Welcome to mu!
With the enormous amounts of e-mail many people gather and the importance of e-mail messages in our daily work-flow, it is very important to be able to quickly deal with all that - in particular, to instantly find that one important e-mail you need right now.
For that, mu was created. mu is a tool for dealing with e-mail messages stored in the Maildir-format, on Unix-like systems. mu’s main purpose is to help you to find the messages you need, quickly; in addition, it allows you to view messages, extract attachments, create new maildirs, … See the mu cheatsheet for some examples. Mu’s source code is available in github, and there is the mu-discuss mailing list.
mu includes an emacs-based e-mail client (
mu4e), a simple GUI
mug) and bindings for the Guile/Scheme programming language.
- fast indexing for Maildir, Maildir+ and Maildir-on-VFAT
- search for messages based on the sender, receiver, subject, date-range, size, priority, words in message, flags (signed, encrypted, new, replied, has-attachment,…), message-id, maildir, tags, attachment (name, mime-type, text) and more
- support for encrypted and signed messages
- command-line tools for indexing, searching, viewing, adding/removing messages, extracting attachments, exporting/searching address lists, creating maildirs, …
- accent/case normalization - so angstrom matches Ångström
- can be integrated with other e-mail clients such as mutt and Wanderlust.
mu4e, an emacs-based e-mail client based on
- mu-guile: guile 2.0 bindings that allow for scripting, advanced processing of your data, and doing all kinds of statistics
- fully documented (man pages, info pages)
2015-09-24: After almost 6 months, a new release of mu/mu4e. We are happy to announce mu and mu4e 0.9.9.13! have just been released. The following key features and improvements have been added:
- Change the way the headers are displayed and sorted
- Fancy characters now enabled distinctively both for marks and headers
- Composing a message is now possible in a separate frame
- Ability to display the subject of a thread only on top of it for enhanced clarity
- Lots of bugs squashed, updates to the documentation (BDDB), as well as embedding the News file inside mu4e itself.
You may grab the the tarball from GitHub or get it through your distribution channels (details may vary from one distribution to another).
None of this would be possible without a team of dedicated individuals: Attila, Charles-H.Schulz, David C Sterrat, Dirk-Jan C. Binnema, Eike Kettner, Florian Lindner, Foivos S. Zakkak, Gour, KOMURA Takaaki, Pan Jie, Phil Hagelberg, thdox, Tiago Saboga, Titus von der Malsburg (and of course all people who reported issues, provided suggestions etc.)
We hope you will enjoy this release as much as we do. Happy Hacking!
