TLS only via SASL

[gaby]

Hi
I want to set postfix to use TLS (certificates) only my sasl clients send email.
I want to not use TLS,only for SASL clients,only when they send email.
I use sasl authenticated for my users with plain text.

/etc/postfix/main.cf:
    smtpd_recipient_restrictions =
      permit_mynetworks
      permit_sasl_authenticated
      reject_unauth_destinationI use PAM/etc/sasl2/smtpd.conf:
    pwcheck_method: saslauthd
    mech_list: PLAIN LOGIN
