mu is a tool for dealing with e-mail messages stored in the Maildir-format. mu’s purpose in life is to help you to quickly find the messages you need; in addition, it allows you to view messages, extract attachments, create new maildirs, and so on.
Built on top of mu are some extensions, including mu4e, which is a full-featured e-mail client that runs inside Emacs. mu4e is designed to enable super-efficient handling of e-mail; searching, reading, replying, moving, and deleting.
mu4e keeps all the ‘state’ in your maildirs, so you can easily switch between clients, synchronize over IMAP, backup with rsync and so on.
Features include:
- Fully search-based: even if you ‘jump to a folder’, you are executing a query for messages that happen to have the property of being in a certain folder.
- Dynamic folders.
- UI optimized for speed with quick key strokes for common actions.
- Fully documented, with example configurations.
- Asynchronous: heavy actions never block emacs.
- Write rich-text e-mails using /org-mode/ (experimental).
- Address auto-completion based on your messages – no need for managing address books.
- Split view – see the Headers view and the Message view next to each other, with the message selected in the former, visible in the latter.
- Extendable in many places using custom actions. Write your own emacs-lisp to make mu4e behave exactly as you want.
