# 集成邮件系统

在 Alertmanager 使用邮箱通知，只需要定义好 SMTP 相关的配置，并且在 receiver 中定义接收方的邮件地址即可。

```yaml
global:
  [ smtp_from: <tmpl_string> ]
  [ smtp_smarthost: <string> ]
  [ smtp_hello: <string> | default = "localhost" ]
  [ smtp_auth_username: <string> ]
  [ smtp_auth_password: <secret> ]
  [ smtp_auth_identity: <string> ]
  [ smtp_auth_secret: <secret> ]
  [ smtp_require_tls: <bool> | default = true ]
```

完成全局 SMTP 之后，还需要为 receiver 配置 email\_configs，定义一组接收告警的邮箱地址，如下所示：

```yaml
name: <string>
email_configs:
  [ - <email_config>, ... ]
```

每个 email\_config 中定义相应的接收人邮箱地址、邮件通知模板等信息，如果当前接收人需要单独的 SMTP 配置，那直接在 email\_config 中进行覆盖。

```yaml
[ send_resolved: <boolean> | default = false ]
to: <tmpl_string>
[ html: <tmpl_string> | default = '{{ template "email.default.html" . }}' ]
[ headers: { <string>: <tmpl_string>, ... } ]
```

* 如果当前收件人需要接受告警恢复（global 中的 <mark style="color:blue;">**`resolve_timeout`**</mark>）的通知的话，在 email\_config 中定&#x4E49;**`send_resolved`**&#x4E3A; true。
* 如果所有的邮件配置使用了相同的 SMTP 配置，则可以直接定义全局的 SMTP 配置。
