i have to integrate zimbra CS in one company, that have their mailserver - postfix with openldap(accs for mail,samba share,windows ad). this mail server is backuped with netbackup, so there are a lot of servers working together.
is it possible to install zcs and this zcs will use postfix and emails from 1.server, ldap from 2.server and zcs is running on 3.server??
this mail server has about 1000 mail accounts, so it is quite difficult to migrate them.
new server for zimbra is SunFire X2100 with RHEL5.
