ACME (Automatic Certificate Management Environment) represents a breakthrough in managing TLS (Transport Layer Security) certificates. This protocol automates the process of obtaining, installing, and renewing TLS/SSL certificates, which are crucial for securing network communications. TLS certificates provide authentication and encryption, ensuring that data transferred between users and servers remains private and secure.
We are thrilled to announce the release of Stalwart Mail Server 0.5.2, which brings two significant advancements: the integration of the ACME protocol for automatic TLS certificate deployment and support for the HAProxy Protocol. These features mark a substantial step forward in our commitment to enhancing the security and efficiency of Stalwart Mail Server.
