I want to setup Zibmra correctly for 'Perfect Forward Secrecy' support.
I've read this
TLS Forward Secrecy in Postfix
Zimbra & SSL ciphers hardening
Ajcody-MTA-Postfix-Topics - Zimbra :: Wiki
In the last one I read,
The other variable/options for the "Postfix SMTP Server policy - SASL mechanism properties" you will need to know about are: forward_secrecy Require forward secrecy between sessions (breaking one session does not break earlier sessions).
But, I still don't see or understand how to specifically enable it for Zimbra ZCS 8.0.6.
What postconf/zmconfig/etc commands, or other edits, do I need to make to enable it?
