是否广泛支持IMAP CONDSTORE? [英] Is IMAP CONDSTORE widely supported?

问题描述

我正在构建一个简单的Webmail，我想使用IMAP的CONDSTORE扩展名:它允许获取自日期以来发生了更改的所有内容(消息，标志等)，这对于同步电子邮件客户端到IMAP服务器.

I'm building a simple webmail and I would like to make use of the CONDSTORE extension for IMAP: it allows to fetch everything that has changed (messages, flags, …) since a date, which is very practical to synchronize the email client to the IMAP server.

但是我完全不知道大多数IMAP服务器是否实际上支持此IMAP扩展.

However I have absolutely no idea if this IMAP extension is actually supported by most IMAP servers or not.

那么有什么资料可以告诉我此扩展的支持程度如何?例如，GMail或Hotmail是否支持它?

So is there any kind of source that could tell me how well this extension is supported? For example, does GMail or Hotmail support it?

(这背后的隐患很明显:CONDSTORE是将我的电子邮件客户端同步到IMAP服务器的最合适方法吗?我在本地存储电子邮件副本，这就是为什么我需要同步)

(the hidden question behind this is obvious: is CONDSTORE the most appropriate way to synchronize my email client to the IMAP server? I store locally copies of emails, that's why I need synchronization)

推荐答案

不，它不受广泛支持.您可以将其视为在可用时可以使用的优化，但是您不能依赖它.您还需要一种跟踪已删除邮件的方法，这是condstore无法告诉您的

No, it is not widely supported. You can treat it as an optimization to use when available, but you cannot depend on it. You also need a way to track removed messages, which is not something condstore can tell you

但是，Gmail最近才推出了对此功能的支持.

Gmail, however, just rolled out support for it recently.
