I won't claim to understand how this is supposed to work, but in
`nnmaildir-open-server' we've got the following chunk of
lisp-as-imperative-code:

(setq x (assq 'target-prefix defs))
(if x
    (progn
      (setq x (cadr x)
	    x (eval x t))	;FIXME: Why `eval'?
      (setf (nnmaildir--srv-target-prefix server) x))
  (setq x (assq 'create-directory defs))
  (if x
      (progn
	(setq x (cadr x)
	      x (eval x t) ;FIXME: Why `eval'?
	      x (file-name-as-directory x))
	(setf (nnmaildir--srv-target-prefix server) x))
    (setf (nnmaildir--srv-target-prefix server) "")))

This makes it look to me like, if you've got a 'target-prefix set (even
if it's the empty string), then 'create-directory never comes into play
at all.

So maybe try taking out the (target-prefix "") server config completely?

I really don't know how this is meant to work. If you figure it out we
should update the manual.

Thanks,
