MailKit搜索查询问题

如何解决MailKit搜索查询问题

我使用MailKit和IMAP Client。 GMail邮件没有问题，但是当我向另一台服务器发出相同的请求时，就会出现问题。即使使用条件MailKit.Search.SearchQuery.NotSeen进行的简单搜索也不起作用。我可以访问邮箱并且可以读取邮件，但是过滤器不起作用。唯一有效的过滤器是MailKit.Search.SearchQuery.All。同样，我无法使用InBox.AddFlags将标志从NotSeen更改为Seen，它仅适用于GMail。当我对MessageSummaryItems.BodyStructure使用Fetch方法时，它将返回TextBody = null。它只能在GMail上正常工作，还是必须修复某些服务器设置？

解决方法

根据日志，MailKit的Search(SearchQuery.Unseed)不返回任何结果是因为您的IMAP服务器返回了0个匹配项。
