Hi I want to users can access only via TLS to our MTA system,both for sending mail and fetching mail. Of course I have configured TLS in main.cf and users can connect via TLS,but if users do not set "TLS" option in own mail client,also they can connect to system. For pop3 server I have setup dovecot. Which option should I set in postfix and dovecot for this purpose ?
Thanks in advance
