[Dovecot] DSync Namespace Frustration

[Marc Perkel]

In order to get dsync to work I need to set something in namespace. 
Running maildir. Will this work?

namespace private {
  separator = .
  prefix =
  inbox = yes
}
namespace private {
  separator = .
  prefix = INBOX.
  inbox = no
  hidden = yes
  list = no   # for v1.1+
}
