Heavy duty browser for mail folders
Buffy is a program that displays a compact summary of your mail folders, and allows one to invoke a command (usually a mail reader) on them. It is written with the intent of being a handy everyday tool for people handling large volumes of mail. For mutt users, this can be a nice front-end to supplement the simple built-in folder browser when one has many folders to keep track of. . Buffy tries hard to work out of the box: it looks for mail folders in sensible places and comes with reasonable defaults. . The program is functional but still very young, and only Maildir and Mailbox format are supported at the moment.
