Hi,

Using the attached file it is possible to compose mail using org-mode
(orgstruct, and orgtbl modes to be specific), and then send the mail
as a "text/html" mime message.  In effect WYSWYG html email
composition.  I find this very useful for sending lists and tables to
co-workers who use non-fixed-width-font email clients.

I put this together with the help of Rob form the gnu.emacs.vm.info
newsgroup, and I use it with VM, but it no-where mentions VM, and it
*should* work with any emacs email composition buffer.

To use place the attached file in your path, and add the following to
you .emacs file

;; org-mode in my mail
(setq mail-turn-on-full-org-mailing-first-time t)
(defun turn-on-full-org-mailing ()
  (if mail-turn-on-full-org-mailing-first-time
      (progn
        (org-publish (car (car org-publish-project-alist)))
        (setq mail-turn-on-full-org-mailing-first-time nil)))
  ;;(turn-on-orgstruct)
  (turn-on-orgstruct++)
  (turn-on-orgtbl)
  (load "org-html-mail.el"))
(add-hook 'mail-mode-hook 'turn-on-full-org-mailing)

Then when composing mail send as an html message by using a prefix
argument on the send command, so "\C-u\C-c\C-c".  Your mail will be
converted to html using org's export command, the appropriate mime
headers will be attached, and then your normal send command will be
executed.

Note: This is still very young, so here are some issues, and ideas for
improvement that the list may be able to help with. :)

1. it seems that for the org-export-as-html command to work, the
   buffer must be associated with a file, this adds some complexity to
   the process, is it possible to export-as-html without associating
   the buffer with a path?
2. if org-export-as-html has not yet been called since turning emacs
   on, then the following error occurs in org-export-as-html
	------*Messages*-------
	Exporting... [2 times]
	byte-code: Wrong type argument: stringp, nil
	------*Messages*-------
   Hence they hacky turn-on-full-org-mailing function, and
   mail-turn-on-full-org-mailing-first-time variable
3. I would like to add the feature of automatically attaching, and
   linking to images from the html, but I haven't really started this,
   and I'm not sure how it would work, so any thoughts would be
   appreciated.

Thanks,
Eric
