extra sent-to-xxxx folders/files

[jeff.rancier@softechnics.com (Jeffery B. Rancier)]

I've recently upgraded to Oort Gnus 0.13, and noticed *extra* files
hanging around in my ~/Mail/ directories.  First of all my gnus:

,----[ .gnus ]
| ;; -*- emacs-lisp -*-
| (require 'message-x)
| (setq gnus-select-method '(nntp "news.gmane.org"))
| (setq gnus-message-archive-group
|       '(("^alt" "sent-to-alt")
| 	("mail" "sent-to-mail")
| 	(".*" "sent-to-misc")))
| 
| (add-hook 'gnus-group-mode-hook 'gnus-topic-mode)
| 
| ;; THIS DOESN'T SEEM TO WORK
| ;; (setq gnus-secondary-select-methods '((nnml "")(nnslashdot "")))
| 
| (setq gnus-secondary-select-methods '((nnml "")))
| (setq nnmail-spool-file "po:jrancier")
| (setq mail-sources '((pop :server "my-mail-server"
|                           :user "my-user-name"
| 			  :password "my-password")))
| 
| ;; THIS DOESN'T SEEM TO WORK
| ;; Automatically check for mail every 5 minutes:
| 
| (gnus-demon-add-handler 'gnus-demon-scan-mail 5 t)
| (gnus-demon-init)

Regarding:

 (setq gnus-message-archive-group
   '(("^alt" "sent-to-alt")
   ("mail" "sent-to-mail")
   (".*" "sent-to-misc")))

I now have to sent-to-misc groups,

         151: nnfolder+archive:sent-to-misc 
         155: nnfolder+archive:sent-to-misc. 

When I look in my ~/Mail/archive directory I see the following:

  -rw-rw-rw-   1 jrancier root       67 Feb  6 09:03 active
  -rw-rw-rw-   1 jrancier root   277214 Dec 26 10:55 sent-to-mail
  -rw-rw-rw-   1 jrancier root       19 Jan 24 14:07 sent-to-mail.mrk
  -rw-rw-rw-   1 jrancier root  3522075 Feb  6 08:39 sent-to-misc
  -rw-rw-rw-   1 jrancier root       10 Feb  6 08:25 sent-to-misc..mrk
  -rw-rw-rw-   1 jrancier root    38763 Feb  5 13:05 sent-to-misc..nov
  -rw-rw-rw-   1 jrancier root       94 Jan 28 20:00 sent-to-misc.mrk
  -rw-rw-rw-   1 jrancier root    40884 Feb  6 08:39 sent-to-misc.nov

Where did the other files come from?  Incorrect setting?

Also in ~/Mail/ I have have a few hundred files like:

  -rw-rw-rw-   1 jrancier root    24893 Feb  5 08:13 Incoming1092StA
  -rw-rw-rw-   1 jrancier root     2559 Feb  5 08:31 Incoming1092Tgf
  -rw-rw-rw-   1 jrancier root     4923 Feb  5 08:56 Incoming1092TnT
  -rw-rw-rw-   1 jrancier root   255356 Feb  5 08:09 Incoming1092gjx
  -rw-rw-rw-   1 jrancier root    51619 Feb  5 09:08 Incoming1092gxZ
  -rw-rw-rw-   1 jrancier root     8977 Feb  5 08:44 Incoming1092sIB
  -rw-rw-rw-   1 jrancier root     5368 Feb  5 09:13 Incoming1092t7f
  -rw-rw-rw-   1 jrancier root    67343 Feb  3 13:18 Incoming1204-4C
  -rw-rw-rw-   1 jrancier root     1815 Feb  3 10:10 Incoming1204-xO

Is this from the recently added gnus-demon stuff I recently added?
Can I delete these?
