;;; 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'

another folder according to this list. Messages that are already

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,

|
||
|

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.

All pairs must match for a directive to apply to a message.

(\"/dev/null\" \"from\" \"@spam.com\") ; delete all mail from spam.com
