nmzmail is a tool to use the namazu2 search engine from within the mutt mail reader to search mail stored in maildir folders. Based on the result of the namazu query, nmzmail generates a maildir folder containing symbolic links to the mails matching the query.
Here are some key features of "nmzmail":
· fast mail searching even with large number of mails; I use it currently on about 10000 emails
· incremental index building
· rich query language including regular expressions (see the namazu documentation)
· integrates nicely into mutt
· query history
