How can i send email with ruby on rails 3.1?

I have installed sendmail .

I have read this =>

I need to do =>

rails generate mailer UserMailer

app/mailers/user_mailer.rb =>

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

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
[email protected].

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 [email protected] or similar.
But
it would be good advise if you ensure ownership over the used domain or
at
least the used email address.
