 **folder values**:
 - Local cache list and search: `inbox, sent, drafts, trash, spam, archive, other`, case-insensitive; server names (e.g. `INBOX`, `Sent Messages`) are accepted too. IMAP custom folders are all stored locally as `other`.
 - Remote sync: generic names (`inbox`, `sent`, ...) are mapped automatically to the actual IMAP folder, the Outlook folder, or the Gmail label; for IMAP you may also pass a `path` returned by `GET /imap/folders`. Gmail has no label for `archive`, so it fetches without filtering.
-- **IMAP single-message operations** (detail on a cache miss, mark as read/unread, delete, reply, attachment download) pass `folder` verbatim to the IMAP server, so it must be a real `path` returned by `GET /imap/folders` (e.g. `INBOX`, `Sent Messages`); it defaults to `INBOX` when omitted. The `folder` field of a list item is a normalized value (e.g. `sent`) and cannot be used as an IMAP folder name directly.

+**Mark as junk / Not junk**: moves the message into the junk folder, or out of it back to the inbox. The server and the local cache change together, and the response is `result: {id, folder}`.
+- Gmail swaps the `SPAM` / `INBOX` labels and keeps the `id`; Outlook and IMAP assign a new `id` after the move, so use the returned `id` for any later operation on this message. When the IMAP server lacks UIDPLUS the `id` is `null`; run `messages/fetch` on the destination folder before using the message again.
+- If the IMAP account has no junk folder on the server, the call returns 409 `imap_spam_folder_not_found`. Tell the user as is; do not retry and do not substitute another folder.
+- A message already in the destination folder returns success without moving. A message moved back to the inbox does not trigger mail rules or a new-mail notification.
+- Not junk handles one message at a time; do not move a batch back to the inbox together. Mark as junk may be called once per message.
+- Requires client 10.0.178 or later; older clients return 404, in which case ask the user to upgrade the client.
+
 **Extra fields in message detail**: `body: {content, contentType}`, `ccRecipients`, `attachments: [{id, filename, contentType, size}]`. For IMAP, an attachment's `id` is its index within the message as a string (`"0"`, `"1"`, ...).

 - 远程同步：通用名（`inbox`、`sent` 等）会自动映射到 IMAP 实际文件夹、Outlook 文件夹或 Gmail 标签；IMAP 也可直接传 `GET /imap/folders` 返回的 `path`。Gmail 的 `archive` 没有对应标签，会不加过滤地拉取。
