13 ;; A replacement for parts of Emacs' sendmail.el (specifically,
14 ;; it's what handles your outgoing mail after you hit C-c C-c in mail
15 ;; mode). See below for a list of additional features, including the
16 ;; ability to queue messages for later sending. If you are using
17 ;; fakemail as a subprocess, you can switch to feedmail and eliminate
18 ;; the use of fakemail. feedmail works with recent versions of
19 ;; Emacs (mostly, but not exclusively, tested against 19.34 on
20 ;; Win95; some testing on 20.x) and XEmacs (tested with 20.4 and
21 ;; later betas). It probably no longer works with Emacs 18,
22 ;; though I haven't tried that in a long time. Sorry, no manual yet
23 ;; in this release. Look for one with the next release.
25 ;; As far as I'm concerned, anyone can do anything they want with
26 ;; this specific piece of code. No warranty or promise of support is
27 ;; offered. This code is hereby released into the public domain.
29 ;; Thanks: My thanks to the many people who have sent me suggestions
30 ;; and fixes over time, as well as those who have tested many beta
31 ;; iterations. Some are cited in comments in code fragments below,
32 ;; but that doesn't correlate well with the list of folks who have
33 ;; actually helped me along the way.
35 ;; If you use feedmail, I invite you to send me some email about it.
36 ;; I appreciate feedback about problems you find or suggestions for
37 ;; improvements or added features (even though I can't predict when
38 ;; I'll incorporate changes). It's also OK with me if you send me a
39 ;; note along the lines of "I use feedmail and find it useful" or "I
40 ;; tried feedmail and didn't find it useful, so I stopped using it".
42 ;; It is most useful, when sending a bug report, if you tell me what
43 ;; version of Emacs you are using, what version of feedmail you are
44 ;; using, and what versions of other email-related elisp packages you
45 ;; are using. If in doubt about any of that, send the bug report
49 ;; A NOTE TO THOSE WHO WOULD CHANGE THIS CODE... Since it is PD,
50 ;; you're within your rights to do whatever you want. If you do
51 ;; publish a new version with your changes in it, please (1) insert
52 ;; lisp comments describing the changes, (2) insert lisp comments
53 ;; that clearly delimit where your changes are, (3) email me a copy
54 ;; (I can't always consistently follow the relevant usenet groups),
55 ;; and (4) use a version number that is based on the version you're
56 ;; changing along with something that indicates you changed it. For
59 ;; (defconst feedmail-patch-level "123")
60 ;; (defconst feedmail-patch-level "123-XYZ-mods")
62 ;; The point of the last item, of course, is to try to minimize
63 ;; confusion. Odds are good that if your idea makes sense to me that
64 ;; it will show up in some future version of feedmail, though it's
65 ;; hard to say when releases will tumble out.
68 ;; This file requires the mail-utils library.
70 ;; This file requires the smtpmail library if you use
71 ;; feedmail-buffer-to-smtpmail.
73 ;; This file requires the custom library. Unfortunately, there are
74 ;; two incompatible versions of the custom library. If you don't have
75 ;; custom or you have the old version, this file will still load and
76 ;; work properly. If you don't know what custom is all about and want
77 ;; to edit your user option elisp variables the old fashioned way,
78 ;; just imagine that all the "defcustom" stuff you see below is really
79 ;; "defvar", and ignore everthing else. For info about custom, see
80 ;; <URL:http://www.dina.kvl.dk/~abraham/custom/>.
82 ;; This code does in elisp a superset of the stuff that used to be done
83 ;; by the separate program "fakemail" for processing outbound email.
84 ;; In other words, it takes over after you hit "C-c C-c" in mail mode.
85 ;; By appropriate setting of options, you can still use "fakemail",
86 ;; or you can even revert to sendmail (which is not too popular
87 ;; locally). See the variables at the top of the elisp for how to
88 ;; achieve these effects (there are more features than in this bullet
89 ;; list, so trolling through the variable and function doc strings may
90 ;; be worth your while):
92 ;; --- you can park outgoing messages into a disk-based queue and
93 ;; stimulate sending them all later (handy for laptop users);
94 ;; there is also a queue for draft messages
96 ;; --- you can get one last look at the prepped outbound message and
97 ;; be prompted for confirmation
99 ;; --- removes Bcc:/Resent-Bcc: headers after getting address info
101 ;; --- does smart filling of address headers
103 ;; --- calls a routine to process Fcc: lines and removes them
105 ;; --- empty headers are removed
107 ;; --- can force From: or Sender: line
109 ;; --- can generate a Message-Id: line
111 ;; --- can generate a Date: line; the date can be the time the
112 ;; message was written or the time it is being sent
114 ;; --- strips comments from address info (both "()" and "<>" are
115 ;; handled via a call to mail-strip-quoted-names); the
116 ;; comments are stripped in the simplified address list given
117 ;; to a subprocess, not in the headers in the mail itself
118 ;; (they are left unchanged, modulo smart filling)
120 ;; --- error info is pumped into a normal buffer instead of the
123 ;; --- just before the optional prompt for confirmation, lets you
124 ;; run a hook on the prepped message and simplified address
127 ;; --- you can specify something other than /bin/mail for the
130 ;; --- you can generate/modify an X-Mailer: message header
132 ;; After a long list of options below, you will find the function
133 ;; feedmail-send-it. Hers's the best way to use the stuff in this
136 ;; Save this file as feedmail.el somewhere on your elisp
137 ;; loadpath; byte-compile it. Put the following lines somewhere in
138 ;; your ~/.emacs stuff:
140 ;; (setq send-mail-function 'feedmail-send-it)
141 ;; (autoload 'feedmail-send-it "feedmail")
143 ;; If you plan to use the queue stuff, also use this:
145 ;; (setq feedmail-enable-queue t)
146 ;; (autoload 'feedmail-run-the-queue "feedmail")
147 ;; (autoload 'feedmail-run-the-queue-no-prompts "feedmail")
148 ;; (setq auto-mode-alist (cons '("\\.fqm$" . mail-mode) auto-mode-alist))
150 ;; If you are using the desktop.el library to restore your sessions, you might
151 ;; like to add the suffix ".fqm" to the list of non-saved things via the variable
152 ;; desktop-files-not-to-save.
