we have also some domains we host in ldap only for some groupware
features and ldap authentication of other services but mails are stored
somewhere else. So we do it in the following way:

* adding an ldap attribute to the domains not meant to receive emails
* configuring ldap filter in mydestination

Since there is already the attribute inetdomainstatus (accessible via
kolab-webadmin) we use this and set it to suspended. Then we configure
in mydestination.cf:

query_filter = (&(associatedDomain=%s)(!(inetDomainStatus=suspended)))

hope this helps.

Best regards
Jan
