连接被拒绝 - 连接(2)Ruby on Rails邮件设置

我在两者中设置了smtp设置,config/environments/production.rb并且development.rb我在`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/为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" 

我收到了错误 Connection refused - connect(2)

虽然我在localhost中使用以下配置工作,但我没有收到任何错误,并且邮件已经发送.

config/initializers/setup_mail.rb(localhost)

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,错误显示如下

调节器

def sendResume
@name =params[:name]
@email_id = params[:email_id]
@mob_no = params[:ph_no]

attachments = params[:resume]
if simple_captcha_valid?

 if params[:resume]
     filename=attachments.original_filename   

    extname = File.extname(filename)[1..-1]
    mime_type = Mime::Type.lookup_by_extension(extname)
    content_type = mime_type.to_s unless mime_type.nil?


        if content_type !="application/pdf"
           flash[:error]= "Only pdf files are allowed"
           redirect_to :action=>"careers"
        else
         File.open(Rails.root.join('tmp', 'uploads', attachments.original_filename), 'w') do |file|
          re = attachments.read
          file.write(re.force_encoding("utf-8"))
          @attached_path = file.path
        end


        begin
          ResumeMailer.sendResume(@name, @email_id, @mob_no, @attached_path, attachments.original_filename).deliver
          flash[:notice] = "Your resume has been submitted successfully"
          redirect_to :action=>"careers"
        rescue Exception => e
          puts e.message

          logger.warn "error sending mail"
          flash[:error]= "Error in submitting resume"
          redirect_to :action=>"careers"
        end

     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,但在图形模式下(在浏览器中)我收到错误Connection refused - connect(2).

怎么了,

提前致谢.
