Question : Configuring SSL for Postfix without TLS support

I am tying to configure Postfix server to answer email request on any specific port with SSL enable. So far I have gathere that we can configure postfix to use TLS support which requires email client to issue STATRTLS command.

Here are the master.cf of postfix that i am working with

smtp      inet  n       -       -       -       -       smtpd
submission inet n       -       -       -       -       smtpd
#  -o smtpd_enforce_tls=yes
#  -o smtpd_sasl_auth_enable=yes
#  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
smtps     inet  n       -       -       -       -       smtpd
#  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
#  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#628      inet  n       -       -       -       -       qmqpd
pickup    fifo  n       -       -       60      1       pickup
cleanup   unix  n       -       -       -       0       cleanup
qmgr      fifo  n       -       n       300     1       qmgr
#qmgr     fifo  n       -       -       300     1       oqmgr
tlsmgr    unix  -       -       -       1000?   1       tlsmgr

flush     unix  n       -       -       1000?   0       flush
proxymap  unix  -       -       n       -       -       proxymap
smtp      unix  -       -       -       -       -       smtp
# When relaying mail as backup MX, disable fallback_relay to avoid MX loops
relay     unix  -       -       -       -       -       smtp

Answer : Configuring SSL for Postfix without TLS support

This did not solve the issue. Email client still had to issue STARTLS command to get a secure channel.
