;;; Commentary:

27

;;

28

;; This package provides the following new features for VM:

29

;;

30

;; A Pine-like postpone message function and folder. There are two new

31

;; functions. `vm-postpone-message' bound to [C-c C-p] in

32

;; the `vm-mail-mode' and the function `vm-continue-postponed-message'

33

;; is bound to [C] in a folder buffer.

34

;; The `vm-continue-what-message' imitates Pines message composing.

35

;; You can set `vm-mode-map' in the following way to get Pine-like.

36

;;

37

;; (define-key vm-mode-map "m" 'vm-continue-what-message)

38

;;

39

;; If you have postponed messages you will be asked if you want to continue

40

;; their composing, if you say "yes" you will visit the `vm-postponed-folder'

41

;; and you can select the message you would like to continue and press "m"

42

;; again! However be aware this works currently only if you expunge all

43

;; messages marked for deletion and save the postponed folder.

44

;;

45

;; You can also bind it to "C-x m" in order to check for postponed messages

46

;; when composing a message without starting VM.

47

;;

48

;; (autoload 'vm-continue-what-message-other-window "vm-pine" "" t)

49

;; (global-set-key "\C-xm" 'vm-continue-what-message-other-window)

50

;;

51

;;

52

;; Three new mail header insertion functions make life easier. The

53

;; bindings and names are:

54

;; "\C-c\C-f\C-a" vm-mail-return-receipt-to

55

;; "\C-c\C-f\C-p" vm-mail-priority

56

;; "\C-c\C-f\C-f" vm-mail-fcc

57

;; The variables `vm-mail-return-receipt-to' and `vm-mail-priority'

58

;; can be used to configure the inserted headers.

59

;; `vm-mail-fcc' can be configured by setting the variable

60

;; `vm-mail-folder-alist' which has the same syntax and default

61

;; value as `vm-auto-folder-alist'.

62

;; You may also add `vm-mail-auto-fcc' to `vm-reply-hook' in order to

63

;; automatically setup the FCC header according to the variable

64

;; `vm-mail-folder-alist'.

65

;; An there's another fcc-function `vm-mail-to-fcc' which set the FCC

66

;; according to the recipients email-address.

67

;;

68

;;; Bug reports and feature requests:

69

;; Please send a backtrace and the version number of vm-pine.el!

70

;; Feature requests are welcome!

;;; Code:
