- 在 worker 的 `设置` -> `变量` 中添加以下变量：
| 变量名 | 说明 | 示例 |
| ---------------- | --------------------------- | --------------------- |
| DKIM_DOMAIN | 必填，域名后缀 | `vmail.dev` |
| DKIM_PRIVATE_KEY | 必填，DKIM 私钥 | `MIIEpQIBAAKCAQEA...` |
| DKIM_SELECTOR | 必填，固定值 `mailchannels` | `mailchannels` |
`DKIM_PRIVATE_KEY` 后续会提到如何获取。
记住 worker 分配的地址，即 `https://
