僅生產中的郵件錯誤

[英]mailer error in production only

設置:VPS和Ubuntu 12.04,Apache,PhusionPassenger,Rail 3.2.12,Postgresql

我想通過我的應用發送確認郵件。 在開發模式下,一切正常,用戶收到一封郵件,但在生產環境中,出現此錯誤(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,錯誤應該在newsletters_controller.rb中(第45行已標記):

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

同樣,它僅在開發中有效,而在生產中無效。 我也嘗試將數據庫更改為Mysql2,但是發生相同的錯誤。

我的database.yml:

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

對於郵件,我將smtp與山man或gmail一起使用。 Gmail設置可以在另一個應用程序中正常運行...

我的環境

# 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:我發現提交保存在我的索引中。 所以我想數據庫可以工作。

有什么建議嗎? 謝謝

我通過從山rill改成新的密碼(API密鑰)解決了我的問題。 仍然不知道問題出在哪里,因為使用舊版本可以在開發模式下工作...

工作設置:

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'
  }
