SMTP over SSL/TLS Encryption Method

SMTP over SSL/TLS Encryption Method refers to the method by which the Simple Mail Transfer Protocol (SMTP) is secured using either the Secure Sockets Layer (SSL) or its successor, Transport Layer Security (TLS). When SMTP is used over SSL/TLS, the connection between the mail client and the mail server is encrypted from the very beginning of the session. This encryption ensures that email contents, login credentials, and other sensitive data are transmitted securely.
