;;; Commentary:

;;; Code:
|
||
|
||
;; Souped up by shane@mit-ajax based on ideas of rlk@athena.mit.edu
|
||
;; New features include attribute and keyword support, message
|
||
;; selection by dispatch table, summary by attributes and keywords,
|
||
;; expunging by dispatch table, sticky options for file commands.
|
||
|
||
;; Extended by Bob Weiner of Motorola
|
||
;; New features include: rmail and rmail-summary buffers remain
|
||
;; synchronized and key bindings basically operate the same way in both
|
||
;; buffers, summary by topic or by regular expression, rmail-reply-prefix
|
||
;; variable, and a bury rmail buffer (wipe) command.

|

Whenever Rmail shows a message in the folder that `rmail-file-name'

specifies, it calls `rmail-auto-file' to maybe file the message in
|
||
another folder according to this list. Messages that are already
|
||
marked as `filed', or are in different folders, are left alone.
|
||
|
||
Each element of the list is of the form:
|
||
|
||
(FOLDERNAME FIELD REGEXP [ FIELD REGEXP ] ... )
|
||
|
||
FOLDERNAME is the name of a folder in which to put the message.
|
||
If FOLDERNAME is nil then Rmail deletes the message, and moves on to
|
||
the next. If FOLDERNAME is \"/dev/null\", Rmail deletes the message,
|
||
but does not move to the next.
|
||
|
||
FIELD is the name of a header field in the message, such as
|
||
\"subject\" or \"from\". A FIELD of \"to\" includes all text
|
||
from both the \"to\" and \"cc\" headers.
|
||
|
||
REGEXP is a regular expression to match (case-sensitively) against
|
||
the preceding specified FIELD.
|
||
|
||
There may be any number of FIELD/REGEXP pairs.
|
||
All pairs must match for a directive to apply to a message.
|
||
For a given message, Rmail applies only the first matching directive.
|
||
|
||
Examples:
|
||
(\"/dev/null\" \"from\" \"@spam.com\") ; delete all mail from spam.com
|
||
(\"RMS\" \"from\" \"rms@\") ; save all mail from RMS.

the display of a MIME message between decoded presentation form and
