Description
Notmuch is not much of an email program. It doesn't receive messages
(no POP or IMAP suport). 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 is still in the early stages of development, but it does
include one user interface, (implemented within emacs), which has at
least two users using it for reading all of their incoming mail. If
you've been looking for a fast, global-search and tag-based email
reader to use within emacs, then Notmuch may be exactly what you've
been looking for.
Otherwise, 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, then Notmuch also may be exactly what
you've been looking for.
