;;; mail-config --- Settings for Mu4e Email -*- lexical-binding: t; -*-
;; author Craig Jennings <c@cjennings.net>
;;; Commentary:
;; I found Aime Bertrand's blog post to be an excellent walkthrough of how to
;; setup a Mu4e config.
;; https://macowners.club/posts/email-emacs-mu4e-macos/
;;; Code:
(use-package mu4e
:ensure nil ;; mu4e gets installed by installing 'mu' via the system package manager
:load-path "/usr/share/emacs/site-lisp/mu4e/"
:defer .5
:bind

(:map mu4e-view-mode-map

:config
(setq gnus-blocked-images "http") ;; block external images
(setq mail-user-agent 'mu4e-user-agent) ;; default to mu4e for email
(setq message-citation-line-format "On %a %d %b %Y at %R, %f wrote:\n") ;; helps show up properly in Outlook/Gmail threads
