how to send mail through ruby on rails

Plz tell me the code to send mail from ruby on rails.I have googled
many times but couldn't find a proper solution.

Railscasts is a great place to start looking for anything you wish to know pertaining to development in Ruby on Rails.

This episode demonstrates how to go about the setting up everything for being able to send emails.

For further information you should google for ActionMailer.

Thanks & Regards,
