Failed to send alert notification email - error="read tcp xxx->yyy :i/o timeout"

Hi,

I’m trying to send test alert notification to my company mail address configuring to company smtp server.

here is smtp config.

#################################### SMTP / Emailing #####################
[smtp]
enabled = true
host =companySTMPhost:port
user =companydomain\myusername
password =mypassword
;cert_file =
;key_file =
skip_verify = true
from_address = myusername@companydomain.com
from_name = Grafana
ehlo_identity =

[emails]
welcome_email_on_sign_up = false
templates_pattern = emails/*.html

Note:
Here i usually log in to outlook with user as “companydomain\myusername” with mypassword

And i’m trying to send notification mail to mycompany friend mail address - myfriendusername@companydomain.com.

but it is performing timeout error as follows.

Please help me to figure out the problem.

t=2018-09-25T10:43:52+0100 lvl=info msg=“Sending alert notification to” logger=alerting.notifier.email addresses=[myfriendusername@companydomain.com]

Not sure we can help , looks like Grafana cannot reach the smtp server on the host & port you defined.

this could be happened due to proxy ?

or this could be happened due to SSL ?
