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

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