It was a great day for me when I finally got mu4e working and moved my email into Emacs. Emacsers who want to live in Emacs as much as possible will sooner or later look for a way of handling email from within their editor. I love mu4e and have no plans on trying something new but, of course, not everyone agrees and it is, after all, Emacs so there are lots of possible solutions.
One such solution is Wanderlust. It’s the email client that DJCB, the author of mu and mu4e, used before he wrote his own client. If you’re looking for an Emacs mail client and mu4e doesn’t fit your needs, you should definitely give Wanderlust a look. The Emacs Wiki has a page on Wanderlust with links to screenshots and other information.
Ahmed Khanzada has a useful post that explains how to configure Wanderlust. It’s actually easier than getting mbsync configured to work with mu4e. Khanzada’s post also explains how to get it to authenticate with Gmail. That’s a bit tricky so if you want to use Wanderlust and you’re a Gmail user, you should definitely check out his write-up.
