 通过命令行连接到smtp.gmail.com ）;
- 启用Gmail帐户的选项IMAP（它被禁用）： 不工作
- 使用不同的Gmail帐户： 不工作
- 由红宝石1.9.3更换红宝石2.0.0
- 升级到Rails 3.2.13
是否有人有一个可能的线索，如何解决这个问题？
谢谢！
