# Welcome to mu!
|
||
|
||
<img src="mu.jpg" align="right" margin="10px"/> 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](http://en.wikipedia.org/wiki/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](cheatsheet.html) for some
|
||
examples. Mu's source code is available [in github](https://github.com/djcb/mu), and there is the
|
||
[mu-discuss](http://groups.google.com/group/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.
|
||
|
||
## Features
|
||
|
||
- fast indexing for [Maildir](http://en.wikipedia.org/wiki/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](http://www.mutt.org/) and
|
||
[Wanderlust](http://www.emacswiki.org/emacs/WanderLust).
|
||
- [mu4e](mu4e.html), an emacs-based e-mail client based on `mu` (see screenshot).
|
||
- [mu-guile](mu-guile.html):
|
||
[guile 2.0](http://www.gnu.org/software/guile/) bindings that
|
||
allow for scripting, advanced processing of your data, and doing
|
||
all kinds of statistics
|
||
- fully documented (man pages, info pages)

### 2016-12-05: mu/mu4e 0.9.18 is available
|
||
|
||
mu 0.9.18 offers a number of improvements across the board. For
|

example, people with huge maildirs can use a special "lazy-checking"
|
||
mode to speed up indexing; it's now possible to view rich-text message
|

in an embedded webkit-view, and the release adds support for org-mode
|
||
9.x. There also many small fixes and tweaks in mu4e, all based on

|
||
|
||
#### Better behaviour and context handling
|
||
- Context Handling just got smart: new ‘mu4e-context’ defines and switches between various contexts, which are groups of settings. This may be used for instance to easily configure and switch between multiple accounts.
|
||
- Improved behaviour in html and messages marks: ability to toggle between html and text display of messages & better management of messages marked as read or unread.
|
||
|
||
#### User Interface improvements
|
||
- Numerous improvements in threads view and mailing lists management
|
||
- Fancy characters can now be properly used as well as special customizations for message views
|
||
|
||
#### Faster Indexing and message management
|
||
- Indexing & caching optimizations
|
||
|
||
You can grab the tarball directly
|
||
[from Github](https://github.com/djcb/mu-releases) or wait a bit to
|
||
get it through your distribution channels (details may vary from one
|
||
distribution to another).
