Step by step easy guide to enforced TLS on postfix needed

Hi all

I am trying to configure a centos server with postfix to only allow enforced TLS email to be sent to a certain number of domains.

If the domain isn't in the list then the email shouldn't send and if the server at the other end doesn't accept TLS then it shouldnt send either.

I have tried to follow a few online help guides but struggling to make it work as even if I add the lines to main.cf and master.cf the email still gets through when I use the "mail -s Test email test@test.com" command to both TLS and non TLS servers.

Can you please help me from scratch to get this sorted.

thanks

Have a look of this link:

By the way, have you restarted mail deamon after the changing?
