title: PHPMailer + Cron = Duplicated emails
body: <p>When I use the PHPMailer library, my script runs fine from CLI, but when I run it using cron, multiple emails get sent out. I have a list of addresses to send to, then for every next mail recipient, excluding the first one, it sends duplicates.</p>
  <p>Example:</p>
  <blockquote>
  <p>I send a message to 3 mail recipients every ten minutes</p>
  <p>1st recipient received same email once.</p>
  <p>2nd recipient received same email twice.</p>
  <p>3rd recipient received same email three times.</p>
  <p>4th recip. four times... etc..</p>
  </blockquote>
  <p>The Code:<br />

  <p>The crontab :</p>
  <pre><code>0,10,20,30,40,50 * * * * /etc/webmin/cluster-cron/cron.pl 1353486136-28420
  </code></pre>
