And i am trying to enable email notification on grafana. By enabling SMTP. But

I am new to grafana world and trying to setup on Azure kubernetes services to get alerts for whenever our application pod goes down. Through helm i have installed prometheus-grafana and grafana dashboard is up and running perfect.

Now i am trying to set alerts and send notifications.I have added below smtp config in grafana.ini file.
enabled = true
host = test:25
user =
password = password
skip_verify = true
from_address =
from_name = Grafana
startTLS_policy = NoStartTLS

And when i am testing email on grafana dashboard facing the issue attached as image here - SMTP Not configured check your grafana.ini config file’s SMTP Section.
Also logs path is /var/log/grafana. But not able to see any logs about where the config is missing.

Thank you in advance.
