    Mailpile's primary user interface is web-based, but it also has a basic command-line interface and an API for developers. Using web technology for the interface allows Mailpile to function both as a local desktop application (accessed by visiting localhost in the browser) or a remote web-mail on a personal server or VPS.

    The core of Mailpile is a fast search engine, custom written to deal with large volumes of e-mail on consumer hardware. The search engine allows e-mail to be organized using tags (similar to Gmail's labels) and the application can be configured to automatically tag incoming mail either based on static rules or bayesian classifiers.
