Drop support for RHEL/CentOS 5 in upcoming iRedMail release?

Dear all,

We plan to drop support for RHEL/CentOS 5 in upcoming iRedMail release. Here
"drop support" means doesn't support NEW installation on it, not stop supporting
iRedMail servers which still running on it.

Two questions to help me understand what the situation is:

*) Are you guys still prefer RHEL/CentOS 5 for NEW mail server?
*) Which version of RHEL/CentOS are you running?

Here's our tracking since iRedMail-0.8.4 which was released on March 26, 2013:

Installations <-> Distribution and Release Version

3305 CentOS 6
731  CentOS 5
147  Red Hat Enterprise Linux 6
137  Red Hat Enterprise Linux 5
41   Scientific Linux 6
3    Scientific Linux 5

P.S. Upcoming iRedMail release will use EPEL yum repo on RHEL/CentOS 6 by default,
but not on RHEL/CentOS 5, because packages in EPEL for RHEL/CentOS 5 is really out
of date. Looks like upstream has no plan to bring it up to date. And RHEL 5 is in
End of Production life cycle:

We should drop support for it to reduce our workload and bring you better support for
RHEL/CentOS 6.
