Ruby Mail gem:连接被拒绝 - connect(2) (Errno::ECONNREFUSED)

Question

我正在尝试使用 Ruby 进行简单的邮件投递 mail gem :

require 'mail'
Mail.deliver do
   from    'me@test.lindsaar.net'
   to      'varatis@gmail.com'
   subject 'Here is the image you wanted'
   body    File.read('body.txt')
end

但是我得到这个错误:

Users/varatis/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/net/smtp.rb:546:in `initialize': Connection refused - connect(2) (Errno::ECONNREFUSED)

我该如何解决这个问题？我假设这与 Mail 使用的默认端口有关。

Answer 1

好的，明白了。

Sendmail 没有运行，所以我启动了它，并更改了这些行:

require 'mail'
mail = Mail.new do
  from     'me@test.lindsaar.net'
  to       'varatis@yahoo.com'
  subject  'Here is the image you wanted'
  body     File.read('body.txt')
end

mail.delivery_method :sendmail

mail.deliver
