help with sending mail in rails, bad tutorial

I'm tryi开发者_开发问答ng to follow this tutorial to send mail through rails:

http://www.tutorialspoint.com/ruby-on-rails-2.1/rails-send-emails.htm

Sendmail wasn't working on my machine, but I got it working when I deployed it.

The problem I'm having is that the @email variables and such don't show up in the mail when it's sent. What is wrong?

it's because this tutorial is outadated. See the Guide about mailing.
