See below for a list of additional features, including the +;;; ability to queue messages for later sending. If you are using +;;; fakemail as a subprocess, you can switch to feedmail and eliminate +;;; the use of fakemail. feedmail works with recent versions of +;;; GNUemacs (mostly, but not exclusively, tested against 19.34 on +;;; Win95; some testing on 20.x) and XEmacs (tested with 20.4 and +;;; later betas). It probably no longer works with GNUemacs v18, +;;; though I haven't tried that in a long time. Sorry, no manual yet +;;; in this release. Look for one with the next release. + +;; 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. + +;; Author: Bill Carpenter , +;; Version: 8 +;; Keywords: email, queue, mail, sendmail, message, spray, smtp, draft +;; Where: +;; 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. + +;;; Commentary: +;; +;; 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. +;; +;; 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 everthing else. For info about custom, see +;; . +;; +;; 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 still use "fakemail", +;; or 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.
