Forum: Ruby on Rails How can i send email with ruby on rails 3.1 ?

I have installed sendmail .

I have read this => 
http://guides.rubyonrails.org/action_mailer_basics.html

I need to do =>

rails generate mailer UserMailer

app/mailers/user_mailer.rb =>

class UserMailer < ActionMailer::Base
  default :from => "notifications@example.com"

  def welcome_email(user)
    @user = user
    @url  = "http://example.com/login"
    mail(:to => user.email, :subject => "Welcome to My Awesome Site")
  end
end

What will be the email address of :from => .. ?

I need to send email to @yahoo.com, @gmail.com and in any domain like
abc@anydomain.com.

How can i do this ?

It will be helpful if someone can reply with explaination ?

Form: ist whatever email you want it to be... the from field is the 
senders
address. So it could be you address or no-reply@example.com or similar. 
But
it would be good advise if you ensure ownership  over the used domain or 
at
least the used email address.