154 ;; If you are planning to call feedmail-queue-reminder from your .emacs or
155 ;; something similar, you might need this:
157 ;; (autoload 'feedmail-queue-reminder "feedmail")
159 ;; If you ever use rmail-resend and queue messages, you should do this:
161 ;; (setq feedmail-queue-alternative-mail-header-separator "")
163 ;; If you want to automatically spell-check messages, but not when sending
164 ;; them from the queue, you could do something like this:
166 ;; (autoload 'feedmail-mail-send-hook-splitter "feedmail")
167 ;; (add-hook 'mail-send-hook 'feedmail-mail-send-hook-splitter)
168 ;; (add-hook 'feedmail-mail-send-hook 'ispell-message)
170 ;; If you are using message-mode to compose and send mail, feedmail will
171 ;; probably work fine with that (someone else tested it and told me it worked).
172 ;; Follow the directions above, but make these adjustments instead:
174 ;; (setq message-send-mail-function 'feedmail-send-it)
175 ;; (add-hook 'message-mail-send-hook 'feedmail-mail-send-hook-splitter)
177 ;; I think the LCD is no longer being updated, but if it were, this
178 ;; would be a proper LCD record. There is an old version of
179 ;; feedmail.el in the LCD archive. It works but is missing a lot of

1365 "A fiddle-plex is a concise way of specifying header field fiddling.
1366 It is a list of up to 4 elements: NAME, VALUE, ACTION, FOLDING. The element
1367 VALUE can also be a list sometimes.
1369 NAME is the name of the header field to be fiddled with. Although case
1370 doesn't matter in looking for headers, case of NAME is preserved when a header
1371 is inserted via fiddling. It shouldn't include the trailing colon.
1373 VALUE is either nil, a simple string, a function returning nil or a string, or,
1374 as described below for ACTION `combine', a list of up to three values.
1376 ACTION describes the nature of the fiddling to be done. Possibilities
1377 for ACTION (default is `supplement'):
1379 `supplement' Leave other like fields as-is, insert this one.
1381 `replace' Delete other like fields, if any, and insert this one.
1383 `create' Insert this one only if no like field exists.
1385 `combine' Combine aggregate values of like fields with this one.
1386 In this case, VALUE has a special form. It is a list
1387 of three items: VAL-PRE, VAL-LIKE, and VAL-POST.
1388 VAL-PRE and VAL-POST are strings or nil. VAL-LIKE may
1389 be either a string or a function (it may also be nil,
1390 but there's not much point to that).
1392 Values of like header fields are aggregated, leading and
1393 trailing whitespace is removed, and embedded
1394 whitespace is left as-is. If there are no like
1395 fields, or the aggregate value is an empty string,
1396 VAL-LIKE is not used. Else, if VAL-LIKE is a function,
1397 it is called with two arguments: NAME and the
1398 aggregate like values. Else, if VAL-LIKE is a string, it is
1399 used as a format string where a single \%s will be
1400 replaced by the aggregate values of like fields.
1402 VAL-PRE, the results of using VAL-LIKE, and VAL-POST
1403 are concatenated, and the result, if not nil and not
1404 an empty string, is used as the new value for the
1405 field. Although this description sounds a bit
1406 complicated, the idea is to provide a mechanism for
1407 combining the old value with a new value in a flexible
1408 way. For example, if you wanted to add a new value to
1409 an existing header field by adding a semi-colon and
1410 then starting the new value on a continuation line,
1411 you might specify this:
1413 (nil \"%s;\\n\\t\" \"This is my new value\")
1415 FOLDING can be nil, in which case VALUE is used as-is. If FOLDING is
1416 non-nil, feedmail \"smart filling\" is done on VALUE just before
