How to use SMTP AUTH for action.email.mailserver emails?

[mashery]

I need alert emails generated by saved search monitors to be delivered via an email server that requires SMTP Authentication.

How can I specify SMTP AUTH credentials with action.email.* values?

[araitz]

SMTP authentication should be possible in Splunk 4.2.

GERALD,

Can you post a sample sendemail.py script that has been modified to do SMTP AUTH?

Thank you.

No, I can't. But it's just a matter of getting the credentials, then inserting a call to smtp.login() http://docs.python.org/library/smtplib.html#smtplib.SMTP.login after creating the smtp in the line smtp = smtplib.SMTP(serverURL).

There are a couple of ways to do this:

• You could customize and modify the sendemail.py python script that actually does the sending. The original is located in $SPLUNK_HOME/etc/apps/search/bin/. Rather than modifying the delivered file directly though (it will get clobbered on updates), you can create a version with a different name and either: override [sendemail] in etc/apps/search/default/commands.conf with a local .conf file, which will make Splunk just use the new version; or create a new commands.conf entry and override the command setting in the [email] stanza in etc/system/default/alert_actions.conf.
• Another way that some prefer is to leave Splunk unmodified and configure your own SMTP server (e.g., one that is already running on the Splunk server) to authenticate to and relay all mail to the desired authentication-requiring SMTP server, leave yours to accept mail with no authentication, and have Splunk send messages to this local server. (You'll want to make sure your server is reachable only locally in this case.) You would follow instructions to set up your local SMTP server to perform SASL authentication to the desired outbound relay.
