我正在使用Mailkit GetSubfolders方法向服务器发送此请求/响应

但是我注意到Outlook和其他邮件客户端显示了我使用MailKit GetSubfolders获取的帐户的更多文件夹。特别是INBOX.INBOX.dfgdfg文件夹。我执行了LIST＆＃34;＆＃34; ＆＃34; INBOX *＆＃34; （将％更改为*）我看到这次服务器返回丢失的文件夹（见下文）。我的问题是如何使用MailKit方法进入INBOX.INBOX.dfgdfg文件夹？

返回的每个文件夹上调用GetSubfolders()。
使用GetSubfolders()的问题在于某些IMAP服务器（ cough UW.IMAPd cough ），如果用户有符号链接，服务器响应将永远不会结束，因为它没有正确检测到符号链接递归。
