Question

理论上，Request For Comments（RFC）包含开发人员构建IMAP客户端时需要了解的所有内容。但是，要知道哪些RFC需要考虑以及哪些可以忽略，并不总是很容易。

有没有人有RFC路线图来引导开发人员通过这个？通过RFC路线图，我的意思是：

需要的完整RFC列表阅读和理解，以便开发IMAP客户端。
表明哪些RFC不再存在需要考虑，因为他们已被取代。
相关RFC的摘要。
详细介绍了相关的RFC 彼此相互关联。
逻辑顺序的指示阅读并理解相关内容的RFC。

Answer 1

路线图合理地短。从IMAP 4rev1 RFC RFC 3501开始。它有一个Normative References附录，列出了它直接依赖的所有RFC，并在文档的适当位置引用了这些RFC。

真正关键的 - 你可以按此顺序阅读它们 - 互联网邮件格式（我建议RFC 5322而不是RFC 2822更新），MIME RFC（ RFC 2045，2046和2047），内容处置（RFC 2183），TLS（RFC 2595）和UTF-7（RFC 2152 ）处理非ASCII文件夹名称。

完成基线协议后，您将需要开始查看扩展。其中一些将使您的生活更轻松......当服务器也提供支持。你肯定想要IDLE（RFC 2177）和UIDPLUS（RFC 4315）。 SORT（RFC 5256）也是一个很好的，NAMESPACE（RFC 2342）可能很有用。您可能还需要处理一些额外的SASL身份验证机制，因此请从RFC 1731开始，然后根据需要从那里开始。
