Question

设置：VPS与Ubuntu 12.04，Apache，PhusionPassenger，Rail 3.2.12，Postgresql

我想用我的应用发送确认邮件。在开发模式下一切正常，用户收到邮件但在生产中我收到此错误（日志）：

Started POST "/newsletters" for 1XX.16X.30.XX at 2013-02-26 09:22:47 +0000
Processing by NewslettersController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"XXXXXXXXXXXXX=",
"newsletter"=>{"name"=>"Test", "email"=>"test@example.com"}, "commit"=>"Submit"}

  Rendered newsletter_mailer/confirmation.text.erb (0.4ms)

Sent mail to test@example.com (44ms)
Completed 500 Internal Server Error in 134ms

Errno::ECONNREFUSED (Connection refused - connect(2)):
  app/controllers/newsletters_controller.rb:45:in `create'

所以我想，错误应该在newsletters_controller.rb中（标记为第45行）：

def create
    @newsletter = Newsletter.new(params[:newsletter])

    if @newsletter.save
      NewsletterMailer.confirmation(@newsletter.email).deliver ### line 45
      flash[:success] = 'It works!'
      redirect_to root_path
    else
      flash[:error] = 'Error!'
      render action: "new"
    end
end

NewsletterMailer.rb

class NewsletterMailer < ActionMailer::Base
  default from: "some@email.com"

  def confirmation(email)
    mail to: email,
         subject: "Welcome"
  end
end

同样，它仅适用于开发但不适用于生产。我也尝试将数据库更改为Mysql2但发生了同样的错误。

我的database.yml：

production:
  adapter: postgresql
  encoding: unicode
  reconnect: false
  database: app_production
  pool: 5
  username: user
  password: secret
  host: localhost

对于邮件我使用带有mandrill或gmail的smtp。 Gmail设置在其他应用中运行良好...

我的环境.rb

# Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
LandingPage::Application.initialize!

LandingPage::Application.configure do 
  config.action_mailer.delivery_method = :smtp

  config.action_mailer.smtp_settings = {
    :address   => "smtp.mandrillapp.com",
    :port      => 587, # or 25
    :enable_starttls_auto => true, # detects and uses STARTTLS
    :user_name => "user",
    :password  => "password",
    :authentication => 'login' # Mandrill supports 'plain' or 'login'
}
end

更新：我发现提交的内容会保存在我的索引中。所以我猜数据库可以工作。

有什么建议吗？感谢

我通过从mandrill更改新的密码（api-key）解决了我的问题。仍然不知道问题是什么，因为旧的问题在开发模式下工作......

工作环境：

YourApp::Application.configure do
  config.action_mailer.smtp_settings = {
    :address   => "smtp.mandrillapp.com",
    :port      => 587,
    :enable_starttls_auto => true,
    :user_name => "MANDRILL_USERNAME",
    :password  => "MANDRILL_PASSWORD", # SMTP password is any valid API key
    :authentication => 'login'
  }

仅限生产中的邮件错误
