ruby-on-rails - 连接被拒绝 - connect(2) Ruby on Rails 邮件设置

Question

我在 config/environments/production.rb 中都设置了 smtp 设置和 development.rb我还在`config/initializers/setup_mail.rb 中添加了设置

config.action_mailer.default_url_options = { :host => 'ipaddress' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  :address              => 'smtp.gmail.com',
  :port                 => 587,
  :domain               => 'gmail.com',
  :user_name            => 'EMAIL_ADDRESS@gmail.com',
  :password             => 'pass',
  :authentication       => :plain,
  :enable_starttls_auto => true,
  :openssl_verify_mode  => 'none'
}

配置/初始化程序/setup_mail.rb

ActionMailer::Base.smtp_settings = { 
  :address              => 'smtp.gmail.com',
  :port                 => 587,
  :domain               => 'gmail.com',
  :user_name            => 'EMAIL_ADDRESS@gmail.com',
  :password             => 'pass',
  :authentication       => :plain,
  :enable_starttls_auto => true,
  :openssl_verify_mode  => 'none'
} 

ActionMailer::Base.default_url_options[:host] = "ipaddress" 

我收到错误 Connection refused - connect(2)
当我使用以下配置在 localhost 中工作时，我没有收到任何错误，并且邮件也已发送。

配置/初始化程序/setup_mail.rb (本地主机)

ActionMailer::Base.smtp_settings = { 
  :address              => 'smtp.gmail.com',
  :port                 => 587,
  :domain               => 'localhost',
  :user_name            => 'EMAIL_ADDRESS@gmail.com',
  :password             => 'pass',
  :authentication       => 'plain',
  :enable_starttls_auto => true
} 

ActionMailer::Base.default_url_options[:host] = "localhost:3000" 

在控制台中运行时，错误如下所示，

     end
    else
      flash[:error]= "Please upload your resume"
      redirect_to :action=>"careers"
    end
else

  flash[:error]= "Incorrect captcha"
   redirect_to :action=>"careers"
end

end

安装后 postfix错误在控制台模式下消失，邮件从控制台发送，但在图形模式(在浏览器中)我收到错误 Connection refused - connect(2) .

怎么了，

提前致谢。

我看到您在两台服务器上尝试了相同的设置，但仅在您的生产/非本地主机环境中遇到问题。

这表明环境本身的网络配置存在问题。

在与应用程序相同的服务器上的命令行中，尝试以下命令

telnet smtp.gmail.com 587

您应该会看到如下所示的内容

telnet smtp.gmail.com 587
Trying 173.194.79.108...
Connected to gmail-smtp-msa.l.google.com.
Escape character is '^]'.
220 mx.google.com ESMTP dd5sm276863pbc.85 - gsmtp

如果您没有看到这一点，您很可能会收到连接错误。这意味着您的机器无权访问 gmail 服务器。可能的问题是 a) 一般出站网络连接，b) 防火墙专门阻止所有出站连接 c) 防火墙阻止/允许连接到特定端口或主机

如果这不起作用，请尝试以下端口代替 587

telnet smtp.gmail.com 465
telnet smtp.gmail.com 25

如果其中之一更成功，请相应地更改邮件服务器设置以使用。

编辑:我们在使用 Gmail 和使用自定义域的 Gmail 时遇到了很多麻烦。可以提供帮助的一件事是从配置文件中删除 :domain 行，尝试不使用它。

作为引用，这是我在 prod 中使用我们由 Gmail 托管的自定义域的 Gmail 配置:

config.action_mailer.default_url_options = { :host => "my.website.com" }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'website.com',
    user_name:            'user@website.com',
    password:             'password',
    authentication:       'plain',
    enable_starttls_auto: true
}

此外，如果您在 Gmail 帐户上启用了 2 因素身份验证，您可能需要禁用它并再次尝试以确认它不会使问题复杂化。
