Unable to send email using 'sendemail' command

[jaredloo]

I'm trying to use the Splunk CLI to send out an email using the following search:

/opt/splunk/bin/splunk search "host=192.168.0.173 source="/var/log/secure" for * from * earliest=-59m latest=now | sendemail to="jared99@gmail.com" format="html" server=smtp.gmail.com:587 use_tls=1"

I have tested the first part of the command (before the '|' pipe) and it definitely works. However, it seems like no email is actually being sent.

Upon inspecting /opt/splunk/var/log/splunk/python.log, I see the following error:

2019-01-21 16:55:37,975 +0800 ERROR     sendemail:1341 - 'action.email.sendresults'

Inspecting /opt/splunk/etc/apps/search/bin/sendemail.py only reveals that the region around line number 1341 contains the following code:

 1326  def getAlertActions(sessionKey):
  1327      settings = None
  1328      try:
  1329          settings = entity.getEntity('/configs/conf-alert_actions', 'email', sessionKey=sessionKey)
  1330
  1331          logger.debug("sendemail.getAlertActions conf file settings %s" % settings)
  1332      except Exception as e:
  1333          logger.error("Could not access or parse email stanza of alert_actions.conf. Error=%s" % str(e))
  1334
  1335      return settings
  1336
  1337  results, dummyresults, settings = splunk.Intersplunk.getOrganizedResults()
  1338  try:
  1339      results = sendEmail(results, settings)
  1340  except Exception, e:
  1341      logger.error(e)
  1342  splunk.Intersplunk.outputResults(results)

Would appreciate if anyone could shed some light on how to get this working. Many thanks in advance!

You should find more details in splunkd.log and in the search log (via Job Inspector).
