Action Mailer does not send mails at all

Rails 3.1.3

I have followed the RailsCast ActionMailer.

Around 5minutes, Ryan succeeds in sending mails, but I don't.

My setup_mail.rb

ActionMailer::Base.smtp_settings = {   :address => "smtp.gmail.com",   :port => 587,   :domain => "gmail.com",   :user_name => "soujiro0725@gmail.com",   :password => "xxx",   :authentication => "plain",   :enable_starttls_auto => true }

I added to users_controller.rb

        UserMailer.registration_confirmation(@user).deliver

and user_mailer.rb

class UserMailer < ActionMailer::Base   default from: "from@example.com"   def registration_confirmation(user)     mail(:to => user.email, :subject => "Registered" )

  end end

and I prepared registration_confirmation.txt.erb

Could anyone find what's wrong with it ?

Thanks in advance.

What happens when you run the following in the console?

user = User.first UserMailer.registration_confirmation(user).deliver
