I investigated further and indeed there is a problem.
As I said my university switched to gmail. Now someone sent me, using
his Apple Mail app, a mail with the following headers

From: User1 <user@ucm.es>
Subject: Blabla
To: User2 <user2@ucm.es>
Date: Wed, 22 Feb 2017 08:39:23 +0100 (1 year, 7 weeks, 1 day ago)
Bcc: oub@mat.ucm.es


So you see I am only on the BCC field which is displayed. Now I hit F
(as I do automatically and which in this case was a big mistake because
it results in

To: User1 <user@ucm.es>
Subject: Blabla
CC: User2 <user2@ucm.es>
Date: Wed, 22 Feb 2017 08:39:23 +0100 (1 year, 7 weeks, 1 day ago)
Bcc: oub@mat.ucm.es

And resulted in a somehow uncomfortable situation.

Meanwhile I did the following

(defun my-check-bcc ()
  "Try to avoid painful situations when using followup, and there is a Bcc field."
  (interactive)
  (cond ((and gnus-article-reply
              (message-with-reply-buffer
                (re-search-forward
                 "^Bcc:\\|BCC:\\|bcc:"
                 nil t)))
         (condition-case nil
             (progn
               (message-remove-header "cc")
               (message-goto-body)
               (message "There is a BCC field, we have deleted it!!!"))
           (error
            (progn
                (message "Followup??")))))))

(add-hook 'gnus-message-setup-hook 'my-check-bcc)


Any thoughts or comments?
