If you've been looking for a fast, global-search and tag-based email system to use within your text editor or in a terminal...
If you're the kind of person that gets excited about being able to write shell scripts for exploring and manipulating your email...
If you're a developer of an existing email program and would love a good library interface for fast, global search with support for arbitrary tags...
If you want the convenience of fast, reliable search of all your email, but don't want to give a 3rd-party access to your email...
Then notmuch may be exactly what you've been looking for.
"Not much mail" is what Notmuch thinks about your email collection. Even if you receive 12000 messages per month or have on the order of millions of messages that you've been saving for decades. Regardless, Notmuch will be able to quickly search all of it. It's just plain not much mail.
"Not much mail" is also what you should have in your inbox at any time. Notmuch gives you what you need, (tags and fast search), so that you can keep your inbox tamed and focus on what really matters in your life, (which is surely not email).
Notmuch is an answer to Sup. Sup is a very good email program written by William Morgan (and others) and is the direct inspiration for Notmuch. Notmuch began as an effort to rewrite performance-critical pieces of Sup in C rather than Ruby. From there, it grew into a separate project. One significant contribution Notmuch makes compared to Sup is the separation of the indexer/searcher from the user interface. (Notmuch provides a library interface so that its indexing/searching/tagging features can be integrated into any email program.)
Notmuch is not much of an email program. It doesn't receive messages (no POP or IMAP support). It doesn't send messages (no mail composer, no network code at all). And for what it does do (email search) that work is provided by an external library, Xapian. So if Notmuch provides no user interface and Xapian does all the heavy lifting, then what's left here? Not much.
Notmuch news (mostly release notes and changes).
To get started with Notmuch, just run "notmuch" at the command line. This command will walk you through initial setup, including specifying the location of your mail store and how to start the initial indexing.
