    Hi,
    I found an error:
    ———————————
    service auth {
    executable = /usr/libexec/dovecot/auth
    unix_listener /var/spool/postfix/private/auth-client {
    group = postfix
    mode = 0660
    user = postfix
    }
    ———————————
    unix_listener ends with “auth-client” but when you configure postfix:
    “postconf -e ‘smtpd_sasl_path = private/auth'”

    It should be : “postconf -e ‘smtpd_sasl_path = private/auth-client'”
