已发送Grafana警报测试通知,但未收到任何电子邮件

我想测试格拉瓦纳警报。我想在有警报时接收电子邮件。所以首先我在grafana.in i文件中设置了smtp:

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

[emails]
;welcome_email_on_sign_up = false

在Grafana的测试中,我设置了名称、类型:email、发送所有警报、包括图片。 我的电子邮件在Hotmail上。

当我按下发送测试时,我收到发送的测试通知,但没有收到电子邮件…

这是日志:

我也用Gmail做过测试,结果是一样的。
