Postfix stable release 3.4.0, and legacy releases 3.3.3, 3.2.8, 3.1.11, 3.0.15 for Red Hat Enterprise Linux and CentOS 6 and 7

The latest Postfix releases are now available in my yum repos and include the following fixes.

The main changes in Postfix 3.4.0 are listed below. .

- Support for logging to file or stdout, instead of using syslog. Logging to file solves a usability problem for MacOS users, and eliminates multiple problems with systemd. Logging to stdout eliminates a syslogd dependency when Postfix runs in a container.
