Learn MoreUnlike any other solution on the market, Stalwart redefines the email server landscape. Traditionally, operating a mail server required piecing together multiple components—such as MTA, message store, and spam filter—each developed over 20 years ago with their own configuration formats. Stalwart streamlines this process into a single, efficient binary with a unified configuration. Furthermore, it is crafted in Rust, a language celebrated for its memory safety, ensuring a robust and secure email infrastructure.
