title: PHP Mail Postfix
body: <p>I have a PHP program using the <code>mail()</code> function.  I have this running on a Linux server.  Normally it is setup to run over the Linux sendmail function but my machine is setup to use Postfix.</p>
  
  <p>Can I use the PHP mail function over postfix and if so does anyone know how to make that work? </p>
