[Exim] ldap wildcard

Hi,

i got a ldap query for the domainlist relay_to_domains like this:
domainlist relay_to_domains =
ldapm;ldap::///cn=mailspool,ou=hosts,ou=systems,ou=departements,dc=bla,dc=bl
ub,dc=net?relayDomain?sub?(relayDomain=$domain)

this is working but only for domains without a wildcard like *.bla.blub.net

does somebody know what is to do to get this working?

thanks in advance!
christian
