* :app email

This module makes Emacs an email client, using ~mu4e~.

#+begin_quote
I want to live in Emacs, but as we all know, living is incomplete without email. So I prayed to the text editor gods and they (I) answered. Emacs+evil's editing combined with org-mode for writing emails? /Yes please./

It uses ~mu4e~ to read my email, but depends on ~offlineimap~ (to sync my email via IMAP) and ~mu~ (to index my mail into a format ~mu4e~ can understand).

WARNING: my config is gmail/gsuite oriented, and since Google has its own opinions on the IMAP standard, it is unlikely to translate to other hosts.

** Install
This module requires:

+ ~offlineimap~ (to sync mail with)
+ ~mu~ (to index your downloaded messages)

*** MacOS
#+BEGIN_SRC sh :tangle (if (doom-system-os 'macos) "yes")
brew install mu --with-emacs
brew install offlineimap
#+END_SRC

*** Arch Linux
#+BEGIN_SRC sh :dir /sudo:: :tangle (if (doom-system-os 'arch) "yes")
sudo pacman --noconfirm --needed -S offlineimap mu
#+END_SRC

** Dependencies
You need to do the following:

1. Write a ~\~/.offlineimaprc~. Mine can be found [[https://github.com/hlissner/dotfiles/tree/master/shell/+mu][in my dotfiles repository]]. It is configured to download mail to ~\~/.mail~. I use unix pass to securely store my login credentials.
2. Download your email: ~offlineimap -o~ (may take a while)
3. Index it with mu: ~mu index --maildir ~/.mail~

Then configure Emacs to use your email address:

#+BEGIN_SRC emacs-lisp :tangle no
;; + %s is replaced with the label, e.g. /%s/Drafts => /lissner.net/Drafts
;; + Each path is relative to `+email-mu4e-mail-path', which is ~/.mail by
;;   default
(set! :email "lissner.net"
    '((mu4e-sent-folder       . "/%s/Sent Mail")
      (mu4e-drafts-folder     . "/%s/Drafts")
      (mu4e-trash-folder      . "/%s/Trash")
      (mu4e-refile-folder     . "/%s/All Mail")
      (smtpmail-smtp-user     . "henrik@lissner.net")
      (user-mail-address      . "henrik@lissner.net")
      (mu4e-compose-signature . "---\nHenrik Lissner"))
    t)
#+END_SRC
