Hi everyone (zimbra staff especially),

I know theese questions have been asked, but some time has passed, so I will ask them again...

Is Zimbra production ready - if not when will it be?
What to do to change zimbra packages with distro packages (on RHEL, CentOS, Debian) - if there are some packages not to change - which and why?
What hardware do I need for about 2000 users (200 regular users, and rest are restricted /just email - pop3 and webmail/)

I am asking this because I am in proces of creating new email system which should replace Lotus Domino (v. 6.0.x), and it is, i may say that, urgent.
