IMAP mailboxes in the sidebar

[Felix Finch]

Ubuntu 18.04, Mutt 1.9.4.

    set sidebar_format="%B%?F? [%F]?%* %?N?%N/?%S"
    set sidebar_new_mail_only=no
    set sidebar_visible=yes

The sidebar shows only INBOX.  All other mailboxes are absent.  The same mutt sidebar is fine for local maildirs with a different muttrc.

I tried setting

    sidebar_whitelist =INBOX "=All Mail"

and that makes no difference.  I can change to that mailbox using "=All<tab>", so mutt knows it's a valid name, just can't see it in the sidebar.

I can only guess it's something to do with IMAP or Lookout (it's a Lookout IMAP server).
