ActionMailer不在Rails 3.1.1中发送邮件

Question

当我的工作人员尝试发送电子邮件时,我在ActionMailer中收到错误

Errno::ECONNREFUSED
    Connection refused - connect(2)

我在初始化程序中有一个文件setup_mail.rb,它具有smtp设置

 ActionMailer::Base.smtp_settings = {
 address: "smtp.gmail.com",
 port: 587,
 domain: 'betterlabs.net',  
 user_name: 'policemerepiche@gmail.com',
 password:
 authentication: 'plain',
 enable_starttls_auto: true
 }

和我的邮件方法

   def send_email(email)
begin
# attachments['result.csv'] = File.read(file)
 mail(to: "bhushanlodha@gmail.com", subject: "hey")
 puts "====Mail Sent===="
 rescue Exception=>e
 puts e.inspect
 end
end

development.rb

  config.action_mailer.delivery_method = :smtp

什么可能出错？谢谢.

我有同样的问题,如果从Web进程或Rails控制台执行,我的邮件程序将正确地发送电子邮件,但如果它们排队等待在工作进程中传递,则会引发Errno :: ECONNREFUSED异常.

我也使用初始化程序来设置配置.关于它的一切都闻起来有点像某些方式遗漏了SMTP设置,但只有在由工作进程运行时.

最后我把它添加到邮件中:

m = mail(to: "herpderp@example.com", subject: "Example")
puts m.to_yaml
return m

这表明邮件实例中有一个smtp设置对象(或从其中引用,并包含在to_yaml中),这个smtp设置对象没有我在初始化程序中声明的smtp设置.这是一段摘录:

settings:
  :address: localhost
  :port: 25
  :domain: localhost.localdomain
  :user_name: 
  :password: 
  :authentication: 
  :enable_starttls_auto: true
  :openssl_verify_mode: 
  :ssl: 
  :tls: 

显然这是不正确的.此外,从同一声明中打印Rails.application.config.action_mailer.smtp_settings正在打印正确的设置.

因此,为了缩小可能性,我当然将我的设置声明移回了development.rb,下次将这些设置打印在我的worker stdout上时,它们是正确的,并且电子邮件按预期传送.

所以我不能说我完全理解如何/何时处理初始化程序中设置的配置,因为我对Rails核心模块的深度没有那么多的可见性,但我可以说在那里的某个地方,由于如何邮件实例从全局配置中检索smtp设置,它们在初始化程序中声明的时间与环境文件之间存在差异.

课程为我学到了.使用初始化程序类不要超出标准的Rails配置标准.一旦我将配置移回development.rb,一切都按预期工作.也许在那里的其他人可以帮助解释环境rb文件和初始化器之间发生的事情.
