Why can't grafana send email?

Pull grafana helm chart from official site.

Set email send configuration in values.yaml file:

enabled = true
host = smtp.gmail.com:587
user = sender@gmail.com
password = sender_password
;cert_file =
;key_file =
skip_verify = true
from_address = sender@gmail.com

Then install it at local:

$ helm install grafana

Test send email, failed. Don’t know why.

Check the grafana server log when that error happens.


Okay, I didn’t check log yet. Maybe the problem is smtp server not work. Thank you.
