title: php.ini & SMTP= - how do you pass username & password
body: <p><code>My ISP</code> account requires that I send a username &amp; password for outbound <code>SMTP</code> mail. </p>
  
  <p>How do I get <code>PHP</code> to use this when executing <code>php.mail()?</code> The <code>php.ini</code> file only contains entries for the server <code>(SMTP= )</code> and <code>From: (sendmail_from= )</code>.</p>
