13. 资料性参考文献

本节列出 Message Submission 相关的资料性参考文献. 这些文献帮助读者理解 SMTP submission 与传统 SMTP 传输、邮件格式、认证、安全传输、增强状态码和投递状态通知之间的关系. 文献条目中的作者、英文题名、RFC 编号和日期保持原文, 中文括注只用于说明标题含义.

从实现角度看, SMTP 扩展类引用说明服务器和客户端可能协商的能力, 例如 8BITMIME、CHUNKING、PIPELINING、SIZE、STARTTLS、SMTP AUTH 和增强错误码. 邮件访问或消息格式类引用则说明 submission 服务最终处理的是符合 Internet Message Format 和 MIME 规则的消息. 安全相关引用用于提醒实现者, submission 不只是转发消息, 还常常承担认证、策略执行和安全通道建立的职责.

这些条目是资料性引用, 不单独引入新的强制要求. 如果某个部署启用了其中某项扩展, 应以对应 RFC 的规范性文字为准, 再结合 RFC 4409 对 submission 端口和客户端行为的要求进行实现.
