title: Jenkins email-ext plugin not sending mail
body: <p>I have Jenkins version 1.480.3 installed on my machine and Email-Extention Plugin 2.30.2.</p>
  
  <p>Test mail from "Manage Jenkins" section works fine. When I add editable email notification to my jobs, I am not receiving it.</p>
  
  <p>Also tried configuring "Triggers" in editable email notification advanced section. That also didn work. Console logs of build shows email has been triggered.</p>
  
  <p>Can someone help me on how to debug this?</p>
