                   does not support mod-sequences.

  - Horde_Imap_Client::STATUS_SYNCFLAGUIDS
    Return key: syncflaguids
    Return format: (Horde_Imap_Client_Ids) If caching, the server
                   supports the CONDSTORE IMAP extension, and the
                   mailbox contained cached data when opened for the
                   first time in this access, this is the list of UIDs
                   in which flags have changed since STATUS_SYNCMODSEQ.

  - Horde_Imap_Client::STATUS_SYNCVANISHED
    Return key: syncvanished
    Return format: (Horde_Imap_Client_Ids) If caching, the server
                   supports the CONDSTORE IMAP extension, and the
                   mailbox contained cached data when opened for the
                   first time in this access, this is the list of UIDs

  - Horde_Imap_Client::STATUS_UIDNOTSTICKY
    Return key: uidnotsticky
    Return format: (boolean) If the server supports the UIDPLUS IMAP
                   extension, and the queried mailbox does not support
                   persistent UIDs, this value will be true. In all
                   other cases, this value will be false.

  - Horde_Imap_Client::STATUS_FORCE_REFRESH
    Normally, the status information will be cached for a given
    mailbox. Since most PHP requests are generally less than a second,
    this is fine. However, if your script is long running, the status
    information may not be up-to-date. Specifying this flag will ensure
    that the server is always polled for the current mailbox status
    before results are returned. (since 2.14.0)

  - Horde_Imap_Client::STATUS_ALL (DEFAULT)
    Shortcut to return 'messages', 'recent', 'uidnext', 'uidvalidity',
    and 'unseen' values.

$opts : array<string|int, mixed> = array()

Additional options:

  - sort: (boolean) If true, sort the list of mailboxes? (since 2.10.0)
          DEFAULT: Do not sort the list.
  - sort_delimiter: (string) If 'sort' is true, this is the delimiter
                    used to sort the mailboxes. (since 2.10.0)
                    DEFAULT: '.'
