Edit the postfix master.cf:

vim /etc/postfix/master.cf

Uncomment the following lines:

smtps inet n – – – – smtpd
-o syslog_name=postfix/smtps
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
# -o milter_macro_daemon_name=ORIGINATING

*leave milter commented.

Now restart postfix for changes to take effect:

/etc/init.d/postfix restart
