mu is a set of command-line tools for indexing and searching email stored in the Maildir format on Unix-like systems. It also includes mu4e, an Emacs-based email client, and Guile/Scheme bindings for scripting.
Use cases
- instantly find that one important email in a large maildir
- index and search maildir email from the command line
- read and manage email inside Emacs with mu4e
- extract attachments from email messages
- search messages by sender, date, size, flags, or attachments
- script email handling with Guile/Scheme
When to avoid
- you need a graphical email client
- your mail lives on a proprietary server without local Maildir access
- you need Windows-native support
