IANA 注册流程​

本规范遵循 RFC 3864 定义的 Permanent Message Header Field 注册流程:

  1. 注册请求: 提交给 IANA
  2. 审查流程: IESG 审查
  3. 注册批准: IANA 批准并记录
  4. 公开访问: 发布在 IANA 网站上

永久消息头部字段库 (Permanent Message Header Field Repository)​

由 IANA 维护的 Permanent Message Header Field Repository 包含:

  • 标准化头部字段
  • 实验性头部字段
  • 临时头部字段
  • 过时头部字段

访问地址: https://www.iana.org/assignments/message-headers/

摘要​

RFC 5322 在 IANA 注册 23 个标准头部字段和 1 个过时字段, 更新了先前的 RFC 2822 注册项. 所有注册项均遵循 RFC 3864 定义的流程, 并由 IANA 维护在 Permanent Message Header Field Repository 中.
