Sorceryを通じてアクティベーションを使用しようとしているときにRails 3のアクションメーラーがメールを送信しないのはなぜですか？

Question

私は電子メールを有効にするために魔法使いを使いました。私はwikiチュートリアルhttps://github.com/NoamB/sorcery/wiki/User-Activationに従ってきました。 私は、問題が別の問題であるため、電子メールを送信している間に問題があると確信しています。ここで

ユーザーメーラーのためのコードです：私はコンソールを介してコードを実行したとき、私はこれを取得してい

SampleApp::Application.configure do 
    # Settings specified here will take precedence over those in config/application.rb 

    config.action_mailer.delivery_method = :smtp 
    ActionMailer::Base.perform_deliveries = true 


ActionMailer::Base.smtp_settings    = { 
     :address    => "smtp.gmail.com", 
     :port     => "587", 
     :domain    => "localhost:3000", 
     :enable_starttls_auto => true, 
     :authentication  => "plain", 
     :user_name   => "my_gmail_account@gmail.com", 
     :password    => "my_pw" 
    } 

：

class UserMailer < ActionMailer::Base 
    default :from => "my_gmail_account@gmail.com" 

    def activation_needed_email(user) 
    @user = user 
    @url = "http://0.0.0.0:3000/users/#{user.activation_token}/activate" 

    mail :to => user.email, 
     :subject => "Welcome to PolyHerd.com" 
    end 
end 

ここに私のdevelopment.rbファイルです

メールは出ていませんでした。 あなたのドメインを見て、私は私のものを変えようと誘惑を受けました。開発モードでもあります。私はそれをlocalhost：3000に変更しました。そして、メールは現在通過しています。

あなたのロック！
