  <p>I don't have enough rep to comment on the question so I have made a new one that refers to it. </p>
  
  <p>I need a way to check the attachments in openpop to see if it comes from a signature (typically small logos etc.) or from a big image that has been embedded in the body of the email. SmartPhones does typically this when you add a picture as attachment in many mail apps. </p>
