云控制Rails 3邮件

Question

问题:云控制服务器上的Errno::ECONNREFUSED (Connection refused - connect(2) for "localhost" port 25):。

环境smtp设置：

   config.action_mailer.smtp_settings = {
    address: "smtp.mandrillapp.com",
    port: 587,
    enable_starttls_auto: true, 
    user_name: ENV["MANDRILL_USER"],
    password: ENV["MANDRILL_PASSWORD"],
    authentication: 'login',
    domain: 'domain.example'
}

当在服务器上检查Project::Application.config.action_mailer.smtp_settings时，请接收以下内容，这是正确的：

{:address=>"smtp.mandrillapp.com", :port=>587, :enable_starttls_auto=>true, :user_name=>"correct_user", :password=>"correct_password", :authentication=>"login"}

但是由于上面提到的问题，猫还是不发电子邮件。Mailer以某种方式跳过此设置并使用:address=>"localhost"，如果我直接使用Net::SMTP并指示服务器控制台上的地址和端口，则可以正确地发送邮件：

Net::SMTP.start('smtp.mandrillapp.com', 587, 'some_domain', ENV["MANDRILL_USER"], ENV["MANDRILL_PASSWORD"], :login) do |smtp|
 smtp.send_message msgstr, 
 'user@mail.com',
 'user1@mail.com'
end

=> #<Net::SMTP::Response:0x007f1a6e763998 @status="250", @string="250 2.0.0 Ok: queued as B768D480191\n">

有人能帮助在cloudcontrol上设置smtp设置吗？还是我错过了一些关于云层控制平台的东西？

它实际上是临时服务器..。

Project::Application.configure do

 config.cache_classes = true
 config.action_controller.default_url_options = {:host => "staging_server_host"}
 config.action_mailer.default_url_options = {:host => 'staging_server_host'}
 config.consider_all_requests_local = false

 config.action_controller.perform_caching = true
 config.serve_static_assets = false
 config.action_mailer.delivery_method = :smtp

 config.action_mailer.perform_deliveries = true
 config.assets.compress = true
 config.assets.compile = true

 config.assets.digest = true
 config.log_level = :debug
 config.action_controller.asset_host = "staging_server_host"

 config.action_mailer.raise_delivery_errors = true
 config.i18n.fallbacks = true
 config.active_support.deprecation = :notify

 config.after_initialize do
   config.action_mailer.smtp_settings = {
       address: "smtp.mandrillapp.com",
       port: 587, # ports 587 and 2525 are also supported with STARTTLS
       enable_starttls_auto: true, # detects and uses STARTTLS
       user_name: ENV["MANDRILL_USER"],
       password: ENV["MANDRILL_PASSWORD"], # SMTP password is any valid mandrill API key
       authentication: 'login', # Mandrill supports 'plain' or 'login'
       domain: 'cloudcontrolapp.com', # your domain to identify your server when connecting
   }
 end
end

编辑:这是我在服务器上找到的Procfile：

web: bundle exec thin start -R config.ru -e $RAILS_ENV -p $PORT
rake: bundle exec rake
worker: bundle exec rake jobs:work
console: bundle exec rails console

Answer 1

问题就在staging.rb中：

config.after_initialize do
  #adding smtp settings in this block was invisible (or too late) for staging.rb
end

它可能会帮助那些不熟悉rails初始化过程的人。我不是真的：)

Answer 2

对于其他遇到这个问题的人来说，Sergii的诊断是正确的，但是有一个解决办法。在将smtp_settings设置在config.action_mailer上之后，将它们复制到ActionMailer::Base.smtp_settings：

ActionMailer::Base.smtp_settings = config.action_mailer.smtp_settings
