maildir indexer/searcher + emacs mail client + guile bindings

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.

History

Mu was written an e-mail indexer/searcher in 2008. The author was using mutt, then Wanderlust and later, wondered if he could use mu as the backend for an emacs-based e-mail client. So the the first version of… mu4e was realized in 2012.

Note

Mu includes an emacs-based e-mail client (mu4e), a simple GUI (mug) and bindings for the Guile programming language.

Documentation

Documentation available for mu and mu4e.

mu

mu4e

Under the hood, mu4e is fully search-based, similar to programs like notmuch and sup.

However, mu4e’s user-interface is quite different. mu4e’s mail handling (deleting, moving etc.) is inspired by Wanderlust (another Emacs-based e-mail client), mutt and the dired file-manager for emacs.

mu4e keeps all the ‘state’ in your maildirs, so you can easily switch between clients, synchronize over IMAP, backup with rsync and so on. The Xapian-database that mu maintains is mererly a cache; if you delete it, you won’t lose any information.

What mu4e does not do

There are a number of things that mu4e does not do, by design:

  • mu/mu4e do not get your e-mail messages from a mail server. Nor does it sync-back any changes. Those tasks are delegated to other tools, such as offlineimap, isync/mbsync or fetchmail; As long as the messages end up in a maildir, mu4e and mu are happy to deal with them.
  • mu4e also does not implement sending of messages; instead, it depends on smtpmail, which is part of Emacs. In addition, mu4e piggybacks on Gnus’ message editor; See Message Manual.

Thus, many of the things an e-mail client traditionally needs to do, are delegated to other tools. This leaves mu4e to concentrate on what it does best: quickly finding the mails you are looking for, and handle them as efficiently as possible.
