Hi Guys !
What do i have to install and configure in order to enable SSL encryption in the postfix mail server. My server is Redhat 7.3 (intel). Once it is working, the old way (plain text) will be working too ? or only SSL mode. Does it mean that outlook will be configured with "secure password option"
Is this option confident to use it out of the firewall or is better to block the 110 port from outside to the server ?
