title: Not able to send/receive email from Jenkins using Email-ext plugin
body: <p>I am using Jenkins ver. 1.463 running on 32-bit Windows Server. I have installed Email-ext plugin version 2.30.2.</p>
  
  <p>I am unable to get any email notifications.</p>
  
  <p>What i am trying to do - is send an email after every job - irrespective of whether the operation is success, failure, abort, not-build, etc..
  I am using Jenkins to run Automated Test Suites.</p>
  
  <p>The way i have configured a test job is "In the Post-Build Actions , have selected Editable Email Notification", and filled in the required fields(recipient list,etc). In the Advanced - selected all the triggers from dropdown such as "Success, Failure, Aborted, Regression, Fixed, Not-Built, Stable.</p>
  
  <p>i have verified the smtp server, recipients, Still I am unable to get any email,
   in the Console Output of the job i see the following lines</p>
  
  <blockquote>
    <p>Email was triggered for: Success<br>
    Sending email for trigger: Success.</p>
  </blockquote>
  
  <p>In the Jenkins Server, in the "jenkins.err.log", see the following error message / exception being thrown, but dont know the exact cause</p>
