Are you under the impression that CentOS is writing security patches for obsolete and unsupported versions of Postfix? That is not the case. There is a big difference between bleeding edge and obsolete, and you are firmly in the obsolete (as in not support, not patched, not secure) camp. The last update to 2.6 was over 5 years ago (Feb 2014) and that is a significantly newer version that you are running (Mar 2010). -- 'They were myths and they were real,' he said loudly.
