當我嘗試通過Sorcery使用激活時，爲什麼Rails 3 Action Mailer不會發送電子郵件？

我使用巫術來激活電子郵件，並且我遵循他們的wiki教程：https://github.com/NoamB/sorcery/wiki/User-Activation。我很確定問題在於發送電子郵件，而不是如此激活，因爲這是另一個問題。當我嘗試通過Sorcery使用激活時，爲什麼Rails 3 Action Mailer不會發送電子郵件？

下面是用戶梅勒代碼：

class UserMailer < ActionMailer::Base 
    default :from => "[email protected]" 

    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

這是我的development.rb文件：

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   => "[email protected]", 
     :password    => "my_pw" 
    }

我得到這個，當我通過控制檯運行代碼：

編輯：這是電子郵件模板吃了：

什麼是模板是什麼樣子？ –

@Dave Newton我甚至不確定它是什麼意思，當它指的是模板。 – Tony

電子郵件內容有一個模板，對嗎？ –

我沒有得到任何錯誤，但郵件不出去。看着你的域名，我很想改變我的。我也在開發模式。我將其更改爲localhost：3000，郵件現在正在通過。

你們搖滾!!!
