File: feedmail.el.html

A replacement for parts of sendmail.el (specifically, it's what handles your outgoing mail after you hit C-c C-c in mail mode). See below for a list of additional features, including the ability to queue messages for later sending. This replaces the standalone fakemail program that used to be distributed with Emacs.

Sorry, no manual yet in this release. Look for one with the next release. Or the one after that. Or maybe later.

As far as I'm concerned, anyone can do anything they want with this specific piece of code. No warranty or promise of support is offered. This code is hereby released into the public domain.

Thanks: My thanks to the many people who have sent me suggestions
   and fixes over time, as well as those who have tested many beta
   iterations. Some are cited in comments in code fragments below,
   but that doesn't correlate well with the list of folks who have
   actually helped me along the way.

If you use feedmail, I invite you to send me some email about it. I appreciate feedback about problems you find or suggestions for improvements or added features (even though I can't predict when I'll incorporate changes). It's also OK with me if you send me a note along the lines of "I use feedmail and find it useful" or "I tried feedmail and didn't find it useful, so I stopped using it".

It is most useful, when sending a bug report, if you tell me what version of Emacs you are using, what version of feedmail you are using, and what versions of other email-related elisp packages you are using. If in doubt about any of that, send the bug report anyhow.

=====
A NOTE TO THOSE WHO WOULD CHANGE THIS CODE... Since it is PD, you're within your rights to do whatever you want. If you do publish a new version with your changes in it, please (1) insert Lisp comments describing the changes, (2) insert Lisp comments that clearly delimit where your changes are, (3) email me a copy
(I can't always consistently follow the relevant usenet groups),
and (4) use a version number that is based on the version you're changing along with something that indicates you changed it. For example,

       (defconst feedmail-patch-level "123")
       (defconst feedmail-patch-level "123-XYZ-mods")

The point of the last item, of course, is to try to minimize confusion. Odds are good that if your idea makes sense to me that it will show up in some future version of feedmail, though it's hard to say when releases will tumble out.
=====

This file requires the mail-utils library.

This file requires the smtpmail library if you use feedmail-buffer-to-smtpmail. It requires the smtp library if you use feedmail-buffer-smtp.

This file requires the custom library. Unfortunately, there are two incompatible versions of the custom library. If you don't have custom or you have the old version, this file will still load and work properly. If you don't know what custom is all about and want to edit your user option elisp variables the old fashioned way, just imagine that all the "defcustom" stuff you see below is really
"defvar", and ignore everything else. For info about custom, see
<URL:http://www.dina.kvl.dk/~abraham/custom/>.

This code does in elisp a superset of the stuff that used to be done by the separate program "fakemail" for processing outbound email. In other words, it takes over after you hit "C-c C-c" in mail mode. By appropriate setting of options, you can even revert to sendmail
(which is not too popular locally). See the variables at the top
of the elisp for how to achieve these effects (there are more features than in this bullet list, so trolling through the variable and function doc strings may be worth your while):

   --- you can park outgoing messages into a disk-based queue and
       stimulate sending them all later (handy for laptop users);
       there is also a queue for draft messages

   --- you can get one last look at the prepped outbound message and
       be prompted for confirmation

   --- removes Bcc:/Resent-Bcc: headers after getting address info

   --- does smart filling of address headers

   --- calls a routine to process Fcc: lines and removes them

   --- empty headers are removed

   --- can force From: or Sender: line

   --- can generate a Message-Id: line

   --- can generate a Date: line; the date can be the time the
       message was written or the time it is being sent

   --- strips comments from address info (both "()" and "<>" are
       handled via a call to mail-strip-quoted-names); the
       comments are stripped in the simplified address list given
       to a subprocess, not in the headers in the mail itself
       (they are left unchanged, modulo smart filling)

   --- error info is pumped into a normal buffer instead of the
       minibuffer

   --- just before the optional prompt for confirmation, lets you
       run a hook on the prepped message and simplified address
       list

   --- you can specify something other than /bin/mail for the
       subprocess

   --- you can generate/modify an X-Mailer: message header

After a long list of options below, you will find the function feedmail-send-it. Hers's the best way to use the stuff in this file:

Save this file as feedmail.el somewhere on your elisp loadpath; byte-compile it. Put the following lines in your init file:

    (setq send-mail-function 'feedmail-send-it)
    (autoload 'feedmail-send-it "feedmail")

If you plan to use the queue stuff, also use this:

    (setq feedmail-enable-queue t)
    (autoload 'feedmail-run-the-queue "feedmail")
    (autoload 'feedmail-run-the-queue-no-prompts "feedmail")
    (setq auto-mode-alist (cons '("\\\\.fqm$" . mail-mode) auto-mode-alist))

though VM users might find it more comfortable to use this instead of the above example's last line:

    (setq auto-mode-alist (cons '("\\\\.fqm$" . feedmail-vm-mail-mode) auto-mode-alist))

If you end up getting asked about killing modified buffers all the time you are probably being prompted from outside feedmail. You can probably get cured by doing the defadvice stuff described in the documentation for the variable feedmail-queue-buffer-file-name below.

If you are wondering how to send your messages to some SMTP server
(which is not really a feedmail-specific issue), you are probably
looking for smtpmail.el, and it is probably already present in your Emacs installation. Look at smtpmail.el for how to set that up, and then do this to hook it into feedmail:

    (autoload 'feedmail-buffer-to-smtpmail "feedmail" nil t)
    (setq feedmail-buffer-eating-function 'feedmail-buffer-to-smtpmail)

Alternatively, the FLIM <https://www.m17n.org/FLIM/> project provides a library called smtp.el. If you want to use that, the above lines would be:

    (autoload 'feedmail-buffer-to-smtp "feedmail" nil t)
    (setq feedmail-buffer-eating-function 'feedmail-buffer-to-smtp)

If you are using the desktop.el library to restore your sessions, you might like to add the suffix ".fqm" to the list of non-saved things via the variable desktop-files-not-to-save.

If you are planning to call feedmail-queue-reminder from your .emacs or something similar, you might need this:

    (autoload 'feedmail-queue-reminder "feedmail")

If you ever use rmail-resend and queue messages, you should do this:

    (setq feedmail-queue-alternative-mail-header-separator "")

If you want to automatically spell-check messages, but not when sending them from the queue, you could do something like this:

    (autoload 'feedmail-mail-send-hook-splitter "feedmail")
    (add-hook 'mail-send-hook 'feedmail-mail-send-hook-splitter)
    (add-hook 'feedmail-mail-send-hook 'ispell-message)

If you are using message-mode to compose and send mail, feedmail will probably work fine with that (someone else tested it and told me it worked). Follow the directions above, but make these adjustments instead:

    (setq message-send-mail-function 'feedmail-send-it)
    (add-hook 'message-mail-send-hook 'feedmail-mail-send-hook-splitter)

If you use message-mode and you make use of feedmail's queueing stuff, you might also like to adjust these variables to appropriate values for message-mode:

    feedmail-queue-runner-mode-setter
    feedmail-queue-runner-message-sender

If you are using the "cmail" email package, there is some built-in support for feedmail in recent versions. To enable it, you should:

    (setq cmail-use-feedmail t)

;;;;;;

I think the LCD is no longer being updated, but if it were, this would be a proper LCD record. There is an old version of feedmail.el in the LCD archive. It works but is missing a lot of features.
