Hello All, I am running Postfix for quite a while now. It works fine! no problems! I even don't have any spam! On my internal network I have Thunderbird sending mail encrypted (ssL/TLS) to Postfix/courier. It works fine too! But now I want to try something else. I want to have Postfix to transfer mails securely over the internet to another mailserver with ssl/TLS capabilities. (Mailserver to Mailserver not client to mailserver) What do I have to do to make this work? Thank you in advance for your answer and knowledge greetz.
