Alert notification timeout

I am not able to send test email notification. I am getting this error on dashboard

Failed to send test alert.: failed to send notification to email addresses: firstname.lastname@email: dial tcp 172.217.194.26:587: i/o timeout

The SMTP configurations are as follows :

#################################### SMTP / Emailing ##########################
[smtp]
enabled = true
host = smtp.google.com:587
user = sender@email

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

password = ********
cert_file =
key_file =
skip_verify = false
from_address = sender@email
from_name = Grafana

EHLO identity in SMTP dialog (defaults to instance_name)

;ehlo_identity = dashboard.example

SMTP startTLS policy (defaults to ‘OpportunisticStartTLS’)

startTLS_policy = NoStartTLS

The logs are as follows
