Change From headers in ActionMailer

Hi All,

Is there a way to change the "From" mail header in ActionMailer?
Here's how my simple ActionMailer class look like:

class Notifier < ActionMailer::Base

  def contact_notification(person, email, message)
    recipients ""
    from email
    subject "Message from"
    body message

Ideally I want the output to look like this: "user_name <no->"

Many thanks in advance !
