[Exim] sender_reject equivalent in Exim4

Hi,

Another Exim4 question (which seems to be running OK now). Following
worked nice in Exim3:

sender_reject_recipients = partial-cdb;/etc/exim/cdb/sender_reject.cdb

This wont (according to the docs) work with Exim4. So how do I bypass
that? I want to specify *.domain.tld to block mail from all addresses in
all hostnames under domain.tld.
