STATUS fails with folders containing spaces

[jjb-pro]

I'm using MailKit to fetch the status of IMAP folders (e.g., unread count). It works well for most folders, but I'm encountering an issue when the folder name contains a space.

await mailFolder.StatusAsync(StatusItems.Unread | StatusItems.Count);

When the folder name contains a space, like "Folder Name", MailKit throws the following error:

C: A00000009 STATUS "Folder Name" (MESSAGES UNSEEN)
S: * STATUS Folder Name (MESSAGES 0 UNSEEN 0)
Syntax error in untagged STATUS response. Unexpected atom token: Name

I didn’t want to open an issue because this seems to be a server-specific problem. The same code works fine with other IMAP servers and the same folder name. On another server where it works, I get the following log:

C: B00000006 STATUS "Folder Name" (MESSAGES UNSEEN)
S: * STATUS "Folder Name" (MESSAGES 0 UNSEEN 0)
S: B00000006 OK STATUS completed

Is there a workaround to handle folder names with spaces to avoid triggering this error?

The problem is that the server isn't quoting the folder name in the response.

This is an extremely difficult problem to work around because the parser has no idea how many "words" are part of the folder name if they aren't quoted properly.

Thank you for your quick reply! And there's really nothing one can do about the problem? I have written an email app for Windows and everything works except the folders with spaces… Thanks anyway for such a great library!
