Hi everyone,

I am looking for zimbra migration from postfix email server with cyrusimap database.

Set up consists of a postfix email server ( ) , CentOS Directory server ( ). All the users are authenticating to email server via Directory server. I mean to say that if users wanna read the emails from web email client ( squirrelmail ) they are going to authenticated form directory server box.

Now I wanna change to zimbra (

Is it possible to use the same authentication mechanism from directory server. ?? ???
Can I migrate all the user mailboxes from old to new zimbra. ????
Also will I be able to migrate address book and preferences of the users to new Zimbra...

Any Ideas would be appreciated .....
