If you have any subscriptions=no namespaces, you need a parent namespace that has subscriptions=yes. You could have e.g.:

namespace {
  prefix = INBOX/
  list = no
  inbox = yes
}
namespace {
  prefix =
  list = no
  hidden = yes
  alias_for = INBOX/
}

So now the prefix="" is used for the subscriptions but nothing else really.

Anyway, INBOX/ isn't the same as INBOX. so if any client configs are using INBOX. as namespace prefix then they don't work with INBOX/.
