How is that setting even working? You're using some early v2.0? It's
supposed to fail:

Error: user x: Initialization failed: Namespace '': Unknown setting:
maildir

Maildir++ quota works only when delivering to Maildir. If you want to
use some quota backend that works with both mboxes and maildirs, you
