title: I am using Jenkins CI, and I am trying to set up the ability to send emails. However I am unable to connect to the SMTP host
body: <p>I am unable to connect to a SMTP host using the E-mail Notification abilities in Jenkins. I believe I have everything set up correctly. This is my configuration:</p>
  
  <p>SMTP Server: smtp.gmail.com </p>
  
  <p>Default user e-mail suffix: @gmail.com </p>
  
  <p>Use SMTP Authentication: checked User </p>
  
  <p>Name: myUsername@gmail.com Password: myGmailPassword </p>
  
  <p>Use SSL: checked SMTP Port: 465 </p>
  
  <p>Reply-To Address: NOREPLY@gmail.com Charset: UTF-8</p>
  
  <p>I have disabled any antivirus and firewalls on the machine that Jenkins is running on. This is the error I am running into:</p>
