9.1. IMAP/JMAP 关键词注册
IANA 已在 "IMAP and JMAP Keywords" 注册表中注册以下 17 个 IMAP/JMAP 关键词. 所有条目的 Owner/Change controller 均为 IESG, Published specification 均为 RFC 9979. 关键词名称, Intended Usage 和 Scope 是注册表值, 因此保持英文原样; 中文表头用于说明每列含义.
| 关键词 | 设置/清除方 | 效果 | Intended Usage | Scope |
|---|---|---|---|---|
| $autosent | server on delivery | advisory | COMMON | BOTH |
| $canunsubscribe | server on delivery | advisory | COMMON | BOTH |
| $followed | client | can cause automatic action | COMMON | BOTH |
| $hasattachment | server or client | advisory | COMMON | BOTH |
| $hasmemo | client | advisory | COMMON | BOTH |
| $hasnoattachment | server or client | advisory | COMMON | BOTH |
| $imported | server on delivery | advisory | COMMON | BOTH |
| $istrusted | server on delivery | advisory | COMMON | BOTH |
| $MailFlagBit0 | client | advisory | COMMON | BOTH |
| $MailFlagBit1 | client | advisory | COMMON | BOTH |
| $MailFlagBit2 | client | advisory | COMMON | BOTH |
| $maskedemail | server on delivery | advisory | LIMITED USE | BOTH |
| $memo | client | advisory | COMMON | BOTH |

| $new | server; client can clear | advisory | LIMITED USE | BOTH |
| $notify | server; client may clear | can cause automatic action | COMMON | BOTH |

其中 advisory 表示提示性状态, can cause automatic action 表示该关键词可能触发自动操作. server on delivery, server or client, client 等字符串描述关键词通常由哪一方设置或清除.
9.2. IMAP 邮箱名称属性注册
IANA 还在 "IMAP Mailbox Name Attributes" 注册表中注册以下 IMAP 邮箱名称属性. 这些属性不隐含反斜杠, 这与 [RFC6154] 中的 special-use attributes 不同.
| 属性名称 | 描述 | 引用 |
|---|---|---|
| Snoozed | 存放临时延后处理消息的邮箱 | RFC 9979 |
| Scheduled | 存放计划稍后发送消息的邮箱 | RFC 9979 |
| Memos | 存放用户创建的备忘消息的邮箱 | RFC 9979 |
