错误

我已经设置了ActionMailer并在开发中完美运行。我可以致电UserMailer.welcome(user).deliver，电子邮件到达目的地。但是，当我将代码推送到生产环境并调用相同的deliver方法时，突然出现错误：

Errno::ECONNREFUSED: Connection refused - connect(2)

迄今为止的问题

我可以提供的最有价值的信息可能是Message对象上的实际delivery_method数据在生产中不正确。在开发中，当我调用UserMailer.welcome(user).delivery_method时，（格式化）输出为：

#<Mail::SMTP:0x000001042c4a20 @settings={
  :address=>"smtp.gmail.com",
  :port=>587,
  :domain=>"foobar.com",
  :user_name=>"example@foobar.com",
  :password=>"MY_PASSWORD",
  :authentication=>"plain",
  :enable_starttls_auto=>true,
  :openssl_verify_mode=>nil}>

这明显与我在mailers.yml中定义的设置相匹配。在制作中，当我进行相同的调用时，输出为：

#<Mail::SMTP:0xbfb2c18 @settings={
  :address=>"localhost",
  :port=>25,
  :domain=>"localhost.localdomain",
  :user_name=>nil,
  :password=>nil,
  :authentication=>nil,
  :enable_starttls_auto=>true,
  :openssl_verify_mode=>nil}>

这似乎是line 22 of ActionMailer::DeliveryMethods上定义的默认值，而不是mailers.yml中我自己的设置。

相关代码

据我所知，我的环境应该让ActionMailer设置相同。

配置/ environment.rb中：

Myapp::Application.config.action_mailer.delivery_method = :smtp
Myapp::Application.config.action_mailer.smtp_settings = YAML.load_file(
    Rails.root.join('config', 'mailers.yml'))[Rails.env].to_options

配置/ mailers.yml：

default: &default
  address:              smtp.gmail.com
  port:                 587
  domain:               foobar.com
  user_name:            example@foobar.com
  password:             MY_PASSWORD
  authentication:       plain
  enable_starttls_auto: true

development:
  <<: *default

production:
  <<: *default

配置/环境/ development.rb：

Myapp::Application.configure do
  # ...
  config.action_mailer.raise_delivery_errors = false
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.interceptors = ['MailInterceptor']
  # ...
end

配置/环境/ production.rb：

Myapp::Application.configure do
  # ...
  config.action_mailer.default_url_options = { :host => 'foobar.com' }
  # ...
end

请注意，我还尝试在development.rb中注释掉两个额外的行（并尝试将它们添加到production.rb中），没有任何更改 - 我仍然在生产中遇到相同的错误，但没有开发。

此外，虽然我不认为它是相关的，但我将包括我在development.rb中引用的MailIntercepter（它只是将所有邮件重定向到我的电子邮件地址而不是测试用户的电子邮件地址）：

class MailInterceptor
  def self.delivering_email(message)
    message.subject = "[#{message.to}] #{message.subject}"
    message.to = "example+catcher@foobar.com"
  end
end

Answer 1

想出来，虽然它似乎违背了我认为应该是Rails 3.1配置的标准方法。

更改了这一行：

Myapp::Application.config.action_mailer.smtp_settings = YAML.load_file(
    Rails.root.join('config', 'mailers.yml'))[Rails.env].try(:to_options)

对此：

ActionMailer::Base.smtp_settings = YAML.load_file(
    Rails.root.join('config', 'mailers.yml'))[Rails.env].try(:to_options)

仍然不确定为什么前者在开发中工作而不是生产，但后者现在适用于我的生产，所以这就是我现在要用的。

Answer 2

您有environment.rb设置的可能性如下：

Myapp::Application.initialize!
Myapp::Application.configure do { }

如果是，请交换这两行。我有nearly the same issue（邮件程序配置在dev中工作，而不是在其他环境中），这就是问题所在。

ActionMailer设置在开发和生产之间错误地不同
