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 my yum repos 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.
