I want to use at one point the [[https://www.emacswiki.org/emacs/EmacsApplicationFramework][Emacs Application Framework]] which is set to
be able one day to render Gnus emails, but for now I am using w3m to render
HTML emails I receive.
#+BEGIN_SRC emacs-lisp
(setq mm-text-html-renderer 'w3m)
#+END_SRC
I also want Gnus to use the cache in case I need to navigate my emails
offline:
#+BEGIN_SRC emacs-lisp
(setq gnus-use-cache t)
#+END_SRC
The following allows the user to read in a group all the messages in this
group, whether they are read or unread.
#+BEGIN_SRC emacs-lisp
(setq gnus-fetch-old-headers t)
(setq gnus-parameters '(("nnimap.*"

#+END_SRC
Let’s set a quick organization of the Gnus folders, the format in which sent
messages should be saved, and the typology of Gnus’ topics:

I get it that it used to be a good option with 4/3 screens, but frankly
opening an email at the bottom of the frame instead of the side of the frame
does not look good anymore. So, let’s fix that:

Mu4e is a frontend for mu, an email analyzer which sits on top of a Maildir
which gets updated with ~isync~. It has a lot of neat features, but I guess
my favorite ones are:
1. the search query feature
2. being able to send an HTML email either to the browser or
3. to compile it to a PDF for a better output
This last feature can only be enabled manually with Arch Linux. We need
~webkitgtk~ installed, and unfortunately, it is by default only available
through the AUR and has to be compiled. Thing is, ~webkitgtk~ is a *BIG*
piece of software, and compiling it can be very time consuming. So, I decided
to add ArchLinuxCN’s servers to my pacman config (instructions on how to do
so [[https://github.com/archlinuxcn/repo][here]]) so I could install a compiled version from their repos. Next, when I
installed ~mu~ from the AUR, I modified the PKGBUILD like so:
#+BEGIN_SRC diff :tangle no
< ./configure --prefix=/usr --disable-webkit --disable-gtk --enable-mu4e --enable-guile
---
> ./configure --prefix=/usr --enable-mu4e --enable-guile
#+END_SRC
This enables the installation of ~msg2pdf~, which in turn enables the email
compilation to PDF with the shortcut ~a v~ when an email is opened, and this
opens the PDF in a new Emacs buffer.
Due to mu sitting on top of a Maildir, I need to tell mu4e where said maildir
is, and point it the trash, archive, and sent folders as well as the refresh
command and how frequently I want my emails to be refreshed.
#+BEGIN_SRC emacs-lisp
(setq mu4e-maildir "~/.mail"
mu4e-trash-folder "/Trash"
mu4e-refile-folder "/Archive"
mu4e-sent-folder "/Sent"
mu4e-get-mail-command "mbsync -a"
mu4e-update-interval 60
mu4e-compose-signature-auto-include t
mu4e-update-interval 60)
#+END_SRC
The following also allows me to automatically include my signature in my
Emails, to view images in my Emacs buffers and to show me the address of my
contacts and not just their names.
#+BEGIN_SRC emacs-lisp
(setq mu4e-compose-signature-auto-include t
mu4e-view-show-images t
mu4e-view-show-addresses t)
#+END_SRC
Bookmarks
This source block is an example of the search queries in mu4e, and part of
the reason why I very much like mu4e: these bookmarks are actually defined by
search queries, but act as if they were just yet another type of custom inbox
you get with modern Email client (and often you don’t even get them). All
these bookmarks can be accessed through a shortcut on the main mu4e buffer,
prefixed by ~b~. So, for instance, my unread messages are accessed through
~bu~.
#+BEGIN_SRC emacs-lisp
(setq mu4e-bookmarks
`(("flag:unread AND NOT flag:trashed" "Unread messages" ?u)

#+END_SRC
Enable OS notifications.
On new email arrival, Emacs can send the system a notification which will be
handled as any other notification received by the system and will display the
number of unread emails to the user; in my case, notifications are handled by
[[https://dunst-project.org/][dunst]].
#+BEGIN_SRC emacs-lisp
(setq mu4e-enable-notifications t)
(setq mu4e-enable-notifications t
mu4e-alert-email-notification-types '(count))

Now this hook is added so I can get a maximal width for the text of my
emails, I really don’t like it when lines are kilometers long. I would like
instead to hook ~visual-line-mode~ and ~auto-fill-mode~, but for some reasons
Emacs throws an error when I add them, So I go with ~visual-fill-column-mode~
instead.
#+BEGIN_SRC emacs-lisp
(add-hook 'mu4e-view-mode-hook 'visual-fill-column-mode)
#+END_SRC
Vertical split
On modern-day computers, with wide screens almost everywhere, there is no
reason for the email buffer to open below the email directory and not on its
right, which is why I set the split view to be vertical instead of
horizontal. I also set the width the email directory should keep to 80
characters (and I could go to 120, but that’s only good for my
ultra-widescreen), because 30 characters is way too f-ing low.
#+BEGIN_SRC emacs-lisp
(setq mu4e-split-view 'vertical
mu4e-headers-visible-columns 80)
#+END_SRC
I want to add myself as a hidden recipient to all of my messages so I can get
them in the email thread in my inbox and not just get a thread of messages
not sent by me –the thread could kinda lack some context if the other people
do not insert my email in their answer. But unfortunately, for some obscure
reason, mu4e does not use the following variable for its email templates, so
I am keeping this as a reminder I should find how to fix that. It does work
when I’m exporting an org file to and HTML buffer to be sent by email through
~, e m~.
#+BEGIN_SRC emacs-lisp
(setq message-default-headers "Bcc: Lucien Cartier-Tilet <lucien@phundrak.com>\n")
#+END_SRC
Finally but very importantly, this is the setup I have for my SMTP mail
server: I point Emacs’ SMTP services to my private mail server on its SMTP
port, which should be used with a STARTTLS stream. And I tell Emacs this is
the default way to send an email.
#+BEGIN_SRC emacs-lisp
(setq smtpmail-smtp-server "mail.phundrak.com"
smtpmail-smtp-service 587
smtpmail-stream-type 'starttls
message-send-mail-function 'smtpmail-send-it)
#+END_SRC
I am unsure yet if this has any effect on mu4e, but this variable should
discourage mu4e from reading rich text emails and instead open them as plain
text. However, I do not wish to discourage opening HTML emails since I can
compile them to PDF or open them in the browser.
#+BEGIN_SRC emacs-lisp
(setq mm-discouraged-alternatives '("text/richtext"))
#+END_SRC
I am still unsure about this variable and if it has an effect on mu4e, but I
wish to set a default web viewer for my HTML emails: w3m. This is not as
effective as sending the email in the browser or rendering it as a PDF file,
but it can be effective enough for some emails.
#+BEGIN_SRC emacs-lisp
(setq mm-text-html-renderer 'w3m)
#+END_SRC
