Postfix stable release 3.3.1, and legacy releases 3.2.6, 3.1.9, 3.0.13 for CentOS and RHEL 6,7

The latest Postfix releases are now available in self-preservative and include the following fixes.

Fixed in Postfix 3.3:
Postfix did not support running as a PID=1 process, which complicated Postfix deployment in containers. The "postfix start-fg" command will now run the Postfix master daemon as a PID=1 process if possible.

Segfault in the postconf(1) command after it could not open a Postfix database configuration file due to a file permission error (dereferencing a null pointer).

Postfix 3.2.0 stable release added to EL6 and EL7 repositories

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.
