Alerting

Error when enabling TLS for email.

We recently updated our Splunk infrastructure to 8.1 and before we upgraded, the enable TLS option was checked on the mail server settings. The alert_actions.conf has not changed at all. Now for emails being sent, we receive the following error in the python.log:

sendemail:456 - [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:742) while sending mail to: <EMAIL_ADDRESS>
 
If I manually add use_tls = 1 in that conf file, there are no errors, but if enabled on the web UI, it errors with the above. 
 
I am not sure what else to check here as nothing has changed except for the upgrading of the Splunk version on the servers. Has anyone else experienced this?

Hi. Did you see this Splunk answers?

Sounds like a possible cipher suite issue.
