SMTP config issue V6.7.3

Hello Guys, I installed Grafana on windows OS, I want to create notification channels, but when I always press “Send Test”, it always gives me error “SMTP not configured on grafana configuration”. As far as I know, what I need to edit is the sample.ini in grafana/conf folder ? Am I right in this? this is my configuration looks like:
smtp]

enabled = true

host = smtp.gmail.com:465

user = mygmail@gmail.com

If the password contains # or ; you have to wrap it with triple quotes. Ex “”"#password;"""

password = myP@ssword

;cert_file =

;key_file =

skip_verify = true

from_address = name

from_name = Admin

is there something wrong with my configurations?

Thank you !

Regards,
