MailKit GetSubfolders

Question

I am using Mailkit GetSubfolders method which emits this Request/Response to the server

C: A00000005 LIST "" "INBOX.%" RETURN (SUBSCRIBED CHILDREN STATUS (UIDVALIDITY))
S: * LIST (\HasNoChildren \UnMarked) "." INBOX.kkkk
S: * STATUS INBOX.kkkk (UIDVALIDITY 1491227899)
S: * LIST (\HasChildren \UnMarked) "." INBOX.Archive
S: * LIST (\HasChildren \UnMarked) "." INBOX.spam
S: * LIST (\Subscribed \HasNoChildren \UnMarked) "." INBOX.Sent
S: * STATUS INBOX.Sent (UIDVALIDITY 1491227490)
S: * LIST (\Subscribed \HasNoChildren \UnMarked) "." INBOX.Junk
S: * STATUS INBOX.Junk (UIDVALIDITY 1491227488)
S: * LIST (\Subscribed \HasNoChildren \UnMarked) "." INBOX.Drafts
S: * STATUS INBOX.Drafts (UIDVALIDITY 1491227487)
S: * LIST (\Subscribed \HasNoChildren \UnMarked) "." INBOX.Trash
S: * STATUS INBOX.Trash (UIDVALIDITY 1491227603)
S: A00000005 OK List completed (0.001 + 0.000 secs).

However I noticed Outlook and other mail client shows more folders for my account that I am getting with MailKit GetSubfolders. In particular INBOX.INBOX.dfgdfg folder. I executed LIST "" "INBOX.*" (changing % to *) and I see this time the server returns the missing folder (see below). My question is how to get to INBOX.INBOX.dfgdfg folder using MailKit methods?

C: A00000005 LIST "" "INBOX.*" RETURN (SUBSCRIBED CHILDREN STATUS (UIDVALIDITY))
S: * LIST (\HasNoChildren \UnMarked) "." INBOX.kkkk
S: * STATUS INBOX.kkkk (UIDVALIDITY 1491227899)
S: * LIST (\HasChildren \UnMarked) "." INBOX.Archive
S: * LIST (\Subscribed \HasNoChildren \UnMarked) "." INBOX.Archive.000
S: * STATUS INBOX.Archive.000 (UIDVALIDITY 1491227889)
S: * LIST (\HasNoChildren \UnMarked) "." INBOX.Archive.aaaaa
S: * STATUS INBOX.Archive.aaaaa (UIDVALIDITY 1491227877)

Answer 1

I was able to answer my question. ImapClient.GetFolders is returning all the folders in the namespace including the missing INBOX.INBOX.dfgdfg

Answer 2

You are meant to call GetSubfolders() on each folder returned by GetSubfolders() if you want to recurse.

The problem with using * is that on some IMAP servers (cough UW.IMAPd cough), if the user has symlinks, the server response will never end because it does not properly detect symlink recursion.
