By default, you have a lookup table 
(/etc/postfix/ldap/ that includes only Kolab Users 
(i.e. that are supposed to also have an actual mailbox).

Choose a user that is supposed to be delivered to Google Apps, and 
verify whether his/her email address is being locally delivered:

- postmap -q doe at 
- postmap -q doe at ldap:/etc/postfix/ldap/

If either or both results in any sort of output, your Kolab server is 
(wrongfully) concluding the user is a local user (rather than a Google 
Apps user).

That said, however, looking at what a default Kolab installation 
includes (in settings, and so forth), any such user that is "local" for 
postfix should also have a mailbox created by the kolabd service. So I'm 
a little bit confused.

Perhaps you could tell us how the users on Google Apps have been added 
to the Kolab server. You could include the output of:

   $ ldapsearch -x -h localhost -D "cn=Directory Manager" -w YOURPASS -b 
"dc=your,dc=rootdn" "(mail=doe at"
