title: 'Use TLS for SMTP AUTH'

description: |-
    Postfix provides options to use TLS for certificate-based
    authentication and encrypted sessions. An encrypted session protects the
    information that is transmitted with SMTP mail or with SASL authentication.
    To configure Postfix to protect all SMTP AUTH transactions
    using TLS, see <weblink-macro link="http://www.postfix.org/TLS_README.html" />.
