Explanation
TLS (Transport Layer Security) is the standard protocol used to encrypt SMTP traffic between email gateways (mail servers), commonly referred to as STARTTLS or SMTPS. It secures the transport channel so that email content is encrypted in transit. PPTP is a VPN tunneling protocol, SSH secures remote shell sessions and file transfers, and HTTPS secures web traffic - none are designed for email gateway-to-gateway encryption.
