title: Email-Ext - Send email to Git committer only
body: <p>I am currently trying to set up our Jenkins to send emails when the build succeeded or failed. I want to use email-ext for this job. I want to send emails to the git committers only because I don't want to spam any other recipients. This is why I left the global recipient list empty.</p>
  
  <p>However, when I configure a trigger to send an email to the developers ("send to recipient list" and "send to requestor" are unchecked) it fails with the following error:</p>
  
  <pre><code>Email was triggered for: Failure
  Sending email for trigger: Failure
  An attempt to send an e-mail to empty list of recipients, ignored.
  </code></pre>
  
  <p>I don't want to send to a list of recipients. The only one, who should receive an email, should be the git committer of the last commit. How do I do that?</p>
