Problem Analysis

The problem is that host is not configured correctly in SMTP

Solution

If you are using a corporate mailbox, host needs to configure the enterprise domain name, for example, the following configuration:

##################################################### SMTP / Emailing #######################################################################
[smtp]
enabled = true
host = smtp.ymatrix.cn:25
user = [email protected]
# If the password contains # or ; you have to wrap it with triple quotes. Ex """#password;"""
password = *****
;cert_file =
;key_file =
skip_verify = true
from_address = [email protected]
from_name = MatrixDBGrafana
# EHLO identity in SMTP dialog (defaults to instance_name)
;ehlo_identity = dashboard.example.com
# SMTP startTLS policy (defaults to 'OpportunisticStartTLS')
;startTLS_policy = NoStartTLS

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