| `imap_server`, `imap_port` | IMAP server (e.g. 993 with TLS). |
| `username`, `password` | Mailbox login; 163/QQ require app password. |
| `mailbox` | Folder to watch (default `INBOX`). |
| `use_idle` | `true`: use IMAP IDLE when supported (push); `false`: poll every `check_interval` seconds. |
| `check_interval` | Polling interval in seconds when IDLE is off or unsupported (default 30). |
| `forced_polling` | When the server does not implement IDLE/NOOP per spec, set `true` to use application-level polling; leave `false` normally. |
| `check_interval` | Polling interval in seconds when using forced polling or when IDLE is unsupported (default 30). |
| `allow_from` | Allowed sender addresses; only their mails trigger the agent. |
| `attachment_dir` | Directory to save attachments; leave empty to skip saving. |
| `smtp_server`, `smtp_port`, `smtp_use_tls` | Optional; if set, the agent can send replies. |
