mairix

indexes and searches locally-stored email

mairix is a program for indexing and searching email messages stored offline on your computer. mairix supports the Maildir, MH folders, and mbox formats. Some features: * Indexing is fast. It runs incrementally on new messages - any particular message only gets scanned once in the lifetime of the index file. * Searching is fast. * The search mode populates a "virtual" maildir folder with symlinks which point to the real messages. This folder can be opened as usual in your mail program. * Indexing and searching is based on words. The index file tabulates which words occur in which parts (particular headers + body) of which messages.
