Barring any weird bug in Gnus, this leads me to think that Gnus is not
thinking of this folder as in it's active select methods...
And I think I know why. See how it is trying to place the archive
inside the Jun-2006 dir? This must be preventing Gnus from considering
that as a managed group. Try:

(setq nnmail-expiry-target
        '(lambda (group)
         (concat "nnfolder:"
                 (format-time-string "%b-%Y-" (current-time))
                 group)))

Notice that I replaced the '.' after the year with a dash.

Yes. That is how elisp handles updates to files.

They will only be opened if:
     a) You accessed them and did not exit the group
     b) Some messages were recently expired there.

If the change I suggest above does not do it, then it is the only one
_I_ see. Maybe someone more knowledgeable here can give a better suggestion.
