Stalwart ships first stable release, v1.0

Stalwart released its first stable version, v1.0, according to a report on the Hacker News front page on October 26, 2026. The project has been in development for five years. It began as mail-parser, a Rust mail parsing library, and grew into a full mail and collaboration server supporting JMAP, IMAP, SMTP and other protocols. The release marks the first stable version since that shift from parsing library to multi-protocol server. The report describes it as "the world's fastest mail server," but the provided material lists no performance test results or comparison basis.
