Fail to set mail directories

[Philipp Haselwarter <philipp.haselwarter@gmx.de>]

Hi,

I've tried to move my gnus related directories from their default
location. For the most part, it seems to work, but there are a few
variables that seem to somehow magically get reset to the (true) default
values.
This entails for example recreation of ~/Mail/drafts/ as soon as I start
composing mail (although `nndraft-directory' points to
"~/.emacs.d/gnus/News/drafts/").

As far as I can tell, the variables concerned are:

nntp-marks-directory, message-auto-save-directory,
gnus-article-save-directory, gnus-cache-directory,
gnus-kill-files-directory

They should be set up relative to gnus-directory and friends, but it
seems that the default values of those are used.

Strangely enough, when I « C-h v message-auto-save-directory RET », I
get this:

,----
| message-auto-save-directory is a variable defined in `message.el'.
| Its value is "/home/philipp/Mail/drafts/"
| Original value was 
| "/home/philipp/.emacs.d/gnus/Mail/drafts/"
| 
| Documentation:
| *Directory where Message auto-saves buffers if Gnus isn't running.
| If nil, Message won't auto-save.
| 
| You can customize this variable.
| 
| [back]
`----

Right now, my setup is

#+begin_src emacs-lisp
(eval-after-load "gnus" '(require 'my-gnus-config))
#+end_src

here's the relevant section in my-gnus-config:

#+begin_src emacs-lisp
(setq mail-default-directory
      (file-name-as-directory (expand-file-name "gnus" user-emacs-directory))
      gnus-directory
      (file-name-as-directory (expand-file-name "News" mail-default-directory))
      message-directory
      (file-name-as-directory (expand-file-name "Mail" mail-default-directory))
      mail-source-directory message-directory
      smtpmail-queue-dir
      (file-name-as-directory (expand-file-name "queued-mail" message-directory))
      smime-certificate-directory
      (file-name-as-directory (expand-file-name "certs"
      message-directory)))
#+end_src


What am I doing wrong? How do I debug this?
