title: Automated email sending system - Spam Weight
body: <p>Good day,</p>
  
  <p>We have developed a system that send out automated mails to our clients, with a pdf attachment. Some of the clients have mentioned that the mails are being picked up as spam, and the IT guys say that the mails have a high spam confidence</p>
  
  <blockquote>
    <p>As mentioned the headers from your system include a 2.0 TotalSpamWeight, while it should be &lt; 0.</p>
  </blockquote>
  
  <p>What should I be looking at to change this?</p>
  
  <p>I am using Delphi 2010, indy 10's tidSMtp component to make the mails.
  The body is in html, and the images in the body are externally hosted.</p>
  
  <p>Please advise</p>
