**** Basic configuration
As seen below, I use ~org-msg~ to compose my emails, which includes by
default my signature. Therefore, there is no need for Emacs itself to
know about it since I dont want it to include it a second time after
~org-msg~ already did.

**** Mu4e
Mu4e is a very eye-pleasing email client for Emacs, built around ~mu~
and which works very well with ~mbsync~ (found in Archs ~isync~ package).
For me, the main advantage of mu4e is it has a modern interface for
emailing, and quite straightforward. I tried a couple of other email
clients for Emacs, and I even was for some time a Gnus user, but in
the end, mu4e really works best for me. Below youll find my
configuration for the ~mu4e~ package itself.
Quick sidenote: on ArchLinux, youll need to install either ~mu~ or
~mu-git~ from the AUR in order to use mu4e.

***** Bookmarks
In mu4e, the main focus isnt really mail directories such as your
inbox, your sent messages and such, but instead you manipulate
bookmarks which will show you emails depending on tags. This mean you
can create some pretty customized bookmarks that go way beyound your
simple inbox, outbox and all. Actually, four of my bookmarks have a
couple of filtering:
- anything in my inbox linked to my university
- the [[https://emacs-doctor.com/lists/listinfo][emacs-doctor mailing list]] (French Emacs mailing list)
- the conlang mailing lists
- and my inbox for any mail not caught by any of these filters
And all of them will have the requirement not to display any trashed
email. Actually, all of my bookmarks will have this requirement,
except for the bookmark dedicated to them as well as my sent emails.
Ill add these latter requirements later.
Here are the requirements for my university bookmark. The regex
matches any email address which contains either ~up8.edu~ or
~univ-paris8~, which can be found in email addresses from the University
Paris 8 (my university).

As for the Emacs-doctor list, I need to match both the current, modern
mailing list address but also its old address.

When it comes to the conlang mailing list, lets not match anything
from or to them. Ill also include the auxlang mailing list Im not
subscribed anymore, but itll keep my inbox clean.

As I said earlier, something that will often come back in my bookmarks
is the emails must not be trashed to appear. I want also to display
junk emails, so I end up with the following rule:
#+name: mu4e-bookmarks-default-filter
#+headers: :tangle no :exports both :cache yes
#+begin_src emacs-lisp
(string-join `("NOT flag:trashed"
,(format "(%s)" (mapconcat (lambda (maildir) (concat "maildir:" maildir))

And for the last string-generating code, lets describe my main inbox:
#+name: mu4e-bookmarks-inbox-filters
#+headers: :exports both :tangle no :cache yes
#+begin_src emacs-lisp
(string-join (cons

Now, lets define some keybindings for mu4es view mode, that is when
we are viewing an email. All these keybindings will reside between the
major-mode specific leader key ~,~ and most of these keybindings can be
described with a simple function:
#+name: mu4e-keybindings-view-tbl
| Keybinding | Function | Description |
|------------+--------------------------------------+--------------------|

Some functions are however lambdas. They all are written as actions on
the current thread. They all begin with ~,t~, and below you can see each
one of the possible following key can act on a thread:

Some simple keybindings are defined for mu4es header mode:
#+name: mu4e-keybindings-headers-tbl
| Key | Function | Description |
|-----+----------+-------------|
| s | swiper | |
| t | nil | thread |
The keybindings from table [[mu4e-keybindings-view-lambdas-tbl]] will also
be reused for this mode.

#+end_src
#+RESULTS: mu4e-keybindings-header
I will also redefine without a leader key ~ctsr~ in order to be able to
move freely (remember, bépo layout for me).

Finally, lets declare a couple of keybindings for when we are
composing a message. This time, all my keybindings are prefixed with
the major-mode leader and call a simple function.
