title: Sending email to Office 365 account not getting non-delivery report
body: <p>I have a PHP script that sends out email from a non-Office 365 SMTP to Office 365 accounts. Messages get delivered successfully but when I send email to a non-existent email accounts on a domain that is on Office 365, I dont get any bounce emails. I have no problem getting bounce emails from Gmail or other domain that is not on Office 365 though.</p>
  
  <p>Anyone got an idea of why this would be? Am I missing a header?</p>
