Keeping on the theme of Emacs today, let's talk about email in Emacs. There are
various options out there, but you're most likely to come across people talking
about Gnus, Wanderlust, Notmuch, and mu4e. I've ended up with the latter, after
trying the others (and also experimenting with mutt a few times). mu4e is pretty
easy to use, and powerful. It sits on top of the
mu command line tool that will
index and deal with mail that's in the Maildir format on a local machine.
As with most things in Emacs you probably should take a look at different options to see what fits you best. I found that mu4e was just simpler for the way I use email.
On starting up mu4e with
M-x mu4e (bound to
Spc a M for me) you'll be greeted
with this home screen.
If you *J*ump into a Maildir, search, or use the bookmarks then you'll enter the index view and mail you open from thre displays in a lower pane. Here I did a *s*earch for 'emacs' and opened up a mail:
Mu4e also does a half decent job of showing HTML email in an intelligible way with w3m.
Getting email down to mu
My main email account is hosted with Zoho. To sync that down to a Maildir on my
computer so that
mu can index it I'm using isync. I have an
.mbsyncrc in my
that is configured to pull down from Zoho over IMAP:
Create Both Expunge Both SyncState * IMAPAccount zoho Host imappro.zoho.com User xxxxxxxxxxxxxxxxx SSLType IMAPS CertificateFile /etc/ssl/certs/ca-bundle.crt IMAPStore zoho-remote Account zoho MaildirStore zoho-local Subfolders Verbatim Path ~/Mail/ Inbox ~/Mail/INBOX Channel zoho Master :zoho-remote: Slave :zoho-local: Patterns *
mkdir ~~/Mail && mbsync -a will get the Maildir setup properly the first
time. In future we can have mu4e call that from within emacs to update things.
Once the Maildir is in place it needs to be initially indexed with mu. This is
pretty painless once you have mu installed. Because mu is such a short name, the
package is likely called
maildir-utils in your distro. Once you have that installed
mu init --maildir=~/Mail --email@example.com
Add as many
--my-address options as you need to cover all of the email addresses
that you use.
I'm running Emacs with a config that is based on something I originally found on GitHub, which has now been archived by the original creator. It has spacemacs type keybindings, but is much less comprehensive / complicated.
The config I have to use mu4e is fairly straightforward. First we setup some of the keybindings specific to the spacelite thing I am using.
(defun spacelite/init-mail () (use-package mu4e :ensure nil :commands mu4e :init (spacelite/set-leader-keys "a M" 'mu4e) (global-set-key (kbd "C-x m") 'mu4e-compose-new) (spacelite/set-leader-keys-for-major-mode 'mu4e-compose-mode "c" 'message-send-and-exit "k" 'message-kill-buffer "a" 'message-kill-buffer "s" 'message-dont-send ; saves as draft "f" 'mml-attach-file)
remove-hook is important to avoid a bug that affects
newer versions of mu.
:config (remove-hook 'mu4e-main-mode-hook 'evil-collection-mu4e-update-main-view)
Next set some nice-to-haves. Easy access to view in a browser, use fancy UTF characters for check marks etc, show images in mail, download locations.
(add-to-list 'mu4e-view-actions '("View in browser" . mu4e-action-view-in-browser) t) (setq mu4e-completing-read-function 'completing-read mu4e-use-fancy-chars 't mu4e-view-show-images 't message-kill-buffer-on-exit 't) (let ((dir "~/Downloads")) (when (file-directory-p dir) (setq mu4e-attachment-dir dir)))
Now we setup the location of my Maildir, and the names of the common folders… which often vary between providers and may depend on what other clients you might use.
Note that the
mu4e-get-mail-command is set to call
mbsync -a, which is what I
setup previously to fetch my mail from Zoho via IMAP.
;;; Set up some common mu4e variables (setq mu4e-maildir "~/Mail" mu4e-sent-folder "/Sent Mail" mu4e-drafts-folder "/Drafts" mu4e-trash-folder "/Trash" mu4e-refile-folder "/Archive" mu4e-get-mail-command "mbsync -a" mu4e-update-interval nil mu4e-compose-signature-auto-include nil mu4e-view-show-addresses t)
On the sending side of things we have to give the SMTP server details.
;;; Email sending settings (setq user-mail-address "xxxxxxxxxxx" smtpmail-default-smtp-server "smtp.zoho.com" smtpmail-smtp-server "smtp.zoho.com" smtpmail-smtp-user "xxxxxxxxxx" smtpmail-smtp-service 587)
Now we configure shortcuts and bookmarks to access the most useful mail
directories, or searches. These were just taken right from a guide on the web
I've lost - and I've not felt the need to customize them yet. Note how the
bookmarks specify searches, not locations.
mu is all about searching email, and
then working on views of these search results.
;;; Mail directory shortcuts (setq mu4e-maildir-shortcuts '(("/INBOX" . ?z))) ;;; Bookmarks (setq mu4e-bookmarks `(("flag:unread AND NOT flag:trashed" "Unread messages" ?u) ("date:today..now" "Today's messages" ?t) ("date:7d..now" "Last 7 days" ?w) ("mime:image/*" "Messages with images" ?p) (,(mapconcat 'identity (mapcar (lambda (maildir) (concat "maildir:" (car maildir))) mu4e-maildir-shortcuts) " OR ") "All inboxes" ?i)))
Finally, this setting will send any notifications from mu to the Messages buffer
by default. You can change this to use libnotify or similar to get desktop
notifications. I have
mu4e-update-interval nil though, so it's not really
interesting here. I check my email manually when I want to, so notifications
aren't really a consideration.
(setq mu4e-enable-notifications t))) (provide 'spacelite-mail)
And that's it. I use mu4e for most of my email activities now. It has stuck in a way that previous flirtations with mutt, and the other Emacs approaches, haven't. It's simple and very effective.
