Email Configuration

Emacs can add iCalendar invites from email to an Org Mode file and heading of your choice. The functions to add iCalendar invites can be found in gnus-icalendar. These same functions are called from Mu4e but they are found in the Gnus package so we must set them up there.

(use-package gnus
  :straight (:type built-in)
  :defer t
  :hook
  (dired-mode . turn-on-gnus-dired-mode)
  :custom
  (gnus-icalendar-org-capture-file "~/Dropbox/gtd/inbox.org")
  (gnus-icalendar-org-capture-headline '("Calendar"))
  :config
  (require 'gnus-icalendar)
  (gnus-icalendar-setup)
  (gnus-icalendar-org-setup))

Mu4e is a package that used the Mu indexer to search through emails that are saved to the local system in the Maildir format.

(use-package mu4e
  :defer t
  :preface
  (setq mail-user-agent 'mu4e-user-agent)
  (setq read-mail-command 'mu4e)
  :custom
  (mu4e-maildir (expand-file-name "~/Mail"))
  (mu4e-get-mail-command "mbsync -c ~/.emacs.d/mu4e/.mbsyncrc -a")
  (mu4e-view-prefer-html t)
  (mu4e-view-show-images t)
  (mu4e-update-interval 300)
  (mu4e-headers-auto-update t)
  (mu4e-compose-signature-auto-include t)
  (mu4e-compose-format-flowed t)
  (mu4e-compose-in-new-frame t)
  (mu4e-sent-messages-behavior 'delete)
  (mu4e-attachment-dir  "~/Downloads")
  (mu4e-change-filenames-when-moving t)
  (message-kill-buffer-on-exit t)
  (mu4e-compose-dont-reply-to-self t)
  :config
  (require 'mu4e-icalendar)
  (mu4e-icalendar-setup)
  (setq mu4e-org-contacts-file  "~/Dropbox/contacts.org")
   (add-to-list 'mu4e-headers-actions
     '("org-contact-add" . mu4e-action-add-org-contact) t)
   (add-to-list 'mu4e-view-actions
     '("org-contact-add" . mu4e-action-add-org-contact) t)
  (load "~/.emacs.d/mu4e/mu4e-contexts.el")
  (require 'mu4e-speedbar)
  ;; Add option to view emails in browser
  (add-to-list 'mu4e-view-actions
               '("ViewInBrowser" . mu4e-action-view-in-browser) t))

Set the Maildir top-level directory.

(mu4e-maildir (expand-file-name "~/Mail"))

Tell mu4e to use mbsync to get email from the server and synchronize email back to the fto server. Other programs that may work for this purpose include offlineimap and fetchmail.

(mu4e-get-mail-command "mbsync -c ~/.emacs.d/mu4e/.mbsyncrc -a")

Tell mu4e to prefer using HTMxsL email as most email these days are sent in this format and tell Mu4e to show images inline in the email message buffers.

(mu4e-view-prefer-html t)
(mu4e-view-show-images t)

Add support for accepting iCalendar invites by email with Mu4e:

(require 'mu4e-icalendar)
(mu4e-icalendar-setup)

Org-contrib has library org-contacts that can be used to store contact information in an Org Mode file. This file is a little easier to read than using a tool such as BBDB as it can be read and understood easilty with any plain text editor.

First, org-contacs must be required from the org-contrib package and the default contacts file must be defined.

(require 'org-contacts)
(setq org-contacts-files '("~/Dropbox/contacts.org"))

Then, we can integrate org-contacts with mu4e by additng it to the mu4e-headers-actin and the mu4e-view-actions so that the key combination a o can be used to add an email address to the file containing our contacts.

(setq mu4e-org-contacts-file  "~/Dropbox/contacts.org")
 (add-to-list 'mu4e-headers-actions
   '("org-contact-add" . mu4e-action-add-org-contact) t)
 (add-to-list 'mu4e-view-actions
   '("org-contact-add" . mu4e-action-add-org-contact) t)

Org Mime is a tool that can be used to convert an email written in Org Mode format to be converted to HTML before sending so that email readers can render the email in HTML format. It works by having the user write the whole email using Org Mode syntax followed by execution of the command org-mime-htmlize prior to sending the email.

(use-package org-mime
  :straight t
  :commands (org-mime-htmlize
             org-mime-org-buffer-htmlize
             org-mime-org-subtree-htmlize))

Tell Emacs what feature this file provides.

(provide 'freemacs-email)
