title: Whitelisting website email so it is not rejected as spam
body: <p>What are the processes I need to go through to make sure emails sent from my web server are not rejected as spam?  This question is for legitimate site emails that members have requested like a daily newsletter which is generated and run in a nightly process, as well as confirmation emails.</p>
  
  <p>Some of the ideas I've heard are:</p>
  
  <ol>
  <li>Making sure the server sending the
  mail has reverse-dns lookup turned
  on. </li>
  <li>Manually submitting a whitelist
  request to major ISPs.</li>
  </ol>
