Stalwart is a self-hosted email and collaboration infrastructure that provides an integrated mail server supporting SMTP, IMAP, POP3, and JMAP protocols. It functions as a comprehensive communication hub, combining email hosting with a collaboration server for shared calendars, contacts, and files. The system distinguishes itself through a distributed architecture that uses peer-to-peer cluster coordination to ensure high availability and fault tolerance. It features a built-in security suite that implements an S/MIME and OpenPGP email gateway alongside automated TLS certificate provisioning
Implements a secure mail system with built-in support for S/MIME and OpenPGP encryption.
This project is a software engineering style guide and a curated collection of architectural patterns and coding standards. It provides a multi-language coding standard to ensure maintainable software across Ruby, Python, JavaScript, and Swift. The project establishes a development workflow specification for version control, continuous integration, and peer review to maintain a linear project history. It also includes a web accessibility framework based on ARIA and WCAG standards, using design tokens and semantic HTML patterns to build inclusive interfaces. The guides cover a broad range of
Defines standards for using PGP and S/MIME to encrypt email content and verify sender identity.
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
Manages secure email transmission using standards for transparent or managed encryption.
This project is an email alias management platform and masking proxy designed to protect user privacy. It functions as a gateway that creates unique email addresses to hide a user's primary mailbox, forwarding incoming messages while routing outbound replies through a reverse-proxy to maintain sender anonymity. The system distinguishes itself through advanced domain and privacy controls, including the ability to link personal domains via DNS for branded aliases and catch-all routing. It further secures communications via a PGP encryption gateway that encrypts forwarded email content using pub
Operates a PGP encryption gateway that secures forwarded email content using public keys.
