How to filterQuery-based Distribution Groups???

Hi,
I am trying to create filters/exceptions to a Query-based Distribution Group without moving the individual from the OU.  

My Setup:
Windows 2003 Server - Standard
Exchange 2003 Server - Enterprise Edition

Query-based Distribution Group

LDAP filer:
(&(!cn=SystemMailbox{*})(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(!(homeMDB=*))(!(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*))) )))

I want to exclude certain mailboxes/email addresses from the Query-based Distribution Group.  Is this possible?  If so, how can I accomplish this?  Thanks in advance for all your help.

Bob

You can use the Exchange extension attributes (extensionattribute1-extensionattribute15) to set a property on those accounts you wish to include or exclude and edit the LDAP filter to take those fields into account.

Example LDAP filter:

(&(!cn=SystemMailbox{*})(& (mailnickname=*)(objectClass=user)(extensionAttribute15=list1_include))
