Welcome to mu!
Given the enormous amounts of e-mail many people gather and the importance of e-mail message in our work-flows, it’s essential to quickly deal with all that mail - in particular, to instantly find that one important e-mail you need right now.
mu is a tool for dealing with e-mail messages stored in the Maildir-format. mu’s main purpose is to help you to quickly find the messages you need; in addition, it allows you to view messages, extract attachments, create new maildirs, … See the mu cheatsheet for some examples.
Searching works by first indexing your messages into a Xapian-database, which can then be queried using a custom query language.

new features and fixes, many based on user suggestions.
munow supports mail threading based on the JWZ-algorithm; output is now automatically converted to the user-locale;
mu viewcan output separators between messages for easier processing, support for X-Label-tags, and last but not least,
