SMTPS (Simple Mail Transfer Protocol Secure) is a method for securing the SMTP using transport layer security. It is intended to provide authentication of the communication partners, as well as data integrity and confidentiality.
SMTPS is neither a proprietary protocol nor an extension of SMTP. It is a way to secure SMTP at the transport layer, by wrapping SMTP inside Transport Layer Security (TLS). Conceptually, it is similar to how HTTPS wraps HTTP inside TLS.
