Today, the stable version of Postfix 3.2 was officially released. I have added packages for EL6 and 7 in my repositories.
In this release includes the following changes and new features:
The main changes in no particular order are:
Elliptic curve negotiation with OpenSSL ≥ 1.0.2. This changes the default smtpd_tls_eecdh_grade setting to "auto", and introduces a new parameter tls_eecdh_auto_curves with the names of curves that may be negotiated.
