GNUS don't show all my emails

[Sébastien Gendre]

Hello world.

When I want to see all my emails with GNUS (C-U Enter), some e-mails
are not show. 


I use a personnal email address, mailboxs are provided by a dovecot
installation. Tested with another IMAP client, no problem.


This is the config I applied to GNUS:

(require 'gnus)
(setq gnus-init-file "~/.emacs.d/gnus.el")
(setq gnus-startup-file "~/.emacs.d/.newsrc")
(setq gnus-summary-line-format "%U%R %(%&user-date;%)  %-5,5L  %-
30,30f    %B%-80,80S\n"
      gnus-user-date-format-alist '((t . "%Y-%m-%d %H:%M"))
      gnus-thread-sort-functions '(gnus-thread-sort-by-date)
      gnus-sum-thread-tree-vertical "|"
      gnus-sum-thread-tree-root ""
      gnus-sum-thread-tree-false-root ""
      gnus-sum-thread-tree-indent " "
      gnus-sum-thread-tree-single-indent ""
      gnus-sum-thread-tree-leaf-with-other "├► "
      gnus-sum-thread-tree-single-leaf "╰► ")
(setq gnus-message-archive-group "nnimap+main-mail:Envoyés")
(add-hook 'message-setup-hook 'mml-secure-message-sign)
(add-hook 'message-mode-hook 'flyspell-mode)
(defun gnus-nnir-group-p (group)
  "Say whether GROUP is nnir or not."
  (if (gnus-group-prefixed-p group)
      (eq 'nnir (car (gnus-find-method-for-group group)))
    (and group (string-match "^nnir" group))))
    
    
    
Inside ~/.emacs.d/gnus.el I define my IMAP account:

(setq gnus-select-method
      '(nnimap "main-mail"
               (nnimap-address "exemple.com")
               (nnimap-server-port 666)
               (nnimap-stream ssl)
               (nnimap-inbox "INBOX")
;;             (nnimap-split-methods default)
               (nnimap-split-methods nil)
               (nnimap-expunge t)))



Anyone already have this problem?
