Please be aware that with CentOS 6 you will not be able to run current 
and futur safe TLS configurations out of the box, e.g. for IMAP with 
STARTTLS or a webmailer.
"Still supported" does not mean "state of the art encryption included".
Even CentOS 7 is not at the top of it. We are currently investigating 
Ubunto 16.04 LTS in comparison to CentOS 7 and Ubuntu seems to be winning.
Anyway whether we like it or not it is time to get accustomed to
