Is this working earlier or is this first time when you are trying it? Can you change from=splunk@your.doma.in?

First time, this is new Splunk cluster setup on AKS using Splunk Operator

Ok. Then the configuration is quite probably somehow broken.

Basically you should define the next to alert_actions.conf:

[default]
hostname = https://YOUR.SPLUNK.URL:PORT
mailserver = YOUR.MAIL.SERVER:PORT
use_ssl = 0
use_tls = 0
from = splunk@YOUR.MAIL.DOMAIN 

 Use_ssl & use_tls based on what your mail server is needing and also password for that user if needed.
