Mailpile is an encrypted email client and high-volume mail indexer that provides a web-based portal for managing electronic mail. It functions as a private email management system designed to protect user privacy and data control.
The project features a search engine optimized for indexing and retrieving large volumes of email on consumer hardware. It includes a Bayesian email filter for automated message classification and tagging.
The system supports secure communication through the integration of public-key encryption and signing for sending and receiving messages. Additional capabilities include rule-based message routing and access via command-line tools.
