title: Preventing Delivery Status Notification Errors or email replys
body: <p>I have a web application (L/WAMP)
  It is hosted using the domain abc.com</p>
  
  <p>Clients use the application from company 123.com which means their email address is something like jason@123.com or bob@123.com.</p>
  
  <p>The application will sometimes send out an email to jason@123.com telling him that Bob has does something like approved or rejected his daily time entries.  The system sends this email for Bob automatically.  This email is sent to jason@123.com from system@abc.com.</p>
  
  <p>We're doing it that way to try to make sure the email ends up in the inbox instead of the spam filter.</p>
  
  <p>So, my question is, is there a way to prevent the recipient from replying to the email (we provide a note with a link to mail the person direct using their 123.com email address) or from the recipient's email server sending back things like Out of the Office replies or Delivery Status Notifications?</p>
  
  <p>Is there anything I can do in the address field or the email header that will tell the recipient's email server not try send anything back to system@abc.com?</p>
  
  <p>Any help would be great...</p>
