SMTP requires user password?

I’m trying to setup SMTP for alerts and see the documentation says it requires the users password for email and was wondering why?

If it’s just sending an SMTP message and is allowed on our exchange server to do so, why does it require the users password to send that email? Or am I mistaken?

Config file looks like:

#################################### SMTP / Emailing ##########################
[smtp]
;enabled = true
;host = 10.10.10.10:25
;user = support@domain.com
“# If the password contains # or ; you have to wrap it with trippel quotes. Ex “””#password;"""
;password =
;cert_file =
;key_file =
;skip_verify = false
;from_address = grafana@domain.com
;from_name = Grafana

[emails]
;welcome_email_on_sign_up = false

Some SMTP servers require user/password authentication to send emails

I see, if I leave it blank and point it at our exchange server (which doesn’t require authentication if manually added to the connector) will it send?
