Indexing and searching in Maildir, MH, or mbox folders
Mairix is a program for indexing and searching email messages stored in Maildir, MH or mbox folders.
- Indexing is fast. It runs incrementally on new messages - any particular message only gets scanned once in the lifetime of the index file.
- The search mode populates a “virtual” folder with symlinks* which point to the real messages. This folder can be opened as usual in your mail program.
- The search mode is very fast.
- Indexing and searching works on the basis of words. The index file tabulates which words occur in which parts particular headers + body of which messages.
