There seems to be a misunderstanding. Chuck is not trying to open an
IMAP stream to a mail *server*, but instead to an mbox *file*.
Apparently this works on Linux, but not on Windows. According to
<https://bugs.php.net/bug.php?id=39880> this seems to be a problem of
the c-client library on Windows.
