I second the suggestion of maildir-utils/mu[1]. Here's my setup for that, in case anyone is interested: https://gist.github.com/45e318c68eb5a52e1646 https://gist.github.com/45e318c68eb5a52e1646. It's essentially a cronjob (LaunchAgent on OSX) that calls a shell script to update the index periodically, plus a few macros to make searching from within mutt easier. To use this, you'll need to create a "Search" folder for maildir-utils to store results in. [1] http://www.djcbsoftware.nl/code/mu/ http://www.djcbsoftware.nl/code/mu/
