title: Rails mailer without view
body: <p>Is it possible to have a Rails mailer without any view ?</p>
  <p>When dealing with text-only mails, it would be cool to be able to put the body right in the mailer itself and not have to use a view for the action with just one line of text (or one I18n key).</p>
  <p>In a way, I'm looking for something like ActionController's &quot;render :text =&gt;&quot; but for ActionMailer.</p>
